Abstract: 1,130,969. Measuring surface roughness photo-electrically. RESEARCH ASSOCIATION FOR THE PAPER & BOARD, PRINTING & PACKAGING INDUSTRIES. June 5, 1967 [July 13, 1966], No.31403/66. Heading G1A. The roughness of a sample of paper, which affects its printability by a gravure process, is measured by holding it in contact with a surface of a glass block, directing light on to the surface at an angle greater than the critical angle, means for scanning the surface to detect light scattered by portions of the sample in contact with the surface and a computer calculating the proportion of the sample in contact with the surface. The sample 2 Fig. 2 is pressed against a surface 5 by a support 4 and illuminated by parallel light 1. An image of a small area of sample 2 is formed by lenses 13, 25 and mirrors 17, 19, 21 and 23 on a slit 27 of length equal to the size of a cell in a gravure process to be employed. The optical system rotates about an axis 31 and the lens 13 and mirror 17 move radially to scan a spiral path on the sample. The speed of rotation is varied to keep the speed of scanning independent of the radial position of lens 13 and mirror 17. The signal from the photoelectric transducer 29 is fed to the computer through a threshold circuit.

Title: Means for converting reciprocating into rotary motion and vice versa
IPC: F16H25/12
Filed: 1934-11-02
Abstract: 446,185. Cam mechanism. LILES, T. O., 711, East 11th Street, Dallas, Texas, U.S.A. Nov. 2, 1934, No. 31484. [Class 80 (iii)] Means for converting reciprocating into rotary motion and vice versa comprises shaft and sleeve members having complementary or coacting endless cam grooves each of wavelike form and anti-friction bearing means operating in said grooves. A member 15 connected by rods 14 to a source of power, carries a sleeve 10 adapted to reciprocate over a shaft 11 supported in a frame 21 by ball bearings 23 and provided, e.g. with a flywheel 13. The shaft may however be the driving and the sleeve the driven member. The sleeve is formed internally with a number of endless wave-like grooves 24, preferably of harmonic shape, and semicircular in crosssection and the shaft 11 is formed with similar grooves 25. In the spaces formed by opposed grooves are located two rows of balls 20 maintained in position by a thin spacing cylinder 18 between sleeve and shaft. With the arrangement shown, the sleeve moves axially twice the axial distance moved by the balls and two strokes, forward and back, are completed for one revolution of the shaft. The number of crests in the grooves may be varied to vary the relative motion of sleeve and shaft. The inertia of the moving parts tends to free the balls from dead centres, and the harmonic form of the grooves tends to reduce shocks. In the above mechanism, the balls are of the freely floating or drifting type as distinct from mechanisms where the ball is fixed relatively to one of the members, and it is due to this that the movement of the sleeve relative to the balls is increased.

Title: Improvements in or relating to sheet delivery apparatus
Inventor: WALKER WILLIAM EDWARD
IPC: B65H29/32
Filed: 1961-09-04
Abstract: 990,470. Sheet-delivery apparatus. WALKER (ENFIELD) Ltd. Dec. 4, 1962 [Sept. 4, 1961], No. 31687/61. Heading B6H. Apparatus for delivering sheets such as carbon blanks to a receiving station comprises perforated belts 13 passing under a suction box 11 perforated at its lower face, the sheets being released from the belt to fall on the table by cutting off the suction from the box. The sides of the box 11 have openings 15 connected to a source of suction, and within the box slides a box-shaped member 12 reciprocated vertically by cam means in time with the delivery of sheets to the belts 13 by belts 19. In the raised position of the member 12, suction is applied to the chamber 16 within the box 11 to hold sheets to the belts 13, but when the member 12 is lowered, it covers the openings 15 to cut off the suction and at the same time forces air out through the perforations in the bottom of the box 11 and in the belts 13 to cause a sheet to be released and moved down on to the receiving station. A single belt 13 may be employed or a number of belts each with its suction device 11, 12. Further, the box 11 may be reciprocated and the member 12 stationary in which event the belts are moved vertically to maintain the small gap between the belts and the bottom of the box 11. The belts 13 may move continuously or may be stationary at the time the sheets are released.

