Title: Improvements relating to ships' sliding windows
IPC: B63B19/00
Filed: 1931-06-04
Abstract: 377,367. Ship windows ; window regulators. PATE, G., MERCER, J. H., and BACON, H. R., of Carron Co., Carron, Stirlingshire. June 4, 1931, No. 16150. [Class 20 (iii).] A ship window of the kind which is raised and lowered by screwnut mechanism 4, 5, acting on a carrier 2 to which the sash is connected by wedges and inclined slots which force it against packing 6 when closing, has a sash supporting arm 8 on a bell-crank lever which rests on the cross member 7 of the carrier. The arm 11 of the bell crank is tilted to disengage the support 8 when the window is closed, and sliding of the sash in the carrier causes engagement with the packing 6 ; at the same time the sash is moved over a fixed support 13. On opening, the reverse operations take place. The screw is rotated by bevel gearing 15, 16 and a handle.

Title: Improvements relating to beam deflecting circuits for cathode ray tubes
Inventor: JAMES IVANHOE JOHN PENFOUND
IPC: H03K4/43
Filed: 1948-06-16
Abstract: 668,726. Saw-tooth generating circuits. ELECTRIC & MUSICAL INDUSTRIES, Ltd. June 15, 1949 [June 16, 1948], No. 16157/48. Class 40 (vi). In a saw-tooth current generator of the type in which a saw-tooth voltage generated by varying the charge on a capacitor rapidly in one sense and by means of a resistor slowly in the other sense, is fed to an amplifier the output of which supplies an inductive load, the resistor is connected between the capacitor and the load whereby the potential to which the capacitor tends during the slow variation by virtue of the current through the resistor depends only on the current in the load circuit. A capacitor 3 is charged rapidly through a diode 1 from a positive source 2 (e.g. the cathode resistor of a blocking oscillator) and is discharged slowly through resistors 4 and 18 to produce a sawtooth wave. This wave is amplified by valves 7 and 8 which may be D.C. coupled (as described in Specification 456,450) and applied to the scanning coil 17 of a cathode-ray tube. The voltage developed across resistor 18 by the output current controls the rate of discharge of the capacitor through a resistor 4 such as to maintain the voltage across the resistor 4 constant and thus ensures a linear sweep. The voltage developed across the output resistor is also applied as negative feed-back to the cathode of the first valves. A resistor 16 damps oscillations initiated during the fly-back and may be replaced by a diode damping circuit. Coil 17 may also be shunted by a damping resistor which may have a capacitor in series with it to prevent coupling of the negative feedback path with an adjacent line scanning coil. The amplitude of the output may be varied by adjusting resistor 4. According to the Provisional Specification a positive-going saw-tooth generator may be employed in which case valve 7 is replaced by a cathode coupled pair, the saw-tooth being fed to the grid of one valve and the negative feed-back being applied to the grid of the other.

Title: Improvements in or relating to magnetic records
IPC: G06K19/08
Filed: 1954-06-01
Abstract: 770,455. Statistical apparatus. RUSSELL, E. W. C. Aug. 19, 1955 [June 1, 1954], No. 16184/54. Class 106 (1). ). Data is recorded upon one surface of a document such as a cheque 10 by applying a coating 11 of magnetic material having blank spaces 14 to represent certain information and subsequently removing further areas of the coating by punching holes 15 in the document, these holes representing further information. Both sets of spaces 14, 15 are sensed simultaneously in a magnetic scanning device. The magnetic coating is applied by printing or by photographic methods and may represent information common to a series of documents, e.g. for a cheque, the name of the bank and the method of clearing. The perforations 15 may represent information particular to the cheque concerned, e.g. the amount and the name of the drawer. Room is left on the cheque or the like for such endorsements as are necessary. Such records are sorted by being passed in succession over a series of magnetic rollers, one of which is energized according to the data sensed to draw the record into the appropriate pocket. Specification 655,357 is referred to.
Patent GB-685571-A (GB)
Title: Improvements in apparatus for polishing the rims of vehicle wheels and like rings
Inventor: WHALE GEORGE HENRY
IPC: B24B5/44
Filed: 1950-06-29
Abstract: 685,571. Polishing wheel rims. DUNLOP RUBBER CO., Ltd. June 21, 1951 [June 29, 1950], No. 16237/50. Addition to 595,534. Class 60. The machine described in the parent Specification is modified in that one of the rim-positioning rollers drives the rim and only one polishing mop 24, Fig. 1, is used. Three rollers 6, 7, 12, Fig. 2, are mounted on a frame 1 pivotally supported on trunnions 3 and connected by a lever 16 with a hydraulic cylinder (not shown). A second hydraulic cylinder is mounted for adjustment in guides 15 on the frame 1 and is adapted to displace the roller 12 into and out of engagement with the rim 25 to be polished. The roller 7 is mounted for pivotal adjustment about a stud 9 and is driven by an electric motor 20 through a reduction gear unit and a shaft with two universal couplings 18. When the frame 1 is forwardly inclined, a rim is placed on rim-supporting brackets between the rollers and the motors 20 and mop motors are switched on. A pedal 21 is then depressed first to advance the roller 12 so that the rim is gripped by all three rollers and lifted from the brackets, and then to cause the cylinder connected to lever 16 to pivot the frame 1 to a horizontal position in which the rim is in contact with the mop. When the pedal is again depressed, the frame 1 is inclined before the roller 12 is retracted. The delay between these two movements may be obtained by supplying fluid at different pressures to the two cylinders. The mop, which is inclined so as to treat only one half of the rim at a time, is driven by a motor 22 adjustably mounted in guides 23. It may be replaced by a mop shaped to treat the whole width of the rim in one operation and mounted about a vertical axis on a horizontal slide adapted to be moved hydraulically to and from the rim. A cover 28 mounted on trunnions 29 is raised and lowered automatically with the pivotal movement of the frame 1 to and from operative position by a cam-piece 31 co-acting with a roller 32 on the frame. The casing 26 has ventilation slots 27 and a suction hood (not shown).

