Title: Improvements in or relating to speed control mechanisms for knitting machines
Inventor: WAINWRIGHT CARLYLE HERBERT
IPC: D04B15/94
Filed: 1961-10-18
Abstract: Speed control mechanism is provided in a circular machine and comprises fast, medium and slow speed pulleys 3, 2, 1 Fig. 2, not shown, and belt shipping arms 51, Fig. 3, not shown, mounted on a bar 44 adapted to be shogged according to the dictates of cams 34 influencing pusher members 32 controlled by pattern chains 12 mounted on sprocket wheels on a drum shaft 11.  There are a series of chains 12 adapted to operate in conjunction with the control drum 7 and with striping mechanism controlling the yarn guides at each of three feeders of the machine.  The mechanism for causing the operation of the belt shipping arms 51 from each chain is similar and comprises a follower 17 adapted to be actuated by a link on the chain causing a lever 16 to depress a rod 21 whereby a lever 26 is advanced as a bell crank lever 24 is pivoted by the rod 21.  Normally a bluff lever 30 is retained with its nose 31 in a raised position whereby the pusher member 32 is held out of engagement with a cross bar on a member 35, common to all of the members 32 as it is reciprocated by the cam 34. When the rod 21 is depressed the advancement of lever 26 causes the lever 30 to pivot so that its nose 31 moves away from the pusher member 32 so that on the next movement forward of the member 32 the cross bar of member 35 is engaged whereby it is pivoted and caused to actuate a triangular plate 41.  The nose 41a of the plate 41 engages the bar 44 to move it against the action of a spring so that the bar 41 is shogged to move the belt from the fast to the medium or slow pulley.  The extent to which the belt is moved is dependent upon the shape of cam 34.  Consequently whenever a change of speed is required the appropriate pattern chain initiates a movement which results in the belt being shogged from the fast to the loose pulley.  A pivoted catch plate 56 attached to a rod 58 influenced by a lever 61 controlled by the cam drum 7 of the machine determines the length of time the belt remains in the medium or slow pulley.  The catch plate engages one of two notches in the bar 44 and retains the bar in the corresponding position until the cam drum releases it whereafter the belt is returned to the fast pulley.  Alternatively the cross bar of the lever 35 may be engaged by a catch member controlled by a cam on the same shaft as cam 34 whereby the lever 35 is retained advanced until released by this catch member in which position the lever 35 retains the belt on the appropriate pulley.

A device for automatic analysis of liquid samples, for example serum samples obtained by centrifuging blood samples in flexible tubes 14 supported in belt 12 movable on drums 13 comprises a belt 1 carrying flexible "working" tubes 2 and movable at right angles to the length of the tubes, press buttons 17 arranged in rows parallel to the tubes, means for moving each press button to press a portion of a working tube against a corresponding stationary member 18 (Fig. 3) to cause movement of the liquid along the tube, a second movable belt 7 carrying flexible tubes 9 containing auxiliary liquids for the analysis and means 10 for displacing the tubes to positions adjacent to the working tubes 2, each tube 9 having a needle 11 for injection of the auxiliary liquid into a working tube. In operation, serum is taken from a tube 14 into a working tube 2 through needle 5. At the same time sample information in the form of coded perforations in space 16 adjacent to the tubes 14 is read and transferred to the corresponding space 4 on belt 1 by punching the belt. Belt 7 may also carry coded perforations; movement of the belts 12, 1, 7 is controlled by a programming device reading the information on them. Belt 7 is moved so that a reagent tube 9 can be moved over the working tube by pin 10. Needle 11 is forced into the working tube 2 and reagent is sucked into the tube 2 by operation of buttons 17. The liquid in tube 2 may be filtered through sintered glass filter 6 by operating buttons 17. A reagent tube 9 may have two or more chambers containing different reagents in glass ampoules (95) (Fig. 2 not shown). These can be broken and the required quantities of each mixed by applying pressure to the reagent tube; the prepared reagent is then transferred to a working tube 2. There is reference to colorimetric determination of glucose using a farri-ferro cyanide reagent.

Title: Apparatus for producing digised signals for defining an amplitude modulated sub-carrier
IPC: H04N7/24
Filed: 1972-08-15
Abstract: 1432373 Analogue-to-digital and digital-toanalogue conversion INDEPENDENT BROADCASTING AUTHORITY 14 Aug 1973 [15 Aug 1972] 38075/72 Heading H3H Alternate, digitally-coded, samples (P1, P2, Fig. 3A and the analogue equivalents) taken of a signal M are reversed (Fig. 3B) and used to define the amplitudes of a notional subcarrier PC. Zeros are introduced between the samples to define the zeros of the subearrier. The system is used to convey t.v. signals between camera and transmitter. In one embodiment (Fig. 1, not shown) the modulating signal M is filtered (LPF) and sampled and digitized (A/D); the digitized samples are alternately reversed by a switch B which also defines the zero levels (Z). The result passes through a vestigial side band filter VSBF (details Fig. 2, not shown) and a group delay counter (GDC). A digital-analogue converter (D/A) and filter (LPF) may be used to derive the actual modulated subcarrier PC. In a second embodiment (Fig. 4, not shown) the signal M (Fig. 5A, not shown) is sampled (5B) and the samples converted (at ADC) to binary code. The binary coded signals are substantially halved in magnitude by dropping the 2 term; and then logic circuits (G) add a magnitude 2<SP>7</SP> to alternate signals and subtract the remainder of the signals from 2<SP>7</SP>. This effectively reverses alternate samples relative to a reference level (2<SP>7</SP>, Fig. 5D, not shown).

