Title: Defrosting controlling circuit means for electric refrigerators
IPC: F25D21/08
Filed: 1968-12-23
Abstract: 1,203,168. Defrosting control systems. MATSUSHITA ELECTRONICS CORP. 23 Dec., 1968 [28 Dec., 1967], No. 61092/68. Heading H2H. [Also in Divisions H3 and G1] In a refrigerator, defrosting is controlled by a circuit which includes heating means and a solid state semi-conductor switching element 4 which is switched on by operation of a pair of transistors to initiate a defrosting operation, the cycle being terminated when the temperature in the freezer reaches a predetermined value as detected by a thermistor 8. As shown, when the refrigerator is operating normally, transistor 5 is conductive, transistor 6 is non- conductive and SCR 4 is also non-conductive. A switch 13 is closed to initiate a defrosting operation, this causing transistor 5 to become non-conductive and transistor 6 to become conductive, thus triggering SCR 4. As the temperature in the freezer rises, the resistance of thermistor 8 decreases until eventually transistor 5 again becomes conductive and transistor 6 becomes non-conductive. In alternatives, the SCR may be replaced by a bidirectional semi-conductor element (18) and transistor 6 by a PNP transistor (19) such that when transistor 5 is conductive transistor (19) is conductive and vice versa. The thermistor 8 may be connected to the base of transistor 5, and the rectifying diode 11 may be positioned before the voltage divider 9, 10 on the circuit. The heating means may be a heater or a relay adapted to actuate a valve through which hot gas is to be circulated.
Patent GB-762449-A (GB)
Abstract: 762,449. Interrupters. GENERAL MOTORS CORPORATION. Dec. 3, 1954 [Dec. 23, 1953], No. 35057/54. Class 38(5) In a combined ignition contact breaker and distributer a plate 28, on which the contacts 78 are mounted, is journalled by means of an upturned part 32 on a fixed sleeve 30 which forms the bearing for the driving shaft 26 so that the contact breaker, its actuating cam 34 and the bearing are substantially in the same plane and bending movements on the shaft are minimized. Orientation of the plate 28 with respect to the cam in order to change the timing is effected by means of a device operated by engine suction acting through an aperture 92 on a diaphragm 94 and causing a rod 96 to move to the right (Fig. 5) and rotate the plate 28 by engaging a pole near its edge. Movement of rod 96 is limited by an aperture 108 in a member 106 which is fixed in an adjustable cross-bar 110. The cam is adjusted relative to the shaft 26 in accordance with speed by centrifugal weights 40 and 42 which are pivotably mounted on a plate 36 which is rigidly attached to the cam. At speed the weights are thrown out and by bearing on a plate 38 fixed to the shaft 26 cause relative movement between parts 36 and 38 and advance the cam with respect to the shaft. Buttons of nylon 29 or similar hard wearing material support the plate 28. A rotor 48 above the centrifugal mechanism carries a contact member which progressively passes near to distributer terminals 56 in the cap 58. The cap is located in a recess in the base and secured by spring clips 70. Hand adjustment of the contacts relative to the cam is effected by a screw 80 accessible through a slidable window in the cap, Fig. 7 (not shown).

Title: Flexible multi-columnar cellular gas/liquid contact apparatus
IPC: C02F3/10
Filed: 1978-08-23
Abstract: A flexible gas/liquid contact structure 14 consists of stacked horizontal partition walls 34 formed from pairs of sheets of non-woven fabric material, such as felt heat- jointed by plastic coatings on their inner surfaces and disposed in vertically-spaced parallel arrangement and sealed at their sides by accordion- folded sheets 28 of flexible collapsible material. The paired sheets contain ports 52 which are offset relatively to one another in successive sheets. The paired fabric sheets and their plastic- coated inner surfaces are provided with openings to form cells 54 with which the ports communicate, these openings being so arranged that a multi-columned structure of parallel cellular formation results, with independent zigzag paths between top and bottom of each cellular column. The structure is preferably suspended from an external framework, the suspension causing the laminated partition walls to separate into parallel columns of laterally-interfitting vertically-staggered cells. <IMAGE>

Title: Apparatus for mounting a vehicle drive unit
IPC: B60K5/10
Filed: 1978-10-05
Abstract: A vehicle drive unit is supported in a vehicle frame by mountings which each comprise a primary member (11) connected to the drive unit, a secondary member (13) and a resilient member (12) between the primary and secondary members. The drive unit is moved to its end position in the vehicle frame on rollers (14) which roll on tracks (16) of intermediate parts (15), connected to the vehicle frame. Shortly before reaching the end position, the rollers (14), are relieved of load since the tracks (16) have downwardly directed ramps (18) at this location. The rollers (14) are thus lifted from the ramps (18) and the secondary members (13) of the resilient mountings are connected with the vehicle frame. <IMAGE>

Title: Improvements in and Relating to the Production of P-Nitrophenols
IPC: C07C205/26
Filed: 1978-11-21
Abstract: The invention relates to a process for the production of p-nitrophenols, such as p-nitrophenol or p-nitro-m- cresol, by oxidation of the corresponding p-nitrosophenols. The p-nitrosophenol is brought in contact with an acid reaction medium in which at least a small part of it is soluble, and which contains nitrate- or nitrite-ions or a nitrogen oxide, preferably NO2(N2O4) or NO. The medium may be, for example, nitric acid to which may be added a miscible organic solvent (such as acetonitrile) to secure dissolution of part of the nitrosophenol. By "aerating" the medium with oxygen or a mixture of oxygen and an inert gas, the nitrosophenol is at a moderate temperature and pressure (preferably 15-35 DEG C and ambient pressure (quickly and practically completely converted into the corresponding nitrophenol which is separated in very pure form.

Title: Image-reproduction apparatus
IPC: H04N1/60
Filed: 1980-05-22
Abstract: This invention is concerned with a colour scanner for the graphic arts of the kind in which three uncorrected colour-component analogue signals from the scanner are converted into digital form (20) and are applied to the inputs of a three-dimensional look-up table (24) or read-only memory in which are stored corresponding colour-corrected signal values for the three colours and, if desired, for black. In this invention, individual one- dimensional colour-component look- up tables (22) are interposed between the analogue-digital converters (20) and the three-dimensional look-up table (24) to provide signals representative of print density. The functions performed by the one- dimensional tables may include logarithmic conversion of the input signals, for example. Preferably, further individual one-dimensional look-up tables (28) are inserted between the outputs of the three- dimensional table (24) and a digital- analogue converter (30) preceding an output scanner (34, 36). <IMAGE>

Title: Improvements in data transfer control in a peripheral controller
IPC: G06F5/10
Filed: 1978-06-16
Abstract: In a peripheral controller of a data processing system having a plurality of system units electrically coupled to a common communication bus 13 for asynchronous intercommunication, for dynamically tracking data byte transfers an array of counters 77 responsive to both hardware and firmware control are connected in a manner to form a serial control data path. Prior to a data transfer, a serial data stream including an offset range count, a range count and a main memory address is shifted through the counters 77 under firmware control. During a data transfer, the firmware enables the hardware control to increment the memory address and decrement the range count to accommodate the higher data transfer rates characteristic of hardware control. <IMAGE>
