IPC: A47J31/40
Filed: 1960-06-14
Abstract: 943,913. Tea &c. making machines. C. F. TAYLOR (METAL WORKERS) Ltd. Sept. 12, 1961 [June 14, 1960], No. 20840/60. Heading A4D. In a beverage making and dispensing machine, water permeable bags arranged in tape form and containing, for example, tea, are sequentially fed to a position where water is passed through them into a brewing chamber and subsequently re-passed outwardly therefrom through the bag. A cylindrical brewing chamber 1 has a closed upper end 2, an open lower end 3, and electric heating elements 31. It is mounted by a plate 4 on two vertical guides 5. Reversible vertical displacement of the chamber 1 is effected by a reversible electric motor 6 acting, through a reduction gear 7a, on a shaft 7a threaded extension 10 of which passes through a fixed nut 9. A spindle 12, integral with the extension 10 is fixed to the closed end 2 of the chamber 1. A solenoid operated brake is fitted to the shaft 7. A tea bag supporting band 26 is driven by feed rollers 23 and 24. In use, after a tea bag has been positioned over a support 14 with a circular aperture 13, the chamber 1 is lowered on to the tea bag and hot water is fed from a boiler through a valve controlled feed pipe 15 and hence through the tea bag in the brewing chamber 1, an air release valve connected to the tube 32 opening during the inflow. After a few seconds, a tea release valve in the tea bag support, Fig. 3 (not shown) opens and allows the brewed tea to pass back through the tea bag to a discharge pipe under the influence of the steam pressure in the chamber 1. The chamber is then raised and the exhausted tea bag is replaced by the next one on the tape as feed roller 23 is rotated to a predetermined extent by the action of recessed lower end of the link 27 on the studs 30, the upper end of the link 27 being held by a bracket 28 fixed to the spindle 12.

Acid draining from the film into tray 37 is returned to trough 33. Specifications 332,432, 322,454, 334,265, [all in Class 98 (ii)], 611,093, 611,094, 611,096 and 611,097 are referred to.
Patent GB-1342433-A (GB)
Title: Calculating machines
IPC: G06C7/08
Filed: 1971-04-19
Abstract: 1342433 "¢" key arrangements RICOH KK 19 April 1971 [4 Feb 1970] 21100/71 Heading G4B In a mechanical calculator including a number entry key representing the digit ¢, the "¢" key is locked against depression until one of the "whole number" entry keys has been depressed. The calculator shown is a modification of that described in Specification 1,055,977. Before any digit has been set up in the pin carriage 3 (Fig. 5), an operating bar 14 (Fig. 3) associated with the "¢" key is blocked by step 17B of lever 17. Setting a number into the pin carriage results in the shift of a slide 19 to the left, which rocks lever 17, to render the "¢" key operable, and shifts a slide 25 to the left, where it overlies a pivoted shoe 26 attached to the foot 6<SP>1</SP>A of the "¢" rack 6<SP>1</SP>, to prevent upward movement of the latter. Depression of the "¢" key displaces bar 14 which displaced position is held by step 21B of a spring-loaded lever 21, and a slide 16 is thus displaced to move shoe 26 out from under slide 25 and thus enable subsequent upward movement of the "¢" rack 6A. Depression of the "¢" key does not result in the setting of a pin in the pin carriage 3. During a subsequent calculating operation, upward movement of the "whole number" racks 6 (Fig. 5) is arrested by set pins 4 in the normal way, whereas upward movement of the "¢" rack 6<SP>1</SP> is arrested by a fixed stop (31, Fig. 4, not shown), the height of which corresponds to that of the pins 4 representing digit "5". Slides 19 and 25 are restored to their Fig. 3 positions by means not shown during printing. Lever 21 and hence bar 14, slide 16 and lever 17 are restored to their original positions by a bar 23 which is shifted when any number key other than the "¢" key is depressed, to trip lever 21. In the Fig. 3, position, a recess 25B in slide 25 allows passage of shoe 26 when rack 6<SP>1</SP> rises during a totalling or subtotalling operation and the accumulator (not shown) contains the digit "¢".