Title: Cyanoalkylsilanes and process for their production
IPC: C07F7/12
Filed: 1956-12-21
Abstract: The invention comprises cyanoalkylsilanes of the formula : <FORM:0847803/IV(a)/1> where B is a cyanoalkyl radical other than a cyanoethyl radical, free from cyano substitution on the beta carbon atom, R is a hydrogen atom or an alkyl, cycloalkyl, aryl or alkaryl radical, X is halogen or alkoxy or aroxy, m is 1, 2 or 3, n is 0, 1 or 2 and m + n is 1, 2 or 3.  The compounds in which X is alkoxy or aroxy are prepared by reacting a metal cyanide with a haloalkylhydrocarbyloxy silane, the haloalkyl portion being free from an ethyl radical as well as halogen substitution on the beta carbon atom, under anhydrous conditions in an organic polar solvent. Suitable metal cyanides are those of the alkali and alkaline earth metals.  Preferred polar solvents are dialkyl acylamides, particularly the formamides.  The compounds in which X is chlorine or a mixture of chlorine and alkoxy or aroxy groups are prepared from the purely hydrocarbyloxy compounds by reacting with a chlorinating agent such as phosphorus tri- or penta-chloride, benzyl chloride, thionyl chloride or silicon tetrachloride.  A long list of compounds is given.  The Examples describe the preparation of (1) (4), (7) and (8) gamma-cyanopropyl triethoxysilane ; (2) cyanomethyl triethoxysilane ; (3) alpha-cyanopropyl triethoxysilane ; (5) delta-cyanobutyl triethoxysilane ; (6) gammacyanopropyl dimethylethoxysilane ; (8) bis (deltacyanobutyl) diethoxysilane, tris (delta-cyanobutyl) ethoxysilane and gamma, delta-dicyanobutyl triethoxysilane ; (10) a mixture of gammacyanopropyl trichlorosilane and gamma-cyanopropylchlorodiethoxysilane.  The cyano groups can be hydrogenated to form aminoalkyl silanes, as in (9) in which epsilon-aminopentyl triethoxysilane is prepared from the delta-cyanobutyl derivative.  The aminoalkyl silanes are useful as sizes for glass fibres in the production of resin bonded laminates. Specifications 847,801, 847,802, 847,804 and 847,805 are referred to.

Abstract: 1,018,811. Semi-conductor devices. SIEMENS-SCHUCKERTWERKE A.G. Oct. 17, 1962 [Oct. 31, 1961], No. 39368/62. Heading H1K. In a semi-conductor device a metal member is pressed against an area of at least 10 mm.<SP>2</SP> of a semi-conductor body or metallized area thereof with a pressure of more than 50 kg./cm.<SP>2</SP>. At least one of the contact faces is uniformly pitted to a mean depth of 0À05 to 50 Á and both faces are substantially planar. The member may be of copper coated, on the contact face, with gold, silver, platinum or palladium. For instance a foil of silver may be attached to the copper by heating under pressure during manufacture or in the initial stages of operation. Typically the semi-conductor body is mounted between two pressure contacts but a molybdenum plate may alternatively be soldered to one face of the semi-conductor wafer, if it is of silicon or germanium. At the pressure contact the semi-conductor surface may have metallic conduction due to heavy doping or coating with metals such as nickel, gold, silver, palladium, gallium, aluminium or indium. Such coatings are provided by electroplating or vapour deposition, by attachment of foils or in the case of gallium, by rubbing it on the surface. The typical device shown in Fig. 4 is made first by diffusing phosphorus into both faces of a 200 ohm./cm. P-type silicon wafer from phosphorus pentoxide vapour. After lapping one surface to expose the original wafer material boron is diffused into this from boron trioxide vapour. The edge of the wafer is then removed by spinning the wafer about its axis while a jet of etchant is directed at its edge, and the face roughened to a depth of 0À5-50 Á by lapping. Roughened silver foil 7 and wafer 5 are placed as shown on a molybdenum plate 4 hard soldered to copper base 2 and the sub-assembly with its associated dished springs 14, 15, 16 and mica centring washer 12 clamped over them by turning rim 2a over the lip of cup 17. Finally the metal and ceramic cap 20 is sealed to the base. Triodes, four layer switching devices, photo-elements, and solid circuits based on silicon, silicon carbide and A III BV or A II B VI  compounds may be similarly mounted.
