Abstract: 712,334. Reciprocating motors. ELMEG ELEKTRO-MECHANIK GES. Sept. 12, 1951 [Sept. 12, 1950], No..21488/51. Class 35 [Also in Group XXII] An electro - magnetic impact tool comprising a core movable in a magnetic coil system and carrying a press tool, the core being moved in one direction under the influence of the coil system to cause the tool to strike a workpiece and being returned in the opposite direction under the influence of another coil system or by one or more springs is characterized in that the core is further controlled by a coil system in such a manner that the tool when moved in the striking direction is not returned immediately but remains in the striking position and exerts a pressure on the workpiece. Energization of the striking coil 2 and pressure 3 by means of a lever 13 impels the core 4 downwards and maintains the tool against a workpiece on the base plate 14. The coil 2 may be de-energized by a switch 15 operated by the core, the switch position being adjustable to vary the impact, and a time switch in the circuit of the coil 3 allows of adjustment of the time during which pressure is maintained. The core comprises magnetic and non- magnetic portions and is preferably slotted.

Title: Goniometer
IPC: G01C1/02
Filed: 1959-06-24
Abstract: 888,748. Measuring angles. ZEISS-SHIFTUNG, CARL, [trading as ZEISS, CARL. [Firm of]]. June 24, 1959 [June 25, 1958], No. 21653/59. Class 97(3). An instrument for accurately measuring the angle of a workpiece comprises two arms 8, 12, Fig. 1, which rotate about a common axis 30, arm 8 being coarsely adjusted, e.g. in intervals of a degree, by a gear clutch, and the arm 12 being finely adjusted by means of a step-down gearing mounted in the housing 1 below the gear clutch. The arm 8 is carried by a disc 4 having 360 radial teeth on its lower face to mesh with similar teeth on the upper face of a fixed disc 2. To disengage discs 2, 4, an arm 11 is moved by its handle 11a about axis 30 whereupon due to the threaded engagement of a shaft 7, rigid with arm 11, with a fixed sleeve, the shaft 7 is raised so that disc 4 may rotate freely about shaft 7. The angular position of arm 8 is indicated by a pointer 29 on housing 1 co-operating with a scale 28 on disc 4. For fine adjustment, a disc 14 carrying a gear 18 is rotated about a pin 15, the angular setting being read by means of index mark 17 on housing 1 against a scale 16 on disc 14. The gear 18 meshes with a gear 20 which rolls by means of pin 22 along a curved rail 21, the rolling being controlled by a pair of tapes 24 which are attached at one end to fixed sectors 25a, 25b, pass partly around their curved surfaces and the curved surface,of a roller 23, carried by gear 20, and are fixed to the roller 23 at their other end. Another tape 26 is similarly connected both to roller 23 and a sector 27, Fig. 4, so that the latter is rotated about axis 30 causing flexing of its spring pivot 13. The arm 12 is carried by sector 27. In a modification, Fig. 9, the disc 14 has a spiral scale 16a co-operating with an index 41 slidably mounted in a holder 43. On adjusting the holder 43 so that index 41 is moved through an angle u compensation may be effected for variations in the stepdown gearing caused for instance by variable tape thickness. The teeth on gear disc 4 may be undercut so as to render them somewhat elastic to compensate for inaccuracies in the position of one or more teeth.

Abstract: 1381786 Springs; dampers AMETEK Inc 9 May 1972 21664/72 Heading F2S In a self-erecting means, Fig. 1, e.g. for elevating a camera or extending equipment from a space capsule, the normally axially-compressed helical spring ribbon which erects to become a tube 4 is supported at one end on a member 10 bearing a damper such as an unwound spring 76, Fig. 2 (or a ratchet and spring-rod (102, 108), or a blade-and-fluid damper (126, 128)) in a reel 16 for a line 18 which is linked by eyes 22, 24 to the other end of the spring ribbon coil 4 and anchored at 26 on the support 10. The reel 16 has end plates 56, 60 with a handle 84 for winding-in the line 18 and thus compressing and retracting the tubular coil 4. The plates 56, 60 rotate with a keyed shaft 52 journalled in end plates 32, 34 secured by a tie bar 36 and a bracket 40 to the support 10 and flanking a drum 48 for receiving the line 18 as shown. The drum is keyed to the shaft at 50 and the damping spring 76 is secured for action between the shaft 52 and the fixed plate 34 (by way of its housing 72 and a fixing 80). When the tubular coil 4 is wound down (unwinding the spring 76 to the state illustrated) a plate 90 is slid into slots 86, 88 in the drum plates 32, 34 to lock the coil in the retracted storage position until withdrawn to allow the coil to re-erect. When extended, the coil 4 can be eased out of cups 8, 12 and used as a pole. The damper may comprise a ratchet wheel (102) secured to the shaft (52) with spring rods (108) extending from the end plate 34 to engage its teeth. Alternatively, a casing (122) containing hydraulic fluid is secured to the plate 34 and has arcuate blades (126) interdigitating with blades (128) secured to a plate (130) which closes the casing (122) and is fixed to the shaft (52).

[Also in Groups XXX and XXXI] A vehicle trailer is provided with a pair of telescopic legs, upon which it may be supported, by expanding the legs (see Group XXXI). The legs are expanded by fluid pressure supplied by a manually operated pump, which has an inlet connection 53b from a fluid reservoir, the pump having two piston rods 40 and 41, each having fast therewith a smaller piston 42 operating within a small chamber 48, and slidingly mounted and pressed against a collar 51 by a spring 52, a larger piston 43, operating within a larger cylinder 50. Shoulders 50a are provided at the bottoms of chambers 50. The large cylinders 50 have discharge passages 57a, controlled by ball valve 57b, 57d and 57e, the small cylinders 48 have discharge passages 57f through non-return valves 57g, 57h to 57d, 57e and thence to the expanding legs, the outlet passages 57a associated with the piston rod assemblies 40 and 41 being connected one to each leg respectively. The inlet connections from the passage 53b to the cylinders 48 and 50 are controlled by non-return valves 58 and 56 respectively. The valve body has three parallel bores 62, 63 and 64, the outer of which 62 and 63, communicate with the passages 57d respectively and are connected to the inner bore 64 through passages 66 controlled by non-return valves 65. The inner bore 64 communicates with the passage 53b. Flow of fluid from 57d to 64, that is, an exhaust flow from the expanding legs, is controlled by a spool 67 having ports 68 which may be brought into register with the passages 66, the spool and valves 65 being actuated from a spindle 73 connected to a handle 69. The piston rods 40 and 41 of the pump are connected to a crosshead 44 and may be reciprocated by a handle. During the initial stage of expanding the legs, both pistons 42 and 43 discharge fluid. When the fluid pressure reaches a certain value, that is, when the legs touch the ground, the pistons 43 are held against the shoulders 50a, the springs 52 being compressed, and only the pistons 42 supply fluid to the legs. The legs are held expanded by a ratchet and pawl mechanism, and, to retract the legs, the handle 69 is manipulated to open the valves 65 and bring the apertures 68 and 66 in to register, the handle 69 at the same time retracting the pawls on each leg.
