Title: Flashing electric lamp systems for road vehicles
Inventor: FREEMAN JOHN WILLIAM HERBERT
IPC: B60R16/03
Filed: 1961-03-07
Abstract: 1,015,851. Road-vehicle direction indicator systems. JOSEPH LUCAS (INDUSTRIES) Ltd. March 1, 1962 [March 7, 1961], No. 8300/61. Heading G4Q. A flashing direction indicator lamp system for a road vehicle can be used with batteries of two different voltages. The system is described with respect to a trailer which may be connected to a tractor having either a 12v. or a 24v. battery by connectors 3, 3a. Terminals 4, 4a, 5, 5a are connected over resistors 15, 16 to the trailer tail, number plate and stop lamps while terminals 8, 8a, 9, 9a are connected to the trailer direction indicator lamps which are operated selectively by a switch 13 and flasher 14 in the tractor. When a 12v. battery is in use, relay 17 is not energized and its contacts are as shown. If the tractor has a 24v. battery, however, relay contacts 17e open to insert dimming resistors in circuit with the tail, stop and number plate lamps and contacts 17a, 17b and 17c, 17d open and close, respectively, to insert choppers 20, 21 in series with the direction indicator lamps. On operation of switch 13 current flow to these lamps is thus converted to a square waveform as the selected chopper switch 20 is operated by the flasher current passing through winding 21 so that the R.M.S. value of the square wave is reduced to approximately 12 volts. A transistorized square wave generator operating in known manner is also described (Fig. 2, not shown), which may be used in lieu of each chopper.

Abstract: 1455787 Lathe tool-changers DSO ZMM 25 Feb 1974 [24 Feb 1973] 8527/74 Heading B3T A lathe having a carriage and a cross-slide with a tool mounting thereon incorporates a tool changing apparatus including a tool magazine the apparatus comprising a frame including a guide beam supported on the lathe bed by brackets 3 and 23 by way of rollers 24 and slide 2 so as to be movable along the bed, the beam carrying two slides 12 and 19 which are actuated by piston and cylinder means 9 and 14, so as to be transversely displaceable relatively to the lathe bed and to each other, the slide 12 carrying a pivotable transfer arm 13 actuated by a pair of hydraulically operated racks (45, 48), Fig. 5 (not shown), to pivot the arm between selected positions in relation to the frame to effect the tool change 9 transfer operation. The end of the arm 13 carries a tool engaging pin 20 on an arm 21 which pivots through a chain and sprocket connection 36, 37, 39 about an axis at the end of the arm 13 as the arm itself pivots whereby the tool engaging pin always traverses in a straight line parallel to the lathe bed and direction of movement of the lathe carriage and the frame along the bed. The slide 19 constitutes a conveyer unit having two tool unit carrying means 17, 18. In operation the frame is displaceable along the lathe bed and its position is controlled by stops and sensors 6, 7, 26, 31 to locate the transfer arm 13 and conveyer unit in a first position adjacent the lathe cross-slide and tool post and whereat the transfer arm is actuated to engage a tool unit on the tool post by the pin 21 and to transfer the tool to the receiving means 18 on the conveyer unit. The slide 19 is then actuated to align the new tool in the means 17 with the tool post and which is then subsequently transferred, by pivoting of the arm 13, to the tool mounting on the lathe cross-slide. The slide 12 is then moved to its uppermost position and the frame traversed along the bed to be positioned adjacent the tool magazine (not shown). The slide 19 is then actuated to align the used tool with the appropriate location on the magazine where it is transferred to the magazine by the pin 21 by pivoting of the arm 13. The slide is then again actuated to bring the carrier 17 into alignment with a selected tool in the magazine and which is subsequently transferred to the apparatus, ready for the next tool changing operation. The frame is then automatically displaced so as to follow the lathe carriage under the control of the stops so that the tool changing operation can be effected at the position it is desired. The use of the stops permits the automatic control of the tool changing apparatus as determined by the machining cycle.

Abstract: 966,249. Control of material level in hoppers. I. RUB. March 5, 1963 [March 6, 1962; July 6, 1962], Nos. 8607/62 and 25977/62. Heading B8S. The feed of material to hopper 10 from a conveyer is controlled intermittently by means of two flaps 11 and 12 pivoted within the hopper. Flap 12 is counterbalanced at 16 and employs an engaging lever 14a. Flap 11 is counterbalanced at 15 and employs engaging lever 13a. Control of the conveyer is effected by mercury switch 21 which is disposed outside the hopper on platform 17 pivoted at 18 and influenced at 19. Operation.-When the conveyer operates to feed material into hopper 10 so that the level of material bears upon flap 11, the latter is pressed downwards so that lever 13a engages platform 17a to tip the latter and operate switch 21 to shut off the conveyer. The level of material then falls as the material is discharged from the outlet of the conveyer. The level of the material falls till it ceases to weight upon flap 12. At this stage the flap 12 is operated by counterweight 16 to swing anticlockwise so that its lever 14a engages platform 17 to swing the latter upwards and clockwise to the position shown. Switch 21 is then operated to recommence the feed of the conveyer. Spring 19 operates to give a sharp up or down movement of platform 15.

