Title: New colouration process for textile materials
Inventor: MOYSE JAMES ALBERT
IPC: D06P1/52
Filed: 1957-11-22
Abstract: Textile materials are coloured, locally or otherwise, and given a crease- or shrink-resistant finish or a modified handle by treating them with an aqueous medium containing a resin forming composition known to produce a crease-resistant or shrink-resistant finish or a modified handle, an acid catalyst and a dyestuff containing a reactive halogen atom or other group capable of reacting with the resin or fibre to become attached thereto through a covalent bond, optionally drying the treated material and finally baking, e.g., at 130 DEG -170 DEG C.  Specified resin forming compositions are epoxy resins, polyisocyanates, modified glycol acetals and the condensation products of formaldehyde with cresols, acrolein, urea, thiourea, dicyandiamide, dicyandiamidine, biguanides, amides, carbamates, allophanates, aminotriazines, urons, ureides, ureins, imidazolidones, triazones, hydantoins, and polyamides and lower alkyl ethers of such condensation products.  Specified acid catalysts are zinc chloride, ammonium sulphate, ammonium chloride, mineral acid salts of organic amines, weak acids such as oxalic acid and acidliberators such as magnesium chloride and ammonium thiocyanate.  Specified reactive dyestuffs are of the nitro, azo, anthraquinone, and phthalocyanine series and specified reactive groups are triazinyl groups substituted by chlorine or bromine atoms or by sulphonic acid, hydroxyl, unsubstituted amino, guanyl hydrazide, semicarbazide or thiosemicarbazide groups, halogen substituted pyrimidinyl groups, b -halogenopropionyl-, b -halogenoethylsulphonyl-, b -halogenoethylsulphamyl-, b -sulphatoethylsulphonyl-, b -hydroxyethylsulphonyl-, chloroacetylamino-, b -(chloromethyl) -b - sulphatoethylsulphamyl-, alkyl phospite- and sulphon fluoridegroups.  Suitable dyestuffs are those described in Specifications 209,723, 298,494, 460,224, 733,471, 740,533, 751,997, 775,308, 772,030, 774,925, 780,591, 781,930, 785,120, 785,222, 802,198, and 805,562.

Title: Nestable plastics containers
IPC: B65D1/26
Filed: 1965-08-25
Abstract: 1,123,401. Nestable plastics containers. MONSANTO CO. 25 Aug., 1965 [26 Aug., 1964], No. 36514/65. Addition to 1,063,811. Heading A4A. [Also in Division B8] In a nestable plastics container such as a drinking cup suitable for vending machines and having a bottom wall 2 and a side wall S tapering upwardly and outwardly to an open upper end, a part 14 of the outer surface of the skirt 1 of the side wall is foamed, e.g. by the method set out in Specification 1,063,811, an annular stacking shoulder 7 is formed in the side wall spaced downwardly from the open upper end, an annular supporting shoulder 5 is formed in the side wall spaced downwardly from the stacking shoulder, the supporting shoulder of one cup resting on the stacking shoulder of a like cup in which it is nested so that the foamed outer wall part is spaced from the unfoamed inner wall to prevent wedging of the nested cups. The bottom wall is formed as a double-conical base having a foamed inner part 4 which is at a greater angle to the plane passing through the bottom edge of the side wall than the outer part. The maximum thickness of the unfoamed part of the side wall is .010 inches and of the foamed part .022 inches the container being dimensioned so that the foamed part lies within a line joining the rim 30 and the bottom edge of the side wall so that the foamed part of the side wall does not contact the wall of a feed shoot of a vending machine and free fall is not inhibited. In a modification for use in vending machines in which the feed shoot is not vertical or is curved the co-operating stacking and supporting shoulders have a greater area of contact to more securely hold the cups against relative movement which would bring the foamed parts into contact with the inner surface of a lower cup in a stack or with the wall of the feed shoot.

Title: Pneumatic keyboard
IPC: B41J23/22
Filed: 1961-10-11
Abstract: 950,343. Keyboards. SPERRY RAND CORPORATION. Oct. 11, 1961, No. 36519/61. Heading B6F. [Also in Division G4] A key 7 for a pneumatically operated calcula. tor consists of a port 11 which is blocked by the finger of the operator. This increases pressure in passage 13 and thus directs an air stream, normally flowing from passage 19 to passage 25, into passage 27. A reset signal later appears in passage 29 under the control of means not described to deflect the air stream back into passage 25. In order to give an operator the feel of a normal keyboard, the port 11 may be in a button which when touched moves against the action of a spring (Fig. 2, not shown). A hinged flap may cover the port 11 and be the means of actually blocking the port. The direction of flow of the stream from passage 19 may be used to enter data into a store, or to control punching or printing operations.

