Abstract: 530,784. Opening roofs for vehicles. LATCHFORD, J. H. May 19, 1939, No. 14929. [ Class 108 (i)] A roof structure for motor cars comprises two or more slidable roof sections and a back section or panel. The sections are independently slidable and may all be slid into a rear compartment of the body. A rear roof section 19 is slidable by runners 24 on longitudinal rails 11 and a forward roof section 18 is slidable within the section 19 by runners 22 arranged to run on a rail 21 forming part of the section 19 and by forward runners 23 which run on the rails 11. The section 18 can thus be slid rearwardly into the section 19 or this section may be slid forwardly over the section 18. A back panel 20 can slide by runners 30 on the rails 11 and lower extensions 11b thereof into a compartment 38 in the boot 10. When this has been done and the section 18 has been slid into the section 19 until the forward runners 23, 24 reach a gap 35, Fig. 8, in the flange 14 of the rails 11, the front edges of these sections are lifted to enable them to be run on the rear runners 24 into a branch 11a of the rails disposed in the compartment 38. A gap provided in the flange 14 at the bead between the rails 11 and the branch 11a permits the passage of the runners 30 into the extension 11b but the engagement of studs 28 on the spindle of the rear runners 24 with flanges 16 off the rail guide these runners into the extensions 11a. A drip channel 12 for rain water is provided. The sections 18, 19 may each be provided with a device for locking them in position comprising a pair of bolts 32 connected to a central rotatable operating disc and adapted to enter holes in the rails 11.

Title: A method for manufacturing a semiconductor device and such device prepared thereby
Inventor: FUJINUMA KOICHI
IPC: H01L21/00
Filed: 1970-03-31
Abstract: 1,263,009. Semi-conductor devices. TOKYO SHIBAURA ELECTRIC CO. Ltd. 31 March, 1970 [31 March, 1969], No. 15039/70. Heading H1K. A transistor has a highly doped emitter region, a base region formed or augmented by ion implantation, and a base contact region adjacent to the edge of the emitter region. It is stated that the provision of adjacent highly doped emitter and base control regions does not adversely affect the emitter injection efficiency or the emitter junction capacitance. In a first embodiment, an N-type epitaxial layer (11) is grown on an N-type silicon substrate (20), the surface is oxidized (18), a window is opened to expose the emitter and base contact areas, a layer (17) of SiO 2  containing P is formed on the emitter area, the P is diffused-in to form the N-type emitter region (12) and B is diffused-in from a BN source to form the base contact region (16), Fig. 5A (not shown). The doped oxide layer (17) is then removed and B ions are implanted to form a base region (13) below the emitter region (12) and extending into the base contact region (16), Fig. 5B (not shown). The surface is then covered with a layer 19 of SiO 2 , the wafer is annealed, and windows are formed through which the emitter and base contacts 21, 22 are applied, and the collector contact 23 is applied to the lower face of the substrate, Fig. 5C. In a second embodiment, Figs. 6A to 6C (not shown), a window exposing the base contact and emitter areas is covered with a layer of SiO 2  doped with B which is then photoetched to expose the emitter area. The vapour is then heated to diffuse-in the B to form the base contact region, and P is diffused-in from the gas phase to form the emitter region. Oxide produced during diffusion is removed by etching and B ions are implanted through the emitter window in the doped oxide layer to form the base region underlying the emitter region. In a modification, Figs. 7A to 7E (not shown), B is diffused-in from the vapour phase simultaneously with the formation of the base contact region to form a base region the impurity concentration of which is augmented by ion implantation after the diffusion of the emitter region. In another embodiment, Figs. 8A to 8E (not shown), the base contact region is formed by diffusion of B using an oxide mask, the central part of the mask is removed and B is again diffused-in to form the base region. The surface is then remasked and the emitter region diffusedin followed by ion implantation to augment the impurity concentration of the base region below the emitter region. In a further embodiment, Figs. 9A to 9D (not shown), the base contact region is formed by diffusion from a B doped oxide layer as in the second embodiment but the base region is produced by ion implantation before P is diffused-in to form the emitter region.

