Title: Amino acids, their extraction from vegetable and animal sources, and their employment in medicine
Inventor: KOMINATO KIYOSHI
IPC: C07D277/30
Filed: 1968-11-05
Abstract: 1,204,449. Amino acid derivatives. K. KOMINATO, and Y. KOMINATO. 5 Nov., 1968 [8 Nov., 1967], No. 52360/68. Heading C2C. The novel compounds thiocornine I (including salts and esters thereof) and thiamamidine phosphoric cysteine (exists as an open ring form IIa and as a cyclic form IIb) are obtained by hydrolysing natural protein containing materials; activated carbon is subsequently utilized whereby the thiamidine phosphoric cysteine is adsorbed thereon and the thiocornine remains in solution. Partial hydrolysis of scordinine A or B, as exemplified using 20% sulphuric acid or 15% hydrochloric acid, affords thiamacomine III which is also a novel compound. Pharmaceutical preparations suitable in the treatment of prophylaxis, for the removal of fats from the liver, for strengthening livers and also capable of acting as co-factor in a vitaminlike manner contain as active ingredient compound I or IIa (or IIb); administration may be orally, perlingually, parenterally, transcutaneously or subcutaneously.

Abstract: 1,248,339. Gripper shuttles. ADOLPH SAURER Ltd. 5 Nov., 1969 [5 Nov., 1968], No. 54140/69. Heading DIE. A gripper shuttle 7, Fig. 9, has first and second thread gripping means comprising jaws arranged so that the friction between the jaws and weft is sufficient to draw the weft through the shed but when the shuttle is picked in the opposite direction, the friction is less so that the free end of the inserted weft is tucked in and then slips from the jaws. In Fig. 9 the jaws comprise pivoted levers 21, 22, Fig. 11, with an intermediate L-shaped lever 18. In the Fig. 9 position, with a weft 8 just inserted, the lefthand jaws are opened by engagement of lever 16a with a stop 9 to engage thread 11 and the right-hand jaws are opened by the reed plate 5. On the return pick, the left-hand jaws close and the tension of the length of weft causes sufficient tension for the weft to be gripped and drawn through the shed but the small length of weft 8 in the right-hand jaws produces insufficient friction so that after being tucked in the weft slips out of the jaws. In a modification, Fig. 18, the jaws comprise a camshaped member 25 cooperating with members 29, 30, the jaws being opened by a slide cam 34 actuated by an electromagnet 36.

Abstract: 551,823. Gyroscopic apparatus. SMITH & SONS (MOTOR ACCESSORIES), Ltd., S., and MEREDITH, F. W. Aug. 8, 1941, No. 10112. [Class 97 (iii)] In a gyroscopic direction indicating instrument, in order to facilitate resetting, the gyro, the indicating member driven thereby and an adjusting member are interconnected by an epicyclic differential gear so that the indicating member is driven by the movement of the planet carrier of the epicyclic gear, and the gyro and adjusting member are arranged to drive respectively the two crown wheels which engage the planet wheels on the carrier. The azimuth ring 13 of the usual form of gyroscope rests on rollers 14 running on a normally stationary race 17 and mounted in a cage 15. The cage is connected by gearing 18 to a pointer 19 which moves in the same direction as the turning movement of the aircraft when viewed from above. When it is required to reset the pointer, a knob 21 is pressed in to free a clutch 27, 28 and is then rotated together with a worm 22 to rotate the race 17, cage 15 and pointer. If the adjusted pointer is in an awkward position for viewing against the dial 20, a more favourable position may be obtained by rotating the knob 21 with the clutch 27, 28 engaged, thereby rotating the dial 20, by means of a pinion 29, to an extent equal to the simultaneous rotation of the pointer.

Title: Field-effect transistor amplifier

Abstract: 1,215,590. Field effect transistor circuits. NORTH AMERICAN ROCKWELL CORP. 14 Dec., 1967 [14 Dec., 1966], No. 56918/67. Heading H3T. In a transistor amplifier circuit having one side of a capacitor C connected to the gate 19 of an insulated gate field effect transistor 20, a first voltage level supplied from a signal generating means #1<SP>1</SP> to the other side of the capacitor and a switch means 39 enable the capacitor to charge to a predetermined voltage, after which the signal generating means #1<SP>1</SP> supplies a second voltage level so that the voltage on the plate of the capacitor connected to gate 19 is increased so as to cause the transistor 20 to conduct and drive the output terminal 22 to substantially the voltage level supplied to a supply terminal 21 and the output terminal 22 is also connectable by a further switch means 23 to a second supply terminal 24. As shown the input 30 to a first inverter 28 is controlled by a multiphase gate having inputs #1 #1+2and a logic input 37. With # 1  negative, the input 30 is negative which turns on transistor 28. The input to transistor 18 is then zero so that transistors 18 and 23 are off. The transistors 36 and 39 conduct and the capacitor C is charged. As the capacitor C charges the source voltage 32 of the transistor 39 also varies until this transistor 39 is cut off. When the inputs  #1 , #2 change values to zero and negative respectively, the capacitor C discharges into the stray, and inherant capacitance C 1  of the transistors and the increase in voltage at the gate electrode of the output transistor 20 turns transistor 20 on. The capacitor C is then recharged when the inputs # 1 , # 2  charge. The gate electrodes of the transistors 34, 39 may be connected to the negative supply - V. In a modified circuit (Fig. 2, not shown), including the transistors 20, 23 and 39, (46, 44 and 49) the output 22 and input 26 are connected to the separate inputs of two push-pull connected output transistors (40, 42).

Filed: 1971-12-09
Abstract: 1329779 Aerials SEIMENS AG 9 Dec 1971 [21 Dec 1970] 57212/71 Heading H4A An aerial system comprises a plurality of individual radiators S which are arranged in rows and in columns. Each radiator has a digital  phase-shift element P controlled by an associated store ESP, the radio beam from the system being directed by adjusting the phase values of said elements. A vertical computer VRW computes the vertical components of the phase values, and horizontal computers HRW, one for each row, compute the horizontal components of the phase values. The components appropriate to a particular element are added together and are entered into its store. In the derivation of said components by the computers  processes of repeated addition by adders are used. As described, a radar control R provides steering information and control signals. Preferably, the computers are operative whilst transmission and reception are taking place from the aerial, after which the stores ESP become operative at the phase-shift elements P following a switching command signal. If the phase-shift elements are frequency-dependent an additional term is added in the computer adders to allow for the value of the operating frequency. As described, this involves the use of twice the number of adders in the computers as when the phase-shifters are frequencyindependent. The horizontal computers are coupled together in the manner of a shift register, as are the stores ESP of each row.