Abstract: 749,771. Stand heads. SLUTZKY, N. J. May 6, 1954 [June 12, 1953], No. 16241/53. Class 52(3). An adjustable support for electric lamps or other fittings comprises a ring slidable through a transverse opening or aligned openings in a support member and held in adjusted position by spring means, in the support member, pressing against the ring. As shown in Fig. 3 a tubular support member 9, ring 11, and lamp shade 23 are secured to a stand 31. A tubular shutter 12 is notched at 16 to receive the ends of an angularly adjustable split ring 11 passed into a slot 10 in the support 9, the shutter being urged by a spring 13 to clamp the ring against a washer 18 and being adjusted by a screwed plug 14 locked by grub screws 20. The ring is slidably received in a groove 25 in a nipple 26 which is secured in a boss 22, and to the lamp shade 23, by a nut 29 to give universal adjustment of the lamp. According to the Provisional Specification the ends of a split ring are engaged in a threaded tubular nipple receiving the screw thread of a standard electric lamp holder, the ring being received in a transverse slot in a tubular support housing a tubular shutter which is pressed down against the action of a spring to allow the ring to be inserted in the slot.

Title: Improvements in the manufacture of foam-generating substances
IPC: A62D1/02
Filed: 1938-05-31
Abstract: 517,767. Peptones ; foaming agents. PYRENE CO., Ltd., and RATZER, A. F. May 31, 1938, No. 16302. [Classes 2 (iii) and 15 (ii)] [Also in Group XXI] Foam generating substances are prepared by degrading keratins, albumins, globulins or haemoglobins by means of an oxide of an alkaline earth or magnesium oxide to a point at which more than 25 per cent. of the nitrogen present in its water soluble products is in the form of peptones or to a point at which 30c.c. of a neutral 1 per cent. aqueous solution of the products when shaken for five seconds in a 500c.c. flask give a foam having a volume at least six times that of the solution. Ground animal horns and hoofs, dried blood, and soya bean meal are suitable raw materials. Pea flour and maize meal may also be used if the starch is first extracted. A salt, e.g. a calcium salt may be present during the hydrolysis. When lime is used to effect the degradation a salt may be formed by adding a little hydrochloric acid. The foam produced by means of the products may be stabilized by the addition of a salt which by hydrolysis yields an insoluble hydroxide. Ferrous and ferric salts are suitable for this purpose. In an example, horn and hoof meal is boiled with water in the presence of slaked lime and calcium chloride. The product is neutralized with sulphuric acid boiled to remove undesirable gases and concentrated or evaporated to dryness. The use of barium and strontium oxides and elevated pressures is mentioned.

Title: Improvements in turning indicators for aircraft or the like
IPC: B64D45/00
Filed: 1921-12-22
Abstract: 191,676. Stewart, C. J., Stainer, W. W., and Burn, L. Dec. 22, 1921. Gyroscopic apparatus.-In an instrument in which the angular motion of an aeroplane &c. is indicated by the precession of a suitably mounted and restrained gyroscope, the precession is utilized to operate a shutter or shutters serving to cover or to expose to direct view one or more lamps &c. for giving a successive or cumulative illuminative indication. An arm 10 secured to the precession axis 11 carries a pin 12 projecting between two shutters 13 mounted coaxially with the arm 10. The shutters are counterbalanced by springs 14 &c. and are mounted in front of a series of lamps 17 or an illuminated tube 18 &c., so that an increasing number of lamps or length of tube is visible as the rate of turn increases, The shutters are recessed at 19 so that the central lamp 20 is always visible. In the form shown in Fig. 2 a circular shutter 21 has a single aperture 22 adapted to expose the lamps one by one as the shutter is turned. The central lampmay be above the shutter so as to be constantly visible. The lamps on the two sides may be differently coloured.

