Title: Improvements in and relating to mains-operated wireless receiving apparatus and the like
IPC: H01Q1/46
Filed: 1930-01-14
Abstract: 346,780. Wireless receiving systems. SAVAGE, L. F., 20, Old Compton Street, London, WRIGHT, E. H. M., Limberloft, Coppice Drive, Wraysbury, Buckinghamshire, and RADIOVOLT, Ltd., Kingston Road, Staines, Middlesex. Jan. 14, 1930. Nos. 1364, 14856, and 16082. [Class 40 (v).] In a mains-operated wireless set, one or more of the conductors a of the mains is used as an aerial and another a<1> as an earth. A mains transformer b has two secondaries supplying respectively the high- and low-tension currents, and the aerial and earth connections to the mains are made in parallel with the transformer through two condensers c .. d<1> in series, the one adjacent the mains of high capacity and the other of relatively small capacity. Alternatively a single fixed or variable condenser of small capacity is included in one or both connections (Fig. 2, not shown). To improve the selectivity an auxiliary aerial consisting of a wire or a metallic plate or the like is connected to the aerial circuit. According to modifications the connections to the mains are made indirectly through a high-frequency transformer, Fig. 3 (not shown), or an autotransformer, Fig. 4 (not shown), in series with a condenser, or to a potentiometer, Fig. 5 (not shown), or to the middle point of two resistances or two condensers in series in shunt across the mains, Fig. 6 (not shown).

Title: Deskewing Systems for Stored Data
IPC: G11B5/008
Filed: 1968-01-10
Abstract: 1,193,243. Deskewing systems in electric digital data-storage. INTERNATIONAL BUSINESS MACHINES CORP. 10 Jan., 1968 [13 Jan., 1967], No. 1369/68. Heading G4C. A deskewing system for reading a group of data bits recorded on plural channels of a record moved stepwise, detects generated clock pulses in response to the first bit read to define a reading cycle in which sensing can occur, each channel having means responsive to sensing of a data bit to inhibit sensing of a further data bit in the channel in the same cycle. A parallel 3-bit character recorded in NRZ or NRZI form is read from an incrementallystepped magnetic tape by dual-gap read heads 20, 22, 24 in respective channels A, B, C. Positive and negative pulses (which should occur alternately) in each channel are routed by a phase splitter 40 to charge integrators 44, 46 respectively. When an integrator charge reaches a threshold, a respective Schmitt trigger 48, 50 is set, setting of either trigger in a given channel resetting the other trigger in the channel. Setting of either trigger sets a bit skew register 54, 60 or 64 for the channel. If two adjacent pulses of the same polarity are produced by a head, the second (spurious) pulse is ignored since it merely attempts to set a Schmitt trigger which is already set. The integrators are discharged and disabled (squelched) when the respective channel skew register 54, 60 or 64 is set (SQUELCH A, B, C) and during the low speed portions of the tape step executed to read the character (SQUELCH M) and when a character is in the skew registers 54, 60, 64 (SQUELCH D). A READ signal from a central processing unit will produce a step via AND 68 if the SQUELCH D signal is absent, the STEP signal also causing a gated multivibrator 76 (utilizing a multivibrator, a counter and logic) to produce the SQUELCH M signal and when this is absent a sequence of six clock pulses dividing up the portion of the step during which a character may be sensed. When the first sensed 1 bit arrives in a skew register 54, 60 or 64, OR gate 83 produces a 1st BIT signal which gates the remaining clock pulses via AND 88 to be counted at 90. A count of 3 sets latch 98 which permits AND 72 to produce the SQUELCH D signal at a count of 4. The SQUELCH D signal besides its above functions, also, via AND 70, gates the skew registers 54, 60, 64 at 84, 85, 87 to a tape control unit which then resets the registers and latch 98. In a modification, SQUELCH D is generated at the third or fourth clock pulse after the first bit occurs according as the first bit occurs early or late in the step respectively. In a further modification, two steps are used to read each character and the clock pulses are unequally spaced to allow for the way tape speed changes during each step.

Title: Improvements in or relating to electric motors for driving rotary apparatus
IPC: H02P5/753
Filed: 1929-01-16
Abstract: 328,019. Wright, G. M. Jan. 16, 1929. Machines with two or more armatures ; driving arrangements. - An electric motor, particularly for driving picture telegraph apparatus, comprises two combined synchronous and continuous current motors, the carcase of one combined motor being driven by the rotor of the other. The continuous current elements supply most of the power while the synchronous elements serve to ensure that the correct speed is accurately maintained. As shown, the shaft A1 which drives the rotary optical system of a picturetelegraph apparatus carries one element of a synchronous motor SM1 and one element of a continuous current motor SM2. The other elements of these motors are carried by a carcase C which also carries elements of a second synchronous motor SM2 and a continuous current motor DC2. The carcase C2 of the second combined motor is fixed. For low speeds of the shaft A1, the carcase C rotate in opposite directions. The synchronous part of one of the combined motors may have 114 pairs of poles and the other 115 pairs of poles, both being energized with current having a frequency of 200 cycles per second. If the current is drawn from a frequency multiplier, the shaft speed may be varied by obtaining the alternating current from a different stage of the frequency multiplier. Alternatively, the synchronous motor elements may have the same number of poles, in which case they are supplied with currents of different frequencies, for example 2000 and 1950 cycles per second respectively. The two frequencies are preferably interdependent and may be obtained from a low frequency tuning fork generator or by applying the beat frequency between two slightly different tuning fork generators to a frequency multiplier from which the two high frequencies are supplied.

Abstract: 836,406. Corrugated flexible tubing. HOOVER Ltd. Jan. 19, 1956 [Jan, 31, 1955], No. 1912/56. Class 99(2). In a flexible extensible corrugated hose particularly for a suction cleaner the resilient helical reinforcing coil is bonded to the tube wall of thin elastomeric material over a part of the length of the hose. The hose is generally similar to those described in Specifications 784,060 and 800,371 and may be manufactured in a generally similar manner. In the Figures the reinforcing coil 11 is bonded to the hose 10 of thermoplastic elastomeric material such as polyvinyl chloride over the end portions B (one end only shown) but is not bonded to it over the major part A of the hose length. The coil 11 is of spring wire 12 sheathed or coated in a covering of thermoplastic elastomeric material 13 preferably the same material as the hose 10. The coil 11 is prestressed so as to tend to close up when free to do so. The mandrel on which the stretched coil is placed may be inflated to clamp the coil in position with the turns distributed either uniformly or non uniformly. Prior to positioning of the radially stretched thermoplastic tube 10 over the coil appropriate areas of the coil are coated with a solvent for the material of the sheath and tube. The solvent or a cement for the thermoplastic material may be sparingly applied to the reinforcing element so as to be confined to the areas to be bonded. Alternatively the hose carcase may be retained in its stretched condition until the solvent or cement has had an opportunity to evaporate or dry. Specification 836,407 also is referred to.
