Title: Amplifiers
IPC: A61B5/04
Filed: 1970-08-20
Abstract: 1322219 Variable gain amplifier AMERICAN OPTICAL CORP 20 Aug 1970 [25 Aug 1969] 40147/70 Heading G4H [Also in Division H4] Maximum value of an input signal during a monitoring period is detected and controls the gain of an amplifier during a subsequent period. As described the input signal is full wave rectified by an operational amplifier arrangement 10 to provide a voltage on capacitor 52 which is dependent on the peak value of the input signal. The voltage on capacitor 52 is fed to one input of a comparator circuit 20 to the other input of which is fed a reference signal on line 22. The reference signal is derived from a counter 40 so that it steadily increases with the count of counter 40. In a gain setting operation switch 74 is momentarily closed which resets bi-stable 50, and counter 40 to its zero count state. With bi-stable 50 reset, pulses from oscillator 60 are fed to the counter 40 which has its stages connected to the resistors 30 to provide a stepped increase in the reference voltage to comparator 20. When the reference voltage equals the voltage on capacitor 52 the comparator output causes the setting of bi-stable 50 so that gate 56 is closed and the count then existing in counter 40 is held static. The state of the counter 40 causes the conduction of a corresponding selection of the FETs T1-T32 to insert respective resistors 1600R-50R in the negative feedback path of amplifier 58 so that the gain of that amplifier is set to a corresponding level. The set of resistors 30 which control the reference voltage production, and the set of resistors in the feedback path of amplifier 58 are both arranged in binary progression so that their effect is linearly related to the count in counter 40, and the amplifier gain is therefore set to be inversely proportional to the detected input signal peak.

Filed: 1965-09-22
Abstract: 1,064,807. Feeding and winding webs. INTERNATIONAL BUSINESS MACHINES CORPORATION. Sept. 22, 1965 [Oct. 16, 1964], No. 40354/65. Heading B6B. [Also in Division G5] Tape driving apparatus comprises a capstan for driving the tape at constant speed and variable speed auxiliary drive means at the feed and take-up sides of the apparatus for controlling the feed and take-up speeds of the tape in response to tension in the tape. Feed arrangement.-Release of tape brake 3, Fig. 1, and movement of pressure wheel 4 into contact with constant speed capstan 6 commences feed of the tape to a process station (not shown). The resulting increase in tension in the tape lifts a brake 27 from the feed reel 1 and also moves a lever 9 forming part of the pulley storage arrangement A in a clockwise direction against the action of spring 11. Thus cam 24 on lever 9 first contacts a pivoting lever 20 and via pressure wheel 16 moves the tape into contact with capstan 12 which is driven at a slower rate than capstan 6 and then subsequently into contact with capstans 13, 14 and 15 each rotating at a higher speed than its predecessor. The lever 9 finally oscillates between a position in which its cam 24 moves the tape into contact with capstan 15 which rotates at a speed greater than capstan 6 and a position in which the cam moves the tape into contact with capstan 14 which rotates at a speed below that of capstan 6. Take-up arrangement.-On commencement of feed of the tape 5 the lever 32, Fig. 2, of the pulley storage arrangement D is moved in a clockwise direction by spring 34 to take up the slack in the tape. This movement releases brake 58 of the take-up reel 2 and also moves a cam 47 on the lever into contact with pivoting lever 43 which in turn moves a roller 39 into contact with a drive wheel 35. Roller 39 is coupled to a further wheel 48 which drives the take-up reel 2 via belt 52 at a speed such that the tape take-up speed is less than the feed speed produced by capstan 6. Thus lever 32 continues moving in a clockwise direction coupling the take-up reel drive in turn to drive wheels 36, 37 and 38, each rotating at a higher speed than its predecessor. The lever finally oscillates between positions in which its cam either couples the reel drive to drive wheel 38 which produces a take-up speed greater than the feed speed or to drive wheel 37 producing a takeup speed less than the feed speed.

