Title: Improvements in or relating to the printing and dyeing of pile fabric
IPC: B41F1/40
Filed: 1957-11-01
Abstract: 868,416. Printing on pile fabrics. C.S.C.M. Ltd. Nov. 1,1957 [Aug. 13, 1957], No. 29552/60. Divided out of 868,415. Class 100(2) Pile fabric is printed by passing it under a pressure roller which presses the pile face of the fabric downwardly against a printing surface on a roller, or endless belt, this surface comprising a number of receptacles each having a thin upstanding wall with free edges so that an area of the pile enters the receptacle and is separated from the remainder, and each receptacle before the pile is compressed into it is supplied with a controlled quantity of colouring agent. As shown in Fig. 1, carpeting 138 is fed with its pile downward over a roller 134 and beneath a pressure roller 139, the surface of the roller 134 comprising upstanding rubber walls defining colour receptacles. The printing roller 134 is partially immersed in a colour container 135, an adjustible doctor blade 137 scrapes off excess colour, and the walls of the receptacles are compressed by a resilient roller 140 before they enter the liquid colour to expel the air from the receptacles. In a modification, immediately after the walls of the receptacles have been compressed by a resilient roller, colour is poured into the receptacles on the roller from a nozzle, and a doctor blade scrapes off excess colour before the receptacles reach the carpeting. In Fig. 4 the printing roller is replaced by an endless belt 146, the colour receptacles provided on the belt being filled with colour from a container formed by a doctor blade 161 and an air-expelling roller 162. Colour is supplied from a pipe 159, and this may be removed when desired by a suction tube 160. The belt 146 is mounted on rollers 148, 149 and supported by a stand 147 and idler roller 157. The carpeting 150 is led from a roller 151, over a roller 152, under a pressure roller 153, and over a pin roller 154 to a take-up roller 155. After printing on the carpeting, the belt is sprayed with water from a pipe 164 in a washing chamber and then dried by air from a pipe 165, so that the receptacles are clean and ready to receive a new charge of different colouring agent if desired.

Title: Stabilized signal amplifier embodying semi-conductor devices
IPC: H03F3/30
Filed: 1953-10-26
Abstract: 744,436. Transistor amplifying circuits. RADIO CORPORATION OF AMERICA. Oct. 26, 1953 [Nov. 15, 1952], No. 29587/53. Class 40 (6). In an amplifier, two semi-conductor devices of opposite conductivity type fed in parallel are arranged so that means responsive to a difference in operating characteristics causes a change in the operating bias in a sense to reduce the difference. An amplifier, Fig. 1, of the type described in Specification 736,063 feeds a load Z, the input being applied in parallel to complementary transistors 10, 11 to produce additive A.C. collector currents in the load. The base resistors 24, 25 are returned to a point A on the load Z having a resistive component to earth. In the absence of a signal, any variation of characteristic tending to make point B positive will raise the potential of point A, and hence that of the base electrodes of the transistors. The collector current of transistor 10 will therefore be reduced and that of transistor 11 increased so that point B is brought nearer earth potential. In a modification, Fig. 2, the circuit operates in class B, transistors 30, 10 and 31, 11 conducting on successive halfcycles. The load Z may' be a loud-speaker voice coil or the deflection coils of a C.R.T., Fig. 3 (not shown), and may take other forms to give the amplifier various characteristics. The selected load is arranged to have a suitable resistive component to earth. With the components of Fig. 5, feedback voltage is proportional to output current or the first derivative of the current if the circuit of Fig. 6 is employed. The circuit of Fig. 7 provides feedback only at the resonant frequency of the tuned circuit 50, 51 so the amplifier rejects this frequency. With the resistor 49 and tuned circuit 50, 51 interchanged, Fig. 8 (not shown), the amplifier is selective and gives high gain only at this frequency.

