Title: Improvements in and relating to methods of making glass enclosures
IPC: H01J5/24
Filed: 1940-01-10
Abstract: 534,178. Making electric incandescent lamps. BRITISH THOMSON-HOUSTON CO., Ltd. Jan. 10, 1940, No. 523. Convention date, Jan. 12, 1939. [Class 39 (ii)] [Also in Group XXIII] In order to facilitate the sealing together of glass sections in definite relation with respect to one another to form an enclosure, particularly an electric lamp of the kind described in Specifications 515,091 and 526,924, the sections are formed with sealing-surfaces at the outer edges of their rims, and with co-operating surfaces which keep the parts in registry during the sealing-operation, the co-operating surfaces being separated after sealing to prevent the formation of strains in the seal. The two sections, 11, 12, Fig. 2, are provided with sealing surfaces 24, 25 respectively, and the section 12 is provided with an annular flange 30 which cooperates with a flat surface 29 on the section 11. The parts 29, 30 are spaced from the surfaces 24, 25 a sufficient distance to be unaffected by the heat of the sealing burners. When the sections are assembled, the rims are heated by pointed flames from a number of burners 34, the sections being rotated while being heated. As the glass softens, the section 12 descends by gravity until the flange 30 rests on the surface 29. When the seal is completed, and while the glass is still plastic, the sections are separated slightly, as shown in Fig. 3, to prevent strains from being set up in the seal. The separation may be effected by blowing a gas, preferably nitrogen. into the enclosure to lift the section 12 until it is arrested by a stop. The separation can be effected, also, by mechanical means such as by a suction cup gripping the outer surface of the section 12.

Title: Differential amplifier
IPC: H03K17/041
Filed: 1970-01-06
Abstract: 1287081 Transistor gating circuits RCA CORPORATION 6 Jan 1970 [7 Jan 1969] 584/70 Heading H3T A gated differential amplifier circuit comprises two amplifying devices (transistors Q1, Q2) shunted by respective unidirectional conduction devices (diodes 33, 34) via gating means (differential transistor switch Q3, Q4) whereby one path or the other is connected to a first constant current source (between terminals 20, 25) via output impedances 14, 16, while a second constant current source passes a smaller current continuously through the amplifying devices and output impedances. The circuit is used for readout of a computer memory; during the " write " phase the circuit is in its standby state but is subjected to high levels of noise on its input terminals 12. In these circumstances, Q3 in the gating means is off and Q4 is conducting so that the first constant current passes through the diodes 33, 34. It is regulated by a transistor Q5. The amplifying transistors Q1, Q2 are " kept alive " by the second constant current source, regulated by a transistor Q7, so as to be more rapidly ready for use when Q3, Q4 are switched over (by a signal from point 44 in the emitter resistances of a transistor Q6 which is made conducting by a gating signal on terminal 38). Also, because Q1, Q2 are partly conducting, noise on terminals 12 will differentially alter the volt drop across output impedances 14, 16, and hence the conduction of the diodes 33, 34 in the opposite sense, thereby preventing the noise signal reaching the output terminals 31, 32. When the circuit is switched on by the gating signal the diodes are disconnected by Q4 and a biasing potential is applied from point 43 over a diode 45 to reduce the effect of their capacitance.

Abstract: 1,164,243. Liquid cargoes transferring; counterbalancing apparatus. FMC CORP. 4 Jan., 1968 [17 Jan., 1967], No. 619/68. Headings B8B and B8E. A marine loading arm comprises a riser assembly 12 mounted on the deck and inner and outer mutually pivoted pipe sections 30, 38 actuated by pairs of singleacting hydraulic cylinders 68, 60 respectively to position a manifold coupling assembly 40 correctly for it to be bolted to a ship's manifold. The pipe sections are counterbalanced by a weight 80 adjustable along a rigid beam 78 connected to the pipe section 30 by means of a pair of hydraulic cylinders 81. Since the counterbalancing movement required for any position of the pipe sections varies according to the amount of liquid in the pipes means are provided to automatically adjust the position of the weight 80 to effect approximate balance before movement of the sections occurs. A common hydraulic control circuit for the cylinders 68 and 81 is provided including resistance valves arranged to sense imbalance and to divert actuating pressure to operate a cylinder 81 to appropriately re-position the weight 80 until approximate balance occurs when the actuating pressure is all applied to the cylinders 68 to re-position the pipe sections.

