Title: Improvements in or relating to variable speed power transmission
Inventor: HAYES FRANK ANDERSON
IPC: F16H61/662
Filed: 1929-09-02
Abstract: 344,061. Variable speed gearing. HAYES, F. A., Middletown, New Jersey, U.S.A. Sept. 2, 1929, No. 38212/30. Convention date, May 7, 1929. Divided on 343,988. [Class 80 (ii).] In variable-speed gearing of the torus disc type operating by the precession of intermediate rollers, the rollers are supported with their axis of rocking at a permanent angle to the planes of the discs. When a roller 19, Fig. 3, is inclined to its tracks on the discs 10, 15, it precesses or creeps sidewise like the front wheel of a bicycle, tracing out a. spiral. The axis, n, n, Fig. 2, of the trunnions 24 of the yoke 22 carrying the roller 19 is inclined at a permanent angle to the planes of the discs 10, 15. The effect is that when equilibrium is disturbed by a control member, precession goes on automatically until a definite position is reached, that shown in Fig. 3, with the axis p, p of the roller intersecting the axis m, m of the gearing. The gear control member thus remains unstressed in its new position, and the gear unit is torque-responsive. A practical embodiment forming a part of the twin gearing described in Specification 343,988 is shown in Fig. 4. The axis of the yoke trunnions 24 is shown supported at a small angle in trunnion blocks 33 rockably supported in the rockers 28 described in Specification 344,062. The gear control member may be an hydraulic piston as described in Specification 344,066.

Title: Improvements in electric time switches
Inventor: HORSTMANN KENNETH JOHN
IPC: G04C23/22
Filed: 1956-12-14
Abstract: 824,687. Time switches. HORSTMANN GEAR CO. Ltd. Nov. 27, 1957 [Dec. 14, 1956], No. 38226/56. Class 38 (5). The switch comprises a rotating dial plate with adjustable " on " and " off " tappets, the " on " tappet being engageable with a lever to move the switch " on," and a spring-loaded retaining lever which holds the switch in that position in the event of a second engagement of the lever by an " on " tappet before the switch is moved " off by an "off" tappet. When the " on " tappet 13 is moved clockwise to engage a lever 14 pivoted at 15, the lever tilts counter-clockwise and lowers a lever 17 pivoted thereto at 19, this action stressing a spring 38 attached to lever 17 and a lever 34, and positioning a step 20 on lever 17 below an arm 40 of the lever 34 pivoted to a base-plate 4 at 36. Eventually tappet 13 disengages the lever 14 which is rotated clockwise by spring 38 into engagement with a stop 46. At the same time, lever 17 is raised and carries lever 34 with it. This movement of the lever 34 causes a button 50, carried at the rear of plate 4 by a pin 48 on the lever 34, to allow a contact blade to engage a fixed contact (Fig. 4, not shown). Also, the arm 40 is raised above a catch 29 on a lever 27 which is thus pivoted clockwise by a spring 31 to latch the arm 40, even though the step 20 on lever 17 may be moved down again by a second engagement of lever 14 by the same or a further " on " tappet. The switch is opened when an "off" tappet 11 engages a lever 12 which carries a pin 22 located in a slot 18 in lever 17 and an arm 26 which engages an arm 27<SP>1</SP> of lever 27 so that steps 20 and 29 are both removed from below lever 34 which is tilted clockwise by spring 38. The mechanism may be applied to the switch of Specification 744,612. The switch may be manually tripped open by moving to the left an arm 43 on a lever 41, thereby causing an arm 41<SP>11</SP> thereon to engage an arm 25 on the lever 12 which is thus moved to release the lever 34. Movement of the arm 43 to the right causes an arm 41<SP>1</SP> on lever 41 to tilt lever 34 counter-clockwise to reclose the contacts, the lever 34 becoming latched as before. Specifications 329,633, 331,083, [both in Class 38 (v)], 373,554 and 500,670 also are referred to.