Abstract: 538,344. Automatic guns. CESKOSLOVENSKA ZBROJOVKA AKCIOVA SPOLECNOST BRNO. Dec. 8, 1939, No. 31830. Convention date, Oct. 21, 1938. [Class 119] The breech-closing spring 12 of a gun in which the breech bolt 14 is locked and unlocked by the sliding movements of the bolt carrier 5 controls the return movement of the carrier only during the initial stage, the breech closing by momentum and the block being locked by the pressure exerted on the carrier by the firing pin retraction spring 20 stressed during recoil. The invention is shown applied to a gun having a gasoperated carrier slide 5 for a tilting breech bolt 4, the slide carrying a pin 17<SP>1</SP> for engagement with a cam groove 15 in the bolt for tilting the bolt into and out of engagement with the fixed locking abutment 19. On discharge, the carrier 5 compresses the retraction spring 20 and unlocks the bolt, the projection 13 on the carrier compressing the return spring 12 which reacts to impel the carrier forwards until it is retrained by the sear 29. The carrier completes its forward movement by momentum and by the reaction of the spring 20 which actuates the carrier to effect locking movement of the breech block. The release of the sear by the trigger 30 then enables the return spring 12 to act on the hammer 11 to fire the gun.

Title: Improvements in or relating to circuits for receiving frequency-modulated oscillations
Inventor: HEPP GERARD
IPC: D21J5/00
Filed: 1947-12-02
Abstract: 636,375. Frequency mediation. PHILIPS ELECTRICAL Ltd. Dec. 2, 1947, No. 31852. Convention date, Dec. 4, 1946. [Class 40 (v)] A frequency-modulation receiving-circuit designed to reject undesired amplitude modulation without the use of limiters comprises a detector which gives an output representing both the desired FM signal and the undesired AM signal, this output being fed back to amplitude-modulate the incoming carrier wave in such sense that the undesired amplitude modulation is neutralized or reduced, whilst the desired frequency modulation is converted to amplitude modulation of the carrier and is detected by rectification. The system may be used in a switch-selective combined FM and AM receiver. In Fig. 1, the incoming wave, converted to an intermediate frequency, is amplified in the valve 2 and fed to coupled tuned circuits 3, 4 connected respectively in the grid circuits of a multi-grid valve 7. The anode voltage of this valve contains audio-frequency components due to undesired amplitude modulation, and also similar components due to the desired frequency modulation, and both these are fed back through an I.F. filter 9 to the grid of the valve 2 to amplitude-modulate the carrier. In this way, the undesired amplitudemodulation is reduced or neutralized, and the desired frequency-modulation is preserved as an amplitude modulation of the carrier in the circuits 3, 4. This is detected in the circuit of the screen grids 10, 11 and is fed to an audiofrequency stage 13. The retro-active modulating voltage may be derived by rectification of I.F. currents in the anode circuit of the valve 7. In Fig. 2 the mixer valve 15 has two anode circuits 19, 25 tuned respectively to a medium I.F. for AM reception and to a high I.F. for FM reception. When receiving AM, the switch 18 connects the secondary circuit 20 across grid and cathode of the amplifier 17, the anode circuit of which feeds through a tuned circuit 22 a rectifier 23 supplying the audio-frequency stage 13. When receiving FM, the switch 18 connects the secondary tuned circuit 26 to the grid of the valve 17 and the FM wave selected by the tuned circuit 3 is fed to a FM detector 3, 4, 27, 28. The detected FM signal together with any undesired amplitude modulation appears across the load resistor 28 and is fed to the grid of the valve 17 and after amplification in that valve is fed retro-actively to modulate the mixer valve 15 in such sense as to neutralize the undesired amplitude modulation. The desired FM signal appears at the same time as an amplitude modulation of the carrier wave in the circuit 3 which wave is fed to the rectifier 23 and thence to the audio-frequency stage 13. The stages 15, 17 of Fig. 2 may both be I.F. amplifiers, or the stage 15 may be an amplifier and the stage 17 a mixing detector as in Fig. 1. Specification 646,997 is referred to.