Title: Improvements in or relating to the combustion chambers of internal combustion engines, and means for supplying the charge thereto
IPC: F02B75/22
Filed: 1938-10-13
Abstract: 518,856. Cylinders; regulating. PESCARA, R. P. Oct. 13, 1938. No. 29677. Convention date. Oct. 15, 1937. [Classes 7 (ii), 7 (iii) and 7 (vi)] A combustion chamber, substantially restricted to a side pocket 3, has two side admission valves 4 and a single overhead exhaust valve 5 which is arranged, either partially over the cylinder bore, as shown, or over the inlet valves. The admission valves may be of different size and fed by separate induction pipes leading from different carburetter choke tubes and throttle valves, the smaller only being in use at low speeds. The throttle valves are either connected for operation in succession from a single accelerator pedal, or connected to a centrifugal speed governor with a spring-controlledfollow-up device controlling the larger throttle. The two admission valves may be actuated by a single rocker, and in a V engine a single camshaft, arranged at the base of the V, actuates similar valves in the two cylinders. The piping may be so arranged that the pipe supplying the smaller valve is more intensely heated by the exhaust than that supplying the larger valve. The Specification as open to inspection under Sect. 91 comprises also two' overhead exhaust valves 5 ; the arrangement of the valves may be interchanged, or the pair of admission valves may,comprise one side, and one overhead valve. This subject-matter does not appear in the Specification as accepted.
Patent GB-304406-A (GB)
Title: Improvements in the steering mechanism of power propelled road vehicles
IPC: B62D7/22
Filed: 1927-11-07
Abstract: 304,406. Lanchester, F. W., and Lanchester's Laboratories, Ltd. Nov. 7, 1927. Non - reactive steering - mechanism.-A liquid damping-device coupled to the steering mechanism of a motor vehicle is furnished with electricallycontrolled relief valves which permit free operation by the steering handwheel. In the construction of damper shown in Fig. 2, a radial partition B connected to the steering mechanism oscillates in a segmental chamber A which it divides into two parts, a section through one of the parts being shown in Fig. 3. Each part communicates independently with a reservoir C by a one-way valve L and by an electrically-controlled valve J. The one-way valve supplies liquid to the operating chamber while the valve J is normally held closed by a lever G<1> operated by an electromagnet. When the steering hand-wheel is turned in either direction, one of the electromagnets is de-energized so that the corresponding valve is left free to open and the damper then exerts no resistance to movement in that direction. A certain amount of leakage is permitted independently of the valves L, J so that the apparatus functions as a damper and not as a lock. The electromagnets are controlled by switches which are actuated by a small amount of lost movement between the steering hand-wheel and the steering column. The handwheel is pivoted on a bracket P, Figs. 4 and 5, fixed to the steering column P1 and carries a pin O1 which carries, but is insulated from, a block R having a small amount of movement between the flanges T1 of bushes T2 supported through insulating material in the bracket P. The electromagnets are connected by insulated wires to washers W, W2 which are in contact with the bushes T2, and the block R is electrically connected to an accumulator or other source of electricity. When the steering handwheel is inoperative, the spring-pressed studs S1, S2 keep the circuits through both electromagnets closed, but when the hand-wheel is turned, one or the other of the studs, S1, S2 fails to contact with the block R; the corresponding electromagnet and valve are therefore released. The magnetic control of the valves may be reversed so that they are held closed by a spring and are opened electrically when the hand-wheel is operated.

Title: Improvements in or relating to a container
IPC: A61J1/00
Filed: 1948-11-16
Abstract: 648,522. Stoppers. STEVENS, A. H. (Baxter Laboratories, Inc.). Nov. 16, 1948, No. 29771. [Class 125(iii)] A closure for a container for use, more particularly, in the withdrawal and dispensing of blood and blood portions, consists of a rubber or like plug B with three passages 11, 12, 25, the two former being blocked by thin diaphragms 13, 16 and the latter by a thick upper wall 25a. The plug B is placed loosely in the neck of the container which is then evacuated, the plug being finally seated by a sudden change to atmospheric pressure or by being pressed into the container neck. The plug is then protected by a resilient sealing disc 22 and cap 23. When the container is to be filled with blood, a hypodermic needle 26 is thrust through the thick part 25a and blood is drawn by the vacuum through the tube 28 in the container. The wall separating the passage 25 and one, or each, of the passages 11, 12 is thin and resilient, so that when the needle 26 presses down the part 25a, the wall of the passage 25 flexes into the adjacent passage or passages. This ensures that, when the needle 26 is withdrawn, the punctured part of the plug is self-sealing. When the blood is to be dispensed, the cap 23 and disc 22 are removed, the head 20a of a fitting 19 is pressed through the thin diaphragm 13, and a hypodermic needle 17 is inserted through the diaphragm 16 to act as an air inlet. The punctured diaphragm grips the tapered part of the fitting 19 and tends to move the fitting outwardly so that the head 20a seals against the shoulder 13a. The positions of the passages 11, 12 are indicated by depressions 14, 15 in the top of the plug, and the axis of the passage 25 is indicated by a mark on the top of the plug.

