Patent GB-1128622-A (GB)
Title: Improvements in or relating to piston engines pumps or compressors
IPC: F04B39/00
Filed: 1964-12-02
Abstract: 1,128,622. Pistons. HUMBER Ltd., and A. STEVENS. 11 Feb., 1966 [2 Dec., 1964], No. 49074/64. Heading F2T. A piston 11 and connecting rod 10 are interconnected by a resiliently flexible strut 12 which is rigidly connected at one end to the piston and at the other end to the rod. The strut may be of spring steel and as shown in Fig. 2 has a perforated foot 14 at one end cast into the piston and a foot 15 at the other end clamped in a groove 16 in the connecting rod by a screw 17. In a modification, Fig. 3 (not shown), the strut is cast into both the piston and connecting rod.

Title: An intermittent driving mechanism
IPC: F16H27/10
Filed: 1967-10-30
Abstract: 1,147,845. Intermittent gearing. NATIONAL CASH REGISTER CO. 30 Oct., 1967 [27 Feb., 1967], No. 49177/67. Heading F2Q. An intermittent drive mechanism comprises, in a casing 12, a disc 18 secured on an input shaft 14 and having a driving dog 24, and a rotatable output disc 28 carrying equi-angularly spaced plungers 36 axially movable into and out of the path of the dog 24 under the control of a fixed plate 60 located between the discs 18, 28 and having a cut-out 70 defining an arc of driving engagement. As the shaft 14 is uniformly rotated manually or by a motor, the dog 24 travels round a circular groove 72 in the plate 60 until on entering the cut-out 70 at 70a it engages one of the plungers 36 and carries it to the edge 70b where a ramp 76 acts on the inclined head 74 of the plunger to cam it out of the path of the dog 24. By this time another plunger 36 has entered the cut-out 70 ready to be engaged on the next revolution of the dog 24. The advance of the output disc 28 thus depends on the arcuate extent of the cut-out 70 and the number of plungers 36. The plate 60 and disc 28 are replaceable to alter the step angle. The plungers 36, which may be of trapezoidal or circular cross-section, are urged axially by springs 40 which react on a plate 46 bolted to the disc 28, flanges 38 limiting the plunger travel. The output disc 28 may carry a cam 82 to operate a switch (86) (Fig. 3, not shown) or may be connected to a tubular output shaft. To stop the shaft 14 after one revolution, a stop 78 is slidden into the path of a dog 26 on the disc 18. Two or more mechanisms having different step angles may be driven by a single input shaft 14. Reverse rotation of the shaft 14 is prevented by the abutment of a plunger 36 against the edge 70a of the cut-out 70.

Title: Hologram record pressings
IPC: H04N5/76
Filed: 1966-11-02
Abstract: 1,139,955. Holography; cinematography. RADIO CORPORATION OF AMERICA. Nov.2, 1966 [Nov.22, 1965], No.49230/66. Headings G2C and G2E. A duplicate hologram record pressing is made by recording a hologram, or succession of holograms, as a relief pattern on a master surface 416 and transferring by pressing the relief pattern on the master surface on to a record blank. Light from a laser 400 is split into two beams by a semi-reflecting mirror 404, one beam 406 illuminating a frame 440 of a motion picture film 434 and the other beam 405 forming the reference beam. A hologram of this frame is recorded on a small area of the surface 416 which may comprise a silver emulsion, a photo resist, or a thermoplastic material. The surface 416 is then rotated and translated, and the film advanced one frame prior to recording the next frame, so that the film is recorded as a spiral centred on the axis of the disc-shaped surface 416. The apparatus described may be modified to record colour motion pictures, either in three concentric spirals one of each of the colours red, blue, green, or in one spiral, every third hologram being of the same colour. After the surface 416 has been fully recorded, it is developed or processed if required in order to obtain the holograms in relief, then covered with a thin metal coating, and then a pressing is made therefrom. The duplicate pressing may be transparent or coated with a highly reflective metal film, and is read by illuminating with laser light, information so obtained being displayed directly on a screen, converted to electrical form for use in a data processing system, fed to an image intensifier, or picked up by a television camera arrangement and displayed on a monochrome or colour television screen, Figs. 13, 14 (not shown).

