Abstract: 431,198. Covering cores. BLANCHET, P., and TILLIE, G., 73, Rue de Villiers, Neuilly, Seine, France. Dec. 27, 1933, No. 36417. [Class 109] [See also Groups VIII and X] Mouldings, flexible beadings, or welts made up of strips such as ribbons, bands, cords, slivers, threads, skin, leather, or fabric, are produced in a machine in which each element is drawn from a supply, made to travel in a separate path, coated with adhesive, passed through a drying device, and brought to a place where it is assembled with and secured to the other elements, and where the composite strip is shaped. Preferably the elements pass through devices which guide each element into position relative to adjacent elements and then cause them to adhere in the required conformation. The shaping devices may have grooves to allow passage to elements carrying tacks, or to cords which are to be incorporated in the composite strip. For changing the shaping or other devices the machine frame may have rails on which are removably placed carrier members formed on or secured to the shaping devices. Each side of the machine may have similar or different shaping or other devices. The composite strips may be used in furniture, upholstery, and for covering joints in motorbody construction. As shown in Fig. 1, the strip comprises three elements A, B, C, the inner one carrying tacks P. It is made as shown in Fig. 2. Strip A passes through the adhesive appliance 2 and drying chamber 33, and then to joining and shaping devices. Strips B, C from rolls 39, 59, pass through adhesive appliances 23, 21, and the drying chamber 33, to the assembling devices. The adhesive flows from a container 13 to device 2 and thence by overflow pipes to devices 21, 23. Strip A is guided through device 2 by a curved sole plate and spring-pressed upstanding plates arranged so that the middle portion of the strip is not coated. Strips A, B are assembled at 50 by guideways and vertical rollers, and pressed together and shaped by rollers 51, 52. Strip C is assembled at 68 by guide-plates and pressed round the other strips by rollers 71, 72. As shown in Fig. 4, the composite strip consists of a cord D housed in a strip E with an intermediate layer of parallel agglutinated threads F. The devices for applying adhesive, drying, and assembling the separate elements and for shaping the composite strip are arranged in a similar manner to that shown in Fig. 1. Assembling and shaping are effected by shaped guide plates and rollers. Specifications 399,368, [Group VII], and 401,136, [Group X], are referred to.

Title: Electrical control system
IPC: H02P7/292
Filed: 1969-07-21
Abstract: 1,223,370. Control of D.C. motors; rectifying. GENERAL ELECTRIC CO. 21 July, 1969 [1 Aug., 1968], No. 36515/69. Headings H2F and H2J. In a cross-fire protection system, a reversible D.C. motor 1 receives power from a transformer secondary winding 2 by way of alternate groups of controllable rectifiers 3a-3c and 4a-4c which are poled in respective positive and negative directions. The groups of rectifiers are associated with negative and positive firing circuits 5, 6. A generator 7 provides a command signal indicative of the desired position of the motor, this signal being compared with a feed. back signal from a device such as a selsyn. The resultant signal is fed to a summer 9 for comparison with the output of a tachometer generator 10, the output signal from the unit 9 being applied to the firing circuits 5, 6. When the output of the generator 7 is positive, a trigger circuit 12 is set to inhibit and permit respectively the operation of the firing circuits 5 and 6. Only the rectifiers 3a-3c are fired under these circumstances. The trigger circuit 12 is re-set when it receives a negative signal from the generator 7, whereby the rectifiers 4a-4c only are then fired. The cross-fire protective arrangement is specially suitable for systems in which the relation between the time of firing of the rectifiers and the power transferred is linearized by advancing the firing angle by a predetermined amount. In such systems the probability of cross-fire is increased at a particular firing angle.

Abstract: 851,756. Autographic registers. LAMSON PARAGON Ltd. Nov. 25, 1958 [Nov. 25, 1957], No. 36687/57. Class 16. In an autographic register, after a form length has been fed, the assembly of stationary webs is arrested and registered by means of a spring- urged finger which normally presses against the assembly and automatically engages in one of a series of feed control apertures in the assembly, and means is provided, when the cover of the register is opened for loading a fresh web assembly, for maintaining the finger away from the assembly to enable the latter to be inserted. The registeris of the kind comprising a locked compartment to receive a record of entries, has a hinged top cover 2a, and the webs are fed by frictionfeed discs 7 which are rotated by a handle and co-operate with top pressure rollers. The discs 7 are mounted on a non-circular shaft 4 which may be driven in two separate phases, for feeding each form length, through gearing and clutch mechanism as described in Specification 840,355, the operating handle being rotated first in one direction, and then in the opposite direction. The control apertures in the web assembly are adapted to be engaged by two fingers 9 on arms 10 which are joined together and pivotable about a shaft 12. The arms 10 are urged upwardly by springs so that an extension pin 14 on each engages a cam track 15 on the face of the adjacent feed disc 7. Lobes 16 in the tracks 15 depress the fingers 9 away from the webs when a new form length is to be fed. When the hinged cover 2a of the register is opened to enable a fresh web assembly to be inserted, the cover depresses the head 20 of an arm 19 to rock a pivoted lever 17, against the action of a spring 21, which depresses a cranked extension 12a of the shaft 12 : the shaft 12 is thus rotated, and stops 22 thereon depress the arms 10 carrying the fingers 9 so that they do not impede the insertion of the new assembly.

