Abstract: 1457373 Pneumatic braking systems KNORRBREMSE GmbH 19 Nov 1974 [24 Nov 1973] 50146/74 Heading F2F A flow dependent monitoring device for monitoring the flow of pressure medium in the main line of a braking system such as that of a railway vehicle which includes a brake valve for controlling pressure in the main line, a source of pressure and a throttle 6 in the main line or a feed line thereto comprises a device 9 for monitoring differences in pressures prevailing upstream and downstream of the throttle 6 and arranged to respond to a pressure differential in excess of a predetermined minimum, a control line extending from a supply of electric current to a shut-off device controlled by the monitor 9 in response to change in relative pressures upstream and downstream of the throttle, a first device 19 to indicate a brake-release condition when the valve is moved to a release position, thereby creating a flow of pressure medium in the main line with consequent generation of pressure differential across the throttle, a second device 18 to indicate a hazard situation when a hazard generated flow of pressure medium occurs in the main line such as to create a pressure differential across the throttle, a double-throw switch 15 arranged to connect either the first or the second device to the control line, the shut-off device being arranged to permit flow of current only when the pressure differential across the throttle in excess of the predetermined minimum is detected. A drivers valve 1 is connected via a solenoid valve 3 and line 4 to a source of pressure air (not shown) and to the main air line 5 which contains the throttle 6 and has a pilot circuit which is connected by a pneumatic line 20 to a differential pressure switch 21 having contacts 24 connected in a control line 29 from a current source 14 to device 19, indicating brake release, and to a relay coil 30 which when excited operates the switch 15 and contacts 28 in a line 31 connected in series with contacts 32 and monitoring device 18 which monitors hazard-generated pressure air streams in the main air line. Connected in parallel are a relay coil 33 operating contacts 32 and the coil 34 of solenoid valve 3. Only when venting occurs in consequence of an emergency at main air line 5 is the device 18 excited and replenishment feeding of pressure air into line 5 automatically interrupted until the driver has shifted valve 1 to a braking position. If however the driver operates valve 1 to release brakes then only device 19 (indicating brake release) is excited. Devices 18, 19 may provide audible or visual warnings.

Filed: 1963-12-23
Abstract: 989,870. Seaming non-metallic sheet material; laminates. L. J. VILUTIS, and M. J. VILUTIS, [trading as VILUTIS & CO.]. Dec. 23, 1963 [Dec. 31, 1962 (3)], No. 50635/63. Headings B5K and B5N. Edge portions 10, 11 of two multilayer thermoplastic films 12, 13 are bonded together by inserting the one edge portion 10 between the layers 15, 17 of the other edge portion and applying energy in some suitable form to bond the interleaved surfaces together. As shown, the edge portions may constitute the outer edges of a single sheet of multi-layer film in which case bonding produces a tubular article having a multilayer wall. The layers of the thermoplastic film may have the same or differing dielectric loss factors. Where at least one of the layers has a high dielectric loss factor dielectric heating may be employed for the bonding of this layer and the heating effect may be sufficient also to cause bonding of an adjacent layer having a low loss factor. Pressure is usually employed to exclude trapped air from the seam area and to ensure intimate connection at the bond. A layer of printing may lie between the layers of the thermoplastic film material. Ultrasonic vibrations may be employed to provide the heating effect necessary for seaming. Materials referred to as having a high dielectric loss factor include the normally crystalline copolymers of vinylidene chloride and vinyl chloride, polyvinyl chloride, polyvinyl acetate, cellulose acetate, cellulose acetate butyrate, rubber hydrochloride, and polyamide. Materials having a low dielectric loss factor include polyethylene, polystyrene and polytetrafluoroethylene. Apparatus is described (Fig. 5, not shown) in which a single sheet of two-ply material is fed continuously to means which fold the sheet, interleave the edges and seal the interleaved portion by means of dielectric heating to form a continuous tubular product.

Title: Store comprising drivable domains
IPC: G11C19/08
Filed: 1974-11-22
Abstract: 1484905 Magnetic domain stores PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 22 Nov 1974 [26 Nov 1973 25 March 1974] 50777/74 Heading H3B A domain storage device includes a plurality of domain storage plates P1-P7 having propagation paths controlled by diverging switches so spaced and oriented as to be uniquely addressable by corresponding sequences (i.e. reversals) of a common rotary magnetic propagation field. As shown, each plate includes a domain generator and storage path and uses individual or a common readout device SA and domain burster. A permanent magnet bias field is provided and a control unit CTR receives control data at K1 relating to, e.g. read/write instructions to drive orthogonal Helmholtz coils, only one pair C1, C2 of which is shown, to establish the rotating field. A typical layout Fig. 1A shows a generator A0 which produces one bubble for each rotation period, switches A1, A2 which may divert such bubbles to bursters A4, A5 to read-in a binary zero, or to a storage path A7 and a final burster A6 via a readout device A3. The storage arrangement may have major and minor loops linked by diverging transfer switches such as in Fig. 4A. Counterclockwise field rotation propagates bubbles upwardly T01-T06 on a major loop and clockwise around a minor loop T10, T09, T08, Y02, I07, Y03, T13, T12 &c. If the field is reversed for 7/4 rotation periods, a bubble at position 4 on Y01 (nomenclature Y014) follows Y01, I04, T07 and a return to normal counterclockwise rotation introduces the bubble to Y02 for inclusion in the minor loop. Similarly, a bubble which was at Y033 would be transferred over T14, I10, Y04 to the major loop at Y044. To make the selection unique in different plates, the path length between switches differs, the switches are differently oriented and/or are differently constructed as only to respond to a characteric sequence of reversals of different numbers of periods. Numerous layouts involving major and minor loops formed of T, I and Y bars are described in Figs. 2-10 (not shown) allowing, e.g. parallel read-in/out of word bits at different levels into a main loop, and incorporating a loop containing a bubble splitter of chevron or T, I and Y bars associated with further switches for diverting the split bubbles to a burster or further readout loop. The plates may be coplanar and consist of vapour deposited permalloy on a lamination giving a total access time of 6À5 ms.
