Title: Improvements in and relating to the manufacture of tea
IPC: A23F3/06
Filed: 1932-03-31
Abstract: 385,493. Tea manufacture. McKERCHER, SIR W. G., P.O., Amguri, Sibsagar, Assam, India. March 31, 1932, No. 9241. Convention date, Dec. 9, 1931. [Class 129.] A process for manufacturing tea consists in subjecting the tea leaf after withering, with or witho u t preliminary rolling and sifting, to crushing, tearing or cutting, and curling or rolling in one operation or in a quickly applied sequence, passing the leaf through a sifter and re-treating the leaf rejected by the sifter. The leaf is then fermented, dried and stored or packed. The crushing, tearing or cutting and rolling or curling operations may be effected by the machine described in Specification 385,443. The lay-out of apparatus for carrying out the process is indicated in the Figure. The leaf from the withering sheds is passed into the rapid roller 1 where the fine tips are broken off to form fine teas. The leaf so rolled is passed through a sifter 2. Rejections from this sifter go into a second rolling machine 3 and thence to another sifter 4. The leaf from the sifters 2, 4 form the fine teas. The progress of this tea is indicated by the dotted lines. They pass through a disintegrating machine (such as described in Specification 385,443) and a sifter 6. They next pass to fermenting beds 7, 7a, to a dryer 8, a grading sifter 9 and a storage bin 10. The coarse tea takes the path indicated by the full lines. It passes through a disintegrating machine 11 to a sifter 12, and on to fermenting beds 13, 13a, a dryer 14, a grading sifter 15 and finally into storage bins 16, 17, 18, according to grade.

Title: Improvements in reciprocating pumps including an auxiliary piston, in particular for the injection of fuel into internal combustion engines
IPC: F02M59/32
Filed: 1959-03-17
Abstract: 900,119. Fuel injection pumps. BESSIERE, P. E. March 17, 1959 [March 24, 1958], No. 9249/59. Class 102(1). [Also in Group XXIX]. A fuel injection pump comprises a main piston 1 which on its delivery stroke feeds fuel past non- return valve 8 to a chamber 4a and actuates an auxiliary piston 5 to delivery fuel from a chamber 4b to a conduit 12 leading to the injectors. The end of the stroke of the piston 5 is determined by the opening of a by-pass conduit 16. During the suction stroke of the piston 1 or at the end of this stroke, fuel is transferred from the chamber 4a to the chamber 4b through a conduit 9 provided with a throttled passage 10 which may be adjusted by hand or automatically. The conduit 9 is closed during the delivery stroke by the piston 1 and in the embodiment shown the piston has a quick return stroke and stays at its bottom dead centre position to provide the opening of the conduit 9 by a groove 17. In a modification as in Fig. 2 (not shown) a second groove is provided on the piston and is connected to the groove 17 by helical grooves. In this case the piston 1 is also rotated during its reciprocation such that the two parts of the conduit 9 engage a plane part of the piston during the delivery stroke but engage the grooves during the return stroke so that fuel is transferred from chamber 4a to 4b during the whole of the return stroke of the piston 1. The throttle passage may be constituted by a slide valve moved in accordance with the engine speed to vary the throttle by a gear pump actuated by the engine. The delivery from the chamber 4b is controlled in response to the engine speed by the delivery of the piston 1 which above a predetermined speed actuates the piston 5 before it has completed its return stroke

Title: Improvements in radio apparatus for indicating the distance of a remote object
IPC: G01S13/36
Filed: 1941-07-22
Abstract: 550,808. Locating objects by reflected waves. TAPP, E. T. J., BOSCH, F. J. G. VAN DEN, and VACUUM-SCIENCE PRODUCTS, Ltd. July 22, 1941, No. 9264. [Class 37] Apparatus for indicating the distance of an object comprises a radio transmitter and a receiver responsive both to a direct signal from the transmitter and to a reflected signal from the object, means for adjusting the phase relationship of the two signals at the receiver, and an indicator which indicates both the extent of the adjustment and the condition of in-phase relationship. An altimeter for an aircraft is shown in which the transmitter 10 and receiver 11 are each provided with a rotatable tuning condenser arranged to vary the tuning over a range of wavelengths between 1 and 30 metres. The condensers are rotated by a shaft 12 driven by a constant-speed motor 13. Dipole aerials 14, 15 are connected to the transmitter and receiver. The receiver is directly fed with the required strength of signal from the transmitter by a feed wire 18. The output from the receiver illuminates a lamp 22 in an indicating instrument containing a disc 20, having a hole 21, which is rotated in synchronism with the tuning condensers. Between the disc and the light source is a translucent screen 19 and in front of the disc is a scale 23 graduated in distances. The lamp is fully illuminated once in each cycle at a time when in-phase relationship exists. This point varies with the distance of the object and thus with the extent of rotation of the condensers and of the disc from a datum position, so that a point of light is seen through the hole 21 at varying positions according to the distance of the object. In a modification the tuning of the transmitter 10 and receiver 11 is pre-set and the phase relationship between the two signals at the receiver is cyclically varied by a variable coupling such as a variable impedance or Lecher wire which connects the transmitter and receiver and is driven by the motor 13.

