IPC: F02N15/06
Filed: 1928-11-26
Abstract: 321,342. Whitney, M. P. Nov. 26, 1928. Turning.gear.-In a starter drive comprising a driving member such as a pinion 7 movable longitudinally on and rotatable with a shaft 3, which is movable axially to bring the member 7 into engagement with an engine member 29, a positioning device 15 places the member 7 in forward position on the shaft 3 when the latter is retracted, but leaves it entirely free when the shaft is advanced into the starting position. As shown, the pinion 7 is threaded to engage screwthreads on the shaft 3, which slides on the splined shaft 2 of the electric motor 1. The shaft 3 is moved axially by means of a shifter arm 19 sliding on a shaft 12 and connected to a foot-operated plunger 22, which carries an adjustable screw 26 for engaging a switch 27 for the motor. The positioning device 15 is fixed on the shaft 20 and its arms 17 carry rollers 18 projecting into the path of the disc 8 of the pinion 7.

Abstract: 1,160,435. Printing processes; transfers. FUJI SHASHIN FILM K.K. 3 Aug., 1966 [4 Aug., 1965], No. 34814/66. Heading B6C. [Also in Division C7] A printing process comprising providing an electrically insulating coating layer on an electrically continuous conductive base, eliminating the coating layer in accordance with an image to be reproduced so as to expose the electrically conductive base, depositing or forming a material upon the exposed area of the base by electrolysis with the base connected as an electrode and then transferring the material so deposited or formed onto a transfer material, e.g. by pressure. The insulating layer may be (i) a photo-sensitive polymer layer which is exposed to a light image and developed, (ii) a pressure-sensitive releasable layer which is selectively removed by writing pressure applied through an adhesive sheet material (iii) a heatsensitive releasable layer which is transferred to a transfer material in contact therewith at an area heated to the softening temperature of the layer or (iv) a material which may be decomposed and evaporated selectively by heat caused by the absorption of high intensity light (e.g. laser light). The conductive layer may be metal or a base (e.g. paper or plastics material) coated with a material containing carbon block or a finely-divided metal powder dispersed in a binder. The image area may be provided with a release layer, e.g. polysiloxane or silicone oil to ease transfer of the deposited or formed material. Transfer to the transfer material may be by pressure. Examples of suitable insulating and conducting materials and of electrolyte compositions are given.

Title: Improvements in or relating to electrical speed detection systems
IPC: G01P13/00
Filed: 1953-12-21
Abstract: 785,788. Rest - or - motion indicators. IGRANIC ELECTRIC CO., Ltd. Dec. 21, 1953 [Dec. 22, 1952], No. 35483/53. Class 106 (3). In an electrical system for detecting when a variable-speed device is at rest, the device is arranged to rotate a cam 18 which operates an interrupter 10, 12, 14 of which the arm 10 is connected to an alternating current supply line L<SP>1</SP> and the contacts 12, 14 to the line L<SP>2</SP> via rectifiers and capacitors 20, 22 and 24, 26 respectively. The winding 28a of a relay 28 bridges the connections between the rectifiers and the capacitors and a smoothing capacitor 30 is connected in parallel with the winding 28a. The frequency of oscillation of the arm 10 is always less than that of the alternating current supply so that so long as the arm 10 does oscillate the capacitors 22, 26 will be charged through their associated rectifiers 20 and 24 respectively and will be discharged through the winding 28a. If, however, the arm 10 comes to rest the capacitors 22, 26 will either be completely discharged or will be charged to equal and like potentials so that current will cease flowing in the winding 28a.

