Abstract: 679,987. Trueing grinding wheels. HAYES, J. G: March 21, 1951 [March 21, 1950], No. 6942/50. Class 60. [Also in Group XXII] Means for producing spherical surfaces by turning comprise a tool-carrying member pivotally mounted on a toothed wheel and means for imparting angular movement to the toothed wheel about its centre, the tool-carrying member being guided to maintain it in constant angular relationship with the rotation axis of the work during said angular movement of the wheel. The device may be applied to trueing a grinding wheel and is adapted to be clamped in a tool rest 15, Fig. 1, of a lathe or other machine tool to operate on a workpiece 18 held in a chuck 19. The tool 24 is mounted on a bar 21 carried between a pair of plates 10, 12, and constrained to have a circular motion with the bar maintaining parallelism with the centre axis of the lathe. Spacers 14, Fig. 3, maintain the cover plates in correct spaced relation, and a pair of toothed wheels 17 are adjacently set in recesses in the lower plate 10. Radial grooves 34 in the toothed wheels are arranged to be parallel and carry adjustable studs 20 which engage holes in the tool-bar 21. A pinion 27, set in another recess in the plate 10 engages with the two toothed wheels 17 and is secured to a spindle 28 which extends through the upper plate 12. A worm wheel 29 is secured to the top end of this spindle and a worm mounted in bearings on the top of plate 12 has a milled extension piece for rotating it and thus moving the too] in its circular path. The device is set up witb the centre line joining the wheels 17 in alignment with the spindle axis of the machine. Adjustment of the studs 20 to a different radius results in the tracing out by the tool of such new radius.

Title: Improvements in or relating to electromagnetic relays
IPC: H01H50/28
Filed: 1959-02-27
Abstract: 884,280. Electromagnetic relays. COMPAGNIE DES MACHINES BULL. Feb. 27, 1959 [March 6, 1958], No. 6947/59. Class 38 (5). A relay armature is secured to one end of an initially flat return spring having its other end secured to a surface of a support member oblique to the armature so that the spring is continuously stressed and the armature bears on a fulcrum line of the relay yoke. As shown in Fig. 7, the armature 3 is riveted at 11 to the initially-flat rectangular spring 2 which is riveted at 10 to a member 5 secured at 13 to the yoke 7. When assembled the spring biases the armature 3 so that the forked contact end thereof engages fixed contacts 8a and the other end rests on the end 15 of the yoke 7. The contact pressure may be adjusted by bending the member 5. When the armature 3 is attracted it pivots about the yoke end 15 and its contact extensions engage fixed contacts 8b on a member 14 which also holds the coil former 6 on the yoke 7. Since the spring 2 is in line with the yoke end 15 there is no longitudinal movement of the armature. The electrical connection to the armature is completed through the yoke 7, member 5 and spring 2. Figs. 5 and 6 show alternative forms of the spring 2, member 5, and yoke end 15. When the spring 2 is secured below the armature, as in Fig. 6, it may be made of bronze or other non-magnetic material and act as a spacer to maintain a residual gap between the armature and core.

Title: Improvements in the manufacture of optical elements from polymerizable material
IPC: B29D11/00
Filed: 1944-04-14
Abstract: A method of making an optical element such as a prism from polymerizable material, e.g. styrene, cyclohexyl methacrylate or methyl methacrylate, comprises rigidly securing together mould parts 10, introducing the polymerizable material into the mould, advancing the polymerization through an initial hardening stage, releasing the mould parts from one another, and finally advancing the polymerization to substantial completion, the mould parts remaining attached to the material as the <PICT:0604274/IV(a)/1> latter shrinks.  The mould parts may be secured together by an alloy 13 such as Wood's Metal or "Belmont Alloy," which may be removed as by fusion or by being mechanically scraped or pried therefrom.  The initial polymerization may be carried out at 25-40 DEG  C. for one to two days and the final polymerization at 80-90 DEG  C. for one day.  At the end of the second stage of hardening the plates 11 and 12 may be removed from the hardened product by immersing the mould and the formed prism into a hot water bath containing a surface active agent such as "Aerosol." In a modified method the removal of the alloy 13 is effected automatically by the higher temperature used in the second hardening stage.

Title: Apparatus for controlling the period of hiring or use of tennis courts and the like
IPC: G07F17/00
Filed: 1923-03-10
Abstract: 213,749. Brown, R. March 10, 1923. Time checks and time registers.- Tennis courts and the like are rendered available for play for a predetermined time by the payment of a fee which removes an obstruction from a winding device for tightening the net. A casing 36 is attached by screws 37<a> to one of the net posts 38 and contains a drum 28 on which the net straining wire 29 is wound by means of a handle 14 through gearing 16, 17. The engagement of a cup-shaped head 10 on the handle with a polygonal boss 15 on the gear wheel 16 is normally prevented by an obstructing slide 8 which is connected by a band 6 to a one-way clutch 7 on a shaft 5a. Rotation of the shaft 5<a> after prepayment, to the extent of one tooth of the clutch 7 for each coin inserted withdraws the slide 8 step by step against a spring 41 until the full fee is paid and the winding handle can engage the boss 15. A pawl 19 engages ratchet teeth 9 on the slide to hold it in its withdrawn position. The band 6 is adjustable according to the number of coins to be paid. When the net is stretched, a knob 42, Fig. 2, is pressed to move the stirrup end 20<a> of a lever 20 into engagement with the wheel 17 to lock it. A spring- controlled rod 21 slidable in the stirrup end 20<a> at the end of a complete revolution of a snail cam 23 drops from the high to the low point of the cam and disengages the lever 20 from the wheel 17 allowing the net to slacken. The cam 23 is driven by clockwork and makes one revolution in the predetermined period of hiring. A locking device 30 enclosed by a screw-cap 31, Fig. 1, is provided on the drum spindle so that the groundsman may lock the apparatus whether the net is taut or slack. Each coin inserted in a holder 1<a> rotated by a knob 2 engages and rotates through the space of one tooth a wheel 5 on the shaft 5<a>. The coins inserted are recorded on a counter in a casing 32, the counter being actuated by gears 32<a>, 32<b>, one of which is on the spindle 5a.