Patent GB-788701-A (GB)
Title: Apparatus for removing the solutes from a solution by crystallisation
IPC: B01D9/00
Filed: 1956-03-28
Abstract: <PICT:0788701/III/1> Solutes are removed from a solution in a cyclonic crystallizer 1, the lower part of which, 11, is made of a yielding material, such as rubber or material with elastic properties similar to rubber.  The solution is injected by nozzles 4 into a current of air from a pipe 2, the air entering tangentially and passing downward along a helical path and leaving the cyclone by a duct 5. Crystallization occurs due to the drop in temperature of the atomized liquid, and liquid and crystals fall to the bottom.  The air current agitates the apron 11 and prevents crystals from becoming attached thereto.  The liquid and crystals flow into one or other of two tanks 11 and 111, depending on the position of a twoway valve 9. The liquid and crystals are cooled by coils 12 or 121 to cause further crystallization to take place. When the temperature is sufficiently low valve 9 and another two-way valve 15 are reversed so that the tank containing the liquid and crystals is emptied and the other tank is filled.  The liquid and crystals pass to a separator 16, such as a centrifuge, where the crystals are removed and the liquid is passed by a pipe 17 to a heat exchanger 18 through which solution is fed by a pipe 19 to nozzles 4.  The apparatus may be used to remove iron sulphate from spent pickling solution.

Title: Improvements relating to gas-cooking rings, with means for controlling gas supply by a kettle, saucepan or the like
IPC: F24C3/12
Filed: 1919-04-16
Abstract: 142,276. Towl, A. Pearce-, and Shand, J. April 16, 1919. Valves actuated indirectly.-Gas cooking-rings are provided with a valve and valve-actuating device in which the position of the utensil, such as a kettle, is arranged to turn the gas fully on or off, or to provide a partial supply of gas to the burner. To the inlet pipe f is secured a boss g surrounded by a rotatable sleeve h, the members g, h being provided with corresponding holes which may be moved into and out of register when the sleeve h is suitably rotated. The gassupply holes are normally kept out of register by an eccentrically-placed weight m secured to the sleeve h; but when the kettle is placed on the stove, its edge depresses the lever t, which pushes down the stud o to rotate the sleeve h, through a spring member n, and bring the inlet holes into coincidence. The extent of the rotation of the valve member depends upon the position of the edge of the kettle relatively to the inclined edge of the lever t with which it engages. As a modification, the stud or studs o may be operated by means of rollers with cam-shaped grooves, these rollers being rotated to the extent required to actuate the valve by laterally displacing the kettle on the stove, its position determining the size of the flame.

Filed: 1968-02-29
Abstract: 1,215,546. Transmission line semi-conductor amplifiers. INTERNATIONAL BUSINESS MACHINES CORP. 29 Feb., 1968 [3 March, 1967], No. 9738/68. Heading H3T. [Also in Division H1] In a transmission line amplifier having elongated conductors extending side by side on a semi-conductor substrate and forming therewith the amplifying element the amount per unit length of one of the characteristic parameters of one or both conductors varies along the length of the conductors. The amplifying element may be a field effect transistor with a Schottky barrier gate electrode, or a bipolar diffused transistor, the electrodes in each case being in the form of parallel strips overlain by a dielectric or magnetic material arranged to give a varying capacitance or inductance unit length. A third embodiment (Fig. 3) utilizes a field effect transistor in which the channel is in the form of a long strip or series of rods 15 extending between source and drain regions 16 through the dielectric or magnetic material 14. It is also possible to use a plurality of similar amplifying elements formed in a common semiconductor body or in separate bodies disposed on a common substrate. In this case elements are interconnected by passive line section and the transconductance is varied by working the elements on different parts of their characteristics. In a preferred arrangement the transconductance is arranged to approach zero at each end of the line which has matched terminations constituted by ohmic resistors. The theory of the amplifier performance is discussed in detail.