Title: Sound-reproducing apparatus such as loud-speakers
IPC: H04R9/04
Filed: 1926-01-09
Abstract: 245,796. British Thomson-Houston Co., Ltd., (Assignees of Rice, C. W., and Kellogg, E. W.). Jan. 9, 1925, [Convention date]. Loud-speakers; magnetic instruments; diaphragms.-A sound-reproducing apparatus, more particularly a loud-speaker, is formed with a rigid conical diaphragm having its larger end surrounded by a rigid or non-resonant baffle. The actuating coil is preferably secured, to a reinforcing cylindrical sleeve, at the inner end of the diaphragm. The diaphragm is supported by flexible devices which have so low a restoring force that the natural periodicity of the diaphragm is low down in the range of audible frequencies. The frustum shaped diaphragm 1 is secured at its outer edge to a supporting ring 2 by a ring 3 of flexible material, such as silk, rubber or thin leather. The inner edge of the diaphragm is formed as a cylinder 4 reinforced by outer and inner rings 5, 6, an actuating coil 7 being secured around the inner ring 6 and being disposed in the annular air gap 8 between the concentric pole pieces 9, 10. In order to prevent any tendency for lateral movement of the coil 7 in the gap 8, the pole piece 9 is formed with a projection 10<a> to which is secured, by a screw 12, a spider 11<a> having resilient arms 13 connected by radially extending links 14 to the inner edge of the diaphragm. The links 14 may be in the form of a continuous length of cord or fine wire threaded through holes in the ends of the arms 13 and the inner edge of the diaphragm. The top of the diaphragm is preferably left open so as to eliminate any enclosed air space between tho diaphragm and pole pieces. The ring 2 is mounted on the pole piece 10 by brackets 15 and in order to prevent circulation of air between the front and back of the diaphragm around the ring 2, the path between the front and back of the diaphragm is lengthened to a distance of about a, quarter wave length or more by surrounding the ring 2 by a baffle 18 of fairly massive material. The baffle 18 may conveniently take the form of an enclosing cabinet for the diaphragm and its actuating mechanism, the ring 2 being fitted in an opening in the front of the cabinet, the back of which is preferably open to prevent any resonant effects due to confined air. The pole piece 9 is surrounded by a coil 11 which may either be supplied with a steady direct current or with rectified alternating current, in which case the end 19 is made to constitute a short circuited turn of low resistance by making it of copper. Specifications 231,420 and 231,421 are referred to.

Title: Improvements relating to hydraulic devices for airplane landing gear wheels
IPC: B64C25/50
Filed: 1944-01-18
Abstract: 574,212. Aircraft undercarriages. HOUDAILLE-HERSHEY CORPORATION. Jan. 18, 1944, No. 952. Convention date, July 2, 1942. [Class 4] Hydraulic mechanism for steering and damping shimmy oscillations of an aircraft landing wheel comprises a cylinder C housing a rotatable piston 23 coupled to the undercarriage leg 10 by means of a link 25. The cylinder is divided into four working chambers 38, 38<1>, 39, 39<1>, by means of pairs of vanes 34, 34<1> and 37, 37<1>, integral with the cylinder wall and piston respectively. A hollow rotary valve 46 in the upper portion of the piston is provided with a piston member 80, the lower portion of which is formed with ports 86 and engages a spring-loaded valve 79. Ports 63, 64, 65 are provided in the valve 46, and pairs of ports 66, 66' and 67, 67' in the piston 23. Under normal conditions, pressure fluid is supplied through a pipe 75 past a spring-loaded inlet valve 71 to the ports 63, 64 and is exhausted through the ports 86, the upper portion 48 of the valve 46 and return pipe 49. The fluid is applied through ports 84, 85 to the back of the piston 80 to hold the outlet valve 79 in the open position against the force of the spring 88. For steering purposes, the valve 46 is rotated in the appropriate direction by a cable 56 connected to a rack-and-pinion mechanism 52, 54 to place the valve ports 63, 64 in communication with one of the pairs of piston ports 66, 66<1> or 67, 67<1>, the valve ports 65 being put into communication with the other pair of piston ports. Pressure fluid from the ports 63, 64 passes into the cylinder chambers causing rotation of the piston 23 and corresponding movement of the landing wheel. Movement of the piston continues until the inlet ports are closed, and the wheel is then locked in the steering position. Small shimmy oscillations of the landing wheel are damped by the transfer of fluid between the cylinder chambers through restricted openings 94, 94<1>, 95, 95<1> in the valve 46. Large oscillations put the valve ports into communication with the piston ports, fluid flow taking place through the ports 63, 64 into the cylinder chambers, with consequent movement of the piston for reclosure of the ports 65. In the event of failure of the supply pressure, the inlet and outlet valves 71, 79 close, thus preventing the escape of fluid from the cylinder, which still function as a shimmy damper. A relief valve 97 may be provided in the piston below the outlet valve 79.
