Title: Improvements in or relating to coffee makers
IPC: A47J31/043
Filed: 1962-04-30
Abstract: 980,710. Coffee makers. SUNBEAM CORPORATION. April 30, 1962 [June 14, 1961], No. 16474/62. Heading A4D. [Also in Divisions H2 and H5] An electric coffee maker, of the vacuum type described in Specification 625,797, comprises an upper infusing vessel 22, Figs. 1 and 4, having a depending outlet stem 22a, which fits easily into the flanged mouth 26 of a lower, beverage-holding vessel 21 and is connected to a tube 23 extending downwardly into the latter, an elastic sealing ring 35 accommodated in grooves 27 and 34 respectively in the mouth 26 and the stem 22a, and a rigid ring 37, to which the bifurcated inner ends of two diametrically opposed heat-insulating handles 38 are pivoted, by pins 38a engaging upwardly projecting ears 37b on the ring 37. These ears are received in gaps 39 between the bifurcations of the handles. When the handles are depressed, cam surfaces on their bifurcated ends engage the under surface of the vessel 22 and the ring 37 and cause the latter to move downwards on the stem 22a, so that a depending flange 37a, on the ring 37, presses the sealing ring 35 into the grooves and locks or couples the vessels tightly together. Preferably, both vessels are made of metal and the base portion 30 of the vessel 21 is made of copper, but the upper vessel may be made of glass or plastic material. Calibrations may be stamped into the wall of the lower vessel 21 to indicate beverage levels corresponding to cups of coffee. The mouth 26 of the lower vessel may be provided with an extension (not shown) defining a pouring spout. The thermostatically controlled electric heating apparatus is contained in a dished chamber 60 made of insulating material and provided, in a recess 63 around its lip, with a sealing gasket 64. The chamber 60 is tightly clamped and sealed to the base of the lower vessel 21 by a threaded stud 32 and a nut 61 provided with a spring washer 67 and a sealing gasket 68. The main heating element 52 is energized to heat the base 30 of the lower vessel 21 until substantially all the water placed therein is at brewing or infusion temperature, e.g. exceeding 200F., and is then forced, through the tube 23, into the upper vessel. The current heating the element 52 is then automatically switched off by a bi-metallic strip 99, which opens a snapacting switch 103, Fig. 5, (see Division H2). The brewed coffee beverage then passes from the upper vessel 22, through a filter 42 and the tube 23, into the lower vessel 21, in which it may be maintained at serving temperature, e.g. 160 to 180F., by an auxiliarly electric heater 82, to which current is supplied through contact pins 73, 74, which also supply current to the element 52. The position of the whole switch assembly 103 relative to the strip 99 may be adjusted, manually, by a screw 126, 128. When desired, the switch 103 may be closed, to energize the element 52, by the manual turning of a knob 124 (see Division H2). An indicating lamp 130, Fig. 4, preferably a neon bulb may be connected across the element 52 to give a light signal, e.g., through a lens 141.

Title: Improvements in or relating to ultra-high-frequency impedance transformers
IPC: H01P5/04
Filed: 1945-06-28
Abstract: 599,021. Matching impedances. TURNER, L. B., and BUCKINGHAM, J. June 28, 1945, No. 16551. [Class 40 (iii)] A resonant cavity 1 for matching impedances contains one or more adjustable shaped coupling members such as the hard brass cranks 9, 10, ,and a tuning-plunger 4, the coupling being tight when the cranks are near the wall. The device shown is suitable, in a system employing the E10 mode at 3,000 Mc/s., for joining two coaxial transmission lines which are coupled to it through sockets 2, 3, and cranks 9, 10. The latter are connected to the inner conductors of the coaxial lines through conical bearings 9a, 10a, and at their other ends 9b, 10b to the wall 1b of the cavity, handles 7, 8 being provided so that the cranks can be turned to positions indicated by pointers 5a, 6a, and scales, and can be clamped by means of grub screws, Fig. 4 (not shown). Detuning of the cavity due to alteration of the coupling reactances when the cranks 9, 10 are adjusted is counteracted by means of the tuning plunger 4, which may be screw-threaded and provided with a pointer and scale and a clamping- screw, Fig. 4 (not shown). An error in the length of the crank can be compensated by attaching to the end 9a or 10a a semicircular wire 11, Fig. 3, which adjusts the susceptance to have equal positive and negative ranges but is free from coupling with the resonator. Provision may be made for four or more external circuits, Fig. 4 (not shown), and the positions of the ends such as 9a, 9b may be reversed in some of them.