Filed: 1973-08-14
Abstract: 1478849 Vehicle bumper assemblies ROAD RESEARCH Ltd 1 Aug 1974 [14 Aug 1973] 38405/73 Heading B7J A vehicle has a bumper assembly comprising a bumper 4, an arm pivoted to the bumper and to the vehicle body or chassis at a point remote from the bumper, and a resilient shock absorber 6 pivoted to the arm and to the vehicle body or chassis at a point spaced from the pivotal connection between the arm and body or chassis, whereby, in use, when the bumper 4 is subjected to a force above a predetermined value the shock absorber 6 operates to permit the arm to move to cause the bumper to be displaced in a direction having a horizontal component. Fig. 1 illustrates a rear bumper assembly in which the bumper 4 is pivoted on a pair of downwardly and rearwardly extending arms 5 and a shear pin 15 is provided between each arm and the bumper to prevent the bumper from pivoting on the arms so that its rear face is normally held in a vertical position. The shock absorber 6 connected between each arm 5 and the vehicle chassis 1 is an hydraulic piston and cylinder device which yields in compression such than when the bumper 4 is struck with a force above a predetermined value the bumper swings downwardly and forwardly with the arms 5 and moreover the pins 15 shear causing the bumper to pivot on the arms 5 in an anticlockwise direction as viewed in Fig. 1. A similar arrangement to that illustrated in Fig. 1 may be used on the front of the vehicle (Figs. 2 and 4, not shown). In the front bumper assembly shown in Fig. 5 the bumper 4 is pivoted to a pair of substantially horizontal arms 21 themselves pivoted to arms 23 fixed to the vehicle chassis 1. An hydraulic shock absorber 6 yielding in compression is associated with each arm such that when the bumper 4 is struck with a force above a predetermined value the bumper 4 swings upwardly and rearwardly with the arms 21. A net 20 is connected between the bumper and chassis 1 to catch a pedestrian contacted by the bumper. The hydraulic shock absorbers 6 may be connected into an hydraulic circuit responsive to the vehicle braking system and/or accelerator and/or ignition device so that the operation of the shock absorbers varies as a function of the speed and/or acceleration or deceleration of the vehicle.

Filed: 1958-12-31
Abstract: 878,495. Selective printing. NORMAN, W. E. Dec. 22, 1959 [Dec. 31, 1958; Feb. 2, 1959], Nos. 38554/58 and 3691/59. Class 100(4) Selective printing apparatus controlled by successive signals in which relative movement between a character bearing endless belt or band and a printing station positions each character to be printed successively at the printing station is arranged so that the relative movement between the printing of two successive characters is equal to the shortest distance between them measured along the belt. A character bearing band TR passing over pulleys 3, 4 can be driven in either direction by being clutched by a clutch CLR or CLL to oppositely rotating flexible drives 9, 10 of a motor M. Printing is effected by a hammer 12 when a character is correctly positioned while the band TR is being traversed at a constant speed along a platen 1. The band TR is inked by rollers 15 operated by solenoids 16. The arrangement is such that after printing of a character the band TR is moved to position the next character selected in the direction required to give it the shortest movement the control being effected by electric circuits receiving signals from a punched or magnetic tape or a computer or teleprinter or like source and by signals derived from photo-cells P1, 2, 3, as windows W pass a lamp Z. Photo-cell P3 is a homing device while the impulses derived from P1 and P2 drive a counting tube in either direction according to the direction in which the windows W are moving. The appropriate clutch CLR, CLL is actuated to drive the belt TR in the required direction for the next character by comparing the potential significance of each signal with that of the previous signal and of a constant reference potential. When coincidence between the character signal and the counting tube signal indicates that the selected character is in the printing position the actuating clutch CLR or CLL is disengaged and breaks BL, BR are applied to stop the belt. The hammer 12 is now actuated when wipers wipe as the band moves along the platen 1 indicate that the correct spacing of the character has been achieved. In a preferred embodiment two bands TR are provided which constantly move from the ends of the platen to the centre and back and print alternately during their left to right movement. Printing may be effected by projecting a form of radiant energy through cut-out portions on the band so that said energy is transmitted in the form of a character on to suitable sensitized paper. The second Provisional Specification shows other embodiments including one in which a separate band is provided for each character space and printing of the characters of a whole line can be effected simultaneously.

