Title: Time domain equilizer and method of measuring distortions in a data transmission system
IPC: H03H21/00
Filed: 1970-04-14
Abstract: 1309951 Adaptive transversal equalizers INTERNATIONAL BUSINESS MACHINES CORP 14 April 1970 [14 April 1969] 17779/70 Heading H4R. A transversal equalizer is set up for correction of transmitted data by a test signal transmitted prior to bringing into use. The equalizer is used for a transmission system of the type in Specification 1,154,648 and 1,276,195 in which each data element is represented by a main pulse preceeded and followed by echo pulses and the data elements are transmitted in pairs with the pulse periodicity and the echo spacing being such that no main pulse coincides with any echo pulse. The equalizer comprises two delay stages De1, De2, feeding an adder SA1 from which the equalized output is obtained with the signals at the inputs to the two delay stages being fed through multiplier and sampling circuits 2, 3, to the adder SA1 to cancel prepulse distortion at the data pulse sampling instants, and the output from the adder being fed through a squaring circuit and two shift register stages T1, T2, with the output from the last stage T2, fed through multiplier and sampling circuits 5, and 6, to the adder to cancel post pulse distortion. For setting up the equalizer the equalizer is rendered inoperative, and a test signal transmitted. The unequalized signal at the output X of adder SA1 is applied both direct and via delay De3 to adder SA2, the transmitted pattern, e.g. the sequence 000111000, &c., and the delay being such that the signal at the output of SA2 is, during appropriate periods, the distortion signal only. The distortion signal is converted to digital form in A/D and applied via multiple gates Gd-2 Gd-1 Gd1 and Gd2 to set the multipliers S and R in the correction units, 2, 3, 5, and 6, the gates being operated to feed the correct distortion sample to the corresponding multiplier by the synchronizing circuit Cd, SS1, SS2, and T3, T4.

Title: Improvements in the manufacture and production of candles
IPC: C11C5/00
Filed: 1931-06-20
Abstract: Candles are made from a mixture of wax or other usual combustible with at least 2 per cent of solid, preferably saturated, aliphatic alcohols.  Suitable alcohols are those obtained by (1) the saponification of natural waxes, e.g. spermaceti, sperm oil, and carnauba, bees, montan, or shellac waxes; (2) the reduction of the acids or esters in destructively oxidized paraffin wax or in natural waxes or animal or vegetable fats or oils, e.g. linseed, castor, rapeseed, cottonseed, olive, peanut, whale, seal and fish oils, or stearine; reduction may be effected by the process described in Specification 356,731.  Other specified alcohols are tetradecyl, cetyl, octodecyl, ceryl, and myricyl alcohols, docosanol, octodecandiol, and the alcohols obtained by reducing mixtures of acids obtained as described in Specification 305,552, [Class 91, Oils &c.], by treating montan wax with chromic acid.  Usual candle-making materials specified are paraffin wax, beeswax, tallow, spermaceti, stearine, stearic acid, and fatty acids of high molecular weight obtained by the destructive oxidation of paraffin wax, middle oils and like hydrocarbons.  Examples include the use of 70 lb. of beeswax with 30 lb. of myricyl alcohol, and of 97 lb. of paraffin wax with 3 lb. of octodecyl alcohol.

Title: Improvements in or relating to electrical power supply arrangements
IPC: H04B3/44
Filed: 1940-12-20
Abstract: 546,028. Power supply for repeaters. STANDARD TELEPHONES & CABLES, Ltd., and JACOBSEN, B. B. Dec. 20, 1940, No. 17949. [Class 40 (iv)] In a system for feeding power to repeaters from a terminal station over the signal transmission line, the voltage of the 'supply current is transformed at each repeater to a higher value for transmission over the next section with the aid of a hybrid transformer and network so that variations in the load in one section do not affect the supply in another. As shown in Fig. 2, hybrid transformers TRB, TRC are associated with the loads, LB, LC &c. and with balancing resistances NB, NC &c. as shown. In a modification, Fig. 3 (not shown) each load is connected to winding c of a hybrid coil such as those shown in Fig. 2, and the power for feeding the next section is taken from a transformer connected in place of the load. Fig. 1 shows an alternative arrangement in which the three coils TRB shown are wound on the same core. The impedance Z2, Fig. 2, should preferably be a pure resistance and with this in view it may be desirable to shunt the input to station C by a condenser.
