In use, the coated surface of the transfer sheet is placed in contact with one surface of a master copy sheet, and on typing or writing on the other surface of the master a substantially colourless reverse image is produced on the first surface of the master. This surface is then brought into contact successively with sheets of copy paper moistened with a copying fluid in the presence of an electron-accepting substance so as to give a visible reproduction on each of the copy sheets. The electron accepting substance, which may be present in the copying fluid or in the paper, may be an organic or inorganic acid, acid mineral, or acid-treated coating. The copying fluid may comprise ethanol with or without water, benzyl alcohol, or ethylene glycol.

Title: Clipping level control circuit
IPC: G06V30/162
Filed: 1959-11-24
Abstract: 899,617. Valve clipping circuits. INTERNATIONAL BUSINESS MACHINES CORPORATION. Nov. 24, 1959 [Nov. 24, 1958], No. 39927/59. Class 40(6). [Also in Group XIX] To compensate for variations of background colour in an automatic character reading apparatus, the signals derived from scanning the character are clipped at a level set by the signals following and in advance thereof. The character is sensed in motion by a C.R.T. which makes a series of vertical lines each consisting of a number of short horizontal scans. A photo-multiplier 15 picks up the signals and after amplification they are applied to a delay line 21 having a number of taps 29 and a central tap 39. The data signals are recovered at the tap 39 and are applied to a triode 45, the cathode voltage of which is set by a cathode follower 61. This is controlled by the signals from the taps 29 which are connected through summing resistors 35 to line 37 connected to the grid of cathode follower 61. Triode 45 acts as the clipping circuit, signals on line 43 which exceed the output, from the cathode follower 61 produce an output on terminal 47. Upper and lower values of the clipping level are set by adjustable wipers 53 and 55 on a potentiometer 57, which are connected through oppositely poled diodes 49, 51 to the line 37. The delay line may be composed of a number of L-C stages or it may be an acoustic delay line. Alternatively a rotating magnetic drum may be used.

Title: Hydro-Pneumatic Suspension Systems for Vehicles.
Inventor: PEIFFER JOACHIM
IPC: B60G17/04
Filed: 1968-08-21
Abstract: 1,194,276. Hydro-pneumatic vehicle suspension. V. LANGEN, [trading as LANGEN & CO.]. 21 Aug., 1968, No. 40024/68. Heading B7D. [Also in Division F2] In a hydro-pneumatic vehicle suspension wherein a wheel-supporting member (axle) 1 pneumatically supports a vehicle body by two or more gas chambers 7, 9, deflection of the wheel axle 1 beyond each end of a predetermined range of movement operates a stop valve 10 to cut off one 9 (or more) of the gas chambers, simultaneously or in succession, to increase the load/deflection characteristic of the pneumatic spring. As shown in Fig. 1 the axle 1 is supported by an hydraulic displacer unit communicating with the hydraulic fluid chamber 6 of a hydropneumatic accumulator 4 the gas chamber 7 of which communicates via a pipe 8 with a gas reservoir 9 through a spool-type stop valve 10. The valve 10 is mechanically operable by a lost-motion linkage 7 which follows movement of the axle 1 to effect closing of pipe 8 on deflections beyond predetermined limits. In an alternative arrangement the reservoir 9 is replaced by an accumulator similar to 4 and the hydraulic fluid chambers of the two accumulators are linked via a pipe incorporating the stop valve. Fig. 3 shows an arrangement wherein two air chambers 31 and 32 are provided in a common casing 28 separated by a rigid wall 30 having a central aperture 36 sealable by a valve 37. The valve stem 38 extends through the chamber 30 to terminate in a piston 39 movable in a cylinder 40 against a spring 41 by hydraulic fluid ducted into the cylinder chamber 42 via a pipe 43 and a stop valve 44. The valve 44 is supported between springs 47, 48, connected respectively with the axle 1 and vehicle body, to be moved, on excessive deflection of the axle in either direction, to disconnect the pipe 43 from exhaust and to connect it to an hydraulic fluid pump 46 whereby to raise piston 39 and valve 37 to close the aperture 36. In this arrangement the casing 26 encloses an hydraulic fluid chamber 34 separated from the gas chamber 31 by a flexible diaphragm 33. In both arrangements a level control valve 12 is incorporated.

Classes 120(1) and 120(3) Short fibres, such as wool fibres having an average length of from 4 to 12 centimetres, are prepared for spinning by a first drafting stage wherein the fibres are gripped in a first position, fed forward to a second position not more than 6 centimetres in advance of the first position and then combed forwardly from the second position at a speed not less than three times the feeding speed. It is stated that by employing such a process carding machines need not be used. Scoured wool from a hopper is placed on a conveyer feeding to a "converter" gill box in which the front and back ratches (i.e. distances from roller nips to the nearest faller pins) may be 5 cm., the back draft 6, and the front draft 2. The sliver produced passes to second and third "converters" similar to the first but with a back draft of 3 and a front draft of 4. A burr crushing mechanism may be included at any suitable stage. After a back-washing operation the material passes through two normal gill boxes and thence to a Noble comb.

The remainder of the leg D and foot F is also knitted with woollen and elastic yarns and the ankle portion E may have an additional laid-in elastic yarn. A patterned effect may be obtained, particularly over the portion B, by feeding the ordinary yarn to the plain needles and the elastic yarn to the rib needles of a superimposed coaxial cylinder machine the elastic yarn being tensioned to float clear of the plain needles. For the remainder of the leg D the elastic yarn may be knitted on one set of needles at one feeder for one course and on the other set of needles for the next course, the ordinary yarn being fed to the set of needles not supplied with elastic yarn. Further bands of laid-in yarn may be provided as required and the portion C may be knitted entirely of elastic yarn and may include a zone of both woollen and elastic knitted yarns together with laid-in elastic yarn.