Abstract: 1,126,615. Doped zinc tungstate crystals. MULLARD Ltd. 23 Sept., 1965, No. 40558/65. Heading C1A. Zinc tungstate crystals doped with at least two impurity ions are grown from a melt of component oxides in which the distribution of impurities in the grown crystal is determined by the presence in the melt of an excess of one of the major components, two of the impurities are such that there is a positive interaction between them, this means that an increase in the amount of one impurity in the oxide melt causes the distribution coefficient of the other impurity to increase, where distribution coefficient is defined as the ratio between the concentration of an impurity in the solid state and the concentration of the impurity in the melt. Preferably the distribution coefficient of one impurity is maintained greater than 1 and that of the other impurity is maintained less than 1 but preferred respective values are given as between 0À5 and 2À0 and less than 0À1. These values of distribution coefficient are preferably maintained by the presence of an excess amount of tungstic oxide. The specified impurities are chromium and lithium, the chromium may be added initially as chromium nitrate which decomposes under the melt conditions to the corresponding oxide; the lithium may be added to the melt as lithium tungstate. The distribution coefficient of the chromium may be maintained at a value substantially equal to unity by the presence of an excess of zinc oxide. The desired values of the distribution coefficients of the impurities may be adjusted and maintained before starting to grow the crystals and also said values may be adjusted and maintained during growth if desired.

Abstract: 1,170,065. Thermal radiation control coating. NORTH AMERICAN AVIATION Inc. 12 Sept., 1966 [10 Sept., 1965], No. 40597/66. Heading B2K. [Also in Division F4] A method for coating a thermally emittive surface with a composite thermal radiation control coating having a low ratio of solar absorptance to thermal emittance (not more than 0.40/0.85) comprises coating the thermally emittive surface with a first layer of a mixture consisting aluminium phosphate, chromium oxide, nickel oxide, and cobalt oxide, heating the layer to form a first cured film, coating the first cured film with a second layer of a mixture consisting essentially of stannic oxide and aluminium phosphate, and heating the second layer to form a second cured film adhering to the underlying first cured film. The coatings may be applied as aqueous slurries by spraying. The first aqueous slurry may consist of a chromium-nickel-cobalt spinel say comprising of chromium oxide, nickel oxide, and cobalt oxide in a 0.75:1.00:0.25 molecular ratio, mixed with silicon dioxide, and aluminium phosphate. The thermally emittive surface may be a metal surface such as copper, aluminium, or a metal alloy, or a thin film of a high temperature glass may be first applied on the metal surface. The composite coating may be discontinuous. Metal substrates mentioned include copper, copper-coated steel, steel, aluminium, titanium, beryllium, with and without intermediate layers of glass. The substrate may be cleaned prior to coating and mechanically roughened say by grit blasting. The total thickness of the composite coating may be between 1 and 5 mils. In the examples the products are subjected to various tests, including nuclear, electron and ultra-violet irradiation studies, and heating tests, and the heat transfer efficiency of the coatings is determined by the heat emittance and solar absorptance. The coatings are said to be effective for a thermal control surface operative in a space environment.

