Title: Improvements in or relating to collision warning and collision avoidance systems
IPC: G01S11/08
Filed: 1961-11-16
Abstract: 975,278. Electronic computers. BENDIX CORPORATION. Nov. 16, 1961 [Nov. 18, 1960], No. 41108/61. Heading G4A. [Also in Division H4] The Specification relates to an aircraft collision-avoidance radar system (see Division H4) and incorporates a digital computer for calculating the necessity for manoeuvring to avoid collision between aircraft. It is demonstrated mathematically that no manoeuvre is necessary if where 2n + 1 measurements of a quantity S, representing the difference in distance between direct and ground-reflexion pulses between the aircraft Fig. 1 (not shown), are made regularly over an interval 2n #t, F is a number determined by n, the time required to perform a manoevre, and #t, and xi = S 1 /2Z 1  where Z 1  is the altitude of the "protected" aircraft. Values of 2n + 1 = 5 and of F = -5 are chosen. The computer comprises a buffer unit 1100 receiving "h" data (where h is a height difference outside which collision is considered to be unlikely) and "S" data for all intruder aircraft and storing them on Separate tracks on a magnetic storage drum, Fig. 10C (not shown), a programmer 1300, an arithmetic unit 1400, and an "active" unit 1200 which stores in a given channel for any one aircraft time, "h" and-five successive values of Y = (1/x -x), and as a new. value of Y is added the oldest Y value is erased. The terms (1 + 5i) are supplied to the arithmetic unit from a permanent store in the drum. The arithmetic unit first computes a value So, which determines whether an immediate threat of collision exists and the mathematical formulation of which is derived in the Specification, and the second computation removes the S value from buffer 1100 and replaces it with a Y value. Arrangements for parity checking in the computer are disclosed. A detailed description of the computer is given with reference to Figs. 11.. 14 (not shown).

Title: Steroid compounds
IPC: H01R4/02
Filed: 1957-03-27
Abstract: The invention comprises a 21-triphenyl-methyl ether of a steroid of the general formula: <FORM:0864612/IV (b)/1> wherein R1 represents H(H), H(OH) or O and R111 represents (H)COCH2OH or (OH) COCH2OH and the corresponding 4a , 5- and 4b , 5-epoxides, and D 1-dehydrocortisone 21-triphenylmethyl ether, and the preparation of the compounds of the above general formula by reacting the required free 21-hydroxy compound with a triphenylmethyl halide e.g. triphenylmethyl chloride in solution in anhydrous pyridine, and the preparation of the 21-triphenylmethyl ethers of the corresponding 4, 5-epoxides by reacting the compounds of the above general formula with hydrogen peroxide under alkaline conditions.  The etherification process is preferably carried out by heating the reactants together on a water bath for a period of from 1 to 8 hours.  If the reactant contains a secondary alcoholic group, it is preferable to employ only sufficient of the triphenylmethyl halids to etherify the 21-hydroxy group.  The 21-triphenylmethyl ethers of the above general formula may be separated from the reaction mixture by diluting it with ice, extracting the precipitate thereby produced with gasoline to remove triphenylcarbinol, and recrystallising the residue from an organic solvent under acid-free conditions.  The 21-triphenylmethyl ethers of the above general formula may be acid hydrolysed to form the corresponding free 21-hydroxy compounds.  In the examples deoxycorticosterone, cortisone, D 1-dehydrocortisone, and D 4-pregnene-17a , 21-diol-3 20-dione 21-triphenylmethyl ethers are prepared; cortisone is prepared by refluxing the corresponding 21-triphenylmethyl ether with acetic acid; a mixture of the 4a , 5- and 4b , 5-epoxy-allopregnane-17a , 21-diol-3, 11, 20-trione 21-triphenylmethyl ethers are prepared by treating cortisone 21-triphenylmethyl ether with an aqueous solution of sodium hydroxide and hydrogen peroxide, and the 4a , 5-epoxy compound is then heated with acetic acid to form 4a , 5-epoxy-allopregnene-17a , 21-diol-3, 11, 20-trione; deoxycorticosterone acetate is prepared by treating D 5-pregnene-3b , 21-diol-20-one with triphenylmethyl chloride to form the corresponding 21-triphenylether, oxidising the 21-triphenylmethyl ether by the Oppenouer method to form deoxycorticosterone 21-triphenylmethyl ether, refluxing this compound with acetic acid and acetylating the resulting deoxycorticosterone; cortisone acetate is prepared by treating D 4-pregnene-11a , 17a , 21-triol-3, 20-dione with triphenylmethyl chloride to form the corresponding 21-triphenylmethyl ether, oxidising this compound to form the 21-triphenylmethyl ether of cortisone, refluxing the ether with acetic acid to form cortisone and acetylating to form cortisone acetate.  Specifications 838,771, 838,772, 838,773, 864,608, 864,610, 864,611, 864,613, 864,614 and 864,615 also are referred to.

