Title: Improvements in or relating to apparatus for separating dust from gases
IPC: B04C1/00
Filed: 1935-05-30
Abstract: 439,618. Centrifugal dust-separators. SULZER FRERES SOC. ANON., Winterthur, Switzerland. May 30, 1935, No. 15747. Convention date, June 2, 1934. [Class 23] Where dust separation is effected through apertures in a spiral casing round a centrifugal fan, a suction effect is applied to the apertures to distribute the separating action uniformly amongst them. The main stream of dust-laden air enters the main centrifugal fan b by the pipe a, and it passes to the main delivery pipe i through the spiral conduits c, d. These conduits c, d have dust apertures e, f and g, h respectively which are connected by conduits k, l to a container m from which air is drawn through a pipe n by the auxiliary fan o. This discharges through spiral passages having dust outlets leading to the chamber t while the cleansed stream passes through the ducts s, n<1> to the main supply pipe a. The dust separated in the conduits c, d is drawn through the openings e, f, g, h and passes to the container m where a large part of it settles gravitationally. Some dust-laden air passes from the container m through the pipe n and fan o where more dust is separated and passes to the chamber t. Air returns from the chamber t to the fan o through the pipe u.

Title: Improvements in or relating to gas-pressure brakes
IPC: B66B5/18
Filed: 1937-06-08
Abstract: 498,513. Safety suspending-apparatus for lifts. KOCHMANN, W. June 8, 1937, No. 15797. [Class 78 (iii)] [Also in Group XXXIV] In a device for operating a brake particularly in emergency, wherein a difference in gas pressure is produced at the time of requirement by a chemical or physical reaction or conversion, successive stages of the braking operation are automatically controlled either by constructional means or by the form of the pressure-producing substance. In Fig. 1, ammonia or sulphur dioxide on the right of the piston 2 is absorbed by water or caustic soda solution injected at 6, atmospheric pressure at 1a applying the brake 4a. The liquid is maintained at constant pressure by the spring-pressed piston 9 in the reservoir 8, and its delivery valve 11 is controlled in accordance with the requirements of the brake by a cam 15 preferably such that the valve is in turn opened wide, partially closed, and opened wide. In the case of the breaking of a lift rope, a contact may be made by a spring, Fig. 5 (not shown), or by an inertia device, Fig. 6 (not shown), or by a centrifugal governor, to energize a magnet 20 releasing a trip 17 to apply the brake. The air inlet 1a may be controlled instead of the valve 11. The reaction may be arranged to take place in a container separate from the cylinder 1, permitting readier dissipation of heat and the interposition of a filter. In Fig. 2, four chambers 21 formed on the brake cylinder 1 and containing combustible material sealed at 22 till ignited electrically at 20, may be used successively. The material consists of separate compressed portions burning at different rates. The control may also be exercised in a pipe conducting the pressure gas to the brake piston 2, for instance by a throttling-cock 29, Fig. 4, having a spring- controlled arm 30 carrying an inertia weight 31, or by an inertia throttling-member 31<1>, Fig. 7. Or relief valves in both the vacuum and pressure brakes may be similarly controlled. A breaking rope may also ignite a percussion cap of the combustible substance, or break vessels bringing acid and carbonate into contact. A hand initiating-switch or cable may be provided, and thermal or photoelectric switches may cause actuation in case of fire. The emergency devices may act on the ordinary braking-elements through oneway connections.

Abstract: 1530702 AFC systems; radio navigation systems TRACOR Inc 20 April 1976 [28 April 1975] 15910/76 Headings H3A and H4D An AFC system suitable for use in an Omega radio navigation system which compares the phases of signals received from a plurality of stations comprises a plurality of phase locked loops for receiving a plurality of discrete frequency signals and employs cross-coupling between the outputs of the loop phase detectors 42, 42a for modifying the output of each phase detector for providing effective loop control in the event of a temporary loss of one or more signals and for improved periodic updating of the phase error signal within a period or in the following period. The phase detector outputs may also be modified by signals related to the true air speed, magnetic heading of the receiver aircraft. Each phase detector receives the input signal and a reference signal at the same frequency from a loop controlled oscillator or a computer processor (Fig. 3, not shown). The amount of cross-coupling between loops may be varied. The basic omega navigational system employs a plurality of stations each broadcasting at a unique combination of time durations on three discrete frequencies. A hyperbolic Omega receiver measures the phase of two or more station signals against a reference oscillation generated internally to provide positional information.

