Title: Improvements in or relating to turntables for turning rolling stock or handling vehicles of model railways
IPC: A63H19/34
Filed: 1942-04-22
Abstract: 556,783. Toy turntables. PINDER, T. April 22, 1942, No. 5375. [Class 132 (iii)] In a toy turntable, the weight of a vehicle, such as a locomotive is used to turn or assist in turning the same on the turntable. In Fig. 1, the turntable 1 is secured to a sleeve 2 having a cam surface on its underside for engagement with a fixed pin. When a vehicle runs on to the table from the direction A, it tilts the table to release projection 5 from a stop 8 and the table descends and turns against the action of spring 9 which returns the table to original position after the vehicle has left. In Fig. 3, there is a dog clutch 12 between the table and the sleeve 2, so that after the table has turned itself and the sleeve, leaf spring 13 assists spring 9 to lift the table without turning, and to turn the sleeve back to original position. Devices are described for cutting the current when the rails of an electric railway turntable are not in alignment and for reversing the current when the table tilts under the weight of a vehicle.

Abstract: 496,110. Printing-machines. MANN & CO. (1932), Ltd., G., and HENSE. C. H. Feb. 23, 1937, No. 5449. [Class 100 (ii)] Inking-apparatus.-A-n inking-apparatus for a rotary printing-machine is constructed so as to ensure a complete breaking-down of stiff inks by providing in each set two steel rollers C, E, Fig. 1, 14, 15, Fig. 2, which are constantly driven and are associated with other rollers 2, 3 ; 4, 5, Fig. 1 ; or 4a, 5a, Fig. 2, which are carried in oscillating arms, controlled by cam- and-lever mechanism. The arms bring the rollers 2, 5 alternately into contact with an ink supply roller B, and the rollers 3, 4 alternately into contact with an inking roller D connected by distributing rollers with the plate cylinder P. The rollers 2, 3, 4, 5 are maintained constantly in contact with the rollers C, E, and are moved to neutral positions out of contact with the rollers B, D, each roller remaining in such position for a period corresponding to one or more rotations of the cylinder P. In Fig. 2, the rollers 14, 15 are in continuous contact with rollers 4a, 5a, which receive ink from a roller 24 and transfer it to a roller 25, each roller 4a, 5a, in turn occupying a neutral position in which it acts to break-down the ink in coaction with the rollers 14, 15 respectively. In modified forms of the device shown in Fig. 1, (a) the roller B instead of receiving ink directly from a messenger roller 1, receives it from a roller in contact with a second roller which receives ink from the messenger roller ; (b) the roller B receives ink from two rollers which contact alternately with it and are each supplied from the same roller to which the messenger roller 1 supplies ink. In a modification of the device shown in Fig. 2, four independent sets of rubbing-down rollers are used in place of the two shown in Fig. 2, the second set being arranged to receive ink from the first set so that a double rubbing- down action takes place. Specifications 403,990 and 472,894 are referred to.

Abstract: 762,515. Testing yarns. FARBENFABRIKEN BAYER AKT.-GES. Feb. 25, 1954 [Feb. 28, 1953], No. 5592/54. Classes 120 (3) and 142 (1). [Also in Group XL (b) ] The tithe of a running thread is determined by measuring the absorption of a beam of X-rays. Alternatively the X-rays may be used to calibrate an arrangement in which B-rays are used for measurement. In the arrangement of Fig. 1 (not shown) the X-rays are passed through a rectangular slit above which runs the thread to be gauged, the slit being of increasing area in the direction of travel of the X-rays so as to resemble a funnel: Above the thread is situated a radiation counter tube and below the X-ray source is a comparison tube. The outputs of the two tubes are combined in a differential amplifier and used to mark a continuous paper record. In the arrangement of Fig. 2 wherein a number of threads are to be gauged separately, the X-ray tube and differential counter are carried on the lower limb of a U-shaped member 9 embracing the threads to be gauged while the measuring tube is mounted in the upper limb. The U-shaped member is advanced to gauge a particular thread by means of a lead-screw 11 driven through a magnetic clutch until a feeler 16 engages a thread, thus closing a contact that disconnects the magnetic clutch and causing a solenoid 17 to lower a guiding member 15 to guide the thread. The measurement continues for a predetermined period until a timing member advances the gauge to the next thread.

Title: Improvements in or relating to the insulation of high frequency electric conductors
IPC: H01B3/18
Filed: 1937-02-26
Abstract: Insulation for electric conductors consists of native cellulosic material esterified up to or beyond the diacyl stage to form an ester or esters of a carboxylic acid or acids having from 2 to 5 carbon atoms whilst retaining sufficient strength to permit its lapping on the conductor.  Esterification may be carried out by immersing the cellulosic material in yarn form in a bath containing toluene, petrol, or other inert diluent, acetic acid, acetic anhydride and zinc chloride, until the material has a combined acetic acid content of 55 per cent.  The yarn is then hydro-extracted and washed.  In another process, cotton yarn, purified by bowking and bleaching, is washed, dried and then immersed in acetic acid, after which the yarn is transferred to an acetylating bath containing benzene, petrol, or other inert diluent, acetic acid anhydride, glacial acetic acid, and anhydrous zinc chloride.  The yarn is then washed, hydro-extracted and dried.  Specifications 372,312, 395,737, 417,929, 447,313, and 489,928, [all in Group XXXVI], are referred to.

Title: Improvements in or relating to injection moulding machines
IPC: B29C45/03
Filed: 1949-03-05
Abstract: 662,957. Injection-moulding machines. DAVIDSON, R., and BUTTERWORTH, C. March 6, 1950 [March 5, 1949; Sept. 2, 1949], Nos. 6058/49 and.22738/49. Class 87(ii) The injection cylinder 3 is movable longitudinally within a casing 1, being provided with wheels 5 which run in channels 6a in members 6 removably secured in the side walls of the casing. When the machine is idle and the injection ram 7 is in the retracted position shown, a spring 64 tends to move the cylinder towards the mould, but the cylinder is held away from the mould by headed rods 12. The rods 12 pass loosely through holes 11a in a plate 11 secured to the ram, and are secured at their left-hand ends to the cylinder. When the ram moves to the left at the beginning of its injection stroke, the spring 64 urges the cylinder to the left and seats the nozzle 4 in the mould. As the ram continues its stroke the plate 11 leaves the heads 11b on the rods and slides along the rods. When the ram returns to the right the plate 11 picks up the rods again and returns the cylinder to the position shown. The mould 57 is held by wedgeshaped jaws 41 slidable between guides on diverging faces 39a of a recess in a block 39. The block is adjustably secured by screws 40 in a plate 38 joined by bolts 36 to a plate 1b which forms the end of casing 1. The block is vertically adjusted by means of a screw 52. The jaws 41 are urged to the left by springs 56, but may be moved to the right, to open them so that they may receive the mould, by means of a handle 44a. This handle is secured to a lever 44 pivoted at 45 and carrying a plate 48 to which are fixed push rods 47. By rocking the lever counterclockwise the jaws may be pushed from the Fig. 3 position to the Fig. 6 position to receive the mould. A spring 50 returns the lever, rods, &c. The mould is positioned within the jaws by abutments 41b on the latter and by a screw 58, Fig. 1, (not shown). When the injection cylinder is in the rearward position shown, moulding material is fed thereinto by manual rotation of a member 25 mounted in the lower part of a hopper 19 secured to the top of casing 1. Louvres 17 are formed in the casing. The ram is reciprocated manually by rack-and-pinion mechanism 8, 9. The cylinder has electric heaters 28 and a torpedo 67.