Title: Improvements in Friction Lifters or Pullers and the like for Lifting the Tups of Drop Stamps or other purposes.
IPC: B21J7/44
Filed: 1916-10-25
Abstract: 110,586. Massey, B. & S., and Massey, H. F. Oct. 25, 1916. Driving-gear for winding and paying-out apparatus.-In friction clutches used for lifting the tups of drop stamps and for lifting, pulling, &c. generally, the clutch is operated by a cord, chain, or the like wound round the driving-shaft and automatically tightened thereon by a roller or other presser-piece alternately engaged and disengaged by tappets. The tup is carried by a band k adapted when raised to pass over a loose pulley k' and connected to arms a, b, adapted to be clutched to the driving-shaft c by a clutch band i operated by a spring y and by a lever i connected to a cord &c. s wound round a sleeve t turning with the driving-shaft c. A handle x on the cord s may be used for hand-operation. A roller or similar part 7, secured on a spindle 4 in a frame 2 pivoted on a sleeve z on the arm a, is adapted to press the cord into engagement with the sleeve t under the action of a spring 9 and lever 8. The spindle 4 may be geared to a toothed wheel 6 on the sleeve t, so that the rotation of the roller 7 assists to tighten the cord s. A cam 10 adapted to bear against the sleeve t to lift the roller and release the cord, carries a lug 12 and also a notch 18 adapted to be engaged by a spring catch 16. Fixed stops 13, 21 are provided and may be adjusted by racks 24, 25 and pinions 22, 23 to vary the distance of rise and fall of the tup. In the position shown, the catch 16 releases the cam 10 by the action of the stop 21 and the roller engages the cord, so that the clutch is engaged and the tup rises. When the lug 12 strikes the stop 13, the roller 7 is lifted, the clutch is disengaged and the tup falls, until the re-engagement of the catch 16 and stop 21 once more produces a lift. The lug 12 may be formed as a spring pressed pawl, Fig. 5, on the cam 10 to provide for the lug returning if it passes beyond the stop 13. The catch may hold the roller in the operative position, the spring 9 being used for disengagement. The roller may be stationary and the stops 13, 21 rotary. A brake m such as is described in Specification 11007/05, acting to stop the parts at the top of the lift, may be used, in which case it is normally kept out of action by a pedal.

Filed: 1942-10-30
Abstract: 564,477. Aircraft wings. STEVENS, A. H. (Stout Skycraft Corporation). Oct. 30, 1942, No. 15279. [Class 4] An aeroplane wing comprising a framework supporting a flexible covering has a series of holes 40 formed in its lower surface just in advance of the landing flap 14, the wing being otherwise imperforate, the holes being so positioned that at normal angles of attack they transmit to the interior of the wing the static pressure of the air passing over the lower surface, and at greater angles of attack they catch also a proportion of the kinetic energy of the flow to augment the internal pressure, in order to prevent vibration or flutter of the covering due to pressure changes on the exterior surface. The depression of the flaps 14 during landing assists the maintenance of a positive pressure at the holes 40. The flaps 14 and elevators 20 are interconnected so that as the elevators are raised to effect a landing they first move in advance of the flaps which are then depressed at an increasing rate as the elevators are further raised. This is effected by the linkage shown in Fig. 8 wherein a control lever 50 is connected by a link 56 to the upper ends of two levers 58, side by side, the levers having pins 78 working in slots 76 in levers fixed to shafts 68 carrying the flaps 14. A second link 62 connects the upper ends of the levers 58 to a horn 64 on the elevator shafts. U.S.A. Specification 1,777,593 is referred to.

