Filed: 1965-06-25
Abstract: 1,048,515. Record/playback switching. INTERNATIONAL STANDARD ELECTRIC CORPORATION. June 25, 1965 [June 30, 1964], No. 27003/65. Heading G5R. Diodes D1, D2 are fed with a control voltage and the amplifier acts in the record mode; when not so fed, in the playback mode. On record, the input impedance is the record gain control L which is effectively earthed by D1 and the lower portion C2, R2-R4 of the feedback network is effectively shorted to earth by D2. On playback, D1 is a much higher impedance than L, which is thus effectively non-operative as a gain control and the feedback network operates normally. Gain on playback is controlled independently of L by a volume control associated with the power amplifier. The unrectified output of the bias/erase supply may be used as the control voltage, provided its frequency is outside the pass-band of the amplifier.

Title: Method for the filtration of a fluid and filtering installation for carrying out this method
IPC: B01D25/12
Filed: 1965-06-28
Abstract: 1,110,753. Filtering apparatus. DOUCET S.A. 28 June, 1965 [1 July, 1964], No. 27282/65. Headings BID and B1T. A fluid to be filtered is delivered to the upstream side of a filtering wall 48, which is thereby maintained in vibration to detach impurities therefrom, and a proportion only of the incoming fluid passes through the wall, the remainder sweeping across the upstream face to remove detached impurities from the filter housing. The filter wall may be cloth or metal gauze, and the vibration is effected by narrow apertures 57 through which the incoming fluid is directed approximately parallel to the filtering surface. In the embodiment of Figs. 8-10, the filtering element 48 is of tubular, octagonalsection form and apertures 57 are circumferentially spaced about the upper and lower ends of the element. The incoming fluid is delivered from pipe 58 to conduit 46, 47 and the filtered fluid leaves by conduit 61. At circumferentially spaced locations intermediate of apertures 57, the annular space 50 communicates with outlets (59), 60 for the fluid used to sweep the upstream surfaces (Fig. 10 not shown). In addition an air vent 62 is supplied whereby the filter housing may be drained, prior to directing jets of cleaning fluid from nozzles (52) carried by a central tube 51 (Fig. 10 not shown) onto the downstream side of the filter element 48 whereby the element is backwashed. The said cleaning fluid may be heated, supplied under pressure, and may contain solvents or acid. Supply of the cleaning fluid through conduit 56 causes the tube 51 to move axially upwards in cylinder 54, the rate of movement being limited by outlet 63 above the upper closed end of the tube 51, this movement allowing the jets of clean fluid to cover the whole area of the filter element 48. Alternatively the tube 51 could be rotated. In an alternative embodiment (Figs. 2-7 not shown) the filter is constructed in the manner of a filter press, with flat filtering elements (15) being clamped between two different forms of annular elements (10), (11) arranged alternately. Elements (10), (11), (15) all have co-operating through holes, which, when the filter is assembled, form axially extending ducts whereby the fluid to be filtered is supplied to the interior of elements (10), part of it sweeping over the elements (15) and being removed from said interiors, while the remainder passing through the elements (15) and is withdrawn from the interiors of elements (11). The filtrate receiving elements (11) are supplied with air inlets for expelling the fluid prior to cleaning, and with centrally mounted jets (33) for delivering the cleaning fluid. The cleaning fluid may be liquid or gaseous or foam. and the cleaning action may be initiated at regular intervals by a timer or in response to an increase in pressure drop across the filter. The jets of cleaning fluid may cause the filter elements to vibrate, in a similar manner to the fluid being filtered.

Title: An improved method of stacking and apparatus for receiving sheet material delivered from printing, photocopying and like machines
IPC: B65H31/00
Filed: 1958-08-26
Abstract: 925,871. Delivering sheets. OZALID CO. Ltd., and J. G. B. HALDEN. Aug. 26, 1959 [Aug. 26, 1958], No. 27293/58. Class 100 (1). Sheet receivers.-A delivery conveyer 2 of a printing, photocopying or like machine terminates adjacent to an end wall 1 of the machine for delivering sheets into a tray 3. The tray 3, which may be of sheet metal, has an upwardly convex base and side walls 6, 7, a strip 9 being attached to the edge 10 of the tray adjacent to the end of the conveyer 2. The tray is hinged to the wall 1 at 8 and is adjustably supported by a pair of stays 12 each of which is pivoted at opposite ends to brackets 11, 13 on the tray 3 and wall 1 respectively. Each stay 12 consists of two members 14, 15 in telescoping relation with each other, the combined length of which can be adjusted by means of a screw 16 engaging a slot 17 in the member 15. When sheets 18 having little or no rigidity are to be delivered from the conveyer 2 the stays 12 are adjusted to their maximum length so as to raise the end of the tray 3 remote from the conveyer to its greatest height. As the sheet emerges from the conveyer it droops and the leading edge engages the base of the tray 3 at a position where the base is rising away from the wall 1. The leading edge of the sheet then slides back until it reaches the edge 10 of the tray, the sheet being progressively inverted as it is fed from the conveyer. When comparatively rigid sheets are to be delivered the stays 12 are adjusted to their shortest length so that the base of the tray over substantially the whole of its length is inclined downwards away from the wall 1. The leading edge of a rigid sheet delivered to the tray in this position engages the base of the tray at a position where it slopes downwards away from the wall 1, and slides forwards until it engages the wall 7 of the tray.

Abstract: 956,603. Moulding rubber boots. SUPERGA S.p.A. July 28, 1961 [Aug. 12, 1960], No. 27530/61. Heading B5A. A method of making a rubber boot comprises applying the constituent parts 21, 22, 23 of the boot to a last 1 which is then partially exhausted through seat 2 to remove air trapped between the parts before a number of lasted boots are grouped together for vulcanization. The boot assembly is placed on a conveyer system, last 1 being exhausted for a limited time only. In the construction shown, the conveyer system comprises a guide rail on which runs trolleys which are adapted to form the vacuum link between last 1 and member 16, this being part of a flexible pipe 15. The latter forms part of a spider comprising a central hollow column 10 attached to a vacuum device, a rotating head 12, rigid arms 11 connected at their inner radial ends to the flexible pipes 15, and arms 13. Arms 11 form the hollow links between pipes 15 and head 12. When member 16 is connected to a trolley, arm 13 is forced, against its spring 19, to trigger switch 17 and allows the appropriate pipe, trolley and boot assembly to be exhausted, the connection being maintained by atmospheric pressure. After a limited time pipe 15 is disconnected from the trolley automatically by the interruption of an electrical circuit thus discontinuing the exhaust process. The boot then passes on the conveyer system to an autoclave for vulcanization.
