Patent GB-1373196-A (GB)
Title: Tandem spring and service brake actuator
IPC: F16D65/28
Filed: 1973-03-21
Abstract: 1373196 Tandem spring and service brake actuators BENDIX CORP 21 March 1973 [3 April 1972] 13629/73 Heading F2F A tandem spring and service brake actuator comprises a service actuator part 14 and a spring actuator part 16 separated by a central wall 12, the service actuator part 14 having a service pressure chamber 18 and the spring actuator part 16 having a spring chamber 40 and a control cavity 36 separated by a piston 34, the actuator including a first valve 66 which allows connection of the spring chamber 40 and the service chamber 18 during spring-actuated brake applying movement of the piston 34 and also a second valve 78 for connecting the spring chamber 40 and the control cavity 36 when fluid pressure is applied to the cavity 36 to compress the spring 42 and release the brake. As shown in Fig. 1, the valve 66 is carried by a sleeve 44 integral with piston 34 and comprises a valve head 68 positioned within a valve cavity 70, and secured to a valve stem 72 which is provided with a spring 74 which constantly biases the head 68 into engagement with a valve seat 75. The sleeve 44 passes through a central opening 48 in the wall 12 and the opening 48 is grooved to receive 0-rings 50, 51 to seal off cavity 36 and chamber 18. In the position illustrated one or more radial holes 76 in the sleeve 44 lie between the seals 50, 51 and the chamber 40 is sealed from chamber 18. The second valve 78 is actuable to establish communication between cavity 36 and chamber 40 to allow flow of excess pressure from cavity 36 to chamber 40. During spring operation fluid pressure is released from cavity 36 and piston 34 and sleeve 44 move rightwards and holes 76 move to the right of seal 51. Surplus pressure in chamber 40 opens valve 66 and this pressure will flow to chamber 18 via ports 60 in a rearward extension of sleeve 44, a passage 56 between sleeve 44 and a fixed sleeve 52, a cavity 58, valve 66, cavity 70 and holes 76; when this pressure is dissipated to atmosphere via a brake valve the valve 66 closes. During release of spring application, residual pressure in chamber 40 will flow to chamber 18 until holes 76 are positioned between seals 50, 51, but thereafter any excess of pressure in cavity 36 causes opening of valve 78. In the modification of Fig. 2 seal 51 is omitted and a rolling diaphragm 83 replaces seal 50; the diaphragm 83 co-operates with holes 86 in sleeve 44.

Title: A method for treating fabrics
Inventor: SMITH CHRISTOPHER WILLIAM BLEW
IPC: D06C7/02
Filed: 1960-04-20
Abstract: <PICT:0932403/IV(a)/1> Fabrics are shrunk or relaxed by immersing the fabric at full width, while unsupported and under conditions allowing it to shrink, in a hot aqueous liquid and subsequently removing the fabric from the liquid supported on a conveyer belt which dips below the surface of the liquid.  The process is applicable to any fabrics comprised of fibres possessing potential shrinkage or which can be relaxed by hot aqueous treatment, e.g. polyacrylonitrile, polyolefines or copolymers of vinyl chloride and vinyl acetate.  The hot aqueous liquid may be hot water containing a soap or wetting agent, or containing other additives such as a dye.  The temperature of the liquid must be sufficient to cause relaxation, e.g. for polyacrylonitrile, above 75 DEG C. In the described embodiment a fabric 1 is fed by rollers 2 on to stainless steel shoot 3, down which it slides into bath 4, containing liquid.  The fabric flows along the surface of the liquid, assisted by paddles 5, and is removed from the bath by conveyer 6.  Cooling is assisted by cold water spray 7.  Final cooling takes place in cold water bath 8, from which the fabric is withdrawn by rollers 9.  In an example, a polyacrylonitrile fabric is relaxed, as above, in water at 90 DEG C. containing 1% of wetting agent.ALSO:<FORM:0932403/IV(a)/1> Fabrics are shrunk or relaxed by treatment with hot aqueous liquid in the manner shown.  Fabric 1 is fed by rollers 2 on to a stainless steel shoot 3, down which it slides into a bath 4, containing hot aqueous liquid, e.g. water at 90 DEG C. containing 1% of wetting agent.  The fabric flows along the surface of the liquid, its movement being assisted by paddles 5.  The fabric is led from the bath by means of conveyer belt 6, the leading edge of which dips below the surface of the liquid in bath 4.  Cooling of the fabric on the belt is assisted by cold water from jet 7. Final cooling is carried out in cold water bath 8 from which the fabric is withdrawn by rollers 9.

