Title: Magnetic memory systems
IPC: G11B5/725
Filed: 1972-04-24
Abstract: 1395041 Magnetic discs BURROUGHS CORP 24 April 1972 [6 May 1971] 18874/72 Heading G5R A disc record 10 comprises a base 14, a magnetic layer 15, and a wax layer 16, the wax having a melting point which is slightly above the general operating temperature of the disc; if, therefore, a pneumatically supported head (11, Fig. 1, not shown), should unexpectedly drop on to the record during operation, the local temperature will rise, some of the wax will melt, and the head will "skate" on a liquid wax film. No permanent damage will thus be caused, and when the local temperature drops the liquid re-solidifies. Various waxes and thicknesses thereof are specified. The layer 16 may be formed by spraying on to layer 15 a solution of the appropriate wax in a volatile liquid.

Title: Improvements relating to brake mechanism for vehicles
IPC: B60T11/04
Filed: 1925-07-24
Abstract: 257,393. Clark, D'A. M., (Bendix Brake Co.). July 24, 1925. BLocks and shoes acting on drums; force-transmitting mechanism; compensating for wear.-Relates to operating mechanism for steering wheel brakes of the kind in which a friction member when applied to a drum is free to move circumferentially so as to anchor at either end according to the direction of rotation of the drum. As shown, the friction member comprises a pair of shoes 20, 22 hinged together by a free pivot 24 and adapted to anchor at either end against bolts 32, 34 passing through slots 36 in the shoes. The bolts are secured to the backing plate 18 and to a strengthening piece 38. The shoes are expanded by toggle links 26 engaged by a lever 40 mounted on the bolt 34 and straddling one of the shoes. The surface of the lever 40 engage by the toggle 26 is coaxial with the drum when the shoes are applied, to permit the circumferential movement of the shoes. The lever is actuated by a second lever 44 mounted on the vehicle axle and having a ball end which engages the lever 40 at a point which lies in the axis of the steering pivot when the brake is applied, or, if it is desired to relieve the braking pressure on the outer wheel in making a turn, slightly on the wheel side of that axis. A cable directly connected to the lever 40 may be substituted for the lever 44. The shoes are held by springs 30 against adjustable eccentric stops 28 in the release position. Specifications 254,478 and 254,658 are referred to.

Title: Looms
IPC: D03D47/27
Filed: 1978-05-12
Abstract: In the weaving machine, weft threads (31) are each inserted by means of an airjet from a weft unit (25, 26) simultaneously from outside towards the centre into two weaving tracks (12, 12a) arranged next to one another. The insertion capacity can thereby be increased in comparison with an alternating weft insertion from the middle of the two tracks. If the weaving width is relatively large, there are no misgivings that the two simultaneous air-insertion jets directed from outside towards the centre could interfere with one another in the central aisle (32) between the two weaving tracks (12, 12a) and impede the formation of a respective selvedge (36) along the middle aisle (32). <IMAGE>

Title: Improvements in or relating to processes and apparatus for the oxidation of inorganicsubstances
IPC: C01G21/02
Filed: 1936-07-13
Abstract: <PICT:0474267/III/1> In the production of oxides and suboxides of lead, the initial material is cooled before and/or while being comminuted in air when in a solid brittle condition to a state of such extremely fine division as to be air-borne, and is then exposed to a mixture of air and ozone which may also be cooled.  The temperature of the material to be oxidized or of the oxidizing mixture or both may be below 60 DEG  C.  The rate of oxidation may be controlled by varying the proportions of the oxidizing mixture, and its degree by controlling the temperature or concentration of the ozonized atmosphere, the temperature of the material, its degree of fineness, or the duration of the treatment.  Cold air may be admitted at any stage of the process to cool the material or prevent its further oxidation, and oxidation may be effected in more than one stage if desired.  The product may be bleached by ultra-violet rays. In carrying out the process, lead or lead suboxide may be fed to an attrition mill 3 surrounded by a cooling jacket 4, and the comminuted product be drawn through a conduit 7 to the oxidizing chamber 10 by a fan 8.  Material insufficiently finely divided leaves the conduit 7 at 9 and is returned to the mill.  Air is supplied to an ozonizer 14 from a pipe 15 surrounded by a cooling jacket 16 and the ozone-air mixture formed is drawn into the oxidizing chamber which is surrounded by a cooling jacket 11.  The oxidized powder is drawn through the fan casing to the delivery pipe 19.  According to the Provisional Specification, any inorganic substance and, in particular, metals and alloys, may be subjected to oxidation by means of ozone.

[Also in Division G3] In an arrangement for measuring a number of variables, the variables are converted into electrical parameters such as resistance, and the parameters, e.g. the resistances r 1 . . . .r n , are connected in succession into an arm of a single measuring bridge, the other arms of which are resistors R 1 , R 2 , R 3 , by a switching system including transistors T 1 ...T n  which are rendered conducting or non-conducting by pulses from a control unit C. In the embodiment of Fig. 1, the transistors T 1  are normally conducting and the application of a pulse to one of them renders it non-conducting, so that the related resistor is then included in the bridge. In an alternative arrangement the transistors are connected directly into the bridge in parallel and must be switched so as to conduct to include the related resistor in the bridge Fig. 2 (not shown). The output from the bridge is applied via amplifier A and transformer T across a Zener diode Z. If the output amplitude exceeds the unblocking voltage of this, a voltage pulse across the load resistor R c  is obtained. The arrangement is used in a temperature control system where it is necessary to scan a number of temperature measuring resistors r 1 .. r n  and provide heating when the temperature falls below a preset level.
