Abstract: 779,904. Silencers for gaseous currents. VOKES, Ltd. Aug. 19, 1955 [Sept. 9, 1954], No. 26184/54. Class 7 (2). A tube leading into a low pressure chamber A is formed as a venturi whereby the velocity of the gases is increased within the tube, and is provided with one or more slots 13 in the wall thereof giving access to at least one chamber B of dimensions smaller than those of the chamber A. The air-intake silencer shown in Fig. 1, comprises a cylindrical casing 1 provided at one end with a curvilinear inlet passage 3 concentric with the inlet tube having a parallel-sided section 4 and terminating in a flared outlet section 5; a bridge-piece 6 spans the mouth of the tube and carries an end cap 9 which locates a crimped, cylindrical air filter 10. The diameter of the section 4 of the inlet tube is about one quarter of that of the casing 1. Chambers B, C formed by annular baffles 15, 16 communicate with the inlet tube by way of slots 13, 14. In a modification, an exhaust silencer comprises a cylindrical casing 21, Fig. 2, and an internal foraminous tube 26 between the inlet 22 and the outlet 24 of the casing, the inlet being formed with a convergent section from the outlet end of which the tube 26 is of substantially constant cross-section and equal to that of a tail pipe 27. The latter terminates in a narrowangle diffuser 32 surrounded by a chamber M, or chambers, to tune out the fundamental or selected harmonics of the resonant frequency of the tail pipe 27. Within the annular space between the casing 21 and the tube 26 is a divergent/convergent conical baffle 28 the interior of which is divided by annular baffles 29, 30, and 31 into two pairs of chambers E, K and F, L of different acoustic capacities; two further chambers G, H are provided between the baffle 28 and the casing 21.

Abstract: 1,089,749. Gas scrubbers. H. IDEMITSU and M. IWANGA. June 22, 1965 [June 27, 1964; March 3, 1965], No. 26264/65. Heading B1R. A gas to be scrubbed is passed from an inlet pipe 8 and a fish-tail nozzle 9 to gas ducts 12 and 13 and discharged therefrom below perforated plates 19 and 20 immersed in liquid, an imperforate plate 21 being arranged above plate 19 to extend the path traversed by the bubbles of gas rising through the perforations in plates 19 and 20. The ducts 12 and 13 are open at their inlet ends and a flow of liquid therethrough is induced by the gas discharged from the nozzle 9. The scrubbed gas leaves through an outlet 24 and is driven by a blower 25 to bubble through a second body of liquid containing perforated plates 31 and 32 and an imperforate plate 33. Scrubbing liquid introduced at 4 into the upper section of the scrubber passes to the lower section through a pipe 3. In a modification (Fig. 3, not shown) the gas from the nozzle 9 enters a box-like structure immersed in liquid and having a perforated top face above which an imperforate baffle is arranged.

Title: Electrical temperature control apparatus
IPC: B29D30/06
Filed: 1958-08-18
Abstract: 852,880. Automatic temperature and current control systems. GOODYEAR TIRE & RUBBER CO. Aug. 18, 1958 [March 31, 1958], No. 26444/58. Class 38 (4). In a tyre vulcanization and retreading machine, the temperature of an electrical heating element is maintained at a pre-determined value by switching off the current, when the resistance of the element reaches a predetermined value, by means responsive to the voltage and current of the element. A power supply is connected through a switch 16 to energize a timer 23 set to a desired vulcanizing time, a cycling timer 27 and a power-on indicator light 25. After 30 seconds a mercury switch 30 is closed by the cycling timer to energize a relay 28 which closes a contact 31 locking-in the relay, and contacts 47, 48 connecting the heating element 51 to the supply, a contact 26 being opened to de-energize the timer 27 and the power-on light 25. A current relay 35 closes a contact 34 to light a heat-up indicator lamp 32 and energize a transformer 33 applying through a rectifier 36 a direct voltage, proportional to the supply voltage, to a resistor 42. Through a current transformer 46 and a rectifier 45 a direct voltage, proportional to the current through the heating element, is applied to a resistor 43. The potential difference between resistors 42, 43 causes a current to flow in a coil 40 of a meter relay 39 and deflect a pointer 38. At a pre-set deflection, a circuit is made through a relay 37 and maintained by a current flowing through a hold-on coil 41. A contact 29 of relay 37 opens to de-energize the relay 28 and reset the temperature control system, the cycle being repeated after 30 seconds by the timer 23. In a modification, Fig. 3 (not shown), an auxiliary circuit controlling a plurality of heating elements is connected to points 52a-55a and 14, 15. The auxiliary circuit comprises a sequence switching arrangement whereby the heating elements are separately temperature controlled, a relay steps the sequence switch past a disconnected heating element.