Title: Improvements in or relating to cam cutting machines
IPC: B23Q35/12
Filed: 1932-12-28
Abstract: 395,603. Cam-milling machines. TRIGGS, W. W., 57, Lincoln's Inn Fields, London.-(Pratt & Whitney Co. ; 436, Capitol Avenue, Hartford, Connecticut, U.S.A.) Dec. 28, 1932, No. 36703. [Class 83 (iii).] In a cam - cutting machine such as that described in Specification 297,263 [Class 83 (iii). Metals, Cutting], wherein a cam blank 25 is moved in front of a cutter 3 under the control of a tracer 14 coacting with a templet 33 moving simultaneously with the blank, compensating means are provided for the cutting of cams adapted to be used with followers mounted on radius arms, such means comprising an auxiliary templet 48, representing the arcuate path of the cam follower, and coacting with an auxiliary tracer 46. The cutter spindle 4 which is axially adjustable by rack and pinion mechanism 6 is driven from an electric motor 13 through change gears 7 .. 12. The tracer 14 is mounted in the same vertical plane as the cutter while the templet and work are mounted on a table 20 which is adjusted longitudinally by a screw 21 and is moved transversely for the copying movement by a screw 19 operated by a motor 19a under the control of electromagnetic clutches as described in the above mentioned Specification. The cam blank spindle 24 is driven through gearing from a motor 31a under electromagnetic clutch control, and a gear 37 on the blank spindle operates a rack connected to the templet 33, the edge of which represents a straight line development of the cam path to be cut. The bracket 22 carrying the cam blank and templet may be rotated through 90‹ for the cutting of a drum cam such as 25D, Fig. 3. The tracer is preferably of the kind having a knife edge located on the axis of the tracer. To provide the necessary compensation for the movement of a follower 56 mounted on a radius arm and moving over the arcuate path 57, the cutter spindle with its drive gears and motor is mounted to move vertically on ways 38 and is moved so that relatively to the blank, the cutter moves over the same arcuate path as the follower roller 56. For this purpose an auxiliary templet 48 representing the follower path 57 is adjustably mounted on the slide 20 and co-operates with a tracer 46 controlling through electromagnetic clutches 43, the drive from an independent motor 45 to a spindle 40 imparting vertical movement to the cutter carriage. The tracer 46 is fixed in relation to the cutter. In the wiring connections, Fig. 5, for the auxiliary tracer, which is substantially the same as that described in Specification 297,263, [Class 83 (iii), Metals, Cutting], the front contacts 62 act through relay 66 to operate an armature bar 67 thus closing the circuit (110 volts) of electromagnetic clutch S while the back contacts 63 act through relay 72, armature bar 73, and contact 74 to close the circuit of electromagnetic clutch N. A switch 86 in these circuits is interconnected with a switch 81 in the circuit of a low potential generator 83.

Title: Methods and apparatus for determining the distance travelled by vehicle with respect to a reference surface making use of the doppler effect
IPC: G01S15/00
Filed: 1971-08-05
Abstract: 1334585 Doppler navigation system INSTITUT FRANCAIS DU PETROLE DES CARBURANTS ET LUBRIFIANTS 5 Aug 1971 [13 Aug 1970] 36897/71 Heading H4D A method of determining the distance travelled by a vessel comprises, transmitting acoustic signals intermittently along an inclined direction to a submerged surface, detecting reflections during interruption of the transmitted signals, determining the time difference between a predetermined number of cycles of reflected signals and of reference signals, computing therefrom the distance travelled and maintaining the mean recurrence period of the transmissions constant over a predetermined whole number of periods. In the transmitter, Fig. 4, a modulator 3 passes measuring signals of frequency F 0  for a time period 8 and echo sounding pulses of frequency F 1  during the interruptions thereof. The signals are radiated from three transducers 5a-5c along three edges of a pyramid arranged to provide measurement of movement along orthogonal directions (Fig. 3, not shown). In the receiver (Fig. 5) during the interruption periods, pulses of frequency 2<SP>n</SP>F 0  are counted in meters 8a-8c for a given number of cycles, N<SP>1</SP>, received from each transducer. The three counts N 1 , N 2 , N 3  are combined in summing units 10, 11 when gates 9a- 9c are enabled by synchronizer 1. At a further command FS from synchronizer 1 the values of N 2  - N 1 , and N 3  - N 1 , which are proportional to the longitudinal and transverse movement of the ship during one transmitter cycle, are transferred to displays 12, 13 calibrated in distance. If the sea depth is such that the echo pulses do not arrive until the measuring interval has begun, i.e. the echo sounding pulses coincide with the interruption period several modifications are described (i) The measurement may be interpolated from the last valid measurement until the depth recedes. (ii) The transmission period may be lengthened to enable measurement to take place and shortened in the succeeding period to ensure a constant mean period. (iii) Extra interruption periods are provided during each cycle that the critical depth is encountered such that measurements may be performed on undisturbed portions of the echo signal. The period of these extra interruptions is varied. The Specification also provides detailed description of the synchronizer which provides control signals for the system and incorporates a manual facility for varying the transmitter repetition frequency to provide increased resolution if necessary.

