Title: Improvements in or relating to magnetic reading and recording
Inventor: SHARP JOHN JOSHUA
IPC: G11B20/14
Filed: 1956-02-06
Abstract: 851,520. Electric digital-data-storage apparatus. INTERNATIONAL COMPUTERS & TABULATORS Ltd. Jan. 8, 1957 [Feb. 6, 1956], No. 3616/56. Class 106 (1). Apparatus for reading binary signals recorded magnetically (e.g. on drum disc or tape) by either a single or double reversal of magnetic state, respectively, comprises gating means controlled by output signals from a reading head to generate a single output signal only in response to a double reversal of magnetic state in a discrete area of the record. A reading head 13 feeds signals via an amplifier 14, transformer 15 and full-wave rectifiers 16, 17, to a clipping stage 18, a single pulse for each binary zero and a double pulse for each binary one. These signals are fed to an AND gate 21 by a direct connection and also via a delay circuit comprising a differentiator 19 and a trigger circuit 20. The delay is such that the first pulse of a double pulse representing binary one will pass through the delay circuit and open the gate 21 at the right time to allow the second pulse through via the direct connection. A single (binary zero) pulse fails to pass through to the utilization device 22. A more detailed version of this circuit and an arrangement for recording binary signals of the type referred to, are also shown and described.

Title: Improvements in method and apparatus for treating continuous lengths of textile fabric
IPC: D06C7/02
Filed: 1956-02-13
Abstract: 800,049. Shrinking fabrics. SAMCOE HOLDING CORPORATION. Feb. 13, 1956 [Feb. 24, 1955], No. 4463/56. Class 42 (1). [Also in Group XIII] A textile fabric 16, Fig. 1, is advanced through a treating zone by tossing a number of successive increments of the fabric, or alternatively the whole of the fabric, forwards and backwards in the plane of travel of the fabric. In the preferred embodiment, a continuous length of woven or tubular knitted fabric having a moisture content of not more than 40 per cent by weight is shrunk by passing it through a housing 10 divided by a partition 11 to form a closed path for air circulated by a series of fans 14 which may be heated by units 13. Moisturesaturated air may be continuously replaced by fresh air in the fan chamber. A roll 17 having a variable speed drive feeds the fabric on to fabric tossing means 18 which toss the fabric alternately forwards and backwards, the forward toss being greater than the backward toss so as to feed the fabric through the housing on to a conveyer 20 of an open mesh material running at a sufficiently slow speed to prevent tension in the fabric The means 18 consists of elements 24 which are mounted on shafts 25 connected together by chain drives 26 and oscillated from a crank 33 connected by a rod 34 to a crank 35 rotated through a gear reducer 37 and a chain drive 41 by an electric motor 43.

Patent GB-498563-A (GB)
Title: A method for the common and selective remote control of alarm apparatus, which are connected to already existing lines, more especially telephone lines, radiating from a central station
IPC: G08B27/00
Filed: 1938-02-16
Abstract: 498,563. Electric signalling systems. LANDIS & GYR AKT.-GES. Feb. 16, 1938, No. 4786. Convention date, Feb. 25, 1937. [Class 40 (i)] [Also in Group XXXIX] An alarm system comprises a transmitting station I connected by line j1 to a central station II of a network, which may be a telephone network, over which access is given to sub-stations III having audible or visual alarms S1, a sub-station being selected by a central station switch in response to impulses from the transmitting station which also transmits a control current to switch over the sub-station line from the normal central equipment to the alarm transmitting line j1 and to operate the sub-station alarm. The alarm is operated continuously or intermittently for a time predetermined by the transmitter. A certain impulse train causes all sub-station lines to be switched over to the alarm line. When impulse transmitter I is moved off normal, relay O pulls up, followed by P, and holds itself over cancel key B3 and contacts of a time switch R. Relay P connects line jl to the impulsing and control circuit, and G at the central station repeats the impulses to relay S2 which interacts with S3 to step the selector K. If an intermittent alarm is desired, key B1 is thrown to operate relays D and E which lock up, start the timing devices R, T, energize relay H and disconnect the continuous alarm key B2. Timing device T intermittently connects to line j1 one terminal of A.C. source E3 the other terminal of which is connected up by relay H. Relay W1 at the central station responds and on the first pulse V pulls up, locks over off-normal contacts k of the selector and operates the selected relay Y which switches the substation line over to the alarm line. Subsequent A.C. pulses operate sub-station relay W2 which switches in the alarm Sl. After a predetermined time, timing device R operates its contacts whereupon relays D, E, O and P fall back and the alarm ceases. Relay G at the central station falls back, the selector is stepped to normal, and the central station circuits restore. The timing devices R and T remain operated until R opens contact r1 whereupon relay H also falls back. If continuous alarm key B2 is pressed, relays D and F pull up instead of D and E, and the operations are the same as before except that the contact of T which applies intermittent A.C. is shunted by a contact of F applying continuous A.C. For a general alarm, digit 1 is dialled and X pulls up to release switching relays U whereby all the lines are connected to the alarm line.