Abstract: 452,109. Photo-electric cells. TURNER, F. S., 2576, Green Street, San Francisco, U.S.A. Feb. 15, 1935, No. 13788/36. Divided out of 452,037. [Class 39 (i)] In a photo-electric tube for use in the dissection of an optical image in television transmission, the electrodes within the tube consists solely of a photo-sensitive cathode 24 and a pair of anodes 25, 29 one surrounding the other and having an aperture 27 directed towards the cathode. An optical image is focused by means such as the lens 35 on the cathode, the emitted electrons being influenced by a focusing coil 41 and scanning coils 36, 39, so that in sequence a direct beam from every part of the cathode is caused to enter the aperture and fall on the inner selecting anode 29. This may give directly the desired signals through an insulated connection 31 ; or secondary emission may be obtained by the impact of the electrons on the inner anode, these secondaries being collected by the outer anode which then is included in the signal circuit. The beam during scanning will be crowded up against the wall 11 of the tube, the wall being charged thereby at a constant potential. The inner anode, which is at a potential different from the outer, is supported by an insulator 30 ; the lead 31 is screened by a tube 34 to which the outer anode lead is connected. The cathode consists of caesium deposited on a layer of silver carried by a mirror 14, the silver layer being connected to the cathode lead 21 by clips which hold the mirror on a plate 15.

Title: Manufacture of substituted carboxylic acid amides
IPC: C07D215/16
Filed: 1931-05-11
Abstract: Carboxylic acid amides containing aminoalkyl residues in the amide group are prepared by interaction of an aminoalcohol ester, e.g. the halide or aryl sulphonic ester, with a metal derivative of a carboxylic acid amide of the formula <FORM:0368590/IV/1> wherein R and R1 represent hydrogen or an aliphatic, aromatic, or heterocyclic residue, or in which R has the foregoing meaning and R1 stands for aryl.  The metal derivatives are obtained by treating the amide with a reactive metal or an amide, hydroxide, or alcoholate thereof. According to the examples, (1) stearic acid amide is heated with sodamide and then with chlorethyldimethylamine, yielding stearyldimethylaminoethyl-amide; (2) benzanilide, sodium ethylate, and chlorethyldiethylamine give benzoyl-N-phenyl-N-diethylaminoethylamide; (3) 2-phenyl-4-quinolinecarboxylic acid-diethylaminoethyl-amide is obtained by treating 2-phenyl-4-quinolinecarboxylic acid amide in succession with potassium amide and chlorethyldiethylamine; (4) 2-n-butyloxy-4-quinolinecarboxylic acid amide (prepared from 2-chloro-4-quinolinecarboxylic acid amide and sodium in butyl alcohol) is heated first with sodamide and then with chlorethyldiethylamine to form 2-n-butyloxy-4-quinolinecarboxylic acid diethylaminoethylamide; (5) 2-ethoxy-4-quinolinecarboxylic acid anilide (obtained from 2-chloro-4-quinolinecarboxylic acid anilide and sodium ethylate), sodamide and chlorethyldiethylamine give 2-ethoxy-4-quinolinecarboxylic acid - N - phenyl-N-diethylaminoethylamide; (6) 2-ethoxy-4-quinolinecarboxylic acid-N-benzyl-N-diethylaminoethyl-amide is obtained from 2-ethoxy-4-quinolinecarboxylic acid benzylamide, sodamide and chlorethyldiethylamine; (7) dibenzamide is heated with sodium and then with iodoethyldiethylamine to produce dibenzoyl-diethylaminoethyl-amide; (8) 2-n-butyloxy-4-quinolinecarboxylic acid amide is heated with sodamide and afterwards with bromo-ethyldiethylamine to give the same product as (4).  In like manner the following products are obtained:--stearyl-diethylaminoethyl-amide, oleyl-diethylaminoethyl-amide, 2-ethoxy-4-quinolinecarboxylic acid-N-ethyl-N-diethylaminoethyl-amide, 2-n-butyloxy-4-quinolinecarboxylic acid-b -piperidino-N-ethyl-amide, 2-ethoxy-4-quinolinecarboxylic acid-bis-(diethylaminoethyl)-amide, 2-ethoxy-6-bromo-4-quinolinecarboxylic acid-diethylaminoethyl-amide, 2-ethoxy - 4 - quinolinecarboxylic acid-diethylamino-b -propyl-amide, 2-ethoxy-4-quinolinecarboxylic acid-diethylamino-e -amyl-amide, 3-pyridinecarboxylic acid-b -piperidino-N-ethylamide, 9-acridinecarboxylic acid-diethylaminoethylamide, benzoyl-diethylaminoethyl-amide and acetyl-diethylaminoethyl-amide.
