Title: Improvements in or relating to compressed-air inlet-valves for internal-combustion engines
IPC: F01L9/10
Filed: 1922-05-30
Abstract: 202,750. Doxford, R. P., and Keller, K. O. May 30, 1922. Valve gear.-In an engine supplied with liquid fuel under high pressure, the fuel system being maintained under a steady pressure, a compressed-air inlet valve 15 for starting is actuated by the pressure of the fuel supply acting upon a column of liquid fuel. The valve 15, which admits compressed air to the cylinder 10 from a pipe 14, is normally closed by a spring 16 and is opened by means of a hydraulic piston 17 on the admission of fuel to a pipe 19 by a piston valve 23. The fuel is admitted from the highpressure fuel-supply system to the valve 19 by a pipe 21 and is exhxausted by a pipe 22. The valve 19 is actuated by a cam 25 on an enginedriven shaft 26, the cam acting upon a lever 24 provided with an adjustable fulcrum 27 to enable it to be put into and out of action. Specification 17446/11 is referred to.

Title: Electrical wave shaping device
IPC: H03K5/06
Filed: 1963-04-18
Abstract: 987,959. Pulse circuits. UNITED STATES ATOMIC ENERGY COMMISSION. April 18, 1963 [July 9, 1962], No. 15294/63. Heading H3P. A circuit for reversing a waveform in time comprises a delay line 48 arranged as one of the arms of a balanced bridge 52 and having electronic switching devices 60 connecting the output of a pulse generator to individual points along the line. As described, resistors 54, 56, 58 form the other arms of the balanced bridge. The voltage waveform shown ia applied across the bridge and causes a travelling wave to be propagated along delay line 48. The voltage waveform is used to trigger a phantastron time delay circuit 57 and a blocking oscillator 59 so as to provide a positive pulse at a predetermined time of the input waveform. When this positive pulse is applied to the anodes of diodes 60 each capacitor of the delay line will receive a voltage step equal to the difference between the peak voltage of the pulse and the instantaneous voltage of the travelling wave. This will result in a travelling wave, reversed in time as shown, being propagated along the delay line 48 to output terminals 62, 64. In a known circuit shown in Fig. 2, intermediate points of two delay lines 28, 32 are connected together by switching diodes 38. The diodes are normally reverse biased but can be turned on by a pulse from a phantastron and blocking oscillator (not shown) so as to propagate along line 32 a wave reversed in time relative to that travelling along line 28. The waveform shown is thus available across the terminating resistor 44. The time base of the output waveform may be expanded or compressed relative to the input waveform by using lines of different transit time. Selective portions of the input waveform may be emphasized or eliminated by adjusting the relative attenuation of the various switching circuits.

Title: Photographic shutter unit and camera comprising the same
IPC: G03B9/64
Filed: 1962-04-24
Abstract: 937,945. Shutter mechanisms. AGFA A.G. April 24, 1962 [April 29, 1961; Aug. 9, 1961], No. 15652/62. Class 98 (1). A shutter mechanism, incorporating a delayed action device for optional use, has a blade. Opening and a blade-closing ring which move in the same direction in running down the shutter, with a latching means operable by a moving part of the shutter, which in the setting movement latches, and in the running down movement unlatches, the exposure value setting means. The arrangement is intended for use with cameras having automatic exposure regulation. As shown, the mechanism has a bladeopening ring 3, a blade-closing ring 4, and an aperture/shutter speed control ring 5, all spring- loaded. Rings 3 and 4 can make contact via respective lugs 10, 9. Ring 5 controls the diaphragm leaves 18. Ring 3 also has a pin 23, cooperating with a manual control 26, and a lug 24 co-operating with the escapement 28 of the delayed action mechanism 45-60. Control ring 5 has a ratchet portion 15, in which can engage the tooth 44 of a latch 41 pivoted on a fixed pin 42. The measured exposure value is taken into account by pivoting the arm 13 of ring 5 in the direction of arrow 65, prior to or together with setting the shutter. In addition the delayed action mechanism is set by turning lever 51 in the direction of arrow 67. Lever 26 is now turned in the direction of arrow 66, to set the shutter, causing rings 3 and 4 to turn clockwise, tensioning the springs 6, 7. During this rotation, pawl 41 engages its tooth 44 in ratchet 15, to restrain ring 5. Also, tooth 45 of pawl 46, which has been bearing on the lug of ring 3, falls into a recess 32 therein. Continuing movement of lever 26 causes pin 23 to reach an escape point. Just prior to this, lug 24 engages latch 27, which liberates the escapement- 28 of the delayed action mechanism, and so sets this in action. After pin 23 is released, ring 3, and thus also ring 4, are still held by pawl 46. As the retarding mechanism runs down, tooth 45 eventually lifts out of recess 32, thus releasing ring 3 to return under loading and so open the shutter blades. Running down of ring 4 is further delayed by another retarding arrangement 33-38, in which a pin 33 engages against the periphery of a projection 29 of ring 4. When the delayed action is not set, tooth 45 is retained out of engagement with recess 32. Fig. 2 (not shown) is a modification having a different latching arrangement.

Title: Improvements in or relating to apparatus for cutting round holes in paper or card
Filed: 1947-06-16
Abstract: 632,970. Hand punches. GAUSDEN, A. H. June 16, 1947. No. 15862. [Class 31 (ii)] In an apparatus for cutting a hole in paper or card a cam and follower connection is provided between a circular cutting element and a supporting guide for the cutting element, whereby on application of axial pressure to the supporting guide the guide is moved axially relatively to the cutting element which is moved angularly relative to the guide to cut a circular disc from the paper. As shown applied to a hand punch, the body 10 forming the supporting guide, which may be made of ebonite or like material, has a screwed plug 13 at one end against which bears a spring 21. The other end of the spring acts upon a hollow cylinder 17 forcing it against a screwed plug 14 at the other end of the body 10. The cylinder 17 has a helical cam groove 18 corresponding to one revolution and in which rides a screw projection 19 secured to a reinforcing ring 20 on the body ; the ring may be omitted if the body is of metal. In screwed connection with the cylinder is the cutter 15 which may have an internal cutting edge 16 or an external one. In the hollow of the cutter 15 is an ejector spindle 22 which normally projects from the cutting edge 16 as shown. The end 25 of the spindle is urged by a spring 23, the other end of which rests upon a plug 24 in the cylinder 17. Mounted on the plug 14 is a cap 26 with a pocket clip which is removed for use and mounted on the plug 13. When manual axial pressure is applied to the body 10, the spindle 22 moves inwardly and the cutter 15 is rotated to cut the paper by the interaction of the screw 19 and cam groove 18. After axial pressure has been released, the spindle 22 returns to its normal position and ejects the cut-out disc from the hollow of the cutter. When the apparatus is employed to punch statistical cards, guide means, such as shown in Fig. 6 may be employed. The card to be punched is located by hooks 32 and stops 33 on a backing 30, to which is hinged a guide 34 having apertures 35. An indicator 36 may be provided to assist identification of the apertures 35. Beneath the backing 30 is provided a compartment for cards having a hinged lid 39.
