Title: Improvements in apparatus for subjecting matter to electrical oscillations of radio frequency
IPC: H05B6/50
Filed: 1942-10-23
Abstract: 577,953. Automatic control systems. GENERAL ELECTRIC CO., Ltd., and STENNING, L. C. Oct. 23, 1942, No. 14900. [Class 38 (iv)] [Also in Group VI] In apparatus for subjecting matter to radio-frequency electrical oscillations, wherein the matter to be treated forms part or the whole of, the dielectric of a condenser which forms an'element of the tuned circuit of an oscillation generator, for example, apparatus for medical diathermy or for consolidating the adhesive in plywood, automatic frequency control is effected, in known manner by applying the generated oscillations to a filter or filters to produce an output dependent'on the frequency deviation from normal, means actuated by the filter output adjusting a variable member in the tuned circuit of the generator in a corrective sense. The variable member is preferably a condenser in parallel with the condenser characteristic of the type specified and its adjusting means is preferably an electric motor. If the frequency variations take place only in one direction a single filter having a pass-band adjacent to the normal frequency fo may be used, but, preferably, two band-pass filters having pass-bands f1-f2 and f3-f4, Fig. 2, are used to maintain the generated frequency between f2 and f3. Fine adjustment may be effected by two further filters having pass-bands f1<1>-f2<1> and f3<1>-f4<1> which maintain the frequency between f2<1> and f3<1>. The filters may be combined with a crystal controlled local oscillator of frequency F in which case the pass-bands will be f1-F to f2-F &c., thus facilitating filtering. In addition, a further filter having a pass-band f5 to f6 may be fed from the oscillation generator and its output arranged to control a switch in such a manner that the generator output is reduced when the normal frequency drifts beyond the band f5-f6.

Title: Method for maintaining a constant casting speed in continuous casting
Inventor: DREYFUS LUDWIG
IPC: B22D11/18
Filed: 1952-06-16
Abstract: 728,144. Automatic fluid level control systems. ALLMANNA SVENSKA ELEKTRISKA AKTIEBOLAGET. June 11, 1953 [June 16, 1952], No. 15064/52. Class 38 (4). [Also in Group XXII] Means for maintaining a constant casting speed in continuous casting from a tiltable receptacle, which receptacle has such a shape that deviations of the casting speed from proportionality with the tilting speed are kept within narrow limits, are characterized by a speed regulator for a tilting motor acting to keep the tilting speed directly dependent on the level of the metal surface in the mould. The top portion 3 of the mould I within which the free level of the metal is permitted to vary is cooled by a separate flow of cooling medium, the difference in temperature at the inlet and outlet of said medium being therefore substantially proportional to the height of the level surface above the bottom of the said separately cooled portion. The said temperature difference is measured by an indicating instrument 5 comprising two thermometers and a differential gear. An adjustable resistor 6 in the field circuit of a Ward Leonard generator 7 feeding the tilting motor 8, may be adjusted directly by the instrument 5 through for example a torque amplifier, or hand adjusted on a followthe-pointer system. In a modification, thermal sensitive resistors are incorporated in a bridge network. The receptacle 2 is of the type described in Specification 728,143, [Group XXII]. The Provisional Specification refers to the use of tilting motors of the Schrage type.

Title: Improved compensating arrangements for electrical circuits involving inductance
IPC: H01F27/00
Filed: 1945-06-14
Abstract: 593,632. Resonant circuit compensating devices. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., and BRAILSFORD, J. D. June 14, 1945, No. 15144. [Classes 40 (iii) and 40 (v)] [Also in Group XXXV] Compensation for variation of frequency in a resonant circuit due to changes in temperature is effected by altering the inductance of an auxiliary coil which is coupled to an inductance in the resonant circuit. The change in inductance of the auxiliary coil which may be in the form of a flat spiral, is effected by means of a metal damping plate which moves relative to the coil owing to the action of a bimetallic strip under a change in temperature. In Fig. 3b, the bimetallic strip bm which is composed of brass and " Invar " (Registered Trade Mark) acts as the metallic damping plate, and effectively varies the inductance of the auxiliary coil ac. In addition, for the purpose of compensating for changes in the capacity elements of the resonant circuit, a condenser may be formed by means of the fixed plate fe and the bimetallic strip bm, the capacity of which is caused to vary with temperature. The circuit shown in Fig. 4 is an example of the way in which the compensator unit may be connected in a resonant circuit, the coil l coupling the auxiliary coil ac with the main, inductance coil L. In a multi-range receiver with appropriate switching arrangements, a number of coils l may be used, to effect compensation in respect of an equal number of main inductance coils L, the ratio of the windings concerned being adjusted in each case to give the required compensation effect for the temperature coefficient of the coil concerned. The surface of the " Invar " side of the brass "Invar " metallic strip is arranged to face the auxiliary coil, and this surface may be thinly coated with silver. Specification 475,104, [Group XXXV], is referred to.