Title: Acyloxy Thiazolidine Compounds and process for their Manufacture
Inventor: WOODWARD ROBERT BURNS
IPC: C07D513/04
Filed: 1966-08-30
Abstract: 1,155,018. Acylated thiazolidine derivatives and processes for their preparation. R. B. WOODWARD. 30 Aug., 1966 [10 Sept., 1965; 9 Dec., 1965 (2); 13 Jan., 1966; 3 Feb., 1966], No. 38571/66. Heading C2C. Compounds of the formula in which Ac 1  represents an acyl group, X stands for the disubstituted carbon atom of the thiazolidine ring, Ac 2  represents the acyl radical of an organic carboxylic acid and R 1  represents a free or functionally converted carboxyl group, may be obtained by reacting a saturated cyclic α- hydrazino-thioether of the formula wherein R a  and Rb represent the residues of alcohols and R 2  is hydrogen or a hydrocarbon residue, with an oxidizing agent capable of furnishing an acyloxy group of the formula -OAc 2 . The reaction may be effected by treating the starting material with, e.g. at least 2 mol equivalents of the oxidation reagent, generally in the presence of a diluent and optionally in an inert atmosphere and/or under increased pressure. A resulting mixture of isomers may be resolved into individual isomers, e.g. by fractional crystallization or adsorption chromatography, and resulting racemates may be resolved into optical isomers by forming a mixture of diastereoisomeric salts with optically active, saltforming agents, separating the mixture into the diastereoisomeric salts and converting the isolated salts into the free compounds. The carboxyl moiety R 1  may subsequently be chemically modified by conventional methods, for example an esterified carboxyl group may be converted to a free carboxyl group or a free carboxyl group may be converted to a functional derivative, many of which are referred to, e.g. ester, amide, azide, hydrazide or nitrile. The acyl radicals Ac 2  may be derived from aliphatic or aromatic carboxylic acids, which acids may be substituted; suitable oxidation reagents capable of furnishing such acyloxy groups include heavy metal carboxylates, e.g. lead tetracarboxylates, thallium-III-carboxylates, or mercury-II-carboxylates, which may be formed in situ and acyl hypohalites (which are generally formed in situ). The only specific examples of the radicals Ac 1  and X which are described are the t-butyloxycarbonyl radical and a dimethyl-substituted carbon atom respectively; the hydrazino starting materials may be converted into the corresponding hydrazoxo or azo derivatives during the reaction, which derivatives may themselves be used as starting materials and converted into the desired products of the invention by treatment with an oxidizing agent of the type described above, or by hydrolysis.

Abstract: 1,026,224. Ammunition fuzes. CONTIGEA S.A. Sept. 24, 1964 [Sept. 30, 1963; Aug. 31, 1964], No. 39013/64. Heading F3A. An electric fuze to be mounted between the body and the tail of a missile has a body 1 divided by a partition 4 into chambers 2, 3. A ring 7 supporting a charge 10 is screwed into the forward end of chamber 2 and a detonator holder 19 is pivotably mounted within chamber 2. The partition 4 houses a primer 11, which has a casing 12 of electrically conducting material from which a spindle 13 passes through an insulating liner 14 to bear against a metal plate 15, Fig. 1, within the chamber 3. During storage, the drum is held with the detonator 22 out of alignment with the primer by a rod 17, Fig. 2, the rod being thrust forwardly by a spring 18 bearing against a collar 16. A second rod 26 surrounded by an insulating sleeve 29 abuts the holder 19 and extends through a metal plate 30, insulating material 31 and the base of the chamber 3. A conductor 33 connected to a piezo-electric generator (not shown) extends into a bushing 32, which contacts the plate 30. Thus the generator is short-circuited through the bushing 32, plate 30, rod 26 and drum 19. On launching the projectile, rod 17 sets back due to inertia and releases the holder 19, which is then rotated by its spring 24 until a notch (23) is aligned with rod 26, thus freeing the rod 26 and bringing the detonator 22 into alignment with the primer 11. Return movement of the rod 17 is prevented by an elastic member moving into a groove 37 and the rod 26 is thrust forward into notch 23 to lock the holder 19 in the armed position, the short circuit of the generator being broken.
