Title: Improved digital data recording and reproducing system
IPC: G11B20/18
Filed: 1963-08-29
Abstract: 1,017,627. Digital data-storage. AMPEX CORPORATION. Aug. 29, 1963 [Oct. 4, 1962], No. 34277/63. Heading G4C. Identical digital data is recorded in at least two channels in complementary codes and reproduced therefrom with self-clocking. A sequence of binary digits is supplied by a source in an NRZ format, a high signal level representing " 1 " and a low level " 0." With the aid of mark generators fed with clock pulses, the bit sequence is converted into the NRZ formats in which a change (positive or negative) of signal level always indicates " 1 " (two generators) and " 0 " (one generator). The signals are recorded in these forms on magnetic tape in three channels in parallel. During read-out, each channel feeds an individual peak detector, via amplifiers, the peak detectors feeding a clock pulse generator which responds to the first pulse received (only) during a given bit interval to generate a single clock pulse. This pulse is delayed so as to be in the approximate centre of the bit interval in view of the likelihood of tape-skew. These clock pulses drive a flywheel pulse producer, to stabilize interpulse interval and replace missing pulses. The outputs from the peak detectors are also sampled at AND-gates controlled by the pulses from the flywheel device. The outputs of the AND-gates pass to converters which convert the signals back to the original NRZ format (see above). In the absence of errors, the outputs from the converters will thus be identical. These outputs pass to majority rule logic and error detection circuits. Gating circuitry may also be provided for indicating the channel in which the error occurs. A fourth tape channel repeating one channel may be provided. It is mentioned that the data may alternatively be recorded on a drum or disc or by electrostatic, optical or thermoplastic techniques.

Title: Improved method of running-in friction brakes
IPC: B60T17/22
Filed: 1953-12-10
Abstract: 731,788. Brake drums. DAIMLER-BENZ AKT.-GES. Dec. 10, 1953 [Dec. 15, 1952], No. 34446/53. Class 103 (1). In a method of running-in friction brakes, the part of the brake which is equipped with the brake lining is assembled together with a coacting member which has a roughened surface co-operating with the lining so that the brake is run-in after assembly with this rough coacting member. The rough coacting member can either be removed after running-in and then be replaced by the normal coacting member, or it may be used after running-in for permanent operation in the respective brake. When applied to the front wheel of a motor vehicle, the brake drum 1 has been roughened by sandblasting, before assembly, on its brake surface 2. During operation on the road, the brake lining 4 mounted on the brake shoes 3 will adapt itself to the shape of the brake drum, as the result of wear against the rough surface of such drum. The previously sand-blasted brake drum may continue to be used for permanent operation in the brake as the brake drum surface simultaneously becomes increasingly smooth during the running-in process.

Abstract: 923,157. Timber substitutes. U. GOTTSCHALK. Sept. 26, 1961 [Sept. 30, 1960], No. 34481/61. Class 22. Boards from wood chips or fibres provided with a binding agent are produced by arranging two layers of chips or fibres provided with a binding agent between press platens and arranging a layer capable of absorbing steam and moisture and without any active binding agent between the two layers. In a preferred modification chips from the station (1) are dried in a drier (2) from which part is passed through by path a to be mixed with binding agent at station (3) and then distributed into two layers (4) between the heated press platens (7) meanwhile the other part of the chips which are dried further are mixed, if desired, with colouring, moistureresisting, fire-proofing and termite-resisting additives in the station (10) and arranged as a layer (5) between the layers (4). The boards are then compressed by either applying full pressure immediately or by gradually increasing the pressure. Stop means may be used to control the thickness of the boards. When the pressure is released, the boards (4<SP>1</SP>) are brushed free from chips by brushes (8<SP>1</SP>, 8<SP>11</SP>) and planed by rollers (9<SP>1</SP>, 9<SP>11</SP>), The partides resulting from these operations and the loose particles from the layer (5) are then returned by path d to station (3) to be mixed with binding agent. The layer (5) however can be made of any material and covered with a layer of a dusting material or of fabric, or other means to prevent adhesion between the layers. Specified additives referred to above are paraffin and mineral wax for moisture resistance, ammonium phosphate or boric acid for flame resistance and pentachlorphenol to combat termites.
