Title: Improvements relating to windscreens for vehicles
IPC: B60J10/02
Filed: 1936-06-04
Abstract: 476,239. Windscreens ; vehicle windows. SHAW, G. R. June 4, 1936, No. 15658. [Class 20 (iii)] A windscreen 1 for a vehicle is formed so as to be self-supporting on the scuttle 3, and to make weather-proof joints with the forward edges of doors or side windows. The screen may be made of glass, preferably toughened, or synthetic transparent material, and may comprise sections joined by fillets 14, 15 of the same material, or of metal, screwed together. The screen is secured by screws directly to the roof and scuttle. The meeting edges of the screen and side window may be halved or bent, as shown in Figs. 5 and 6, the joint being suitably displaced with respect to the hinge so as to separate when the door is opened. Alternatively, the screen and door windows may have interlocking edges, the door window being lowered before opening the door when the door is hinged at the rear edge. To prevent damage to the window in the latter modification, the door latching mechanism may be connected to the window regulator so that the window is automatically lowered when the door is opened.

Title: Process for modifying the tinctorial properties of proteinic fibres
Filed: 1952-06-24
Abstract: Natural or artificial proteinic fibres are given a reduced affinity for wool dyestuffs which draw from an acid or neutral bath by impregnating them with an acid solution containing sulphamic acid or a derivative thereof which has the group -NH-SO3H and which is capable of splitting off sulphamic acid on heating, and then subjecting the impregnated fibres to a heat treatment whereby a reaction between the sulphamic acid and the fibre takes place.  The solution may contain a swelling agent for the fibre such as urea, thiourea, formic acid, acetic acid, formamide, acetamide and phenol. Solutions of sulphamic acid or its derivatives such as imido-sulphonic acid or its ammonium salt or the pyridine salt of carbamide sulphonic acid in water or other solvents such as formamide may be employed.  Examples describe the treatment of wool, silk and artificial protein fibres and in some examples the treated fibres are employed as effect threads in woven wool fabrics and remain undyed when the fabric is dyed with acid wool dyestuffs.  Specifications 512,618 and 648,883, [Group IV (a)], are referred to.

Title: Improvements in the separation of materials
Inventor: UMNEY LAURIE EDWARD RICHARD
IPC: A24B5/10
Filed: 1952-06-27
Abstract: 730,200. Pneumatic separating. VOKES, Ltd. May 1, 1953 [June 27, 1952], No. 16305/52. Class 117. A mixture is continuously conveyed into a zone traversed by an upwardly-flowing airstream which entrains lighter or less dense particles which are removed by a centrifugal separator, a portion of the airstream being returned to said zone while another portion is by-passed through a dust-recovery filter. A jigging conveyer 1 carrying tobacco-leaf shreds and stalks has a perforated portion 2 between the mouths 4, 6 respectively of ducts 3, 5. Air from fan 15 passes through the material, the leaf and dust being conveyed up the vertical duct 5, round corner piece 7, divided into sections 7a, 7b, 7c of reduced area into the horizontal section 8. The latter leads into a centrifugal separator 9 the material outlet of which is provided with a rotating valve passing the leaf to shoot 22 and conveyer 23. The air from outlet 13 of separator 9 is fed to the inlet 14 of the fan 15. A branch 17 from duct 3 is led to a bag-type dust-recovery filter 18, clean air being returned through outlet 19 to the inlet pipe 12 of the fan 15. The mouth 6 of the duct 5 has an arcuate section bulge at its trailing edge to accommodate eddies at this point.

Title: Data display systems
IPC: G09G1/04
Filed: 1971-05-20
Abstract: 1336043 Cathode-ray tube displays SIEMENS AG 21 May 1971 [22 May 1970] 16468/71 Heading H4T In a data display system of the type on which symbols are produced on a display screen by appropriate deflection of a beam, circuitry detects the "end-of-writing" condition in any line of data and operates to produce a voltage reset pulse which positions the beam at a new destination point within a constant line. As shown, a key-board 23 supplies data to an image repetition store comprising fine ultrasonic circulating delay stores 26-30. which control a fixed word store 36 holding a sequence of 12-bit words for each character symbol, of which 9-bits are relevant to the present invention. These, which are transferred via a coordinate register 37 in response to an output from AND gate 38, comprise two groups each of 3-bits specifying the differential-X co-ordinates and the differential-Y co-ordinates which are fed to respective registers 42, 43, two single bits specifying the sign of the differential deflections, which are fed to respective registers 41, 44 and a single bit specifying the ON-OFF beam condition which is fed to register 45. In operation, sampling circuits 46, 47 respond to the presence of bits in registers 42 and 43 to close switches 50, 51 which pass pulses from a timing generator 31 to count registers 42, 43 down to zero and via switches 52, 53, which are set in accordance with the sign bits in registers 41, 44, to operate UP-DOWN counters 58, 59 and to supply the co-ordinates to D/A converters 61, 62 from which the beam deflection quantities are derived. When a new line of data is to be produced presetting signals (together with fly-back signals) are supplied to the counters 58, 59 from a counter 33 (which controls the input of data from the key-board 23 to the registers 26-30) and monitoring registers 1, 2 then operate via D/A converters 3, 4 to modify the outputs of the D/A converters 61, 62 such that the beam is moved to the required position in a constant time which is independent of the positions of the starting and destination co-ordinates. The display means may be a cathode-ray tube or may be produced by selective deflection of a light beam on a luminescent screen.

Filed: 1939-06-05
Abstract: 521,183. Adjusting wireless apparatus. PHILIPS LAMPS, Ltd. June 5, 1939, No. 16482. Convention date, June 8, 1938. [Class 37] The movements of station selecting keys or their equivalents are transmitted to a tuning condenser through a spring. The shaft 1 of the condenser 2 is urged in one direction by spring 15 and rotated in the other direction by pinion 3 and sector 4 under the influence of spring 8 when the member 6, which is free upon the shaft 5, is depressed to a determined amount by one of the buttons 7. Movement of the condenser is damped by the dashpot 13, and continues until the stop 9 comes into contact with the member 6. Due to the presence of this stop and a preliminary tension in the spring 8, the correct position of the condenser, dependent upon the position of the keys 7, is assured. The application of the invention to a three-section gang condenser of the slidableelectrode form is also described, Fig. 2 (not shown).

Abstract: 487,176. Spray carburetters. PALLAS APPARATE GES. June 14, 1937, No. 16516. Convention date, June 12, 1936. [Class 7 (iii)] In a pressure regulator for a floatless carburetter of the anterior throttle type, the regulator comprising air and fuel chambers separated bv a diaphragm controlling the fuel supply valve, the air chamber is connected to an air pump which is either mechanically connected to the throttle valve or is pneumatically operated by the pressure on the engine side of that valve to cause a change in pressure in the air chamber when the throttle is opened or closed and thus increase or decrease temporarily the fuel supply, the change in pressure being neutralized after an appropriate interval by air entering the air chamber through a restricted opening. A pump piston o actuated by the throttle i forces air past a pressure valve r through a pipe s to the dry side of a pressure regulator comprising a diaphragm c and fuel chamber b, the additional pressure displacing the diaphragm to open the fuel inlet valve a and force additional fuel through the nozzle g. A calibrated orifice v in a tube connecting the air chamber t to the air inlet h, regulates the duration of the additional charge. The valve. r may be omitted and the air chamber vent back into the pump, closure of the throttle valve then causing a reduced fuel flow. The suction valve q of the pump may normally be open and close only on the pressure stroke of the piston o. In a modification, a bellows with its interior communicating with the mixing chamber replaces the piston pump and the throttle connections thereof.