Abstract: 843,280. Contacting gases with liquids. KOCH ENGINEERING CO. Inc. Nov. 14, 1957, No. 35493/57. Class 55 (2). [Also in Group XXIX] In absorption and similar apparatus wherein intimate contact is desired between gases or vapours and liquids, each deck 10, Fig. 2, is provided with a number of apertures 12 each housing a check valve 14 comprising a circular domed closure-head 16 with a peripheral flange 16a that, in the valve-closed position, sealingly engages the deck 10 around the aperture 12; the flange 16a is indented (18, Fig. 5), and depending from each indent is a curvilinear leg 20 with a foot 22 which engages the under side of the deck 10 when the valve is in the fully open position. Each valve may embody two or more legs, each of which may be slotted to reduce the resistance to the liquid flowing across each deck; one or more slots may also be disposed in each valve head to enable the gases &c. rising from one deck to another to flow through as well as being laterally distributed about the flange 16a; the legs may be punched from the valve head. The valves may be of rectilinear shape with a flat head and may co-operate with similarly-shaped deck-apertures, whilst the two legs may be of different height to permit the rising gases &c. to be directed as desired, the legs being so disposed that, when the valve is fully open, they will both be normal to the deck although the valve head will be tilted with respect thereto. Bending of one of the legs enables each valve to be assembled and dismantled. Stainless steel, aluminium or plastic material may be used for the construction of the valves.

Filed: 1946-12-02
Abstract: 619,319. Windscreen-cleaners. TRICO PRODUCTS CORPORATION. Dec. 2, 1946, No. 35680. Convention date, Dec. 22, 1945. [Class 138 (i)] Relates to the actuating arm 5 of a windcreen-cleaner having a shaft-engaging section 12 which provides a socket 20 adapted to surround and be secured to the outer end of the operating shaft. According to the invention, the front wall 26 of the section 12 has a removable portion 32, Fig. 2, defined by a weakened margin 30 which enables this portion to be detached in order to permit the section to be fitted to another type of shaft designed to pass through the section and protrude beyond the front wall thereof. When the arm is used without removing the portion 32, as shown in Fig. 2, the socket 20 fits over the head 14 of an operating shaft 13. A series of teeth 16 may be provided on the periphery of the head 14 for engaging with grooves 17 in the socket 20, and a resilient latch 21 interlocks with a shoulder 15 on the head 14 to hold the arm on the shaft. When the arm is to be used on a shaft 35 of the kind shown in Fig. 3, the portion 32 is detached so as to provide a hole 33 for the passage of the threaded end 34 of the shaft and the sleeve 36 of an attaching nut 37. In this arrangement, an insert 40, together with a thrust-receiving collar 42, which may be moulded in place within the insert, are positioned in the socket, being held in place by the resilient member 21 teeth may be provided on the periphery of the insert for co-operation with the grooves 17 in the socket. The arm is then inserted over the shaft 35 so that the tapered and serrated surface 43 of the collar engages a correspondingly-shaped shoulder 45 on the shaft. When the nut 37 is screwed on to the shaft, the sleeve 36 of the nut engages the collar 42.

Abstract: 400,448. Mechanical optical illusion toy. BONINGER, M. H., 6, Eschollbruckerstrasse, Darmstadt, Germany. Dec. 19, 1932, No. 35954. [Class 132 (iii).] A mechanically-operated toy produces the illusion of a rotating member, e.g. a sword, passing through an obstacle, e.g. a head, by the member rotating rapidly from one side to the other of the obstacle without passing through it. Manual movement of the lever 6 from left to right compresses the spring 12 and brings the projection 17 into contact with the arm 14 of a spring-pressed fork the other arm of which 13 is moved out of contact with the arm 8 which then rotates rapidly in a clockwise direction through the compressed spiral spring 12 engaging in the ends of the slot 27 in the pivoted toothed sector 10 engaging the pinion 7 secured to the shaft 2 to which is secured the arm 8. The arm 8 thus rotates from one side to the other of the stop 9 and rotates with it the arm 1, which may be in the form of a sword, from one side to the other of a pin 3 which may bear on its end a head 26. The operation produces the illusion of the sword passing through the head. The pin 3 passes through a glass cover of the toy and is removable from a bore 4 for inspection purposes. The action of the toy is reversible through another spring-pressed fork 13, 14. The toycan be used in conjunction with an advertising text.