Abstract: 1,082,319. Semi-conductor devices. WESTERN ELECTRIC CO. Inc. Oct. 14, 1964 [Dec. 17, 1963; Feb. 25, 1964; Aug. 7, 1964], No. 8614/67. Divided out of 1,082,317. Heading H1K. An integrated circuit consists of an array of substrate bodies (e.g. of semi-conductor material, though a thin-film circuit in which the substrate is of carbon or ceramic material is also envisaged), the bodies being joined by a pattern of metal contacts which extend substantially in one plane over the surfaces of the bodies and provide bridges between them. The bridging portions are of sufficient thickness to provide the only mechanical support necessary to maintain the bodies in their appropriate relative positions in the array. Each separate body may contain one or more elements of the circuit. The elements of the circuit are first formed (e.g. by conventional diffusion techniques) in a single substrate member and metallic deposits 117, 118 &c. are then laid down to provide the interconnections between the various elements. Such deposits may consist of sequentially deposited " active " and " contact " metals as described in Specification 1,082,317. The portions of these deposits which will ultimately provide the bridges 119, 120 &c. between the separate bodies are then built up by further deposition, e.g. to a thickness of 100,000  as against 1000 to 5000  for the deposits elsewhere. The electrode portion (the initial deposits) may be of platinum on titanium and the thickening produced by masked deposition of gold. The substrate material underlying the bridging portions is then removed, e.g. by etching with wax masking-though mechanical abrasion or ionic bombardment are also mentioned in this connection.

Title: Improvements in or relating to method and apparatus for production of high vacua
IPC: C09K3/10
Filed: 1961-03-09
Abstract: The working fluid of a diffusion type vacuum pump comprises a polyphenyl ether having from three to seven phenyl groups linked by two to six oxygen atoms arranged in a chain.  Separate isomers of the compounds may be used or mixtures of the ortho-, meta-, and para-isomers, and mixtures of polyphenyl ethers of different molecular weights may also be used.  The ethers may be prepared by interlinking halogen derivatives and then eliminating the halogen, the last traces of which may be removed by treatment with sodium ethoxide in ethanol.  Low boiling point impurities and oxidisable material are removed by prolonged moderate heating under vacuum or bubbling an inert gas or dry air at temperatures below 200 DEG C. through the ethers.  For greater purification, the above steps are followed by slow distillation under high vacuum, rejecting the first 1% to 5% and last 1-5%.  The boiling point range of the preferred ethers is 160 DEG C. to 300 DEG C. at 0.1 mm. pressure.

Title: Improvements in time mechanism for use in conjunction with gas controllers, electric time switches and other timing devices
IPC: F23Q9/02
Filed: 1927-04-01
Abstract: 295,296. Horstmann Gear Co., Ltd., and Horstmann, A. April 1, 1927. Driving-mechanism, main spring.-Clockwork mechanism for actuating a gas valve or electric switch in which a dial plate rotates once in a given period and carries adjustable levers for operating the valve or switch at predetermined times is further provided with a going barrel which has a bearing for the winding arbor which bearing is concentrically adjustable relatively to the barrel and carries the dial plate. The winding arbor B, Fig. 2, is mounted on the frame plates A and at one end has fixed to its squared end b<4> by means of a pin b<5> a ratchet wheel C which engages a spring-pressed pawl on the plate. These plates A also carry wheels on spindles a', a<2> connected with an escapement of the lever type and with a wheel a<5> which gears with a wheel d<3> on the going barrel D, which latter is mounted on the front end of the arbor B. Mounted freely in a hole at the front of the barrel and forming a hollow bearing for the winding arbor is a bearing member E, Fig. 9, which also has an enlarged hole e<2> to admit a key to engage the squared end b<1> of the winding arbor. The diameter e<3> freely but accurately fits the hole on the barrel D and the end e<5> abuts against the shoulder b<7> of the arbor B. Between a flange e<6>, integrally or otherwise attached to the member E, and the face d<5> of the barrel D is a friction disc e<9>, Fig. 14, and between the flange e<6> and a disc e<14> which fits loosely on the shoulder e<13> of member E is a second friction disc e<20>. Screws are passed through holes in the disc e<14> into holes d<7> in the barrel face d<5> so that by adjusting these screws the frictional relation between the barrel D and bearing member E may be adjusted. Fitting on the part e<15> of member E and against the shoulder e<16> by means of a slot e<8> and lug f<1>, Fig. 13, is the dial plate F which thus rotates with the member E and, through the friction discs e<9> and e<20>, with the barrel D. The plate F carries the usual levers f<2>, f<3> having pins f<5>, f<6> to operate the valve or switch. Pivoted at g' to the member E is a clamping member G similar to that described for the same purpose in Specification 23161/09. Thus the member E forms a bearing for the arbor B and a bush for the dial plate F and is the means whereby this dial may be adjusted relatively to a fixed index. Fig. 23 illustrates the clockwork gas controller attached to valve mechanism as described in Specification 293,714, [Class 135, Valves &c.]. Specifications 2588/13 and 189,476, [both in Class 135, Valves &c.], also are referred to.