Abstract: 261,914. Bonnet, (nÚe Monet), C., Bonnet, G., and Bonnet, F., (trading as Bonnet, AinÚ, et ses Fils, Veuve). Nov. 26, 1925. Reversing gearing for mercerizing-machines of the kind in which a double clutch 1 is thrown alternately into engagement with oppositely rotating driving-members 3, 4 is controlled automatically through a rotating cam 9 by a lever 13 weighted at its upper end 14. The lever 13 is pivoted at its lower end 15 upon a carriage 16 slidable upon guides 17, and the cam acts to throw the carriage from side to side to effect a quick throw-over of the clutch 1. A lever 19 for this purpose connects a bowl 20 engaging the power cam with a slot 21 in the carriage. The upper end of the lever 13 has a slotted connection 12 with a lever 10, which through a shaft 8 and linkage 5, 6, 7 controls the clutch 1. To effect a more positive throw-over, the upper end of the weighted lever may be thrown in the opposite direction to the carriage by the cam, a bowl 11 making connection for the purpose. The cam 9 may have a portion shaped to hold the weighted lever vertical to stop the machine.

Title: Improvements relating to the treatment of raw materials suitable for use in the manufacture of cement and other products
IPC: C04B7/40
Filed: 1939-11-16
Abstract: 536,586. Preparing raw materials for the manufacture of cement &c. JORGENSEN, M. VOGEL-. Nov. 16. 1939, No. 30231. [Class 59] [Also in Group XIX] In the preparation of raw materials for use in the manufacture of cement, lime, &c., wherein the raw material in the form of a slurry is ground &c. and thereafter separated in a centrifugal separator into a fine fraction and a coarse fraction as described in Specification 384,736, the water content of the raw slurry being fed to the separator is kept suffciently low so as to obtain the fine fraction as a viscous slurry of low water content. The coarse fraction is obtained as a cake or highly viscous slurry and part or all is diluted with water for further treatment. The water content of the raw slurry is adjusted by determining the viscosity of samples of the fine fraction in a viscosimeter comprising an open ended tube mounted on the innermost of a number of concentric circles marked on a sheet of paper, the tube being filled with the slurry for a measurement and a measure of the viscosity being given by the number of the circle to which the slurry flows when the tube is lifted. The dimensions of the tube and diameters of the circles are specified. The raw slurry fed to a mill 2 and then preliminarily screened to remove large particles is separated into the fine and coarse fractions 4, 5 respectively in the centrifugal separator 3. and the coarse fraction diluted with water at 6 is then subjected to screening, centrifuging or treated in a hydraulic classifier 7 to give a coarse fraction 8 which may be further ground or wasted and a fine fraction 9 which is returned to the mill. The fine fraction may be passed to an additional centrifugal separator and the coarse fraction therefrom treated as before. The coarse fractions may be treated in secondary mills and then centrifuged, the fine fractions being returned as before; one or more of these fractions may be mixed with the fine slurry from the first centrifugal separator and the mixed slurry then treated in a second centrifugal separator. The separating and grinding stages and the type of secondary mill used are varied according to the nature of the components of the raw material. The process is particularly applicable to materials containing a soft, finely grained component and a hard component. Specifications 479,872 and 479,891 also are referred to.
