Patent GB-1178402-A (GB)
Title: Improvements in Switching Devices.
Inventor: DUNNING GEORGE ERNEST
IPC: H01H3/40
Filed: 1966-05-24
Abstract: 1,178,402. Time switches. G. E. DUNNING, and J. R. HAWKINS. 7 Aug., 1967 [24 May, 1966; 12 Oct., 1966], Nos. 23022/66 and 45646/66. Heading H1N. [Also in Division G3] A device for producing a signal at predetermined times of day comprises two coaxial rotary wafer switches each comprising a wiper movable over twelve fixed contacts. The switches are arranged in-line on a drive shaft but the wipers are freely rotatable thereon, being driven by pinion gears mounted on their respective stators. The shaft is driven by a clock mechanism at, say, one revolution in five minutes and a disc secured thereon having, in effect, one gear tooth on its circumference engages the first pinion once per revolution to step the first wiper from one fixed contact to the next. A similar single-toothed disc secured to the first wiper moves the second wiper one step for each revolution of the first wiper, i.e. each hour. Thus a signalling circuit connected to the two wipers can be completed at any desired time (to the nearest five minutes) by interconnecting a selected fixed contact of one switch to a selected fixed contact of the other switch. More than one pair of fixed contacts may be interconnected to provide a signal at a plurality of times. If the signal is not to be repeated in the succeeding twelve-hour period, or if a different time is required, a third wafer switch is provided in series with the others and driven by a similar stepping drive from the wiper of the second switch. This third switch may have fourteen fixed contacts, corresponding to the twelve-hour periods in a week, thereby providing a predetermined weekly programme. If a number of separate signalling circuits are required to be closed at different times, a first wafer switch is provided for each circuit, all driven by the first stepping drive, and a common second wafer switch is stepped by the wiper of the end one of the first wafer switches. In order to ease the load on the drive at the instant of stepping a " snail " cam is secured on the drive shaft to lift a spring-loaded follower slowly until at the instant of stepping it drops suddenly, assisting the shaft to rotate. A dog clutch with lost motion couples the clock drive to the shaft so that the steps may occur with a snap-action. In order to facilitate changing programmes the fixed contacts may be wired to a socket for interchangeable printed-circuit boards on which interconnections may be preset by means of plug-in leads. Diodes are provided in these leads to avoid unwanted interaction when a plurality of circuits are being controlled.

Title: Manufacturing semiconductor devices
IPC: H01L21/761
Filed: 1967-10-18
Abstract: 1,206,427. Semi-conductor devices. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 18 Oct., 1967 [21 Oct., 1966], No. 47387/67. Heading H1K. In a semi-conductor integrated structure comprising complementary PNP and NPN transistors, formed in N(P)-type islands 4, 5 defined in an epitaxial coating 3 on a P(N)- type substrate 2 by P(N)-type frames 6, a relatively low resistivity P(N)-type buried layer 9 underlies the island 4 containing the PNP (NPN) transistor to form part of the collector region thereof and to define a relatively narrow base region. In the silicon structure shown the P-type buried layer 9 is formed by diffusion into the N-type epitaxial layer 3 from a heavily borondoped region formed in the surface of the substrate 2 prior to deposition of the layer 3. The lower portions of the frames 6 are formed in the same manner simultaneously with the layer 9, and a buried N-type layer 12 beneath the island 5 containing the NPN transistor is similarly provided by redistribution of arsenic from a region diffused into the substrate 2. The upper portions of the frames 6 and the remaining regions 7, 8, 10 of the two transistors are diffused into the layer 3 using oxide or nitride masking, the dopants being boron for regions 6, 8 and 10 and phosphorus for region 7. The preferred sequence of processes is to commence the diffusion of the frames 6 alone, then to interrupt this process and to complete it simultaneously with the diffusion of the regions 8 and 10. Electrodes are provided as shown, a further electrode being optionally provided on the lower face of the substrate 2. In further embodiments the buried P-type layer 9 beneath the PNP transistor is isolated from the substrate 2 by a further buried N-type layer (31), Figs. 5 and 7 (not shown), formed either completely within the substrate (2) (Fig. 7) by deeper diffusion than that which produces the layer (9), or partly within the substrate and partly within the epitaxial layer (3), (Fig. 5) by virtue of a very heavily doped N-type region (36) diffused into the substrate surface, prior to deposition of the layer (3), to include and overlap on all sides the P-type region which gives rise to the layer (9). In these embodiments the buried P-type layer (9) is connected to the upper surface of the epitaxial layer (3) by a P-type region (33), e.g. annular in shape, diffused in from the upper surface, preferably simultaneously with the formation of the upper portions of the frames (6). In an alternative form the base zone of the NPN transistor may be common with the emitter zone of the PNP transistor. The semi-conductor body may include several PNP and/or NPN transistors, and diodes, resistors, capacitors &c. may also be included. Reference has been directed by the Comptroller to Specification 1,047,388.

