Abstract: 740,699. Knitting-machines. NEBEL, M. Nov. 3, 1952 [Nov. 2, 1951], No. 27573/52. Class 74 (2). To facilitate making the fabric shown in Fig. 1 of Specification 507,660, web holders P are provided, having a yarn receiving ledge pa, a raised ledge ps and a throat pb at a level lower than the ledge pa. The web holders are cut away below the ledge pa so that a thread guide SF for an unknitted weft yarn can be introduced to feed its yarn to the rear side of the needles. Long and short shanked needles N', N<SP>2</SP> are arranged alternately and are operated by cam tracks disposed at different levels, and in operation yarn to be knitted by one set of needles N<SP>1</SP> is laid upon the ledges pa of partly advanced web holders disposed above the needles N<SP>2</SP>, and is knitted by the needles N<SP>1</SP>; subsequently the web holders are further advanced (Fig. 3), so that the loops of yarn they hold are received in the throats pb, and the needles N <SP>2</SP> are raised to take the loops from the web holders, which are retracted to withdraw them from the loops. Sinker loops held by the web holders disposed above the needles N<SP>1</SP> are taken similarly from those web holders and knitted. The high ledges ps serve to separate the sinker loops 3, Fig. 4, about to be transferred, from the old loops 4 about to be cast off the receiving needles. To ensure opening of the latches the needles are given a short raising and lowering movement. The knitting cams may be adjustable vertically in slidable members.

Title: Improvements in or relating to automatically regulated ac/dc converters
IPC: G05F1/33
Filed: 1955-09-30
Abstract: 790,515. Automatic voltage control systems. BENDIX AVIATION CORPORATION. Sept. 30, 1955 [Oct. 15, 1954], No. 27929/55. Class 38 (4). In a system for the automatic control of the output voltage of a metal rectifier of the kind in which the output of an auxiliary, saturable reactor controlled rectifier is connected in series with the main rectifier, the auxiliary rectifier is energized by the ripple current in the reservoir condenser of the main rectifier so as to operate at a higher frequency than the main supply and so reduce the time lag of the reactor. A main 3- phase rectifier 1 supplies D.C. output terminals 6, 7 from a 3-phase A.C. input 4. The output is smoothed by choke 17 and capacitors 20, 21, 22. A transformer 26 in series with the reservoir condenser 20 supplies an auxiliary rectifier 31, 32 at ripple frequency. The output of the rectifier 31, 32, smoothed at 23, 24, 33, is connected across the resistor 5 in series with the output of the main rectifier 1 so as to boost (or buck, according to the sense chosen for the control circuit) its output. A voltage-sensitive bridge consisting of gas tubes 37, 51 and linear resistors 35, 36 is connected to the output terminals 6, 7 and controls a self-saturating transductor 29, 30 controlling the auxiliary rectifier 31, 32. Chokes 34, 40 and capacitors 42, 43 eliminate ripple fed back from the control windings of the transductor to the bridge.

Title: Modular data handling systems
IPC: G06F11/32
Filed: 1975-07-04
Abstract: 1509783 Data storage systems INTERNATIONAL BUSINESS MACHINES CORP 4 July 1975 [19 Sept 1974] 28184/75 Heading G4A Modular data handling apparatus comprising a system which has the capability to circumvent its own faults includes, for assisting in error diagnosis, early warning sensing means connected to modules for sensing degradation in the operation of a module, failure sensing means connected to modules for sensing failure in the operation of a module, means for scanning the failure sensing means in response to a failed operation, and means for logging the addresses of modules indicated as having failed when so scanned. As disclosed, each of a number of storage units includes a read/write unit and a read/write controller with a power unit for each, each power unit having a plurality of early warning sensing means and a plurality of failure sensing means. Each early warning sensing means detects when the output (or input) of a replaceable module goes out of a tolerance of Œ4%. Each failure sensing means detects when the output of a replaceable module goes out of a tolerance of Œ25% concurrently with the input of the module not going out of a tolerance of Œ25%. The early warning sensing means, if any of them detect out of tolerance, set a POT bit of a status byte of the storage unit, this byte being sent (in any event) to a storage system processor at the end of the read or write operation. In addition, each early warning sensing means, if its output persists for more than a certain time, sets a respective latch to energize a respective light-emitting diode, until the latch is reset manually. The storage system processor can use a clock-driven counter to scan failure sensing means (using address decoders at the storage units) to send a pulse to the processor for each detected failure, this pulse temporarily stopping the scan so the processor can take note of the address (the count). Sequence of processor operations.-When a read/write operation fails, the status byte is stored, and recovery is tried (viz. retry read or write, and may involve use of error correcting codes). If recovery is successful, then if the POT bit is not set the recovery action and status byte are logged, whereas if the POT bit is set, the scan is performed and in the event of any failures being detected their addresses are logged whereas otherwise a power transient failure (transient on outside power lines) is logged. On the other hand, if recovery is not successful, the scan is performed, and the processor deduces that failure is in the power unit or elsewhere in the storage unit according as failure is detected in the scan or not, the storage unit being logged as not available in either case, and the failed module address being logged in the former case, the failed storage unit being electronically removed from the system with re-issue of the operation to another unit, a service call being logged. All the above monitoring equipment is powered by the power units of the processor.

Filed: 1933-10-14
Abstract: 424,020. Moving signs. ALLTREE, A., Rydal Dene, Pilling Lane, Preesall, near Fleetwood, Lancashire. Oct. 14, 1933, No. 28421. [Class 3 (i)] One or more endless bands to which are pasted, clipped, or otherwise secured advertising slips, cards, panels, &c., are controlled intermittently by an electrically driven or controlled clock. The band may pass round four horizontal or vertical rollers 6, one of which drives and another of which is mounted on a spring-retracted pair of pivoted levers to tension the band. Fig. 3 shows a motor 20 rotating through reduction gearing 23, of the pinion or worm-wheel type, a disc 25 on which is eccentrically mounted a pitman 26 which oscillates a disc 27. A pawl 28 on the disc 27 engages a ratchet 39 either on a pinion 30 geared to the roller 6 or on the roller 6 itself. Adjustment of dimensions to ensure the pawl 28 having a travel just less than two teeth gives a longer dwell to the roller 6 than the time taken in shifting it. A chain &c. on the band meshing with teeth 6<a> on the roller 6 ensures register of the display panels at the viewing window or windows in the clock casing. The mechanism 20, 23 may be located in the space enclosed by the four rollers, or when two pairs of rollers each carrying an endless band are employed, may be mounted above the rollers. The device for switching the motor 20 into and out of action comprises a disc 19, Fig. 11, rotated once a day by the clock mechanism 3, the disc having a plurality of circumferential holes into any of which two fingers 38, 39 can be inserted and fixed. The fingers alternately contact with and snap over a spring-controlled and double-triggered disc 40 which through a pin 40<c> inserts and removes a switch contact 43<a> into and from circuit contacts 44, 45, thus setting the motor 20 into and out of use for extended periods. The display panels &c. may be on two bands or drums rotating in opposite directions, a differential gearing being then employed to connect the roller or drum shafts. A lamp may be disposed above the clock casing and be switched on and off by fingers or contacts on the disc 19 or on a similar disc.