Title: Means for transmitting electric charged carriers through space
IPC: H01T14/00
Filed: 1942-11-23
Abstract: 601,207. Radio systems. FORMAN, J. Nov. 23, 1942, No. 16592. [Class 40 (v)] [Also in Group XL (a)] Means for transmitting electric charged carriers, e.g. ions, through space comprises means for transmitting an asymmetric carrier wave of electromagnetic radiation in the direction of propagation which acts on a cloud of electric charged carriers to impart to them intermittent but successive accelerations in the direction of propagation of the wave. As shown in Fig. 2, electrodes 3 are coupled to the oscillatory circuit of a magnetron oscillator 1 to produce an " electron-ion flame " F in the manner described in Specification 601,206. As the flame F exists only for the negative halfcycles of the oscillator 1, only the negative half-cycles are radiated. This wave is stated to have an electric component in the direction of propagation and acts on the sheath of positive ions surrounding the flame causing them to be accelerated toward a collector electrode C to give a direct current through a micro-ammeter M. The action is facilitated by giving the ions a high positive potential from a source 5. In the arrangement shown in Fig. 3, the radiation is beamed in a dielectric guide 6 at high potential, and the collector C has a reflector 7 and circuit 8 tuned to the carrier frequency. Alternatively, the radiation may be beamed by means of magnetic lenses (Fig. 6, not shown). In Fig. 4, the flame F is enclosed by a screen 10 made of " Cellophane (Registered Trade Mark), so that only the carrier wave is transmitted and this acts on a cloud of ions 9 local to the collector C. In'a further modification (Fig. 7, not shown), the flame is subjected to a pulsating D.C. so that the signal may be detected at the collector by means of a transformer.

Abstract: 914,633. Compressors. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. May 22, 1959 [May, 23, 1958], No. 16686/58. Class 8(1). Prevention of condensation of water within the working parts of a multistage air compressor during the starting-up period is effected by heating the air to above the dew point immediately prior to its entry into any one or more stages of the system. As shown air from a first stage 1, Fig. 1, having traversed an intercooler 8 and a water collecting pump 9 is fed through a duct 4 and a heating coil 10 within an electrically heated chamber 12 before entering a record stage compressor 2. A similar heating coil 11 is located between the intercooler 8, the sump 9 and a third -stage 3, which delivers to an aftercooler through a duct 7. The plant is suitable for replacing leakage air to the compressed air system of circuit breakers involving only a few minutes running at several hours intervals. An electric heater 13 is supplied with current through a switch 14, Fig. 2, which closes when pressure in the system falls below a predetermined value and through a normally closed switch 16. The so-heated element 13 then closes a thermostat switch 17 to energise a relay coil 15 which in turn closes a normally open switch 18 in the compressor motor circuit and simultaneously opens switch 16 and so cuts off the heater and closes a switch 20 to maintain current through the relay 15.

Title: An improved multiple-pole automatic electric switch
IPC: H01H71/58
Filed: 1942-11-26
Abstract: 563,528. Automatic circuit-breakers. LANDIS & GYR SOC. ANON. Nov. 26, 1942, No. 16778. Convention date, Dec. 2, 1941. [Class 38 (v)] Each pole of a multi-pole circuit-breaker is adapted to be separately released and, in releasing, trip the other pole or poles, and the handle is associated with the toggles of the poles through a single common locking or detent device. The movable contacts 14 are mounted on a transverse bar 4 by means of toggles 8, 9 which are normally held overset and acted upon by throw-off springs (not shown), the toggles being adapted to be independently broken by a trip force in the direction of arrows 37 so that pins 18 strike one arm 17 of a release member 12 freely pivoted on bar 4, the arm 16 of the other pole thus breaking the other toggle. When push button 1 is depressed, bar 4 is driven downwards by spring 5 and slot 3, and latched by a recess 21 in a spring pawl 19 pivoted at 20. At the same time, the spring-controlled abutment 33 on button 1 depresses a detent 27 until arrested by the upper slot end 28 engaging fixed pin 29, so arresting downward movement of 4. When released button 1. is raised by spring 5 and a spring 32 moves detent 27 clear, its pin 30 riding up the left side of fixed cam slot 31. To switch off, button 1 is again depressed, but abutment 33 clears the detent 27 and an abutment 6 on the button-stem 2 engages part 13 of the lever 12 and trips both poles ; bar 4 is released by abutment 7 engaging pawl 19 which, through a pin 26, pushes detent 27 back to the Fig. 2 position.