Title: Improvements in gun mountings and like directional mountings
IPC: F41A27/22
Filed: 1951-07-11
Abstract: 681,076. Ordnance mountings. BREVETS AERO-MECANIQUES, SOC.-ANON. July 31, 1951 [July 11, 1951], No. 16425/51. Class 92(i) A gun is trained by gearing such as 29, 43, 45, 5 about a normally vertical axis by a pair of pedal levers 19 arranged to be thrust, as desired, by a seated operator through free-wheel clutch mechanism. Depression of the left pedal lever 19, Fig. 2, causes a rod 22 to rock a cam-operating lever 24 whose shaft is journalled in the cover plate 26 of a drum 27 and whose cam is adapted to open out a pair of shoes 31 into contact with the inner surface of the drum 27 which is fast on the stub shaft 28 of the gear 29. The shoes are pivoted at 33 on the plate 26, and thus serve to couple the plate 26 to the drum when the pedal is depressed, continued depression of the pedal serving to rotate the drum and thus the gearing. The other pedal acts in a similar manner and the gun is thereby trained about a fixed base 1 in one direction or the other according to which pedal is depressed. The arrangement is such that by exerting a sudden thrust on a pedal the mounting can freewheel in the direction imparted by such thrust. Elevation of the barrel 12 is effected by handles 16 connected fast with the trunnion journals 10 or geared to the trunnions or linked to the gun. In order to counterbalance the weight of the gun at. all times, a spring mounted in a telescopic housing 49 is anchored at one end to an arm pivoted to the training structure 7. A chain connected to the other end of the spring passes around a drum on a spindle 54, Fig. 6, rotatably mounted in a casing 50 on the gun cradle 11. On each recoil of the gun a ramp 60 on a recoiling part engages a roller 59 on a lever 58b whose other arm 58a serves to rock a stirrup 56 carrying a pawl 55. The pawl, by engaging a ratchet wheel 53 on the shaft 54 thereby imparts a step-by-step rotation of the drum and increases the tension of the counterbalancing spring to compensate the diminishing weight of the magazine.

IPC: C08G73/10
Filed: 1967-04-11
Abstract: 1,136,535. Polyamide acid solutions. GENERAL ELECTRIC CO. 11 April, 1967 [5 May, 1966], No. 16439/67. Heading C3R. [Also in Divisions B2 and C7] A polyamide acid solution is made by (1) forming in water a mixture comprising (a) at least one dianhydride selected from benzophenone tetracarboxylic acid dianhydrides, pyromellitic dianhydride, ethylene glycol bistrimellitate anhydride and (b) at least one diamine selected from C 2-8  alkylenediamines, m-phenylenediamine and where R is C 1-3  alkylene, (c) a water-soluble t-amine, with or without a water-soluble sec. amine, and (2) allowing the reactants to interact at a temp. below 40‹ C. to form the polyamide resin. Many polyamideforming reactants are specified. Monoamines or dicarboxylic acid anhydrides may be used to chain stop or modify the polymers. Optimum concentrations are 5-40% (by wt.) of polymer and 60-95% of solvent mixture comprising 15-75% of amine additive and 25-85% of water. Water-soluble amine additives specified are: t-amines-pyridine, dimethylethanolamine, N - ethylmorpholine, and N,N,N<SP>1</SP>,N<SP>1</SP>- tetramethylbutanediamine; and sec. aminesdiethylamine and morpholine. Cyclization of the polyamide acids to polyimides is effected by heating at 125-300‹ C. In a typical Example (1) powdered 3,3<SP>1</SP>,4,4<SP>1</SP>-benzophenonetetracarboxylic acid dianhydride and pyridine were added to an aqueous solution of 4,4<SP>1</SP>- methylenedianiline to yield a heterogeneous mixture to which 3 portions of pyridine were then added to yield a viscous polymer solution; a sample of this solution was cast on a glass substrate and heated to 80‹ C., and the resulting film was heated to 300‹ C. to yield a clear, tough polyimide film. Uses: for making films and fibres; electrocoating Cu or Al substrates (see Division B2); as dipping varnishes for impregnating coils of insulated wire; in moulding powder formulations by mixing with wood flour, diatomaceous earth, carbon, silica, carborundum or diamond grit; as impregnants and bonding materials for laminates; and as dielectrics in making capacitators or as slot insulation in motors.

Abstract: 689,196. Distributing music &c. AUTOMATIC TELEPHONE & ELECTRIC CO., Ltd. June 19, 1951 [July 1, 1950], No. 16473/50. Class 40 (iv). In a wired broadcasting system each receiver station circuit is arranged to be closed by a relay which may be local or at a control station under the control of a coin-actuated device at the subscriber's premises and resetting of the relay is effected by switching at the control station. Coin-operated contacts CC, Fig. 1, on closing complete the circuit to a loudspeaker transformer TRC from either of the output transformers TRA, TRB at the control station according to the position of a multibank selector switch PS. An electromagnet A, which has a short-circuited winding to lower its impedance, resets the contacts CC when D.C. is applied to the lines by push-button switches RS at the control station. In a modification, Fig. 2 (not shown), the electromagnet A has two cores and also controls a pair of contacts in the loud-speaker circuit. The coin-switch contacts energize the relay to complete the circuit by discharging a condenser which is connected across one of the programme lines in series with a rectifier. In a further modification the relay is actuated by signal power and in another the relays which are housed at the control station are reset manually. Specifications 518,877, 650,242 and 680,562, [both in Group XXXVII], are referred to.