Filed: 1955-05-31
Abstract: 785,483. Binding edges. PRIME MANUFACTURING CO. May 31, 1955, No. 15495/55. Class 42 (1). [Also in Group VII] A machine for presenting and attaching a binding strip to a marginal portion of the surface and to the peripheral edge of a sole blank with a portion of the strip upstanding around the perimeter has a freely rotatable binding strip supporting roll 18 to position and support the strip, a bevelled roll 23 the bevelled surface whereof supports the sole blank from beneath and applies the strip to the surface of the sole, and an edge gauge roll 24 to engage and press the binding strip into a right-angle position relatively to the supported surface of the sole and into contact with the edge of the sole. In operation the sole blank 50 is supported on an adjustable roll 23 freely rotatable about an axis inclined at 45 degrees to the horizontal. The binding strip 51 is supported and positioned by an adjustable flat roll 18 which is free to turn about a horizontal axis and engages the bottom edge of the strip, the end of the strip being caught between the edge of blank 50 and a gauge roll 24 rotatable about a vertical axis, the upstanding portion of the strip being caught between roll 24 and the rim of roll 23 to urge the vertex of the strip into a right-angle formation beneath the sole. A deflector 25 on roll 24 turns over the marginal portions of the strip into the range of a feeding foot 12 driven by eccentrics on shaft 9. The machine is then set into operation and foot 12 advances the sole away from the operator strip 51, which is adhesively coated on the flange 51<SP>1</SP> and other blank contacting portions, being progressively attached to the blank. The machine is stopped when the attached end of the strip is in proximity to blade 38. Handles 37 and 43 are then depressed against the pull of spring 32, to raise blade 38 about axis 30 and swing it outwardly about the inclined axis of boss 35 into contact with the attached end of strip 51. Handle 43 is then swung upwardly, against spring 44, to sever the band at a gauged point so that it will exactly butt the attached end. When the handles are released springs 32 and 44 return them to positions determined by the adjustable stop screw 33 and the engagement of bolts 42 on one blade member with the ends of slots in the other blade member. The machine is restarted to attach the free end of the strip. The auxiliary frame 13 carrying the blades &c. may be pivoted about shaft 46, against the pull of a spring, for the introduction and removal of work.

Title: Improvements in or relating to road signalling apparatus
IPC: G08G1/08
Filed: 1929-03-26
Abstract: 332,333. Waller, J. E. March 26, 1929. Road signals.-Relates to signals at road junctions adapted to be actuated automatically by treadles depressed by the vehicles. Caution and danger signals on a column 21 at a point where a side road meets a main road are given successively for predetermined periods by means of a time-lag device actuated by the depression of a road treadle which lifts a member 38 so as to complete an electrc circuit energizing a solenoid 47 in the road column 21. Toggles 48 are thereby actuated together with a pivoted operating arm 50 geared to the pivoted contact arm 51 of a switch for uni-directional operation thereof. By this device depression of the treadle causes the switch arm 51 to move from contact 51a to contact 51<c>, thus completing the circuit for a caution lamp 45 behind amber-coloured glass 45<a>. As soon as the vehicle has passed the treadle, the switch rod 38 falls and the core of the solenoid also falls under the control of a dashpot 49. After a predetermined interval the contact arm 51 leaves the contact 51<c> and engages the contact 51b, thus lighting the red danger lamp 46 for a certain period before the arm 51 returns to the contact 51<a>. A lamp 44 illuminates a. direction indicator 43 having at the sides stencilled sheets and at the end danger signs. Tumbler switches 56, 58<a>, 58<b>, 58<c> may be operated to cut out any of the signals. Fig. 3 shows on a larger scale the arm 50 operating through gears 66, 67<a> a spindle carrying a striking-plate 68 with rollers 69, 70 thereon. A coiled spring 72 having one end anchored to the plate 68 and the other to the contact arm 51 causes the latter to move with the plate but permits relative movement therebetween. When the solenoid core raises the arm 50, the arm 51 is rotated past the contact 51b to engage the contact 51<c>, in which position a roller 76 on a catch 73 engages a notch 77. During the subsequent return of the striking plate 68 to normal position, the arm 51 cannot be moved until the roller 69 disengages the catch roller 76, whereupon under the tension of the spring 72 the arm 51 engages the contact 51<b>, the roller 76 engaging a notch 78. The arm 51 remains in this position during the continued return of the plate 68 until the roller 70 engages the catch and disengages the roller 76 from the notch 78, when the arm 51 returns to normal position.