Abstract: 256,026. Marks, E. C. R., (Titan-Patente Akt.-Ges.). June 30, 1925. Furnace fireplaces; grates; air, supplying; steam, supplying.-A method of stoking furnaces consists in providing above the grate and within the firebox a low longitudial partition wall forming two longitudinal spaces which are fired alternately, one being liberally filled with fuel to the extent of several times the quantity usually thrown on so as to form a distillation space whilst the other contains a smaller quantity of coked fuel in a glowing state forming a heat storage, the combustion being completed in the firebox. A number of walls may be used, extending from the fire door well along the whole or only a part of the length of the furnace, and they are arranged to extend just above the top of the thickest layer of fuel used in stoking. The walls may be made solid or hollow and may have apertures along their upper edges or sides, they may be made in removable sections, and they may consist of, or only be covered with, refractory material. The walls may comprise firebrick-spaced upwardly-projecting, tubes 3, Fig. 1, or longitudinal chambers 8, Fig. 3, which are cooled by and are used for supplying above the grate secondary air, live or exhaust steam, a mixture of air and steam, or alternately exhaust and fresh steam. The walls may also comprise tubes b, Fig. 5, or chambers c reinforced by longitudinal stay bolts e and transverse stay bolts or screw bolts d as shown in Fig. 6, for circulating boiler or other water. The tubes b and chambers c may be longitudinally bent for the purpose of equalizing expansion and they may be welded on to the walls of the firebox. Specification 13661/05 is referred to.

Title: Improvements relating to Impact Wrenches
Inventor: BARBER ANTONY DOBSON
IPC: B25B21/02
Filed: 1966-04-18
Abstract: 1,184,892. Impact wrenches. HOLMAN BROS. Ltd. 13 April, 1967 [18 April, 1966], No. 16867/66. Heading B3N. A compressed-air-driven impact wrench comprises a rotary hammer 30 Fig. 1, axially movable so as to engage an anvil 16 by pneumatic pressure, and a centrifugal shuttle valve 52, rotatable with the hammer, which is biassed towards an operative position, in which the pressure acting on the hammer is relieved, to allow it to be retracted, but which is held in the inoperative position by centrifugal force so long as the hammer rotates above a certain speed. Valve 52 has a shuttle with two pistons of different areas. A sleeve 28 is splined to the shaft 21 of a sliding vane rotor 20, and hammer 30 is rotatable with, and axially slidable in sleeve 28. The inner end of hammer 30 is formed as a piston 44, and air is supplied to move the piston against a spring 46, through a passage 22, and a port 50 in anvil shaft 12, and thence along a groove 51 formed in the bore of piston 44, air from the piston also passing to the two pistons of valve 52, when this groove is aligned with the port. The cylinder 45 of piston 44 can be vented at the required time through valve 52, so as to allow spring 46 to retract the hammer from the anvil. In operation, hammer 30 is retracted, and air motor shaft 21 is rotated, thus rotating sleeve 28 and hammer 30. Air is also supplied along bore 22 into shaft end 26. Hammer 30 and sleeve 28 accelerate, and the shuttle of valve 52 moves radially outwardly to close the valve, due to centrifugal force. Hammer 30 turns relative to shaft end 26 until slot 51 and port 50 are aligned, thus admitting air into cylinder 45. Hammer 30 is moved axially against spring 46 until the dogs 38 and 17 on the hammer and anvil engage. The fastener is tightened, and due to the slowing down of the parts of the wrench, the air that passes to the differential pistons of valve 52, overcomes the centrifugal force, the shuttle moves radially inwardly so as to vent the cylinder 45, and spring 46 retracts hammer 30. A further cycle commences, and impacts are thus produced until the motor stalls when the fastener is fully tightened. For loosening a fastener the motor is rotated in the opposite direction.