A driving abutment 5, pivotally mounted at 9 on a truck frame 6 having wheels 7 running along an overhead rail 36, is movable into an operative position shown in which it is engageable by a driver 2 on an endless driven chain 1 provided with rollers running along a track 3a, and movable by a driver into an inoperative position in which it is completely clear of the path of movement of the drivers 2 on the chain 1, by means of an over-dead-centre spring 10 connected at 11 to the frame 6 and at 12 to the abutment 5. The latter is locked in the operative position by a horizontally slidable bar 4 mounted in the frame 6 and under the urge of a spring 16. An arcuate locking projection 13 of the abutment centred at 9, has a face 14 engaging the top of the bar 4 and a stop 15 engaging one end of a slot 19 in the bar. When a buffer head 17 on the bar 4 engages a vertically movable track stop (not shown) the bar is moved against its spring 16 until the slot 19 is aligned with the flank 20 of the projection 13. When a driver 2 then engages the abutment it is pivoted until the spring 10 snaps over-deadcentre to retain the abutment 5 in its inoperative position in which it is also secured by the locking bar. The abutment 5 may be returned to the operative position by moving the track stop which is also provided with a member to engage a stud 21 on the finger. The truck is provided with a second abutment 24 pivoted at 25 on the frame 6 and urged into an operative position by a spring 26. The spring permits a driver 2 to ride over the abutment 24, the latter preventing overruning of the truck.
Patent GB-1030754-A (GB)
Title: Novel d-nor steroids and processes for their manufacture
IPC: C07J75/00
Filed: 1962-12-20
Abstract: The invention comprises D-nor-steroids and a process for the production thereof by dissolving a steroid substituted in the D-ring by a keto group and by a diazo group in a position a - to the keto group, in an inert solvent containing a compound which can be added across the double bond of a ketene, photolysing the solution and isolating the D-nor-steroid thus produced.  By employing a 16-diazo-17-keto androstane or estrane dissolved in an inert solvent containing water, ammonia, an alcohol or primary or sec. amine, there is produced a D-nor-16b -carboxylic acid, carboxylic amide, carboxylic acid ester or -N-mono- or disubstituted-carboxylic acid amide.  Further transformations may be effected, e.g. by converting the D-nor-16b -carboxylic acid to the corresponding acid chloride, followed by reaction with an organo-metallic compound or with diazomethane to form a D-nor-pregnane derivative, degrading the D-nor-pregnane derivative to obtain a D-nor-androstane derivative which on pyrolysis gives a D-nor-estrane derivative.  The starting a -diazo-keto steroid may be obtained by reacting the corresponding a -oximino-keto steroid with chloramine.  Pharmaceutical compositions containing the above compounds and having estrogenic, androgenic, anti-inflammatory, cortical, cholesterol-lowering, anabolic, progestational and antifertility activity are administered orally or parenterally.

Abstract: 1,204,139. Boots &c. BRITISH UNITED SHOE MACHINERY CO. Ltd. 24 Oct., 1967 [25 Oct., 1966], No. 48195/67. Heading A3B. A lasting machine of the type having a work support (not shown), wipers (not shown) and tack driving mechanism including a main tack driving lever 1 and an oscillating tack hopper 60, has a piston 19 and cylinder 17 device which oscillates the tack hopper 60 and a control arrangement including a valve which is operated as a result of movement of the tack driving level 1. The lever 1 is pivoted at 3 to a link 2 which in turn is pivoted to the machine frame K. A rod 6 having a cam follower (not shown) is pivoted to the lever 1 at 5, the cam follower being urged into contact with a cam (not shown) on a cam shaft 8 by a spring 10. When the rise of the cam moves away from the cam follower the lever 1 is moved smartly downwards by the action of spring 10 to drive the tacks (not shown). A block 52 may be moved by a handle 55 and lever 56 to a position under a shoulder 53 on the rod 6 to render the tack drivers inoperative e.g. if a further wiping operation is required. The tack drivers are supplied with tacks each time the hopper 60 is oscillated by a piston and cylinder 17 operating through a rack 21 and pinion 22. Operation of the piston and cylinder 17 is controlled by a shuttle valve V 3  and valves V 2 , V 1  as follows: - when the tack driving lever 1 moves downwardly valve V 2  is shifted to allow fluid to flow from a supply 40, through ports 41, 45 to pilot port 46 to shift valve V 3 . Fluid then flows through ports 43, 47 to raise the piston 19 which causes cam 36 to operate valve V 1 . Fluid then flows through ports 42, 48 to pilot port 49 to return the valve V 3  to its original position and thus lower the piston 19. Thus the tack hopper is only operated when the tack driving lever 1 is operated, no tacks being supplied if the lever 1 is stopped by the block 52 as described above.