Title: Improvements in or relating to damping arrangements for vehicle suspension systems
IPC: F16F9/26
Filed: 1944-05-22
Abstract: 575,497. Shock-absorbers. PETRIE, J. A. May 22, 1944, No. 9857. [Class 108 (iii)] In a shock-absorber for vehicles or aircraft of the piston-and-cylinder type in which flow of fluid through a conduit connecting the ends of the cylinder is controlled by a damping valve, means are provided for applying a closing load to the valve, means for progressively unloading the valve down to a predetermined degree, and means responsive to vehicle shocks, caused by travel over major irregularities, for progressively restoring the closing load to an appropriate degree. The double-acting shockabsorber shown comprises two main cylinders 10, 11, in which pistons 12, 13 are reciprocated by a rock arm 14 to force liquid through a conduit 15 controlled by a damping valve 18, the space in the casing above and around the cylinders constituting a reservoir for liquid which is drawn upon automatically through valves 15, 17. The valve 18, which has a port 25 closable by a spring-pressed non-return valve 26, is urged towards closing position by springs 19, 20, which apply maximum load to the valve 18 when the vehicle is at rest, spring 19 being enclosed in a flanged shell 21 and spring 20 acting against a controlling piston 22 which bears on the flange on shell 21 and moves in a cylinder 23 having a port 24. One end of valve 18 is exposed to pressure on the cylinder 11 and an annular shoulder on the valve is exposed to the pressure in conduit 15 and thus in cylinder 10. Above cylinder 23 is another cylinder 27 which communicates by a passage 28 with the reservoir and has a central stem 29 containing a passage 30 connecting the cylinders 23, 27. An inertia weight 31 guided on the stem 29 is screwed to the upper end of a spill valve 32 which is normally maintained in a position closing the passage 30 by a spring 33 acting on the weight 31. Operation.-Any upward movement of the axle causes liquid to be pumped past the non- return valve 26, displacing piston 22 against spring 20 and thus relieving the spring pressure on the valve 18. Piston 22 may be displaced into a position in which the port 24 is uncovered and may remain thus, in the position of maximum softness of damping, allowing excess liquid to pass back to the reservoir. When axle movements are violent enough or of sufficient frequency to build up appreciable disturbances in the chassis, the spill valve 32 is opened by relative movement between the chassis and inertia weight and oil is discharged from cylinder 23 through passage 30 back to the reservoir, thus allowing the spring pressure to build up again on the damping valve 18. The spill valve 32 is so designed that, above a predetermined disturbance of the chassis, it spills oil faster than the non-return valve 26 can supply it so that the maximum spring load is applied to valve 18 and maximum damping is effective. An additional control 34 for the springs 19, 20 controls the maximum resistance of valve 18.

The booth has vertical casings 1 and 2 and a bridging section 3.  Within each vertical casing is a spray chamber 4.  The common ceiling stretching across the full width of the spray booth has openings for the entry of clean replacement air from filters 38 and blowers 39.  Within each chamber 4 is an operator's platform 10.  The platform is raised or lowered by a <PICT:0706600/III/1> tackle block 15 joined by a cable 16 to a hoist motor fixed to the underside of the roof of the booth, and is motivated by the operator.  In the rear corners of the chamber are stationary light casings 22 to illuminate the surface being sprayed.  On the inner side 6 of each chamber 4 are exhaust outlets 23 and 24 through which the spray fumes are drawn to compartments 25 where the air is washed by water sprays.  The air is withdrawn from the compartments 25 by fans 27 into a centrally located vertical outlet, and thence to a stationary duct 30.  The stationary duct 30 has tiltable vanes on its underside, those immediately above the vertical outlet being opened by cams on the outlet so that the air enters the duct 30, and is then withdrawn through a stack 34 and a connecting duct 35 into a blower 36.  The booth is propelled by an electric motor 43 driving one of its wheels.  The booth travels the length of the coach being sprayed, its speed and direction being controlled from one of the spray platforms.  In a modification the both is suspended from rollers riding on ceiling beams.
