Abstract: 677,662. Percussive drills. PINAZZA, G. April 13, 1950 [May 12, 1949], No. 9101/50. Class 124. In a percussive tool actuated by the centrifugal forces developed by rotary eccentric masses the reciprocating element is provided with at least one axial hole on the end remote from the striking end for lubricating purposes. As shown, a disc 54 having a diametral slot 52 is driven by a flexible drive through a dog clutch 60 which may be disengaged by a handle 68. A pin 50 in the slot 52 is rigidly fixed to 'a pin 48 to which is secured a pair of eccentric masses 42 having a bearing surface 46. A reciprocating element B, which, at its lower end, may have grooves for rotating a tool C, has an enlarged part co-operating with the bearing 46 and extends upwardly to a cylinder 10 which co-operates with a fixed piston 12, the piston and cylinder having grooves and ridges to prevent relative rotation : Oil from a reservoir 84 is led to the outer surface of the cylinder 10 down which it flows until it enters a groove 90 having radial holes 92 through which the oil penetrates until it reaches an axial hole 94 in the element B. From this axial hole the bearing surface 40 is lubricated, the oil finally reaching a chamber and by passages 102 lubricating a ratchet gear 30. The oil from the reservoir 84 passes through porous plugs which act as filters, Fig. 4 (not shown). In a modification, Fig. 5, the element B has a small inner cylinder 118 into which the oil is forced from a reservoir in the piston 12<SP>1</SP> by way of a perforated pipe 120. Two pairs of eccentric masses 42<SP>1</SP> rotating in opposite directions replace the single pair, and oil passes from one to the other through a tube.

Title: Improvements in or relating to pulse responsive circuits
Inventor: LUSCHER PAUL
IPC: H01H51/32
Filed: 1960-03-15
Abstract: 897,051. Automatic exchange equipment. SODESCO SOC. DES COMPTEURS DE GENEVE. March 15, 1961 [March 15, 1960], No. 9185/60. Class 40 (4). [Also in Groups XIX, XXXVI and XL (c)] A relay circuit which is operated by each group of a train of spaced groups of alternating pulses, for use in counting the number of groups of timing pulses in a telephone system, comprises a circuit 3, 4 resonant to the pulse frequency and connected base of a transistor 5 having a relay 6 in its collector circuit, the emitter-collector path being shunted by a capacitor and resistor 7, 8 in series so that circuit is operated by the group of pulses. Bursts of a mains frequency A.C. voltage consisting of about 15 cycles and spaced from each other by about 20 seconds are applied between earth and the two wires of a telephone line a, b while the line is in use so that by counting the bursts the duration of use may be determined. These bursts are applied to the resonant circuit so that the negative half-cycles render the transistor conducting and progressively discharge capacitor 7. After a number of cycles the voltage at the collector decreases to a value sufficient to operate the relay, the latter remaining operated until the end of the burst. The relay may operate a counter and the delay in operating the relay provides immunity against operation by spurious signals.

Title: Improvements in the thermal protection of dual voltage electric motors
IPC: H02H7/085
Filed: 1955-03-30
Abstract: 766,032. Control of A.C. motors. GENERAL ELECTRIC CO. March 30. 1955 '[March 31, 1954], No. 9291/55. Class 38(3) A bimetallic protective element for a dual voltage motor is subjected to the same current at both operating voltages, and will therefore open the motor circuit at substantially the same temperature of the motor windings whichever voltage supply is used. As shown, for operation at the lower voltage, the running windings 3, 4, of the motor are connected in parallel, and a bimetallic disc 14 and heater 16 are in series with winding 4. A starting winding 9 is disconnected by a centrifugal switch when the motor reaches a predetermined speed. Deflection of the disc 14 will diengage a movable contact 13 from stationary contacts 12, 21, and so de-energize both running windings of the motor. When operating at the higher voltage, the disc 14, heater 16, and both the windings 3, 4, are connected in series so that the bimetallic disc carries substantially the same current as in the previous arrangement. As shown, the current in the starting winding 9 passes through the disc 14 and heater 16. However, in another arrangement, the starting circuit does not include the disc or heater, Fig. 3 (not shown). In a further modification, the starting current flows through the disc but not the heater.