Title: An improved method of and apparatus for controlling the boring tools in deep boring plants operating with rotary boring devices
IPC: E21B19/08
Filed: 1935-03-06
Abstract: 456,447. Deep - boring. MULLER, F., 170, Lainzerstrasse, Vienna. March 6, 1935, No. 7082. Convention date, March 6, 1934. [Class 85] In rotary deep-boring, the torque and bottom pressure are controlled by regulating devices either of which is adapted to be put into or out of operation independently, while when they operate in conjunction, each is at all times effective. A further independent regulating device may be provided dependent on the speed of rotation. In Fig. 1, a motor 1 drives the boring machine 3 through a tooth-pressure or other dynamometer 2 while the free end of the drill cable 5 is connected to a load measuring device 4. The dynamometer 2 and the device 4 are connected through a pivoted lever 16 to a switch 14 controlling a reversible electric motor 10 driving cable drum 9 whereby variations in the torque or drill pressure cause raising or lowering of the drill. The switch 14 is also manually operable. In the form shown diagrammatically in Fig. 2, the cable drum 61 is connected through worm gearing 60 and differential gears 58 to oppositely running hydraulic turbines 52, 53, supplied by pump 47 through connected needle valves 54, 55, one of which carriesa piston 57. The boring machine 20 is capable of yielding about the drill rods 21 and acts on a pivoted spring - pulled jet tube 41 through piston 22, a fluid link, piston 32, lever 37 and rod 39. The free end of the drill cable is connected to a piston 28 in a pivoted cylinder 27 to act on the jet tube 41 through a fluid link, piston 25, lever 36 and rod 38. Variations in torque or drill pressure or both move the jet tube to deliver through pipe 43 or 44 to one side of the piston 57 thereby moving the needle valves 54, 55, to vary the supply to the turbines 52, 53, and drive the drum 61 to raise or lower the drill rods. Cocks 24, 31 are provided in the fluid links. In a modified construction, the rods 38, 39 are arranged on opposite sides of the jet tube 41, pins on the latter entering slots in the rods. In Fig. 6, a pump 82 circulates fluid through pipe 83, valve box 84 containing spring-loaded cone valves 94, 95, and cooler 97 ; branch pipes 85, 91, are connected through valve 86 and pipes 87, 90, to opposite ends of a cylinder 89 containing a piston 88 through which the drill rods are raised or lowered. The valve 94 is adjusted by nuts 99, 100, according to the desired drill pressure while a torque-measuring device acts through lever 102 and cam 103 on the valve 95, variations in drill pressure or torque causing adjustment of the valves 94, 95, to effect raising or lowering of the piston 88. The valve 86 may be reversed to apply pressure to the drill when commencing boring. In Fig. 7, a further valve 108 is provided and is actuated through lever 111, cam 110 and chain &c. 109 whereby, as when widening the boreholes, the tool is lowered a given amount at each revolution. The cam 110 may be conical and slidable to give variable action.

Title: Improvements in or relating to remote control devices
IPC: G05D3/12
Filed: 1946-03-09
Abstract: 609,267. Electric selective signalling. PHILIPS LAMPS, Ltd. March 9, 1946, No. 7438. Convention date, June 27, 1941. [Class 40 (i)] In a system for signalling or controlling by electric means the transmitter in different predetermined positions renders effective different combinations of transmission channels under control of which the receiver, which is designed to render the channels ineffective in the same combinations is driven, the arrangement being such that, if the transmitter is set to a position between two signalling positions, the receiver stops in the predetermined position corresponding most closely to that of the transmitter. In the known arrangement of Fig. 2, the transmitter connects a combination of three channels to one of two motor windings 10 (or to relays controlling such windings) according to the direction in which it is rotated, and the motor then drives the receiver until the latter has opened the same three channels. With this device, if the transmitter is set to a position between two definite signalling positions, the receiver runs indefinitely. According to the invention, the positions and the relative sizes of the make portions of the transmitter disc, the break portions of the receiver disc and the brushes are chosen so that the receiver can be made always to stop in the position nearest to that of the transmitter whether the latter is in a correct signalling position or not. Overrunning is prevented by arranging that the motor is braked as soon as its circuit is interrupted. In a coarse and fine adjustment system, Fig. 9, a seven-channel twenty-one position transmitter 13 is geared to a tenchannel one hundred position transmitter 23, the latter running fifteen times as fast as the former. The receivers are similarly geared together and are driven through a differential gear 21 by two motors 20, 30, of which the former is controlled by the seven-channel system and preferably runs at a higher speed than the latter which is controlled by the tenchannel system. Alternatively, the actual motor speeds may be equal, the effective speeds being made different by the gearing 21. Where the transmitter is motor-driven, as in the case of tuning a wireless receiver from a remote point provided with a tuning indicator, means are provided to limit its speed. The Specification as open to inspection under Sect. 91 also gives a general description of a hydraulic analogue in which the transmitter and receiver comprise cam discs controlling valves in the transmission conduits. This subject-matter is not included in the Specification as accepted.
