Title: Improvements in and relating to methods of making insulators
IPC: B28B1/26
Filed: 1925-05-20
Abstract: 256,723. British Thomson-Houston Co., Ltd., (General Electric Co.). May 20, 1925. Casting insulators; casting-apparatus. - Link - type insulators are made from plastic material such as liquid porcelain clay by casting the bodv of the insulator about a separately formed tubular core. Liquid clay is poured into a U-shaped mould 3, Fig. 1, and allowed to settle until a tubular core 4 with the required wall thickness is formed, the surplus slip being then poured away. The core 4 after setting is then placed in a two part mould having a flat part 5, Fig. 3, a shaped part 6 and a gate 9 serving as a reservoir and sufficient liquid clay is put into the mould to form the body 7 of the insulator. By permeation into the core the two parts of the insulator become virtually an integral structure. Drying may be accelerated by the natural or forced circulation of air through the tubular core or retarded by clay plugs 11 at the ends of the core. The insulator is completed by forming an aperture 15, Fig. 5, with shaped ends 16 in its centre and cutting off the ends of the core 4 and splaying the openings 12 thereto.

Abstract: 1500522 Laminates CIBA-GEIGY AG 1 April 1975 [1 April 1974] 13225/75 Heading B5N [Also in Division C3] Laminates are prepared using polymers which contain s-triazine rings obtained by reacting a cyanamide of a secondary amine s-triazine of the formula wherein B and D independently of each other are -O-, -S-, -NH-, -NR-, or a direct bond, R is an alkyl, aryl or heterocyclic group, X and A independently of each other are -O-, -S-, -NH-, -NR- or a direct bond, Q is an organic radical, e.g. arylene, alkylene and/or a heterocyclic group, y = 0, 1, 2, 3 or 4, a = 1, 2 or 3, b = 0, 1, or 2, c = 0, 1 or 2 and a + b + c = 3, with an organic compound of formula HX-Q-(AH) y  wherein X, A, Q, and y are as defined above, except that X and A are not both direct bonds. When b + c is 1 or 2 the triazine compound may be homopolymerized. The polymerization is effected by heatingat 50‹ to 350‹ C. in a solvent or in the molten state. The -CN- group of the first compound reacts with a group HX or HA of the second compound to form a link and a group -C(NH)- which reacts with another -CN group. In examples tris-(N)-cyanoanilino)-s-triazine is reacted with 4,4<SP>1</SP>-methylenedianiline, the product is dissolved in methyl ethyl ketone and the solution used to impregnate glass cloth from which laminates are prepared with heat and pressure.

Abstract: 1353185 Semi-conductor devices LICENTIA PATENT-VERWALTUNGS GmbH 5 May 1971 [5 May 1970] 13241/71 Heading H1K A method of manufacturing a semi-conductor device, which includes forming openings in an insulating layer 2 on a semi-conductor body 1 using a photosensitive layer as an etching mask is characterized by the application of a metal layer 5 of aluminium, gold or titanium between the insulating and photosensitive layers. In a diode embodiment a silicon body 1 including a diffused region 4 has an insulating layer 2, e.g. of silicon dioxide, formed thereon followed by the metal layer 5. Following the photolithographic etching step which produces an opening to the body an electrode layer 8 is deposited over the layer 5 and the exposed body surface. The layer 8 may be of aluminium, gold, titanium, chromium or platinum. The layers 8 and 5 are then etched to the desired electrode configuration as shown. A further layer of a getter or passivation material may also be used between the insulating layer 2 and the metal layer 5. The getter layer may be of doped silicon oxide silicon nitride, aluminium oxide or oxides or nitrides of other elements. In a further embodiment a transistor structure may be produced.