Title: Arrangement for regulating the idling torque of a motor-vehicle engine
IPC: B62D15/02
Filed: 1962-10-31
Abstract: 972,618. Controlling motor vehicles. DAIMLER-BENZ A.G. Dot. 31, 1962 [Nov. 4, 1961], No. 41255/62. Heading B7H. [Also in Division F1] In a vehicle with power-assisted steering the hydraulic pressure which provides the power assistance is arranged to act on a piston 36 against spring pressure to increase the idling torque of the vehicle engine as the said hydraulic pressure increases to prevent stalling of the engine. As shown, accelerator pedal 8 forms part of linkage controlling the position of throttle valve 4 and fuel injection pump 6, engine idling being controlled by member 38 through roller 41 which contacts lever 11 of the linkage. The member 38 is responsive to both the gear-box condition and the hydraulic steering pressure. Engine-driven pump 19 supplies hydraulic fluid to steering control unit 33 which, in dependence on movements of steering wheel 29 varies the pressure of fluid supplied through pipe 35 to both the steering ram 32 and piston 36. Increasing hydraulic pressure on piston 36, opposing the pressure of spring 37, moves the piston and rod and the lower end of member 38 downwards, rotating the member about stop 39 and hence increasing the idling speed of the engine. Pump 19 also supplies hydraulic fluid to the control unit 2<SP>1</SP> of gearbox 2, which incorporates a plate clutch 16 and hydrodynamic clutch 15. On movement of lever 21 to engage drive hydraulic fluid is supplied through line 22<SP>1</SP> both to the ram which engages clutch 16 and through line 24 to close electro-hydraulic switch 26 and hence energize electromagnet 27 which moves pin 28, constituting the armature, downwards, pushing the upper end of member 38 to abut stop 40 instead of stop 39 and thus increase the idling speed and torque of the engine. Both pin 28 and the piston-rod of piston 36 may be adjustable in length and roller 41 may be adjusted in position on member 38. Specification 972,617 is referred to.

IPC: F16K17/19
Filed: 1958-12-22
Abstract: 862,224. Valves. AMERICAN CAN CO. Dec. 22, 1958 [March 13, 1958], No. 41305/58. Class 135. [Also in Group XVII] A valve arrangement for equalizing the pressure between the exterior and interior of a container comprises a resilient member 10, Fig. 4, attached to a wall 4 of said container adjacent an aperture 18 in this wall and defining with the wall a channel 16 with permanently closed sides to define a passage for fluid flow between the exterior and interior of the container, the member 10 being unattached to the wall 4 at one part at least and co-operating with the wall at this part to provide a resilient valve, In Fig. 2 the internal surface of the container 4 has an arcuate strip of flexible thermoplastic material 12 cemented in position along its longitudinal margins 13, except for its end 14. If a cap 22 is removed to expose a dispensing nozzle and the container is squeezed to expel the contents, the strip 12 is forced against the wall 4, particularly at the part 14, to form a seal over the hole 18. If a reduced pressure occurs inside the capped container, the strip 12 will deflect to open the channel 16 and permit air to enter. In the case of a container containing coffee, the member 10 may be applied externally to relieve carbon dioxide generated by the coffee. Specification 798,069 is referred to.

Title: Apparatus for controlling the movement of an element through a work station
IPC: G06K13/067
Filed: 1965-09-29
Abstract: 1,095,681. Record feeding. INTERNATIONAL BUSINESS MACHINES CORPORATION. Sept. 29, 1965 [Oct. 12, 1964], No. 41467/65. Heading G4M. Documents are fed from a stack 10 by belts 12, 13 aligned in transit by rolls 15, 16 and the leading edge of each document is detected by a photo-cell at 21. After a predetermined delay (111), Fig. 5 (not shown) a bi-stable circuit (102) is reset to release the clutch driving feed belt 26 and apply a brake so that the document is stopped at a predetermined position in reading station 20 and a part of the document may then be scanned by a, cathode-ray tube. After passing through a further delay element (116), the delayed leading edge signal sets another bi-stable circuit (117) to engage a clutch coupling an emitter (80) to the drive shaft of belt 26. The emitter may comprise a disc bearing one or more marks sensed by a photo-cell or magnetic transducer, or a contact-wiping switch. In response to a start pulse the bi-stable circuit (102) is set, and the belt 26 and emitter (80) are driven in synchronism. When the emitter generates a pulse, the belt 26 is again stopped so that another part of the document can be scanned at the reading station 20. In this manner, several parts of the document may be scanned in turn, as determined by the emitter (80). When the leading edge of the next document is detected at 21, the emitter clutch is released and the emitter is spring-returned to a datum position.

