Title: Improved process of and apparatus for printing covering materials, particularly for use on walls and the like
IPC: B41F19/00
Filed: 1927-09-15
Abstract: 277,683. Akt.-Ges. f³r Wasserdichte Stoffe Filmos Oftringen. Sept. 16, 1926, [Convention date]. Printing processes. - Paper, leather, textile fabric, or other sheet material for covering walls, book-covers, cardboard articles, &c. is printed by means of a smooth roller on which colour in the form of a relief pattern is taken up from a second smooth roller closely adjacent to but out of contact with the first roller and supplied with colour of a suitable consistency. The web 21, Fig. 1, is drawn from a roll 22 by a spiked roller 19 and passes in contact with the lower roller 7 of a pair of smooth rollers 7, 11 positively driven and spaced apart to a variable extent by adjusting screws 12. Colour passes from the container 14 between the two rollers and assumes the form of relief patterns on the rollers, such as ribs b, Fig. 2, projecting from a ground coating a. By varying the distance apart of the rollers and the consistency of the colour, various patterns may be produced. The ribs b, either alone or with the ground a, are transferred to the web 21 and by suitably adjusting the pressure different effects on the web are produced. The pattern may also be varied by rotating the rollers in opposite directions, or at different speeds or by axially displacing one of the rollers during its rotation. The printed web may be calendered. A second web may be printed by means of the roller 11.

Title: Improvements in selectively responsive electric thermal switches particularly for remote control
IPC: G08C19/22
Filed: 1932-09-01
Abstract: 398,341. Thermal switches. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Rich, T. A. ; 1061, Glenwood Boulevard, Schenectady, New York, U.S.A.) Sept. 1, 1932, No. 24410. Convention date, Sept. 1, 1931. [Class 38 (v).] A thermal switch adapted to be operated from a distance comprises an L-shaped bracket 4 on which is insulatedly mounted a bimetallic strip 6 carrying a contact 1 strongly biased towards engagement with a contact 2 on the bracket 4. A heating unit 10 is connected between the strip 6 and bracket 4. A second bimetallic strip 12 is insulatedly mounted on the bracket 4 and a heating unit 15 is connected between the strip 12 and bracket 4. The strip 12 when cold is biased to the left and rests against the end of a resilient blade 16 insulated from the strip 6 but carrying a contact engageable with a contact on the strip 6. Assuming the parts to be in the position shown in Fig. 2, circuit from main supply 5, 7 to a consuming device 3 is completed through bracket 4 and contacts 1, 2. If now a long current impulse is applied by means of relay 11, circuit is made through bolt 8, strip 6, heater 10, bracket 4, and contacts 1, 2. After a while the bias of the strip 6 is overcome and the circuit is broken at 1, 2 and the consuming device is cut out. As the strip 6 cools it bends down but is prevented from making circuit by the end of strip 12 whose end engages under member 16 making connection between strip 12 and strip 6 thus connecting heater 15 in parallel with heater 10, and the circuit remains open. If now. a short impulse is supplied through relay 11 both heaters are energized but strip 6 requires a long period of heating before it overcomes its inherent closing bias, but strip 12 moves at once and releases member 16 allowing circuit to close. Heater 15 is now cut out and parts are in position, shown in Fig. 2. Thus a short impulse closes the circuit and a long impulse opens it. The current impulses are supplied to relay 11 by means of superimposed high frequency currents on the main conductors 5, 7 through a tuned circuit 18, 19. One end of the tuned winding of relay 11 is connected to a point 20 on the inductance 19 while the other end is connected through rectifiers 22, 23 of the copper oxide type to points on either side of point 20. In this way unidirectional impulses are supplied to relay 11.

Title: Improvements in and relating to apparatus for converting electric currents
IPC: H02M7/54
Filed: 1921-09-14
Abstract: 169,694. Coninck, M. de. Sept. 30, 1920, [Convention date]. Commutator switching - arrangements.- In an apparatus for converting alternating current into direct current or vice versa in which commutator segments are connected to resistance elements, magnetic means are provided for limiting the amplitude of the harmonics of the alternating current. The arrangement shown in Fig. 1 comprises a rotating commutator C with brushes F1, F1<SP>1 >&c. connected to the polyphase leads I, I<1> &c., the segments of the commutator being connected to a resistance winding R, which rotates with the commutator and is connected at two or more points P, P<1> to slip rings B, B<1> whose brushes are connected to the direct current leads. The resistance is given decreasing values when approaching the direct current taps, and the commutator segments near these taps may be short-circuited or replaced by a larger segment. The number of taps may be increased by connecting them in parallel, the number of brushes for each phase of the polyphase current being correspondingly increased and connected in parallel. The third harmonic current and its multiples are limited by means of a reactance coil A, Fig. 3, having a single closed magnetic circuit and windings A' - - A' in series with the phases of alternating current. The higher harmonic currents may be limited by providing sufficient leakage reactance in the transformer or other apparatus connected to the alternating-current side of the converter. The resistance R may be wound around insulating-pegs G, G<1> carried by a metallic wheel E, Fig. 5, secured to the commutator shaft. Highvoltage direct current may be obtained by mounting several converters C1 - - C3 on the same shaft and connecting them in series as shown in Fig. 7, in which only the connections and brushes for the phase I are shown. When converting direct current into polyphase current, the converter may be used for driving synchronous motors at variable speeds by varying its speed of rotation. In order to obtain approximate equality of the counter E.M.F. of the motor and the voltage at the brushes of the converter at different speeds, the excitation or grouping of the windings of the motor may be varied, or resistances may be inserted on the direct-current side. Synchronous motors may also be driven at varying speeds from a polyphase supply by the use of two converters, the first of which rectifies the supply, while the second converts the direct current thus obtained into alternating current of varying frequency.

In a wheeled vehicle having two parts to be fastened together in fixed relative positions by a catch, the catch comprises a hook fixed to one part of the vehicle and a co-operating hasp pivotably mounted on the other part of the vehicle, the arrangement being such that to fasten the two parts of the vehicle together, the hook and hasp are brought together and the hasp is swung over the hook into a position in which it engages the convex side of the hook. In the construction shown in Fig. 3 one of the parts is a handle 3 and the other part is a body 1. The hook 5 is secured to the body and the hasp 7 is a member having a U shaped portion with two arms 8 which are apertured to receive an arm of the handle 3 to pivot the hasp to the handle. A tongue 9 extends from the base of the U shaped portion to act as a handle by which the hasp is manipulated. The hasp is held in position on the handle by a cap 12 bolted to the handle between the arms 8. The base of the hasp is formed with a small protrusion 11 which exerts a wedging action on the convex side of the hook when the arm of the handle is in the hook and the hasp is swung to the fastening position. In Fig. 5 which shows an alternative use of the catch the two parts are the body 1 and chassis 2 of the perambulator. The body 1 is located in position on the chassis 2 by four rubber blocks 25 of inverted U shape each of which fits over a side member 14 of the chassis; these blocks also act as feet when the body is removed from the chassis. Two catches are used and the hook of each is attached to a transverse member 15 of the frame and each hasp which is identical with that of the previous construction is pivoted on a pin 22 which spans the arms of a bracket 23 of inverted U shape which is fixed to the body 1. When the hasp is engaged with the hook it urges the hook upwardly and consequently urges the corresponding side member 14 into its rubber blocks.
