Abstract: 1535722 Power steering systems ADWEST ENG Ltd 3 Nov 1975 [6 Aug 1974] 34640/74 Heading B7H A rotary valve, particularly for use in a rack- and-pinion power-assisted steering system, comprises a valve sleeve 5 and a relatively rotatable hollow valve rotor 6 each having axial grooves 5b, 5d and 17, 20 for controlling fluid flow, the rotor having a radial passage 19 connecting its interior 18 to an outlet port 3, and at least one of the rotor grooves 20 being connected to its interior 18 by a restricting passage 21, which passage acts to create a back pressure and reduce valve noise. The sleeve 5 has annular grooves 12, 13, 14 separated by seals 22-25 grooves 12 and 14 being connected to opposite sides of a working cylinder and groove 13 communicating with an inlet 2. Groove 12 is connected to axial grooves 5b by passages 5a and groove 14 to grooves 5d by passages 5c whilst groove 13 is connected to grooves 17 of the rotor by passages 16. With the rotor biased to the null state by torsion rod 8 fluid from inlet 2 passes to groove 13 and then via passages 16, grooves 17, grooves 5b, 5d, grooves 20, and passages 21 to the rotor interior and finally via passage 19 to outlet 3. As the rotor is rotated, say clockwise (Fig. 3, not shown), communication between grooves 17 and 5d and between grooves 20 and 5b is cut off so fluid flows from inlet 2 to one side of the working cylinder via groove 13, passages 16, grooves 17 and 5b and passages 5a and fluid is exhausted from the other side via passages 5c, grooves 5d and 20, passages 21, the rotor interior 18 and passage 19.

Filed: 1947-12-30
Abstract: 647,974. Telegraph exchange systems. STAATSBEDRIJF DER POSTERIJEN TELEGRAFIE EN TELEFONIE. Dec. 30, 1947, No. 34838. Convention date, March 19, 1943. [Class 40 (iii)] In a substation circuit, the switching on and off of the teleprinter is controlled by separate non-polarized relays associated with rectifiers and responsive to the direction of current in the subscriber's line. In one embodiment shown as applied to an automatic exchange, calling key OT operates relays A, LR. When the calling line has been found (or a call comes in), reversal of current at the exchange operates relay B over rectifier S2 and an alternating-current relay H operates to switch-on the teleprinter. motor M. Relay B is short-circuited by rectifier S3 and releases. If the call is terminated from the exchange by a further reversal of current, relay C operates over the winding no longer effectively short-circuited by rectifier S3 and releases relay H. If the call is terminated at the substation by operating key ST, another winding of relay C is connected across the line in series with rectifier S4 which blocks the current to the exchange to give a release signal. Reversal of the current in the loop then operates relay C over this winding. In a modification, Fig. 2 (not shown), relay C has only one winding and one rectifier performs the functions of rectifiers S2 ... S4 of Fig. 1. Specification 370,551, [Group XL], is referred to.

Abstract: 936,206. Printing processes &c. W. R. GRACE & CO. Oct. 15, 1959 [Oct. 16, 1958; Sept. 28, 1959], No. 35007/59. Drawings to Specification. Class 100 (2). [Also in Group VIII] A lithographic printing blanket has a firmness such that a pressure of at least 15 lb. per square inch must be exerted on it to reduce its initial thickness by 2 mils and a compressibility such that the additional pressure required to reduce the thickness of the blanket by 2 mils more is not more than 35 lb. per square inch. The blanket comprises a non-extensible backing, a compressible body portion, and a thin ink-transfer surface. The backing may be prestretched cotton duck fabric, several plies bonded together with neoprene latex, or a thin sheet of aluminium, stainless steel or a polyester resin, or the offset cylinder can be used as the backing. The compressible body may be a fibre paper comprising 70% mercerized cotton linters and 30% short paper fibres impregnated with rubber, e.g. rubber latex to the extent of 72% of the fibres, a mixture of 80% of a butadiene-acrylonitrile polymer latex and 20% solution of phenolic resin, to 60%, or " Buna-N " Latex (Registered Trade Mark) to 72%. The body is secured to the base with a butadiene-acrylonitrile copolymer latex and press-cured at 250 F. for 20 minutes or cured in a hot-air oven. The compressibility of the body is caused by small voids occupying 49-75% by volume. The ink-transfer layer may be a polyurethane elastomer cement, or a butadiene-acrylonitrile copolymer latex compound. Alternatively, the body may be used as a replacement portion of the blanket, being cured and having the transfer layer on one face and adhesive on the other, covered with silicone-treated paper until required. A worn-out body is detached from the base and replaced. In order that the blanket should have the required firmness and compressibility, the body alone should require at least 10 lb./square inch for 2 mils compression, and not more than 60 for further compression to 4 mils.