Title: Improvements relating to elastic fluid turbo machines such as steam turbines and aircompressors
Inventor: CRANG TERENCE FURSDON
IPC: F01D25/16
Filed: 1955-12-28
Abstract: 817,897. Fluid bearings. WHITE & CO. Ltd., J. S. Dec. 20, 1956 [Dec. 28, 1955], No. 37152/55. Class 12 (1). [Also in Group XXVI] In an elastic-fluid turbine or compressor the rotor and stator are formed so as to provide between them surfaces of substantial area which lie opposite to and close to one another and which extend both axially and radially with respect to the rotor axis. Means are provided for delivering working fluid under pressure from the high-pressure side of the machine between the pairs of surfaces so as to form therebetween a continuously flowing film of working fluid which maintains the surfaces out of contact with one another and acts as a lubricating film between the surfaces and co-operates with them wholly to support the rotor both radially and axially within the casing. The turbine rotor 9 in Fig. 1 is mounted on a shaft 13 having a portion 8 and a flange 12. The casing 1 has a cylindrical part 7 surrounding the shaft part 8 and a flange portion 11 the upper surface of which lies close to the lower surface of the rotor 9. The upper surface of the flange 12 lies close to the adjacent surface of the casing 1. Working fluid supplied through the duct 20 enters the inlet passage 5 and flows through nozzles 6 to impinge on the rotor blades 10, the working fluid then passing to exhaust through passage 3. Working fluid is tapped from the inlet duct 20 and passes through ducts 22, 19 to an annular passage 18 formed in the inner surface of the cylindrical casing portion 7. The working fluid flows in the narrow annular space between the shaft and casing portions 8, 7 and then through the narrow radial space between the flange 11 and lower surface of the rotor 9. Some fluid from the annular passage 18 also flows in the opposite direction in the annular space between the shaft and casing portions 8, 7 and then through the narrow space between the flange 12 on the shaft and the lower surface of the casing 1. In a second embodiment, the spaces between the cylindrical surfaces and between the radially-extending surfaces do not communicate directly with each other as in Fig. 1, and in this case working fluid tapped from the inlet duct is led through two separate ducts to the annular and radial passages respectively. An inward radial flow turbine is shown in Fig. 3, working fluid being supplied through duct 53 and nozzles 51 to impinge on the rotor blades 50. Working fluid is tapped from the supply duct and flows through duct 54 to the narrow radial space between the lower surface of the rotor disc 49 and the adjacent inner surface of the casing 44. This fluid then flows upwardly through the narrow annular space between the outer peripheral surface of the rotor disc 49 and the adjacent inner surface of the casing 44. The invention is also shown applied in the case of a turbine of the Francis type, the supply of working fluid being arranged. similarly to that in Fig. 3.

Title: Load-responsive pressure-proportioning valve assemblies
IPC: B60T8/18
Filed: 1975-09-10
Abstract: 1490902 Load responsive vehicle braking SUMITOMO ELECTRIC INDUSTRIES Ltd 10 Sept 1975 [11 Sept 1974] 37269/75 Heading F2F A vehicle braking system with a loadresponsive proportioning valve has a variable biasing connection to an axle 18 including a main spring 16 or 161, and an auxiliary spring 69 or 691 which comes into operation at a certain deflection of the first spring to compensate for non-linearity of the vehicle suspension. The springs may act directly on one end of a plunger 201 of a proportioning valve controlling flow between an inlet 91 and a rear brake outlet 10<SP>1</SP>, Fig. 6, or indirectly on a control valve CV, Fig. 2, between the inlet 9 and a control chamber 31 below the valve plunger 20. In Fig. 2 the proportioning valve plunger is subject to inlet pressure in the chamber 58, outlet pressure above the head 65, which abuts a seat 22, the controlled pressure in the chamber 31 and the force of a spring 37 in the chamber 31. The lower wall of the chamber 31 is preferably movable to limit pressure increases in the chamber when the control valve is shut and the plunger 20 moves down. The control valve CV comprises a differential area plunger 23 subject to front brake pressure from inlet 7 at its upper end, the spring force at its lower end and the pressure in the passages 42 and 24 on the opposing faces of the enlarged portion 62 which is abuttable with a seat 30. At low braking pressures the control valve CV remains open, the pressures in the chamber 31 and 58 are the same and the proportioning valve remains open. When the pressure rises sufficiently the valve CV closes, the pressure in the chamber 31 remains substantially constant and the plunger 20 provides an output pressure increasing at a lower rate than the input pressure. As the vehicle load is increased the upward force on the plunger 23 increases to delay closing of the valve CV and the onset of the proportioning valve action. Should the front brake line fail, the lack of pressure on the upper end 63 of the plunger 23 delays closing of the control valve to give full rear braking. The spring support 53 may alternatively be displaceable by a piston responsive to vehicle suspension hydraulic pressure supporting the platform instead of to the beam 55.