Abstract: 466,993. Excavators. MENCK & HAMBROCK GES. July 30, 1936, No. 21105. Convention date, Sept. 7, 1935. [Class 68 (i)] An excavator of the shovel, grab, or like type is convertible into a bucket wheel excavator, the bucket wheel and conveyers being driven from the drum which normally lifts the shovel &c. and being lifted or lowered by means of the other drum or drums. In Fig. 2, the normal boom is replaced by a boom 5 carrying the bucket wheel 7 and conveyer 25 which are driven from the drum 14 through bevel gears 18, sliding or telescopic shaft 15 and further bevel gears. Alternatively, the drive may be effected by a chain with idlers to take up slack caused by lifting or lowering the boom by rope 8, or it may be effected through bevel gearing or chains to the fulcrum 4 of the boom and thence to the bucket wheel &c. The conveyer dumps into wagons 26 or on to a further conveyer. In Fig. 3, the bucket wheel is carried by an arm 22 pivoted at 20 to the boom 19 which may be bent with the lower arm horizontal. The arm 22 is adjusted by rope 23 and the boom by cable 21 ; by co-ordinating the gearing between the drums 13, 14, or varying the number of turns of the ropes or their connection to the arm 22 and boom 19, the bucket wheel may be made to cut any desired curve or line.

Filed: 1946-07-16
Abstract: 615,689. Gas turbine plant. BALLANTYNE, D. H. July 16, 1946, No. 21304. [Class 110 (iii)] A working fluid used only for starting a gasturbine power plant is provided by the burning of a slow-burning explosive, as cordito, or by a reduction process in which the decomposition of a solid or of a liquid, such as hydrogen peroxide, results in the production of free gaseous oxygen. This working fluid may act directly on the blading of a turbine of the power plant or may be supplied to an auxiliary starting turbine or other motor. When hydrogen peroxide is used, phosphoric acid, sodium phosphate or 8-oxyquinaline is added as a stabilizer. It is forced by compressed air into a steam generator formed by a chamber containing accelerator salts, such as calcium permanganate and potassium oxalate, carried on porous blocks of stone or cement. In a jetpropulsion plant, the starting fluid is delivered to a chamber 26 and is directed on to the running blades 18 of the main turbine by a group of nozzles 27 which extends over one-ninth of the circumference of the stator structure. The nozzles are formed by grooves in the ring 25 which are closed by a conical surface on the part 29. Specifications 582,151 and 585,509 are referred to.

Patent GB-441617-A (GB)
Title: Improvements in or relating to circular looms
IPC: D03D37/00
Filed: 1934-07-23
Abstract: 441,617. Circular looms. BRITISH CELANESE, Ltd., 22, Hanover Square, London, and JABOULEY, J., c /o British Celanese, Ltd., Spondon, near Derby. July 23, 1934, No. 21458. [Classes 142 (i) and 142 (ii)] The ring 10, which surrounds the non- rotating warp threads, and carries the vane wheels for engaging the shuttles as described in Specification 413,376 is rotated so as to rotate the shuttles around the loom axis by a shaft 12 driven from an electric motor 21, stop mechanism operated upon warp failure &c. causing substantially instantaneous operation of declutchingmechanism so as to reduce the resistance to stopping of the parts brought to rest by the stop mechanism. The declutching means may comprise a differential gear the housing of which is integral with a pulley driven by a belt from the electric motor 21 and carries two sets of gears arranged in intermeshing pairs. One set engages a gear keyed to the shaft 12, whilst the other set engages a gear on a loose sleeve fixed to a brake drum 30. A brake band 31 for this is operated by a lever 36 controlled by an electromagnet 38 in a circuit comprising also-an electromagnet 43, switches of the type described in Specification 424,789 and a source of current. The circuit is normally closed, the brake 41 is applied and the shaft 12 is rotated by the differential gearing. When warp failure &c. occurs, the circuit is broken, both electromagnets are de-energized, the brake band 41 being removed from the drum 30, which then takes the drive from the motor so that the shaft 12 is no longer driven, whilst the de-energized electromagnet 43 allows a spring to rock a lever 49 and free a spring-controlled lever 47. This applies a brake band 45 to the ring 10. The shuttles and the vane-wheel driving-mechanism may be light. The shedding wheels 4 may be driven by the ring. The lever 36 may be used to start the loom gradually. A switch may be actuated by one of the levers 36, 43, 47 to switch off the motor. A differential gear of the bevel wheel type may be used. Specification 420,090 also is referred to. The Provisional Specification refers also to Specifications 285,435, [Class 142 (ii)], and 396,758, and states that the differential gear housing may be furnished with a gear or chain sprocket.