Title: Improvements in liquid pumps with distributors
IPC: F02M59/00
Filed: 1951-06-08
Abstract: 685,980. Fuel-injection pumps. BOSCH GES., R. June 8, 1951 [June 9, 1950], No. 13594/51. Class 102 (i) [Also in Group XXIX] In a fuel-injection pump, a single plunger 6, fitted with the normal by-pass control edge, is combined with a rotary and reciprocating distributor valve 10. The valve has saw-tooth projections 11a, 11b at each end that co-operate with saw-tooth projections 12, 13 formed on stationary members 14, 15 fitted at each end of the valve housing. During the reciprocation of the valve 10, engagement of the projections result in the valve being rotated so that a port 17 registers with each of the outlet ports 28 leading to the engine cylinders in turn. In the construction shown in Fig. 3 a rod 20 passes through the valve and a collar 19 is urged into contact with the valve by a spring 25; the rod is loaded by a spring 22. The valve is reciprocated by contact of the piston 6 with the rod 20 and during the delivery stroke the fuel is delivered past the projections 11a, 12 and port 16 to the interior of the valve. In the construction shown in Fig. 9, the valve 10 is attached to the stem 20a that forms part of the lift valve 35 that is the normal delivery valve of the pump. To ensure that the valve 10 registers with the correct cylinder to agree with the particular lobe of the cam that is actuating the piston, a slide valve 56 is actuated by a second cam 49 and the valve 10 has a slot 52 and the arrangement is such that if the connection is to the incorrect cylinder then the delivery of the pump passes through passages 55 and 53, slot 52, passage 54, groove 59 in valve 56, passages 61, 62 to the pump inlet so that no delivery takes place. If the timing is correct then this flow is obstructed by either valve 56 or 10. In an alternative arrangement a mechanical lock is provided to prevent valve 10 from rotating until the correct timing is restored. The projections 11b slightly uncover the delivery passages 28 when the valve is in its lowest position to equalise the pressure in these passages.

A fabric laying-up machine of the type in which fabric 1 is drawn from a roll or lap and laid on a table by delivery rollers on a carriage traversing the table is characterized in that tension is removed from the fabric 1 during laying on the table by passing around a roller A rotating at higher speed than the feed rollers (not shown) prior to passing therebetween and one longitudinal edge of the fabric extends over the end of the end of the higher speed roller A and over a stationary roller B at one end of the roller A, provided with grooves or apertures therein for the passage of a light beam to a photo-electric cell c<SP>1</SP> which actuates mechanism to control the position of the fabric edge. In one embodiment, Fig. 1 (not shown), and 2 one end of the fabric 1 overlaps the end of the polished roller A and travels over the roller B formed with reduced-diameter grooves b, b<SP>1</SP> and mounted in a casing C housing a lamp c which projects light upwards through the grooves b, b<SP>1</SP> to the cell c<SP>1</SP> so that the light beam passes twice through the fabric. In a second embodiment, Figs. 3 and 4 (both not shown), the stationary roller B<SP>1</SP> is hollow and provided with two slots b<SP>2</SP>, b<SP>3</SP>, arranged so that when a light beam is directed from a lamp c through the slot b<SP>2</SP> on to a mirror b<SP>4</SP> at 45 degrees thereto it is reflected out through the slot b<SP>3</SP> on to the cell c<SP>1</SP>. In both embodiments, when the fabric edge deviates from the datum line the cell c<SP>1</SP> is energized to move the feed rollers longitudinally to bring the fabric back to the datum line. The feed rollers are mounted on sliding bolt brackets or a sliding platform and operated through a gear-box which electronically selected either a "forward" or a "reverse" clutch, the output of which is coupled through a friction loading device to a control arm directly coupled to the sliding bolt brackets.

The belt is resiliently urged downwardly by springs 51 acting on a longitudinally extending plate 50 bearing on upper flanges (26) (Fig. 14, not shown) of the shoes 20. Flanges (58a) limit downward movement of the belt when no bottles are being conveyed. An idler sprocket 41 of the chain (25) at the upstream end of the belt is eccentrically mounted on plates 35a which are pivotally mounted at 34 and are downwardly urged by a spring 38. A slot 34b permits additional upwards movement of the plates 35. The sprocket 41 may have eccentrically offset segments of teeth (Fig. 16, not shown) arranged in timed relation to the feed of the bottles. Certain of the shoes 20 may carry studs 22a (Fig. 13, not shown) on their bottleengaging surfaces. These are to enable the top horizontal surface of a bottle neck to be engaged without interfering with a label which projects slightly above the top of the bottle. The belt serves two separate labelling stations (U<SP>1</SP>), (U<SP>2</SP>) (Fig. 15, not shown).