Title: Improvements in or relating to the manufacture of tube like structures
Inventor: BARLOW BORIS VICTORIEN
IPC: B21C37/12
Filed: 1962-11-07
Abstract: 1,022,295. Coiling. S. SMITH & SONS (ENGLAND) Ltd. Oct. 25, 1963 [Nov. 7, 1962], No. 42024/62. Heading B3E. In a method of making a tube of the kind formed by winding wire helically with consecutive turns touching or spaced apart axially to form outer members for flexible drive shafts hardened steel wire, of rectangular section is drawn by driven rollers 5, 6, 7, 8 and driven with a small force into the space between three uniform cross-section rollers 1, 2, 3 driven at the same speed and symmetrically skewed about an axis 4. The wire is fed in a plane at right angles to the roll 3 by which it is tangentially deflected and thus helically bent. The newly formed helical turns are moved axially and compressed radially by the rollers 1, 2, 3 which work harden the surface thereof. The apparatus comprises an electric motor and chain driven gear 20 which drives the three rollers via three substantially identical gear train sets, skew and radial roller adjustment means and strip feed means. Roller 1 is driven via spun gears 21, 24, bevel gears 30, 32, 34, 35 and spun gears 37, 38. The gear 34 is axially slidable along the splined end of a shaft 33 journalled in a member 41 which is rotatable about the axis thereof to adjust the skew angle of the roller, via a bolt 44 on an arm 43, attached thereto, engaging a slot on a plate 47 rotatably mounted on a bearing 48 and angularly adjustable by means of an eye bolt 49 engaging a bolt 50 connected to a main frame 19. Each roller and its immediate gear train is similarly skewed by the common actuating plate 47. The radial adjustment of the roller assembly 1 and similarly roller assemblies 2, 3 is made by rotating a worm 56 to drive a wormwheel 55, screwed to a sleeve 74 surrounding the member 41 and which is secured against rotation by a key 75, which causes the sleeve 74 to move vertically and carry the member 41 and hence the roller assembly therewith. The feed rollers 5, 6, 7, 8 are mounted in a structure 100, bolted to an equivalent member 41 of the drive arrangement to roller 3, so that it is automatically adjusted when any adjustment 1 is made to the roller 3, and are individually driven via a gear train from a take-off gear coupled to the gearing of the roller drive assembly 3. The whole apparatus including the wire storage reel may be rotated in the opposite direction of rotation to that of the formed member 12 and at the same speed so that the member leaves the apparatus in a non-rotating condition.

Abstract: 1334253 Stamping BETHLEHEM STEEL CORP 7 Sept 1970 [5 Sept 1969] 42701/70 Headings B3A and B3Q In the deep drawing of seamless metal articles, sheet steel is used which has a metallic coating on both sides, the coating on one side having a thickness to provide a lubricity no greater than that of the substrate and the coating on the other side being such that it provides a lubricity greater than that of the substrate, whereby when the coated steel is passed through an ironing die with the coating on said one side adjacent the punch and the coating on said other side adjacent the die which makes a semi-cone angle with the punch in the range greater than 2 degrees and up to 8 degrees, the shear stress will counteract the longitudinal tension so that reduction in excess of 50% can be achieved, while longitudinal tension is held below the fracture limit. As shown, Fig. 1, the wall thickness H B  of a shallow drawn blank is reduced to H A  in one pass through an ironing die 11 by a punch 10. Suitable metallic coatings for said other side include brass, tin, zinc and copper and the lower lubricity of the coating for said one side may be achieved by using a different metal, e.g. chrome-chromium oxide, or a lesser thickness of the same metal e.g. a tin coating of weight up to 0À051 lb/b.b. on said one side and 0À25-0À50 lb/b.b. on said other side. The preferred die angle relative to the punch is between 4 and 6 degrees.

Abstract: 1326087 Remotely controlled rear-view mirrors HAPPICH GmbH GEBR 10 Sept 1970 [10 Sept 1969] 43360/70 Heading B7J In an exterior rear view mirror assembly adjustable from inside the vehicle, a mirror 1 is mounted by means of a bracket arm 3 in a housing 4 for tilting about a first axis, the housing 4 being connected by means of a pivot pin 6 and an offset lever 17 to a grip 20 mounted inside the vehicle, the grip being movable to effect rotation of the mirror about a second axis corresponding to the longitudinal axis of the pivot pin 6; the pivot pin has a tapered conical portion 7 fitting into a socket 9, and a cylindrical shaft portion 8, integral for movement with an externally tapered socket 14 fitting into a sleeve 16 attached to the lever 17, the tapered portions 14 and 7 of the two couplings being urged into frictional engagement with their respective socket portions by a spring 13. The coefficient of friction between 16 and 14 is arranged to be greater than that between 7 and 9. As shown in Fig. 2, the grip 20 has a pin 19 which moves inside a slot 18 in the lever 17. Movement of the grip 20, which is limited by the end faces of a mounting 22 moves the pin 19 in the slot and hence the lever 17, which, by means of the frictional coupling between 16 and 14 effects rotation of the mirror about the second axis. Rotation of the mirror manually from outside the vehicle about the second axis may be performed, as a result of the difference in friction between the couplings, without corresponding movement of the grip 20.
