Patent GB-1104528-A (GB)
Title: Sausage casings
IPC: A22C13/00
Filed: 1966-10-10
Abstract: A shirred sausage casing is mounted over a tube of flexible material that is sealed at each end and that extends beyond each end of the casing, said tube having been so inflated that an air cushion of greater diameter than the casing is formed at each end, such that when the casing is swollen, as by immersion in water, prior to filling, the cushions prevent any substantial elongation and loss of shirring.  Desirably one end of the sealed tube has a weakened rupture point, such that when the swollen assembly is forced over the stuffing horn, the increase in pressure ruptures the tube, which may then be withdrawn from the free end of the casing, which is thereafter closed.

Title: Transmission systems
IPC: H04L25/03
Filed: 1963-11-21
Abstract: 1,009,491. Telegraphy. INTERNATIONAL BUSINESS MACHINES CORPORATION. Nov. 21, 1963 [Dec. 18, 1962], No. 45923/63. Heading H4P. In a data transmission system in which the data is distorted prior to transmission to compensate for line characteristics, undistorted test pulses are transmitted initially and sampled at bit frequency at the receiver, where they are received distorted. The results of the sampling are returned to the transmitter where they are used to predistort the data to be transmitted. In a first embodiment, a distorted test pulse received from line 14 passes to unit 26 which senses the main peak and, via unit 29, enables gate 36 at the first peak in the distorted pulse. Unit 26 also generates bit rate clock pulses which step binary counter 34. After a K- bit delay (K = number of bit periods up to the maximum peak) the distorted pulse arrives at comparator 40. Comparator 40 is enabled at bit rate except during the main peak time and, when the distorted pulse differs from a certain potential, inhibits gate 36 via unit 29 and also passes a positive or negative pulse, indicating the sign of the difference, to register 46. Unit 48 now reads out the register, which also holds the binary count on counter 34 at the time the comparator pulsed, and the register's content is passed at slow speed to the transmitter where, by means of units 52, 60, 62, it modifies the next test pulse to be sent. This operation continues until counter 34 reaches full count, whereupon data may be transmitted, it being predistorted by units 52, 60, 62. A second embodiment, Fig. 2 (not shown), uses two comparators for positive and negative thresholds, the thresholds being gradually reduced to zero and the test pulses modified until the comparators give no output at each enabling pulse. Specification 1,009,493 is referred to.

In this construction the cylindrical faces only of insulator 5 need be metallized for soldering, and also, by suitable choice of angle α, preferably 35 to 60 degrees, in connection with the thermal expansion coefficients of components 1, 2, 3 and 4, the cathode to control electrode distance is near constant over large temperature variations and also the influence of mechanical tolerances in manufacture is minimized; strips 3 may have impressed grooves between bending points, or may be thin wires with depressions at the bending points to reduce the rigidity thereat. Cylinder 8 which may have two, preferably three tongues secured at 20, may be less than 25 Á thick to yield a short heating-up period, its radiation losses preventing excessive heating of the cathode, further reduction being obtained by reducing the cylinder length and blackening the outer surface of cylinder 8, support 1 and inner face of cylinder 4; cylinder 8 also serves as a metal vapour shield. Strips 3 may be of nickel-iron or nickel-iron-molybdenum, cylinder 4 of fernico, insulator 5 of pre-pressed glass, crystallized glass, or fusible ceramic material of 50% by weight of Al 2 O 3  and 50% by weight of an equal parts mixture of CaO and B 2 O 3 .

Filed: 1975-11-19
Abstract: 1509598 Automatic voltage regulation NORTH ELECTRIC CO 19 Nov 1975 [13 Dec 1974] 47679/75 Heading G3X A ferroresonant voltage regulator includes a transformer core with first and second magnetic paths each carrying a capacitor winding, a primary winding coupled to an A.C. source, and a secondary winding coupled to a load. The source is decoupled from the secondary winding, and the two capacitor windings are also mutually decoupled. A switching device operates in different half-cycles to connect a capacitor to the respective capacitor windings, thereby reversing the charge on the capacitor. As shown in Fig. 1, an A.C. source 12 is connected through a linear decoupling inductor Lp to primary windings N p1 , N p2  on core portions 40, 41 decoupled by magnetic shunts 43, 44, Fig. 2. Windings N L1 , N L2  are connected to a load circuit 20, and capacitor windings N C1 , N C2  are connected in series across a ferrocapacitor C. A control circuit 22, which may be influenced by a feedback connection 46A, fires thyristors SW1, SW2 in alternate half-cycles to place the capacitor C in series with each of the windings N C1 , N C  2  in turn, and thereby control the regulated load voltage. The independent decoupling provided by the inductor L p  and the shunts 43, 44 enables the switching action to be controlled to reduce high peaking currents, losses and noise. In another embodiment, Fig. 4, (not shown), the capacitor C and thyristors SW1, SW2 are connected across portions of the primary windings. Additional windings provide an input for a thyristor control circuit including amplifiers and switching transistors, Fig. 5, (not shown).