Title: A process for regenerating bauxite
IPC: B01J20/08
Filed: 1946-09-03
Abstract: Bauxite, used in the purification of high-boiling hydrocarbons such as lubricating oils in liquid phase is regenerated by oxygen containing flue gases, the water content of the flue gases before use being reduced to 4 per cent by volume or less.  The flue gas may be obtained by burning off the deposits on the bauxite, the gas so obtained being then cooled to separate water, mixed with air and returned to the bauxite.  The process may be effected under pressure.

Title: Improvements in or relating to electrical thermally responsive relays
IPC: H01H43/30
Filed: 1957-08-22
Abstract: 817,122. Temperature-responsive actuating-elements. BRYANT ELECTRIC CO. Aug. 22, 1957 [Aug. 29, 1956], No. 26521/57. Class 64(2) [Also in Group XXXVII] A thermal relay has a U-shaped framework of insulating material comprising two side legs 2 and 4 and a base portion 6 carrying four plug pins 50. Resistance wire 116 is wound around the base portion and an insulating member 92 pivoted at 98 in recesses in a metallic contact actuator 82, itself pivoted at one end in the top of leg 2 and guided by a slot in the top of leg 4. The wire 116 may be secured in place by being partially embedded in an asbestos member 118 or by coating members 92 and 118 with varnish or adhesive. The wire 116 is tensioned by a spring blade 100 bowed between the actuator 82 and the free end of a metal plate 64 connected to one plug pin 50. The blade 100 carries a contact 102 co-operating with a fixed contact 78 mounted on an extension from a plug pin 50. The other two plug pins 50 act as terminals for the wire 116. Adjustment of the moving contact 102 is provided by a screw (Fig. 2, not shown) engaging an indentation 68 in the free end of the plate 64, to lift or lower the latter and thereby vary the initial amount of bow in the blade 100. Side cover plates 126 fit in grooves in the legs 2 and 4 and are retained by tabs 128 on a top cover 120. The side covers 126 may have perforations 130 or may be omitted so that the relay may respond to rate of flow or change in temperature of a stream of fluid. In a modification (Fig. 8, not shown) the spring blade 100 is mounted centrally on the plate 64 and the actuator 82, the latter being loosely guided at each end, and the contacts are arranged to break instead of make as the wire 116 expands. The casing may be sealed and evacuated.

Depression of a key, say 12G, initially moves the lever 16G, against its spring 28 about pivot 26 to bring actuator 18G into engagement with cam 20G and thereby rotate the shaft 14 until the actuator seats in notch 22. In order to allow the latch plate 24 to engage, key 12G must then be depressed further, to move pivot 26 against the action of spring 34, thereby ensuring that the shaft 14 is held in position without backlash. The latch plate 24 is released in known manner (not described) by depression of a further key 12A . . . 12G. To avoid backlash the rod 26 seats in notches in the arms 32 and engages inclined surfaces in the opening of each lever 16. Moreover, an inclined leaf spring 36 engages the end of shaft 14 to prevent backlash in its bearings.