Title: System for altering a data distribution display
IPC: G01R13/22
Filed: 1972-10-27
Abstract: 1403390 Particle analysis systems COULTER ELECTRONICS Ltd. 27 Oct 1972 [4 Nov 1971] 49659/72 Heading G1N The invention relates to a Coulter type particle analysis system in which pulses in each amplitude/ size range pass through respective "window circuits" and are counted by accumulator (integrator) circuits. The integrator signals are cyclicly connected to a C.R.T. or plotter to provide a number-V- size distribution curve display. According to the invention a predetermined (zero shift), bias may be added to each integrator output to cancel noise signals or to make the display show deviation from a standard curve. As shown, Fig. 1 pulses from sensor 14 are applied to "windows" 16 feeding integrators 21. . 24 connected through switches 51. .54, (sequenced by clock 44) to a C.R.T. display 40. Positive/ negative bias from potentiometers 111. .114 is added to the integrator outputs through summing resistors 91. .94. A typical switch circuit using both series and shunt F.E.T.'s simultaneously is illustrated in Fig.3 (not shown). The bias may be used to improve particularly the leading edge of the display curve by offsetting the signal due to diluent only in the sensor. Alternatively The biases may be set to give zero deflection with a standard solution in the sensor (which will obviously give a mirror image distribution curve with zero signal from the sensor). Thus a standard mirror image signal may be set up from a reference curve superimposed on the screen.

Title: Cone crusher
IPC: B02C2/04
Filed: 1963-12-18
Abstract: 1,060,473. Gyratory crushers. KLOCKNERHUMBOLDT-DEUTZ A.G. Dec. 18, 1963, [Dec. 28, 1962], No. 49963/63. Heading B2A. [Also in Division F2] A cone-crusher comprising an axiallymovable breaking head 4 driven through an eccentric is provided with a labyrinth seal between the eccentric drive and the head, such seal consisting of interfitting cups 27..30 of such length that when the head is in the highest position sufficient overlap is left for sealing, and when it is in the lowest position the upper seal cups associated with the head 4 do not strike against the lower cups associated with the drive. The cups 27, 28 are secured to a carrier 31 rigidly connected indirectly to the eccentric bush 6, and the upper cups 29, 30 have respective flanges (32, 33, Fig. 3, not shown), by which they are connected to the head 4, a conical skirt (32') protecting the seal from damage by the material being crushed. The gaps (34 .. 36) are narrow, but wider than the clearance between the eccentric drive and the head to avoid grinding the cups against one another. The outer cup 28 has markings (37, 38) for the top and bottom limit positions of the head. To prevent the head from rotating with the drive when ioling, a brake is provided for the head comprising a Cardan connection between a freewheel coupling (43, Fig. 2, not shown), in the neck portion of the breaking head and the king pin 16 of the crusher. Between the head 4 and an adjustable piston 15 is a torsion bar 46 having teeth (44, 45) at its two ends, and which engages with its upper teeth (44) in corresponding inner teeth (47) in the hub (48) of the freewheel coupling (43) mounted on the breaking head 4. The lower teeth (45) of the bar (46) engage teeth (49) of a pinion (50) rigidly mounted in the middle of a sphered socket (14) of piston 15, and a spring 55, guided in a groove 56 in the king-pin 46, is provided externally on the piston 15. Thus the piston, and hence the breaking head, is held by the king pin in the direction of rotation of the eccentric, the length of the groove 56 permitting axial movement of the piston and braking head. The coupling (43) is mounted in the neck of the breaking head 4 and has a ratchet wheel (51) coacting with rollers (52) to permit rotation in only one direction. The breaking head is displaceable in the presence of tramp metal against the action of an annular spring 17 and the width of the crusher gap 18 between the lining 5 of the head and the liner 3 is adjustable by operating a shaft 20 to raise and lower the head by a spindle 19 engaging in a thread in the adjustable piston.
