Filed: 1953-03-19
Abstract: 759,019. Making tubular fittings. HUET, A. March 19, 1953 [March 28, 1952; April 21, 1952], No. 7612/53. Classes 83 (2) and 83 (4). Forging; flanging.-A method of producing a nipple or branch opening in a metal tube bend by forging the heated bend is characterized in that the forging operations comprise only compressions of metal in order not to effect any ultimate thinning of the tube wall. A tube a bent to hair-pin shape is heated on the bend, the top of which is then flattened by compressing it in the direction of arrow A. The flattening forms two shoulders C<SP>1</SP>, C<SP>2</SP> on the sides of the bend. At the point where it is desired to form the nipple a longitudinal slit H, I is cut in the flattened portion of the bend the length of said slit being equal to half the inside circumference of the nipple. The slit is opened by compression of the shoulders C<SP>1</SP> and C2 by dies d<SP>1</SP> and d<SP>2</SP> which at the same time forms the sides f of the aperture and the rim g of the nipple. A mandrel (not shown) may be used to accurately form the aperture of the nipple if necessary. Only a part of the top of the bend may be flattened in which case, the flattening pressure is counteracted by dies h<SP>1</SP> and h<SP>2</SP> (Fig. 7). A nipple having lips thicker than the wall of the bend or having an aperture greater than the diameter of the tube may be formed by increasing the compression in direction of arrow A thus increasing the thickness of metal in the region of the flattening. Alternatively the bend of the tube may initially be formed with a bulge which is then flattened. A second slit, crossing the first and of smaller length may be cut in the flattened bend to facilitate shaping of the nipple.

[Also in Division G1] The weight of a fluid pumped through a pipe 1 is determined by applying the amplified signal from a flowmeter 1, 2, to a motor 7 which is arranged to actuate cam-operated contacts 24 through a variable ratio drive, the ratio of which is controlled in accordance with the density of the flowing fluid as determined by a measurement of its dielectric constant by a capacitor in a self-balancing bridge. The contacts 24 serve to pulse a counter and give a direct indication of the weight of fluid passed. The flowmeter comprises a freely rotatable impeller around which is arranged an A.C. fed toroidal winding 3, and an induction winding 5 in which a signal of the supply frequency modulated at the impeller frequency and phase displaced, is produced, the impeller carrying at its periphery one or more diomagnetic, paramagnetic or magnetic elements which modifies the state of external fixed peripheral circuits, or one of its blades having a different magnetic permeability. Pulsations in a two-phase motor 7 due to modulations are converted to rotation by a ratchet-and-pawl device 8, and used to drive the variable ratio gear. The gear ratio is varied by a roller 20 coupled to wiper 15 of an A.C. bridge which includes density measuring capacitor 10 and is self-balanced by servomotor 18.

Abstract: 187,571. Bosch Akt.-Ges., R. Oct. 17, 1921, [Convention date]. Diaphragm horns. - In electricallyoperated horns, for example, of the type in which the diaphragm 1 is directly connected with the armature 2 of an electromagnet 3, a second note of less intensity is obtained by connecting a choking coil 8 and a second signalling key in series with the electromagnet and in shunt with the usual key. This has the advantage over the similar use of a resistance that the full current strength is available for overcoming inertia &c. when starting up, the choking coil only becoming effective to reduce the current strength when the circuit is periodically interrupted at the contacts 4. The switching in or out of the coil 8 may be controlled automatically according to the speed of the vehicle or the number of revolutions of the engine. The invention is also applicable to horns in which the diaphragm is operated by means of an air pump set in motion by an electromagnet. Specification 21823/05, [Class 40, Electric telegraphs &c.], is referred to. The Specification as open to inspection under Sect. 91 (3) (a) also states that a single circuit in which the coil 8 may be switched in or out, may replace the two shunt circuits shown. This subject-matter does not appear in the Specification as accepted.

A low voltage A.C. fluorescent lamp dimming circuit comprises, in addition to at least one arbitrarily variable control element which feeds alternating voltage to one or more lamp circuits, a separate discharge stabilizing impedance serially connected in each lamp circuit with the lamp and its source, the average impedance value of said impedance during each half period of discharge current being so arranged to depend automatically on the current flowing therethrough that it is greater in the lower current region than in the higher current region. As shown, said impedance comprises a winding 18 associated with a closed magnetic circuit core 28 which saturates at lamp currents above, e.g. one-tenth the rated lamp value, but exhibits an increasing stabilizing effect as the current is reduced, whereby to permit the lamp 10 to operate at very low current, and hence brightness, values. The higher lamp currents are stabilized by a further series connected choke winding 14 whose core 24 has an air gap and does not saturate. The discharge current is regulated by a variable voltage transformer 20 which may be common to a plurality of parallel connected lamps. The lamp 10 is shunted by an ignition device 19 and its cathodes are heated by a filament heating transformer 9. In a modification the two chokes may be embodied in a single choke whose core is, in the same region, respectively saturable and air gapped. In modifications not shown, the variable control element alternatively comprises saturable chokes, a variable resistance, or the combination of a variable voltage transformer and a variable resistance each being effective over a respective part of the dimming range; each lamp, or group of lamps, may have in series therewith a saturable transformer to provide starting voltage impulses; so-called " laminated discharge " may be prevented by a capacitive by-path shunted across any part of the circuit other than the impulse transformer alone; a resistive by-path may be shunted across the lamp; and the bypaths may be partly or wholly variable and controlled by the variable control element.

Abstract: 565,795. Wireless receiving apparatus. PHILIPS LAMPS, Ltd. May 25, 1943, No. 8343. Convention date, May 25, 1942. [Class 40 (v)] [Also in Group XXXVI] A visual indicating system for a multi-band radio receiver comprises' a cathode-ray tube having a fluorescent screen and electron beam producing elements, means to . deflect the electron beam along one axis of the fluorescent screen in incremental steps corresponding to the tuning bands of the receiver, and means to deflect the electron beam along an axis perpendicular to said first axis by an amount corresponding to the tuning frequency of the receiver, said first means being actuated simultaneously with means to change the tuning band and said second means being actuated simultaneously with means to tune the receiver through its frequency bands. As shown in Fig. 2, the vertical deflecting plates 39, 40 of a cathode-ray tube 30 are fed with a voltage from a potentiometer 50 having tappings corresponding to the wave bands of the receiver, and the switch arm 51 of which is ganged with the wave range switches 13, 17. This positions the trace vertically so as to coact with a scale (not shown) appropriate to the wave 'range in use. The horizontal deflecting plates 37, 38 are fed with a voltage from a potentiometer 150, the tapping 151 of which is ganged with the tuning means 11, 15 of the receiver. Thus, the horizontal position of the trace corresponds to the frequency to which the receiver is tuned. In addition, some I.F. energy is fed through a condenser 153 to the vertical deflecting plates so that the vertical height of the trace is an indication of carrier signal strength and assists in accurate tuning. Similarly, some audio-frequency energy is fed through condenser 160 to the horizontal deflect - ing plates so that the width of the trace is an indication of the modulation signal strength. Resistances 154, 161 prevent leakage of the I.F. and A.F. respectively. The cathode-ray tube is biassed to cut-off in the stand-by periods by means of a switch 200, 201, 202, Fig. 3 (not shown), which is operated to remove the prohibitive bias, by axial movement of the tuning knob. Alternatively, the prohibitive bias is provided by an oscillator which is rendered inoperative by the applied capacity when the hand grasps the tuning knob, Fig. 4 (not shown).
