Title: Improvements in or relating to loudspeakers having a conical diaphragm
IPC: H04R1/22
Filed: 1951-10-03
Abstract: 722,263. Loud-speakers. GENERAL ELECTRIC CO., Ltd., and BRITTAIN, F. H. Sept, 19, 1952 [Oct. 3, 1951], No. 23045/51. Class 40 (4). In a loud-speaker having a conical diaphragm, a rigid plug occupying between 10 and 20 per cent of the volume of the diaphragm cone is disposed within the boundaries of the cone, and at least a portion of the plug is in the form of a cone having the same angle as the diaphragm and extends from the apex of the cone with its curved surface close to the diaphragm. The presence of the plug is said to smooth out the frequency response of the loud-speaker. Plug 5, Fig. 2, comprises two cylinders 8, 9 joined by a conical portion 10 and the lengths of the cone and outer cylinder found to give the optimum result are stated to be 15-25 per cent and 50 per cent of the depth of the diaphragm, respectively. The distance between the conical plug surface and the diaphragm is said to be critical and limits of <1>/16 to <1>/4 inch are given in connection with a 6-inch metal cone. The plugs which may be of wood, metal, or plastic may be hollow provided that hollowing does not give rise to undesirable resonance. Specifications 461,073 and 604,159 are referred to.

Abstract: 534,931. Drawing and rolling mandrels. NAAMLOOZE VENNOOTSCHAP WALLRAMIT HARDMETAAL MAATSCHAPPIJ. Aug. 10, 1939, No. 23115. Convention date, Aug. 11, 1938. [Class 83 (iv)] Tube drawing or other mandrels with hard metal heads have the heads connected to the mandrel rods by flexible intermediate parts so as to avoid cracks in the head caused by deflection of the rod when suddenly relieved of load upon the drawing over of the tube and to allow it to yield to irregular wall thickness or hard bodies in the tube. The head 2 may be screwed on a headed shaft 1 and soldered to a tubular member 7 and an intermediate part 3 formed with a ball end 4 lying in a recess in a sleeve 5 screwed in the mandrel rod. The ball ended part 3 may be replaced by a flexible wire cable. In a further form the cable 8 is surrounded by a spring 11, Fig. 3, so as to return the head elastically into its initial position. In another form the head may be directly secured on the flexible cable. The Specification as open to inspection under Sect. 91 states that the mandrel may be used for rolling. This subject-matter does not appear in the Specification as accepted.

Abstract: 1302573 Mixing liquids EATON YALE & TOWNE Inc 13 May 1970 [15 Sept 1969] 23227/70 Heading B1C [Also in Division F2] A carbonated beverage dispensing apparatus, comprises feeder and valve assemblies 12 and 10 respectively, which are releasably securable together and which when so secured afford separate and controlable flow paths for the beverage and the soda into a mixing and delivering spout 17, the spout being releasably attached to the valve assembly 10. The feeder assembly is formed with two supply ducts, only one being shown, which are closable by engagement of a ball check valve member 40 with its associated seat 44 when the feeder and valve assemblies are separated from one another. The valve assembly is formed with two projecting hollow ducts 60, only one being shown, which lead to respective valving chambers 18f and 19f with the outflow from such chambers being controlled in the first instance by electromagnetically operable valves 13 and 14 respectively, and in the second instance by throttling valves 140 and 120 respectively, the outflow from the last mentioned valves leading to the spout 17. When mounted one against the other, the projecting ducts 60 of the valve assembly 12 each enter within one of the two check valve seats 44 of the feeder assembly so causing the two check valves to be unsealed. Simultaneously, a clamping arrangement, constituted by a cam 66a on the valve assembly 10 and a spring-urged arm 70 on the feeder assembly 12, becomes operative to retain the assemblies 10 in mutual engagement. With both electromagnets actuated, as by engagement of a paper cup with a lever 15, beverage flows from chamber 19f, through throttling valve 120, which valve is adjustable relative to a housing plate 67 and has a passage 19j extending to entire length thereof, and into the spout 17. Simultaneously, soda water flows from chamber 18f, through throttling valve 140, which valve is composed of a plurality of plates 152 interposed between mutually adjustable cup-like retainers 150, 151, and into the spout 17. If desired, operation of a switch 15b overrides the compound electromagnet actuating circuit to ensure actuation of electromagnet 13 only and hence dispensing of soda water only.

These spacers 13, 14 comprise mica discs apertured to receive the indirectly-heated cathodetube 12 and the support rods of the grid 10, the disc 14 resting on a shoulder of the tube 15. The electrodes 151, 10, 12 are assembled as a unit which is mounted by spot-welding on rods 8, 9 in the foot 3, and the lead 6 to the grid 10 is connected to a top terminal 5. The grid 15<1> is of helical wire or metallic mesh. The anode 20 partially surrounds the grid 15<1> and is provided with a slot by a 27 bridged U-shaped conductor 26 of higher resistance than the anode so that the grids and the tubes 7, 15 can be heated by high-frequency currents without overheating the anode.

A vehicle tyre valve provides for independent inflation, deflation and gauging of each of the chambers of a safety tyre and comprises a hollow stem having a valve core at its outer end and being movable to connect its inner end with a selected one of the chambers. Stem 13 (Fig. 2) carries a valve core 43 and is rotatable about its longitudinal axis from the neutral position shown to cause blade 42 to open one of a pair of auxiliary valves 28 or 27 (Fig. 4, not shown) which connect chamber 22 with inner and outer tyre chambers 9, 10 (Fig. 1, not shown). A rubber spring 34 and a projection 36 engageable with notches 19, hold the blade in its adjusted position. In a modification (Fig. 6) valves 27, 28 are replaced by passages 61, 62 in rubber block 60, and rotation of an eccentric 58 on hollow stem 67 effects selective closure of these passages which are connected by bores 63, 64 with the tyre chambers. In another modification (Fig. 7), stem 78 normally communicates with one tyre chamber via the path shown in solid arrows, but when the stem is moved to the left, closure member 89 seats an inner stem 86, and projection 82 opens auxiliary valve 85 to establish communication with the other tyre chamber. A pin 76 moves along a notched slot 73 to retain the stem in its adjusted positions. In Fig. 9, a rotary stem 110 carries a pin 105 which is movable into engagement with a selected one of four auxiliary valves 113-116, each connected to separate chambers in a tyre or other inflatable device.