IPC: G03F5/20
Filed: 1950-06-19
Abstract: 706,689. Producing intaglio printing surfaces. GRAVURE ENTERPRISES, Inc. June 19, 1950, No. 15312/50. Drawings to Specification. Class 98(2) An intaglio printing surface is produced by forming in a light-sensitive emulsion a latent image of both a half-tone image having picture forming elements or dots which are separated in the high lights and which coalesce or are connected together in the deeper tones, and of a uniform fine gravure screen of at least 300 lines per inch such that it divides the half-tone picture forming elements or dots, developing the emulsion, and utilizing it for the preparation of a printing surface. A light-sensitive film may be exposed first to a fine cross-line gravure screen, a half-tone image ink-printed on the exposed film and the latter further exposed, and the ink print removed, e.g. by washing in benzene. The film is then developed, fixed, washed and dried, and is printed on to a further film to produce a positive which is used to produce an etching resist, e.g. on "line tissue". The printing step may be avoided by processing the first film to a positive by reversal. The resist is applied to a copper-plated cylinder, which is given a single etching in a ferric chloride bath. The printing surface may be chromium plated. For colour printing, cylinders are so prepared for each of the colours yellow, red and blue, and for black. The positive may be prepared without the use of the fine gravure screen, and the resist prepared by printing from the fine screen and the positive. Films or resists bearing latent images of the fine gravure screen may be prepared in advance and stored. The ink-print of the half-tone image may be made on a thin transparent sheet and this photographically printed on to the film bearing a latent image of the fine gravure screen. The half-tone printing surface may be inked up and photographed, or an ink print therefrom may be photographed, the resulting photographic image being in each case photographically printed on to the film bearing a latent image of the fine gravure screen. In any of the above cases, the print of the half-tone image may be made first on the film to record the combined images, and the image of the fine gravure screen recorded subsequently. An ink-print of the half-tone printing surface may be made on to a transparent sheet, a film printed photographically therefrom, and this film and a negative fine gravure screen printed simultaneously on to a further film. Specifications 421,529 and 706,688 are referred to.

Title: Allocator of centralized devices for a timedivision switching exchange
IPC: H04Q11/04
Filed: 1972-04-04
Abstract: 1384726 Automatic exchange systems SOC ITALIANA TELECOMUNICAZIONI SIEMENS SpA 4 April 1972 [18 June 1971] 15475/72 Heading H4K In a TDM, PBX incorporating a plurality of recirculating memories for controlling connections between subscribers and either other subscribers or common equipments, e.g. outgoing junctors, senders, MF receivers and operators desks, the memories are also used as address generators which produce the addresses of each equipment in turn until one is found free whereupon its address is held in memory so as to indicate that it is allocated for use by the next demanding subscriber. Each memory contains the addresses of a particular type of equipment and it is arranged that equipments having a greater demand, e.g. operators and tone receivers, have their addresses in that memory having the shortest recirculating time. In addition a same operator's address may be caused to appear more than once in the cycle of common equipment addresses emanating from a memory, again so as to increase accessibility. A counter, which is stepped on once per exchange frame, presents at each step a three digit address that is compared by a logic with those present at the outputs of the recirculating memories during a particular phase of the memory devoted to the allocation process. The logic is also informed of the type of equipment with which it should concern itself; with the free/ busy status of an equipment address presented by the corresponding memory (this status having been determined by observing which equipment are busy on a call during the normal scanning of exchange time slots in each frame); with an indication as to whether an equipment is available (thus, although the exchange may be fully equipped it is possible that some equipments have not been commissioned for service); and with an indication as to whether an equipment of the type considered is wanted immediately for a call. Based on the above conditions the logic concentrates on one equipment type and examines one new equipment with each step of the counter until it finds an equipment free whereupon it records its identity in a memory and then proceeds to find a free equipment of another type. If a search is not effective within a certain number of steps i.e. whenever the "tons" digit of the counter reaches the value 11, it is interrupted by a search for an operator desk. During the latter search the counter is fed with a starting address by the relevant recirculating memory so that once a free desk is found a free connecting set associated with that desk can also be allocated. In the allocation of outgoing links incorporating, e.g. M.F. to D.C. signal converters, it is an additional condition of allocation that at least two be free.