Title: Improvements in and relating to the recording of data upon continuously moving photographic film
IPC: G03B17/24
Filed: 1950-04-17
Abstract: 687,584. Recording data on moving films. EVANS, B. S., and RUDGE, R. P. April 17, 1951 [April 17, 1950], No. 9334/50. Class 98 (i). [Also in Group XIX] Apparatus for recording a time scale on a film which is continuously moved in a photographic camera, e.g. for recording the finish of races, and which is separate from the camera and can be placed in the field of view thereof, comprises timing markings and means for successively illuminating said markings at selected times so that images thereof are recorded on the film, the period during which each marking is illuminated being sufficiently short to enable sharply defined images to be recorded. As shown, an opaque disc 2 bearing stencil numbers from 0 to 99 is mounted on a shaft 7 driven by a motor 5 to make one revolution per second, and an opaque disc 3 bearing stencil numbers from 0 to 59 is driven from the shaft 7 to move one number for each revolution of the disc 2. An intermittently-energized discharge lamp 15 having a reflector 16 and a condenser 17 illuminates through an aperture 19 in a mask 18 one number group on each disc, an image thereof being projected on to the margin of the continuously-moving film in a photo-finish camera 33 by either a semi-reflector 35 or a smaller mirror obscuring a marginal portion of the object-field. The shaft 7 is driven preferably through a single stage of planetary gearing by an electric motor in which the armature revolves about a centre and rotates in the same sense about its own axis. On the shaft 7 is also lever 9 pivoted at 10. When this lever drops down the cam step 8, a driving pawl 12 which is pivoted on the lever and spring-urged anticlockwise, drives a ratchet-wheel 13 clockwise to move the disc 3 on one number, return movement of the disc being prevented by a ratchetpawl 14. Alternatively, the drive between the discs may comprise a shaft which is driven by bevel gears from the shaft 7 and which carries a single turn worm meshing with a worm-wheel on the shaft of the disc 3. At the end of a complete revolution of the disc 3 from the zero position, a peg 27 on the movable spring contact of a switch 25, 26 moves down into a notch 24 in a cam 23 on the disc shaft thereby stopping the motor and discharge lamp, both of which are operated from a crystal-controlled generator and are synchronized so that the lamp flash occurs each time a new group of numerals is presented. Contacts in parallel with the switch 25, 26, and closed by the starting pistol or by opening of the starting gate or trap, may be provided to permit of recording the duration of the race from start to finish. Instead of an electric motor, a clockwork motor may be used while the intermittently-energized lamp may be replaced by a continuously-lit lamp and a moving shutter.

Abstract: 788,636. Travelling band filters. AMERICAN AIR FILTER CO., Inc. March 27, 1956 [April 1, 1955], No. 9507/56. Class 8(2). [Also in Group XXXVII] A gas filter web 3, Fig. 1, is intermittently traversed across the dust-laden gas stream from a supply spool 4 to a take-up spool 5 by an electric motor 6 on the closing of a switch 23, Fig. 2, actuated by a relay coil 22 controlled by a switch 21 which in turn is controlled by a timing motor 19 which accumulates time by means of a timing motor 16 and an associated cam-actuated switch 18. The motors 16, 19 each have a cycle of 12 mins. and drive cams 17, 191 which actuate the associated switches 18, 21 for a duration of 7 seconds. During normal filtration a switch 12 is held closed by a vane 14 responsive to gas pressure from the blower 7, and since switch 18 is held closed for 7 seconds at the end of each 12 minute cycle of motor 16, the motor 19 is also energized during these 7-second periods. Near the end of the tenth such period motor 19 is in position to close switch 21 for a period of one second whereupon relay coil 22 closes switch 23. During the next closed period of switch 18 and running period of motor 19, switch 21 remains closed for a period of 6 seconds making 7 in all during a period of about 20 hours. The relay coil 22 may be energized at will by a manual switch 24, and when the blower stops, vane 14 opens switch 12 to stop the timer motors and opens a switch 11 to light a warning lamp 13. The web 3 is of matted or interwoven glass fibres which on the supply and take-up rolls 4, 5 are in compressed condition but fluff-up when in the gas filtering conduit.
