Patent GB-329933-A (GB)
Title: Improvements in or relating to matrix setting and type-line casting machines
IPC: B41B7/18
Filed: 1929-09-23
Abstract: 329,933. Wade, H., (Typograph Ges.). Sept. 23, 1920. Type bar - making machines; driving - mechanism; distributing matrices. - In machines having matrices guided in a cycle on wires, and having a vertically movable carriage for conveying the matrix line to the distributing-wires, on to which the matrices are transferred by a slide, the operating-mechanism comprises two racks, which are coupled together during the raising of the carriage, and are then uncoupled, one rack only continuing to move, in order to operate the matrixslide. The distributor-carriage 3, Fig. 4, and the horizontally moving matrix-slide 4 are operated from a continuously rotating shaft 6, Fig. 3, which drives a disc 7 carrying a stop 8, which serves to rock a double lever 10. The lever 10 raises a slide 12, which is situated under a stop 13 secured to a rack 16. To the upper end of the rack 16 a second rack 17 is normally coupled by a catch 45 engaging a pin 47. The slight rise of the racks 16, 17 effected by the lever 10 lifts a rod 19, Fig. 12, from the path of a lever 21, and causes a coupling 23 to be thrown into gear. A pinion 27 gearing with the rack 16 is thereby caused to rotate, so that the racks 16. 17 are raised farther. The rack 17 is connected to the distributor-carriage 3 by gearing 28, 29, Fig. 4, a rack 30, and a chain 31, the rack 30 acting as a balance-weight. The carriage is supported at the top of its travel by a catch 40, and the racks 16, 17 are then uncoupled by disengagement of the catch 45 by a projection on the machine frame. The rack 17 then remains stationary, but the rack 16 continues to rise and operates the matrix-slide 4. This is effected by engagement of a projection on the rack with a depending spring- pressed rod 51, Fig. 4, which is connected by lever mechanism 52, 53, 54 with the matrix-slide. In its movement, the slide 4 disengages the catch 40, but the carriage 3 remains supported by a spring pin 62, which is released by the slide. In the highest position of the rack 16, a stop 66 at its lower end throws out the coupling 23, which is then locked by the descent of the rod 19. The spring-pressed rod 51 then pushes down the rack 16, which is again coupled to the rack 17 by the catch 45. The matrix-slide 4, on its return, pushes in the pin 62, and allows the carriage 3 to fall. To permit of repeated casting of the same line, the carriage is locked in its lower position by a hand-operated bolt. A spring connection between the rack 16 and the latch 45 allows the rack 16 to be lifted by the lever 10, although the rack 17 is locked against movement.

Title: Improvements in or relating to dynamo-electric machines
IPC: H02K47/16
Filed: 1921-10-31
Abstract: 170,863. Somajni, G. Oct. 30, 1920, [Convention date]. R o t a r y transformers; windings.-In a system employing dynamo - electric machines for obtaining a number of lower voltages from a continuous-current supply circuit, four separate commutator windings, a, b, c, d, Fig. 2, located on one or two dynamo-electric machines are connected in series across the supply circuit V. In the case in which the four windings with their commutators are included in one machine as shown in Fig. 1, each slot contains sections of all the windings; the commutators have the same number of segments, and, to obtain good commutation, the segments are arranged and connected to the winding sections in such a way that the sections lying in the same slots are connected to segments lying in the same axial plane. Fig. 3 shows the arrangement of conductors in a slot. Low-voltage circuits are connected to any two points between the separate armature windings a, b, c, d, Fig. 2. By using different pairs of terminals A, B, C, D, E, a uniform voltage gradient is obtained and the system is particularly adapted for the speed-control of traction motors.

Filed: 1921-10-31
Abstract: 196,639. Rich, L. J. Oct. 31, 1921. Alternating current systems.-Means are provided for opening and closing the transmission circuit at a predetermined part of the alternating current cycle. The actual opening and closing of the transmission circuit A, B are effected by a slip ring 1, making one revolution per cycle, and adapted to connect or disconnect two brushes 2, 3. The signals are initiated by a key K. A cam 6 controls contacts 9, 10. Contact 9 closes just after disconnection of brushes 2, 3 and opens just before the brushes are connected again. Contact 10 closes just after the connection of the brushes and opens just before they are disconnected. A cam 5 operates contacts 7, 8, these contacts being opened briefly, contact 7 when contact 9 is closed, and contact 8 when contact 10 is closed. Cams 5, 6 make one revolution per cycle. Electromagnet 14 controls contacts 15, 16, and electromagnet 11 controls contacts 12, 13, the circuit connections being as shown. Normally, key K and contacts 12, 13, 15, 16 are open. When key K is closed, nothing further occurs until contact 9 becomes closed, whereupon magnet 14 closes contacts 15, 16, the former in circuit A, B. Slip ring 1 then closes the circuit A, B at the required instant. Contact 10 then closes, causing magnet 11 to close its contacts 12, 13. Circuit A, B is now closed through contacts 15, 12 irrespective of the position of the slip ring, and remains so closed as long as key K is closed. When key K is opened, the subsequent opening of contact 8 de-energizes magnet 11 and opens contacts 12, 13, and opening of contact 7 de-energizes magnet 14, opening contacts 15, 16.

Patent GB-1096455-A (GB)
Title: Improvements relating to the manufacture of decorative sheet material
Inventor: SAUL WALTER
IPC: D06C23/00
Filed: 1964-07-14
Abstract: A method of making a decorative sheet material comprises applying an adhesive composition to parts of a textile - fabric carrier sheet, attaching flock electrostatically to said parts of the carrier sheet, and making at least one additional application each of adhesive and flock, in that order, to further parts of the carrier sheet said additional adhesive being applied on the surface of the carrier sheet opposite to that on which all the flock is applied and passing through said carrier sheet, each successive application of flock being of different colour and/or of different fibre length from flock of any preceding application, until the pattern is complete.  The first applications of adhesive and flock may be on the same face or opposite faces of the carrier-sheet.  The design for the first flock colour may be printed on to the carrier by a rotating printing roller carrying adhesive from a reservoir or by using a screen or block method. Concurrently, an opaque registration line is printed at the edge of the carrier fabric and in front of the first pattern which enables subsequent printed adhesive to be printed in register with the first pattern by means of a photo-electric cell device. With a transparent adhesive, the registration line can be printed on prior to adhesive printing.  The carrier is then flocked electrostatically using electric potentials of say 20 kilovolts per inch distance between the electrodes, before passing to a heating zone where the adhesive is dried and/or cured and a flock recovery zone where excess flock is removed.  The carrier is then passed to the second adhesive printing station where correct registration of the second pattern with the first is achieved by the photo-electric cell device, to a second flocking station followed by drying and flock-removal zones and subsequent flocking stations where additional flock colours may be applied.  After a final heat treatment the finished material may be edge trimmed and cooled and wound up.  In the example a woven fabric is printed with an acrylic latex adhesive and red nylon flock applied, followed by another adhesive print and white nylon flock. The products are said to be useful as carpeting, wall coverings or other surface coverings.