Title: Improvements in or relating to electric clock synchronising-systems
IPC: G04C11/04
Filed: 1946-12-19
Abstract: 631,192. Clocks. ZELLWEGER, Ltd. FACTORIES FOR APPARATUS MACHINE USTER, Dec. 19, 1946, No. 37437. Convention date, Dec. 20, 1945. '[Class 139] A system for automatically holding in synchronism secondary clocks connected to alternating current supply mains, by means of control impulses superposed on such mains is characterised in that the impulses are rectified in the clock or clocks to be synchronised, are stored for an interval of time and then delivered to switch means which actuate controlling and correcting mechanism which sets the clock or clocks to the correct time. In each secondary clock, Fig. 1, a synchronous motor 1 rotates, through gearing, the minute and hour hands 2 and 3 frictionally mounted on shafts 6 and 12 respectively. Surrounding the shaft 12 is a sleeve 19 which carries at its top end a wheel 44 which meshes with a pinion 43 on a shaft 42 which carries a cam 38, Fig. 2. Immediately below the cam 38 is a cam 24 continually rotated at four revolutions per minute by the synchronous motor 1. Every hour an electromagnet 31 receives, as disclosed later, an energizing impulse whereupon the pawl 34 is disengaged from a collar 35 on the sleeve 19 which is moved downwardly by a spring 36. An arm 37 on the sleeve 19 thereupon forces a pin 49, carried by the cam 38, into a recess 40 in cam 24 so coupling the cams 24, 38 and their shafts together. The synchronous motor 1 now drives, through gearing, the sleeve 19 which makes one revolution in three minutes. A pawl 41 holds the pin 49 in the recess 40 until tripped by a member 45 carried by the sleeve 19. Just after sleeve 19 starts to rotate it is raised to its upper position by the cooperation of a cam 53 and a tooth of the crown wheel 52. An arm 18 is mounted at the top of the sleeve 19 and has two projections 20 and 21 which during the revolution of the sleeve move the minute and hour hands respectively to the correct position. During this revolution when the projection 21 has moved the hour hand to the correct position the magnet 31 receives a second energizing impulse so that the sleeve 19 may move downwardly for an instant, as before, to disengage the projection 21 from the hour hand 3. The synchronising impulses are transmitted over the mains 4 are filtered by means of the frequency filter 27, 28 rectified by the rectifier 29 and then stored in the condenser 30. The impulses are then sent upon closure of the contacts 26 by the cam 24 or the cam 38 to the electromagnet 31 to effect the above actuation. The cam 24 effects closure of the contacts 26 every five seconds and the cam 38, when coupled to the cam 24, keeps the contacts 26 closed for ten seconds and open for five. To allow a sufficient storage time for the condenser 30 the first impulse every hour is of ten seconds duration and the second impulse is of fifteen seconds duration.

Abstract: 1403082 Testing transmission belts and gears UNIROYAL Inc 15 Aug 1972 [30 Aug 1971] 38052/72 Heading G1S Transmission belts 60, 62, Fig. 7, to be tested are connected to a shaft driven by a belt 90 and motor 14 and also to aligned shafts 32, 38 provided with a torque applier 64 which imparts relative rotation to the shafts 32, 38 in opposite directions. Pre-load tension is applied to the belts by actuating a piston and cylinder 18 to shift the plate 12 mounting the motor 14 along guide rods 48, the plate being held in the desired position by lock nuts 106, 108. The main tension load is applied by hydraulically sliding racks 76, 78 to rotate the gear 70 and shaft 32 in one direction, and by reaction, to rotate the shaft 38 in the other direction, the maximum rotation of each shaft being 90 degrees. The loading on the test assembly is measured directly by a strain gauge torsion bridge 110. In a modification, Fig. 10 (not shown), the driving shaft has a flexible coupling mid-way of its length and a gear-pump replaces the applier 64. In other modifications Figs. 8 and 9 (not shown) the apparatus is altered to test multiple drives. Static studies of the belts can be performed by arranging the belts to carry the pre-load and tension load due to the torque while applied to motionless shafts. The belts and their pulleys may be replaced by inter-engaging gear sets to be tested by rotating shafts 32 and 38 as in the case of belt testing.