Abstract: 826,686. Gas turbine plant. ROVER CO. Ltd. Nov. 7, 1957 [Nov. 22, 1956], No. 35712/56. Class 110 (3). [Also in Groups XI and XII] A gas turbine engine fuel system includes a fuel pump, means for controlling the maximum speed of the engine, and a fuel burner to which is delivered the effective pump output for combustion in a combustion chamber of the engine. Means is also provided for delivering to the burner a supply of primary oxidizer which for normal running is in the form of air from a zone of a compressor, of the engine, which is at a higher pressure than the main combustion air, and for starting the engine is in the form of oxygen under pressure from a reservoir. The equipment shown comprises a combustion chamber A, fuel pump B, oxygen bottle C and a control valve D. The combustion chamber comprises an outer casing 11 and an inner flame tube 12, the latter comprising an intermediate Venturi-shaped portion 17a, 17b and an outlet portion 18. Air from the engine compressor is supplied through openings 22 to the space between the flame tube and the outer casing, combustion air entering the flame tube through the ducts 21, dilution air through the openings 23 and cooling air through the small orifices 24 in the end wall of the flame tube. The fuel burner 42 projects into the flame tube and supplies fuel and oxidizer as indicated at 56. Fuel is supplied to the burner by means of the pump B which comprises a rotor 25 carrying reciprocating plungers, the fuel entering at 34 and discharging through duct 35 and line 39 to the burner duct 40. The fuel pump rotor 25 carries a centrifugally-operating valve 36 as described in Specification 819,463, [Groups XXVII and XXVIII], so that when the turbine tends to over-speed, the valve opens and fuel is by-passed back to the pump inlet. The valve D is shown in the starting position in which oxygen from the bottle 64 flows through the duct 58 to the burner duct 42 around the fuel duct 40, the oxygen discharging from the burner with the fuel as shown at 56. For normal running, the valve D is moved so that air under a pressure greater than that of the normal combustion air is supplied through ducts 66 and 58, the valve D being operated either manually or automatically. The burner nozzle is shown in Fig. 2, fuel supplied through the duct 40, passing through swirl holes 49 to the interior of the nozzle 48 and discharging therefrom in an upstream direction. Air or oxygen as the case may be flows through the annular passage between the duct 40 and the outer wall 42 and then through inclined duets 55 in the nozzle ring 52 so that the swirl of air or oxygen mixes with the fuel issuing through nozzle 48.

A signal from electrodes 1 passes through amplifier 2, rectifier 3 and integrator 4. The integrated output from 4 is added to a constant frequency sawtooth voltage from generator 20 and fed to a Schmitt trigger 5 which operates electronic switches 8, 9 to connect motor 10 to a source B<SP>+</SP>. Alternatively, similar circuitry from a second myoelectric voltage source 1a applies voltage of opposite polarity to motor 10 via electronic switches 11, 12. The sources 1, 1a are respectively associated with the hand opening and closing muscles, for example. The braking circuit 13 comprises an amplifier 14, an integrator 15 and a differentiator 16 the output of which is proportional to the rate of change of the pulse duty factor of trigger 5 or 5a. An amplifier 17 contains a transistor (T2, Fig. 2, not shown) which is biased so as to become conductive only above a threshold value of one polarity of the output signal of differentiator 16. The output of amplifier 17 intermittently closes switches 9, 11 to short circuit the armature of the motor.