Abstract: 1,130,412. Portable containers; rotary conveyers. A. R. RAUSING. 13 Sept., 1966 [8 Oct., 1965; 6 May, 1966], No. 40911/66. Headings B8A and B8D. [Also in Divisions B3 and B5] In a method of making sleeved containers, two halves t and b are deep drawn (see Division B5A) in moulds 2t<SP>1</SP> and 2b<SP>1</SP> carried by intermittently rotating conveyer members T17<SP>1</SP> and B17<SP>1</SP> respectively. The members are then indexed to bring the drawn halves into opposition and the moulds are forwarded into co-operation to weld the halves together. Finally the welded containers which are retained by moulds 2t<SP>1</SP> are indexed to a position III in which they are inserted into sleeves h carried by a third intermittently rotating member H17<SP>1</SP>, this member then being indexed to a take-off station. The sleeves are fed along a pair of channels H9 by, e.g. conveyer belts and are located in the desired arrangement within frames H10 by rotating pinions H5 and H7. The sleeves are subsequently pushed down on to mandrels carried by member H17<SP>1</SP> by sets of rams H12. During rotation of T17<SP>1</SP> to its welding position, each mould 2t<SP>1</SP> is moved radially outward by a cam mechanism (see Figs. 5, 8, 9a and 9b, not shown) and, after said welding position has been reached are moved further outward into cooperation with moulds 2b<SP>1</SP> by further operation of the above cam mechanism. After welding the moulds are retracted and during the next indexing movement the same two movements of the moulds 2t<SP>1</SP> are effected to insert the welded containers into the sleeve. The container comprises an inner hollow body formed from two moulded halves t and b welded together around flanges f1 and f2, and on outer sleeve h the end of which has been rolled over to form a rim r.

Title: Tube rolling

Filed: 1974-09-20
Abstract: 1487614 Rolling tubes FRIEDRICH KOCKS 20 Sept 1974 [24 Sept 1973] 41026/74 Heading B3M The initial passes in a multi-pass stretch reducing mill for tubes, which serve to build up tension in a tube, have their speeds so arranged that a rapid build up in tension occurs, in order to reduce the extent of thickened end portions of the tube which normally occur in rolling. The first of the initial passes of the mill produces a rearward pull on the tube (due to the tube moving at a faster speed than the peripheral speed of the rolls) whereas the last of the initial passes provides a positive traction force. The maximum traction force is arranged by driving the rolls of a stand at such a speed that the rolling radius (i.e. the region where the tube and a part of the roll groove are moving at the same speed) is equal to the radius of the groove base. The c value is then 1 where c= (WD-2R)/D, and WD is double the distance between the roll axis and tube axis, R is the rolling radius, and D the outer diameter of the tube. For the first of the initial stands c may be 0À35 or less. In the case of a mill with 24 stands, the first 6 may build up tube tension, and their c values will progressively increase from 0À35 to 1À0 or more. The mill stands may be driven by a group drive or by individual motors although the former is preferred.

Title: Preparation of olefinic alcohols and borates
IPC: C07F5/04
Filed: 1961-11-16
Abstract: The invention comprises olefinic borate esters of the formula (RO)3B in which R1 is an olefinic radical of 6 to 30 carbons and to which the oxygen is connected at the carbon atom alpha to the double bond. Olefinic borate esters are made by forming a mixture of boric acid or boric anhydride and an olefinic hydrocarbon containing 6 to 30 carbon atoms per molecule, oxidizing said mixture in the liquid phase by contacting it with an oxygen-containing gas introduced at a rate of from 0.4 litre to 50 litres per hour, expressed in terms of oxygen content, at a temperature of 60 DEG  to 190 DEG C. and for a period of 4 hours to 160 hours, and separating an olefinic borate ester. The olefine may be open chain or cyclic, many examples being given. When operating at temperatures near or above the boiling point of the olefine, superatmospheric pressures are used to maintain the liquid phase. The olefinic borate ester may be hydrolyzed to the corresponding unsaturated ester by heating with water, if desired with addition of a mineral acid.  Typical conditions are between 50 and 100 DEG C. for between 10 minutes and 1 hour. In examples (1) tri(cyclohexenyl)borate is made and hydrolysed to 2-cyclohexenol and bis (3-hydroxy -2- cyclohexenyl) ether; (2) mixed borate esters are obtained from dodecene-1 and then hydrolysed; (3) a mixture of 2-ethylhexene -1 and boric acid is oxidized and the product hydrolysed to a mixture of isomeric olefinic alcohols; (4) an isomeric mixture of alcohols of a -pinene is similarly produced. Specification 944,110 is referred to.