Filed: 1919-12-19
Abstract: 160,533. Cowell, W. J. Dec. 19, 1919, Pneumatic collectors; sweeping- machines. -Relates to street refuse collecting-machines in which rotary brushes actuated from the driving-axle of the machine are so arranged that they can be simultaneously raised from the roadway and disconnected from the driving-gear. According to the invention, the brushes are mounted in yokes and are driven by bevel-gearing, movement of the yokes to raise the brushes serving simultaneously to disengage the pinions of the bevel-gear. The invention also comprises (1) employing conical inclined brushes, (2) a tip-reservoir for the reception of the sweepings, and (3) a suction fan in the reservoir actuated from the driving-gear of the vehicle through clutch mechanism. In the form shown, two conical brushes 13 are suspended by links 6 from the vehicle chassis and are driven from the rear axle 12 by bevel-gearing 10, 11. Links 7 are operable by thrust-rods 8 actuated by gearing from a lever 18 in order either to vary the pressure of the brushes on the road, or to raise the brushes from the ground, this action simultaneously throwing out the gears 10, 11. The brushes sweep refuse into the path of a suction nozzle 28 on a detachable tube 26 connected to a pipe which enters at an acute angle a pipe 25 delivering into a reservoir 22. The pipe 25 may terminate in a series of baffles, grids, or coils, or may be led under water. The suction is produced by a stream of air driven by a fan 30 through thepipe 25, the air thus blown in, together with the suction air from the tube 26, being expelled at 24 after filtration and disinfection. The fan 30 is belt-driven from the drive-shaft 36, an idle wheel 32 being provided upon which the belt may be drawn by a lever 34 to put the fan out of action. The reservoir 22 may be raised round its pivot 21 by quadrant and pinion gear 37 operable from a hand-wheel 38 to facilitate emptying through the rear door 23.

Title: Process for the manufacture of foamed structures from platicized polyvinyl chloride compositions
IPC: C08J9/12
Filed: 1959-09-21
Abstract: Foamed structures of polyvinyl chloride are made by subjecting a plasticized polyvinyl chloride composition in a mould to sub-atmospheric pressure so as to cause release of the gas adsorbed during preparation of the composition, expansion of said gas and foaming of the plasticized mass, and causing the foamed mass to gelatinize by high frequency electrical heating.  A plasticizer may be used which itself is polymerizable.  In the examples, foamed structures are prepared from compositions containing (1) polyvinyl chloride, dibutyl phthalate and monophenyl urea as stabilizer and (2) polyvinyl chloride, dibutyl phthalate, tetraethylene glycol dimethacrylate and lauryl peroxide.ALSO:Foamed structures of polyvinyl chloride are made by subjecting a plasticized polyvinyl chloride composition in a mould to subatmospheric pressure so as to cause release of the gas adsorbed during preparation of the composition, expansion of said gas and foaming of the plasticized mass, and causing the foamed mass to gelatinise by high frequency electrical heating.  The mould has a cover plate and a base plate which constitute electrodes connected to a high frequency alternating current generator and side walls made or covered with a material having suitable dielectric properties so as to be heated by the high frequency field.  A suitable material for making the mould walls is a polyester resin or epoxy resin while polyvinyl alcohol, natural rubber or silicone rubber may be used as a covering material.  After the gelatinisation the mould can be exposed to the atmosphere and the foamed structure cooled at atmospheric pressure.  This is due to the fact that there are no longer present any closed cells containing gas under reduced pressure, the closed bubbles having burst open during the gelatinisation but only after it has advanced to such an extent that the foamed mass cannot collapse.  Depending on the subatmospheric pressure used, the process yields foamed structures of densities as low as 0,05 g./c.c.  It appears that the air adsorbed on the polyvinyl chloride particles during the usual processing operations suffices to cause the paste to expand the required amount, no blowing agent or low boiling liquid being necessary.  A suitable composition is polyvinyl chloride (having a K-value of 75) 100, dibutyl phthalate 70, and monophenyl urea (as stabilizing agent) 0,2 parts by weight.  Mixtures of polyvinyl chloride with another resin may also be used to make the foamed structure.  In this connection a plasticizer may be used which is itself polymerizable, either alone or with one of the usual plasticizers for polyvinyl chloride.  A composition of this type comprises plasticized polyvinyl chloride 100, dibutyl phthalate 30, tetraethylene glycol dimethacrylate 50, and lauryl peroxide 1,5 parts by weight.
