Title: Filtering process
IPC: B01D46/26
Filed: 1970-10-27
Abstract: 1314080 Gas filtering JOHNS-MANVILLE CORP 27 Oct 1970 [27 Oct 1969] 50904/70 Heading BIT Submicron particles of liquid or solid are filtered from a gaseous effluent by passing it through a web of bonded or unbonded glass fibres of diameter up to 10 microns at a velocity of at least 300 feet per minute and at a pressure drop of at least 8 inches of water measured across the clean web. Fig. 1 illustrates a suitable filter wherein the web is fed progressively from roll 28 to roll 38 round the perforate shell of drum 10, being separated therefrom by endless screen 32. Filtered gas is drawn from one end of the drum. Alternatively the web may be fed across a flat support plate. Or the web is formed on a support by feeeding the fibres into the incoming gas. Fixed bonded fibre webs may be used after coating the upstream surfaces with asbestos fibres fed into the gas in the manner of a filter aid. Densities, thicknesses and fibre sizes of suitable webs are exemplified.

Abstract: 1,160,877. Cutting by fusion. HANCOCK & CO. (ENGS.) Ltd. 10 Nov., 1967 [15 Nov., 1966], No. 51154/66. Heading B3V. An oxygen jet cutting machine for cutting the web of a beam to castellated shape, comprises a carriage 11 having two pairs of wheels such as 59, 60 on vertical axes spaced apart to engage one flange 64 of the beam, a pair of rollers 53, 58 adapted to rest on the upper edges of the beam flanges, and a slide 21 carrying the cutting burner 15 movable transversely of the carriage and driven by an endless member such as a chain 40 trained around four wheels 37 whose axes define a rectangle parallel to the plane of the beam web. One of the chain wheels 37, Fig. 4 (not shown) is driven through an electromagnetic clutch (28) and bevel gearing (32), (33) by an A.C. motor (27), whose speed is controlled by a siliconcontrolled rectifier. The chain wheel drive is also connected to a horizontal shaft 49 which drives through gearing 50, 51 a parallel shaft 52 carrying the roller 53. Both rollers 53, 58 are also inter-connected by a drive chain 55. Slide 21 runs along guide rods 41 and carries guides 43, 44 for a slide member 48 engaging a pin 46 attached to the chain 40.

Abstract: 1276907 Rolling LANDIS MACHINE CO 20 Oct 1969 [31 Oct 1968] 51347/69 Heading B3M [Also in Division B8] The invention relates to a feed mechanism for a work-forming apparatus, particularly a gear rolling apparatus as disclosed in U.K. Specification 1,205,662, in which a support member 24 is movable to carry a workpiece W from a loading and unloading station to a forming station, the feed mechanism comprising a workpiece feed shoot 44, an outlet shoot 46 and a shuttle 42 driven by a member 76 which supports a workpiece in the shuttle while moving it from the feed shoot to the support member thereby preventing it from falling into outlet shoot 46. On removing the workpiece from support member 24 the member 76 is withdrawn by a pinion 90 operating on a rack on its upper surface leaving the workpiece unsupported and so able to enter outlet shoot 46. This is achieved by a lost motion connection between a pin 96 and a groove 98. A blade 114 associated with the shuttle 42 prevents more than one workpiece entering the shuttle at a time.

Title: Control arrangement in an electronic watch
IPC: G04G9/00
Filed: 1975-12-16
Abstract: 1528178 Electronic timepieces EBAUCHES SA 16 Dec 1975 [6 Jan 1975] 51398/75 Heading G3T An electronic timepiece is arranged to selectively display either one of two different types of information data on the same display, the nature of the displayed information being distinguished by causing the display of one type to appear continuous and that of the other to perceivably blink, or alternatively the colour of the emitted light (in the case of LED display) may be changed according to the type displayed. The timepiece Fig. 1 includes an oscillatorfrequency divider circuit 1 for producing coded time of day signals and a chronograph circuit 2 for producing coded elapsed time signals. Normally, with a switch 7 open, a selection gate circuit 3 detailed Fig. 2 (not shown) will pass the coded time of day signals A to be decoded at 4 and a gate circuit or "interface" 5 detailed in Fig. 3 (not shown) will pass the decoded signals to cause activation of appropriate segments of appropriate 7-segment digit devices in an LED display. When the switch 7 is closed the chronograph circuit is activated and a signal SC causes the selection circuit 3 to pass coded elapsed time signals to be decoded at 4. The signal SC also opens a gate (15) of the "interface" gate circuit (Fig. 3) to pass pulse trains m, n, at 8 Hz and 16 Hz respectively and derived from the chronograph circuit 2, to the inputs of NAND gates (8) to (14) to modulate signals from the decoder which are being passed to appropriate segments of the display digits. Thereby these digits are caused perceivably blink. Fig. 5 (not shown) illustrates a gate circuit or interface whereby, in dependence upon the logic state of signal SC, current is directed to one electrode of a respective LED causing it to emit light of one colour or to another electrode thereof causing it to emit light of a different colour.

Title: Device for measuring the load of the pressure rollers of a drawing mechanism
IPC: G01L5/00
Filed: 1964-12-18
Abstract: In order to measure the pressure exerted by the supporting and loading arm centrally upon twin pressure rollers in a drafting device, a rod is inserted in the arm instead of the rollers and is supported at each side of the arm on fixed parts, the support on one side being effected through a resilient element, the deflection of which is measured by an instrument.  The rod is supported at both sides of the arm on the bottom roller, but it may also be supported on the measuring-side by an apron guide.  On the side opposite the measuring-side, the rod bears on the lower roll through a bracket or roller with an interchangeable shim on the measuring-side, the rod carries an arm resiliently connected to a member, or connected to a member which is itself resilient, which member bears on a lower roll through rollers or a curved foot; relative movement between the arm and the resilient member is read off on a gauge.  The connection between the arm and the resilient member is adjustable.
