In this subclass non-limiting references (in the sense of paragraph 39 of the Guide to the IPC) may still be displayed in the scheme. F16P1/00Devices protecting or preventing injuries to people F16P1/00Safety devices independent of the control and operation of any machine protective devices for the eyes or ears, worn on the body or carried in the hand, A61F9/00, A61F11/00 F16P1/005Guards for rolls in calendering or other roll machines, e.g. nip guards, finger guards F16P1/02Fixed screens or hoods F16P1/04Screens or hoods rotating with rotary shafts F16P1/06specially designed for welding F16P3/00Safety devices acting in conjunction with the control or operation of a machineControl arrangements requiring the simultaneous use of two or more parts of the body F16P5/00 takes precedence F16P3/001Safety devices for guarding the human operator of punch presses or like machine tools performing an opening and closing travel F16P3/003by application of a specific control arrangement, e.g. specific switching systems or two-hand control F16P3/005having a movable screen or a sensor influencing the switching system F16P3/006having a screen moving with the machine and moving the operator out of danger, or restraining the operator, without influencing the switching system F16P3/008Devices for directly stopping or interrupting the drive or gear in case of danger to the machine, e.g. devices with clutches F16P3/02Screens or other safety members moving in synchronism with members which move to and fro F16P3/04for machines with parts which approach one another during operation, e.g. for stamping presses F16P3/06in which body parts of the operator are removed from the danger zone on approach of the machine parts F16P3/08in connection with the locking of doors, covers, guards, or like members giving access to moving machine parts F16P3/10in which the operation of locking the door or other member causes the machine to start F16P3/12with means, e.g. feelers, which in case of the presence of a body part of a person in or near the danger zone influence the control or operation of the machine F16P3/08 takes precedence F16P3/125Guards for rolls in calendering or other roll machines, e.g. nip guards, finger guards F16P3/14the means being photocells or other devices sensitive without mechanical contact F16P3/141using sound propagation, e.g. sonar F16P3/142using image capturing devices F16P3/144using light grids F16P3/145using magnetic technology F16P3/147using electro-magnetic technology, e.g. tags or radar F16P3/148using capacitive technology F16P3/16with feeling members moved by the machine F16P3/18Control arrangements requiring the use of both hands F16P3/20for electric control systems F16P3/22for hydraulic or pneumatic control systems F16P3/24for mechanical controls F16P5/00Emergency means for rendering ineffective a coupling conveying reciprocating movement if the motion of the driven part is prematurely resisted F16P5/005Overload protection by energy absorbing components, e.g. breaker blocks, shear sections F16P7/00Emergency devices preventing damage to a machine or apparatus F16P1/00, F16P3/00, F16P5/00 take precedence; indicating means, see the appropriate classes F16P7/02by causing the machine to stop on the occurrence of dangerous conditions therein devices in bearings affected by abnormal conditions F16C
