Title: Improvements in Theatrical Appliances.
Inventor: CARTER LINCOLN JERID
IPC: A63J5/02
Filed: 1916-07-11
Abstract: 102,125. Carter, L. J. July 11, 1916. Theatrical appliances. - A theatrical appliance comprises means for producing the illusory effect of a large body of mounted troops or other mobile objects advancing towards the audience As shown in Fig. 1, successive groups A - - E of units are employed, the groups C, D, E being mounted on independent trollies. The first group A consists of painted figures 12 pivoted upon the bars of a drumlike frame 14, which may be rotated by suitable means, such as a belt 17. The figures are weighted so as to remain substantially vertical as the drum is rotated, thus producing the illusion of successive rows of cavalry men coming over the crest of a hill. The units of the second group B representing uniformed cavalry men are mounted so as to receive a succession of vertical reciprocations by means of motor-driven gearing, each row of units being out of time with the adjacent ones. In group C, the units consist of panels cut and painted to represent the head and upper part of a horse with a cavalry man astride thereof. The units are connected in pairs by horizontal rods so that a real person may stand between the units of each pair and support them by means of the rod, at the same time giving them the required oscillating movement. Group D consists of successive rows of lay figures 33 of horses, each figure having a vertical hole through the body to receive the body of a man, who, by standing on the platform 34, supports and moves the horse. A similar arrangement of man and lay figure is used in group E, but the horse is hinged to the framework by a link 37, Fig. 3. and the man standing on the platform 38 imparts the required oscillatory movement. The front legs 40 are hinged to the horse and also to the platform 38 to enhance the appearance of galloping. The recession of the ground relative to the troops is simulated by means of painted belts 41. 42 driven in any suitable manner.

Title: Improvements in or relating to piezo-electric units
IPC: H04R17/00
Filed: 1941-08-01
Abstract: 551,000. Piezo-electric instruments. BRUSH DEVELOPMENT CO. Aug. 1, 1941, No. 9850. Convention date, Aug. 2, 1940. [Class 40 (iv)] [Also in Group XL] A plate of piezo-electric material has a pair of opposite electrodes at least one of which has high electrical resistance, so that the application to the electrodes of an alternating potential at the upper end of the useful frequency range is effective in subjecting a selected portion of the crystal to a field of desired magnitude and in subjecting successively remote portions of the crystal to field strengths of progressively smaller magnitude. In practice, when used to produce a better high frequency response in loudspeakers, microphones &c., the voltage is applied at the point of maximum movement so that the remote parts of the crystal do not constitute a load on the effective part. Fig. 2 shows a loudspeaker in which a two-plate unit clamped at three corners by damping means 15, 16 has the flexing movement of the free corner 6 transmitted to a cone 2 by a link 3 passing through a flexible bushing 19. The two outer electrodes 7, 8 are connected by pieces of foil 13, 14 and a lead to one of the signal input terminals, the other of which is connected to the internal electrode 6. At least one of the electrodes has a high resistance and may be made of colloidal graphite mixed with finely divided insulating material or it may merely be a thin film of graphite. The invention is applicable to crystal units using only a single plate or having more than two plates. Specifications 366,252, [Group XL], 409,040, 454,595, [Group XL], and U.S.A.

Abstract: 1366271 Transistor gain control circuits SONY CORP 1 March 1973 [2 March 1972 22 July 1972 14 Aug 1972] 9940/73 Heading H3T In a gain control circuit signal source 1, Fig. 1, is coupled to the base of transistor 5 via resistors 2, 4; diode-connected transistor 3 provides a constant voltage bias and the gain is varied by variation of the current through resistor 4: this current is determined by means of a constantcurrent source, the current passed by it being controllable. The constant current source may comprise the collector to emitter path of a further transistor 10, Fig. 4, the base circuit of which includes diode-connected transistor 10 in series with resistor 12, in parallel with resistor 13 series-connected with variable voltage source 14. A resistor may be connected from the source 14 to the join of resistors 2, 4, so as to maintain current through the diode 3 constant (Fig. 2, not shown). In the embodiment of Fig. 4, the collector to emitter path of an auxiliary transistor 15 is connected, in series with resistor 6, its base being so biased by means of transistor 16 as to maintain the D.C. potential of the output terminal 8 constant; to this end the base of transistor 16 is biased via a resistor from the variable voltage source 14, and is also connected to earth via a diode-connected transistor 17. Alternatively, the transistor 15 may be omitted and the collector of the transistor 16 (as 15 in Fig. 5, not shown) connected to the collector of transistor 5. In a further embodiment, the signal source 1 is coupled to resistor 2 via an emitter-follower 22 and the base bias of transistor 10 is derived from variable voltage source 14 via amplifying transistor 21; the source 14 also controls a further transistor 20 whereby the current through the diode 3 is maintained constant. Instead of the transistors 20, 21 a single emitterfollower may be used (21, Fig. 7, not shown). In yet another embodiment the arrangement of Fig. 7 is combined with that of Fig. 4, so as to maintain both the current through the diode 3 and the potential of the output terminal 8 constant (Fig. 8, not shown).