[Classes 83 (ii) and 83 (iv)] [Also in Group XXXVI] Uniting by fusion.-Connecting wires are attached to the base-plate of a blocking layer rectifier, by spot-welding with an impulse of current. A condenser 8 of large capacity, e.g. 1000 microfarads charged to 400 volts is connected to a supply reel of connecting wire 7 and via tongs 5 to the base-plate 1. When contact is made between the base-plate held in the tongs 5 and the end of the reel of connecting wire 6 the discharge current of the condenser welds the wire 6 to the point of contact. The wire is then cut to the required length and the operation may be repeated. The condenser is re-charged by a suitable device 9. When using a stranded wire a fused ball is first formed at the extremity thereof by placing the ends of two wires against each other and passing a condenser discharge therethrough. The plate 1 may be of aluminium and the wire of copper.

In the apparatus shown, the web is fed from a stock-roll 186, Fig. 3, the separating-liner passing over a roller 209 to a take-up roll 210, and the rubber over rollers 196, 213 to a roller 215, which is arranged under a series of cutting-discs 221. The cutters are mounted between a pair of pivoted arms 223, which are spring-pressed towards the roller 215 but can be raised and held clear of the latter by the engagement of a notched link 229 with the shaft 218. The severed strips 183 are separated by rollers 237 on an arm 236 and are guided by adjustable plates 153 into alignment with the beads 74 which, in operation, are supported on driving- rollers 72. Rollers 165, mounted on pivoted arms 163 arranged between the plates 153 cooperate with a roller 167 having an enlarged portion engaging the roller 112. Mounted under the latter are bead-supporting rollers 83 on pivoted arms 79 which are pressed upwardly by springs 80. The stretcher-rolls 76, 77 for operating on the flat sides of the beads are carried bv arms 75 bolted to a fixed bracket 71. The oblique stitcher-rolls 108, positioned between the rollers 76, 77 are mounted on arms 106 fixed to a cross-piece 101, which is carried by a two-armed pivoted lever 97 fitted with a counterweight 98. The other end of the arm 101 carries the roller 112, which is fitted with an adjustable brake. When a sufficient covering of rubber has been applied, the strips are severed by a cutter 142 carried by a manually-operated slide 141, which is moved up to the roller 112 against a counterweight. This movement of the slide controls a clutch to stop the feed from the stock-roll, the bead-driving rollers continuing to rotate in order to roll down the severed ends of the strips. Treadles 36, 136 are provided for actuating a bead-lifter 130 and the main-shaft clutch respectively.

Title: Improvements in or relating to a method of and apparatus for charging a stream of liquid with powdered material for fire extinguishing purposes
IPC: A62C5/00
Filed: 1929-07-12
Abstract: 315,426. Pyrene Co., Ltd., (Assignees of Timpson, L. G. M.). July 14, 1928, [Convention date]. Mixing solids with fluids in flow.-In charging a flowing stream with powdered material for fireextinguishing purposes, for example for producing foam, by passing the stream to the surface of the material in a container, the level at which the stream is introduced is progressively lowered as the material is exhausted. This lowering may be effected by manual manipulation, or automatically. As shown, a container 5 for the powder is provided with four spray heads 6 - - 9 supplied with water by a main pipe 29 under control of valves 12 - - 15. Foam escapes by a pipe 10. The valves 12 - - 15 are controlled by cams 16 - - 19 in a tank 25. The pipe 29 supplies water to the tank 25 under control of a normally open valve 31 and a normally closed valve 30. When the valve 30 is opened, the rise of the float 26 first opens the valve 12 supplying the spray head 6. As it rises higher it gradually closes the valve 12 and opens the valve 13, and so on for the valves 14 and 15, as the supply of powder becomes exhausted. By the time the powder is entirely used, a, float 40 has been lifted by the water in the tank, so as to close the valve 31. The valve 30 may be opened automatically, to start the apparatus, by a weight 36 normally supported by a fusible bail 38. The latter is fused by an electric circuit 39 operated by hand or automatically. The valve 30 is a three-way valve, and when it is in its normal closed position it serves to drain the tank 25.