Title: Improvements in or relating to machines for stacking metal plates and insulating plates for capacitors
IPC: H01G13/00
Filed: 1945-06-22
Abstract: 593,212. Feeding sheets.. SPORING, P. A., JOHNSON, C. P., and TELEGRAPH CONDENSER CO., Ltd. June 22, 1945, No.15961. [Class 100 (i)] [Also in Group XXXVI] A machine for stacking sheets, e.g. metal and mica plates in alternate sequence for capacitors, comprises magazines 6 and 5 containing respectively metal and mica plates, and one or more suction pickers 17 operated to transfer the plates alternately to a stacking jig, as at 14, where they are assembled in alternate relationship. The magazines are mounted in sets on spaced parallel bars 2, each set comprising a metal magazine on either side of a mica magazine and having its corresponding stacking jig. The machine operates in the following manner. The plates are held in a clip in each magazine, and the suction pickers are oscillated vertically and horizontally to take up plates from the magazine and deposit them on the corresponding jig, the suction being cut off and applied at the correct time by an automatic valve 54 on a supply tube 52 to the pickers 17, the valve being actuated by cams and arms from a rotatable spindle 32. The bars 2 are reciprocated longitudinally by means of a cam 41 on a spindle 42 driven by a gear and. sprocket from the spindle 32. The cam 41 has a groove 45 in which is a .cam roller connected by an arm 50 to the bars, the shape of the groove being such as.to halt the appropriate magazine under the picker. In this way the pickers take mica and metal plates alternately, and the metal plates are taken from alternate magazines to provide for the staggering of alternate metal plates in the jig, the metal magazines being set in a predetermined position on the bars 2 to achieve this. The pickers 17 are oscillated vertically and horizontally by cams 34 and 31 respectively, carried on the spindle 32, the cams serving by cam rollers and cranks to rock the corresponding spindle 37 on 28. The movement of the spindle 37 is communicated to an arm capable of vertical motion carrying the picker, and the spindle 28 is attached to bars 22 free to move horizontally and likewise secured to the picker. The plates are maintained flush with the top of the magazine by a piston open at its opposite end to pressure supply. On completing the stack in the jig, a spindle 86 is rotated to enable fingers 91 to hold each stack of plates firmly in the jig whilst from beneath a rod carrying two pairs of pins is forced up to bend the ends of the metal plates over the mica plates. In the Provisional Specification is described a - modification in which a series of magazines, alternate magazines being filled with metal and mica plates respectively, are disposed round part of a circle, each magazine having its corresponding picker, whilst stacking jigs are carried by a member adapted to be rotated relative to the magazines and pickers.

Filed: 1939-06-01
Abstract: 529,599. Thermionic valves. JOBST, G. June 1, 1939, No. 16131. Convention date, June 2, 1938. Addition to 518,665. [Class 39 (i)] If in apparatus for causing electrons to arrive in groups at a delivery anode as described in the parent Specification the length of the anode is large compared with the wavelength of the oscillations produced the electrons travelling along the anode will reach the antenna at different times and the group will be dispersed. To avoid this the apparatus is so arranged that the electrons striking the anode at the end near the antenna reach it later than those striking at the other end. This is effected (a) by inclining the anode to the path of the electrons (b) by causing the oscillating voltages applied to the accelerating electrodes to travel along them at a rate comparable to that at which the electrons travel along the anode or (c) causing the direct current components of the accelerating fields to be stronger at the end remote from the antenna than at the other. The anode may consist of a number of successive inclined surfaces 54 as shown in Fig. 3, so arranged that the electrons striking each surface arrive at the end of that surface together and each surface delivers a separate impulse to the antenna, thus producing frequency multiplication.

Abstract: 551,039. Sliding - clasp fasteners. CARR FASTENER CO., Ltd., and PARKIN, L. Dec. 15. 1941, No. 16149. [Class 44] In a sliding - clasp fastener having the stringer ends secured by plates pivoted together so that one of the plates may swing laterally into and out of the slot in the slider as in Specification 527,825, said plate has means for guiding the slider into correct engagement with the fastener elements. The invention is particularly applicable to a fastening in which the stringers may be separated, when required, by lateral pull, as, for example in Specification 542,953 wherein the slider can be moved beyond a resilient top stop into a position beyond fastener elements on one of the stringers which can then be pulled laterally out of the slider.. As shown a pair of plates 8, bent to provide channel portions 7 and cut away ut the upper edges as shown to accommodate the wedge 15 of slider 4, are secured on opposite faces of stringer 2 by rivets 9. A plate 5 bent to embrace the edge of stringer 1 is secured by rivets 6 and is pivoted between plates 8 by a pin 11 the head of which, or a separate stop, arrests opening movement of the slider. Plate 5 has a projection which may be of wedge or other form but'is shown as an embossed dome 12. The projection is disposed so that when the pivoted plates are closed together it passes over the upper end of the side wall 14 of the slider and makes sliding contact with the inner face of said wall as the slider is moved to close the fastener, thus guiding the slider into correct engagement.

In a process for the programme control of a machine, whereby one or more operations are performed during a predetermined portion or predetermined portions of a programme cycle, and wherein the duration of the or each operation is controlled by the state of two sensitive elements, each of which may assume a sensitized or a non sensitized state, the state of each of the sensitive elements is maintained unchanged during half of the programme cycle. Photo-sensitive resistors are disposed at selected positions such as N and Q adjacent apertures in a cylindrical member 1 containing an axially disposed lamp 3, and a screen 2 covering half the inner periphery of the cylinder 1 is rotatable to screen each photo-sensitive element from light from the lamp 3 for half of each programme cycle. Each photo-sensitive resistor 5 is connected in a circuit comprising transistors TR1, TR2, as illustrated in Fig.3. When a resistor 5 is activated by light from the lamp 3 an output signal appears at A and not at B, and when the resistor 5 is screened an output appears at B and not at A. Thus if it is desired to obtain a programme control signal for the duration of the movement of the rear edge 2<SP>1</SP> of the screen 2 between two photo-sensitive resistors at P and Q, signals are taken at the terminals B and A, respectively, of the two photo-sensitive resistor circuits at the points P and Q. These two signals are both zero during movement of the edge 2<SP>1</SP> between the points P and Q, and a NOR logic circuit connected to said terminals B and A will then provide the required output control signal.
