Title: Manufacture of physiologically active substances from the anterior lobes of the hypophysis
IPC: A61K38/24
Filed: 1928-05-23
Abstract: 291,018. I. G. Farbenindustrie Akt.- Ges. May 23, 1927, [Convention date]. Medicines for internal use.-Two active substances, having opposite effects on the female sexual organs, are obtained from the anterior lobe of the hypophysis by extraction with organic liquids and with aqueous solvents respectively. When an organic solvent miscible with water is used, for instance acetone, the gland is extracted first with this and the residue then extracted with water, physiological salt solution, Ringer's solution. or the like. The separate extracts are each purified in the usual manner and that obtained by the use of the organic solvent may be freed from solvent in a vacuum and again dissolved in aqueous diethylin. A known process wherein the gland is extracted with alcohol diluted with water is also referred to. In the Specification as open to inspection under Sect. 91 (3) (a) it is stated that when, using solvents immiscible with water, such as ether or ligroin, the gland may be treated simultaneously with the two solvents, and also that alcohol may be used in place of acetone. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to cathode ray tube optical data scanners
IPC: G06V10/10
Filed: 1970-04-01
Abstract: 1,241,404. Character recognition. SIEMENS A.G. 1 April, 1970 [2 April, 1969], No. 15356/70. Heading G4R. [Also in Divisions G2-G3] In a cathode-ray tube optical data scanner of the type wherein a lens 6 forms an image of the tube light spot in the plane of a data carrier 3, which reflects light from a read-out field 4 to photo-electric transducers 7, 8 whose summed video signals are passed to an A/D converter 12, light-receiving elements 14 are placed in a viewing position relative to the tube screen corresponding to the position of the transducers 7, 8 relative to the read-out field 4, the combined output of elements 14 are passed to a photo-electric transducer 15 to form a control signal which is compared in a control circuit 16 with a reference signal, and the error signal so produced is used to control the radiation intensity of the tube 5 so that the control signal is maintained as closely as possible to the reference signal. The control system prevents the occurrence in the signals from transducers 7, 8 of undesired modulations caused by the differing sensitivity of the transducers for different angles of incidence of the light. These modulations are compensated by the control system so that the signal supplied to the circuit 12 only contains disturbances produced by the differing reflective properties of the data carrier 3. The geometry of the system containing members 3 ... 6, 7, 8, 14 is analysed to explain how the signals from members 7, 8, 14 are modulated in accordance with the same law relating the various angles and distances of the system, Fig. 2 (not shown). Members 14 may be optical conductors or photo-electric transducers such as electron-multipliers. Members 7, 8 may be replaced by a system similar to members 14, 15. The control circuit 16, Fig. 3 (not shown), comprises a differential transistor amplifier supplied with the control and reference signals and controlling the grid of the tube 5 via the supply 20. The circuit 16 also includes an auxiliary circuit to override the signal from the amplifier so that the tube may be dark modulated at predetermined instants. The scanner scans two data-carrier transport paths alternately.

Title: Improvements in and relating to electric remote control systems
IPC: H02J13/00
Filed: 1928-05-31
Abstract: 291,385. British Thomson-Houston Co., Ltd., (Assignees of Stewart, C. E.). May 31, 1927, [Convention date]. Selective distant control systems.-In an electric remote control system a device may be operated for a predetermined time duration in response to an actuating current impulse. For example, the contact arm of the field rheostat of a dynamo-electric machine may be moved from one contact to the next by an electric motor when an actuating impulse is transmitted from a distant control station. The Fig. shows a selective system employing synchronously rotated distributors 1, 2 located at the control and remote stations A, B respectively, and adapted to associate successively control switches 11, 14 with corresponding polarized relays 31, 32 over a common line wire B. The relays 31, 32 are adapted to control a motor 29 in one or the other direction to vary the resistance 24 in the field circuit of the generator 25. When the operating member 22 of the switch 11 is actuated the contacts 10, 19 are closed. The contacts 10 mark a segment 12 on the distributor 1. so that when the distributor arms engage the marked contact and the corresponding contact 33 on the distributor 2 a circuit is closed for the relay 31 from the battery 7 over relay 8 and line wires 3. 4. The relay 8 closes the circuit of the lamp 16 over contacts 19 to signify that the impulse has been transmitted. The relay 31 operates its contacts 33, 34, the former of which energizes relay 37, which energizes a slow-release relay 41. The relay 41 closes the motor circuit over one field winding 44 and the contact arm 27 of the field regulator 24 is driven in the appropriate direction. Simultaneously with the closure of the motor circuit, the relay 31 is energized by reverse current over the contacts 34 and is reset. The relays 37, 41 are thereby de-energized, the time-delay mechanism 50 associated with the relay 41 maintaining closed the motor circuit until the regulator arm 27 engages the succeeding contact. Actuation of the switch 14 at the control station causes operation of the relay 32 to drive the motor 29 in the reverse direction for a predetermined time period through the intermediary of the relays 53, 54.

Title: Automatic Photographic Exposure Control System
Inventor: HARVEY DONALD MALCOLM
IPC: G03B15/04
Filed: 1969-03-27
Abstract: 1,198,966. Exposure control. EASTMAN KODAK CO. March 27, 1969 [April 1, 1968], No. 16035/69. Heading G2A. In an exposure control system for a flash camera, the diaphragm is opened continuously as the flash is fired until a specified opening is reached, the exposure being terminated by closure of a shutter. As shown, the diaphragm is formed by two sliding vanes 1, 2, each having a V-shaped cut-out 4, 5 respectively. As the vanes slide in opposite directions, the cut-outs define a gradually increasing aperture 3. The vanes are actuated by a lever 7 having a pin 6 which engages in respective slots 8,9 in the vanes. Lever 7 is normally latched Fig.2 (not shown) against a spring (15) by a camera release 13. When the release is pressed, the flash is fired and simultaneously the lever 7 is unlatched so that the vanes commence to open the aperture. Lever 7 rotates about a pivot 11 which forms one pole of an electromagnet 10, and the free end of the lever carrying the pin 6 slides across the other pole 12. The flash light reflected from the subject being photographed is received by a photo-cell P, and when this light reaches a predetermined intensity, a switch SCS is closed which completes the energizing circuit for the electromagnet. As this is energized, the free end of lever 7 is held by pole 12, and can slide no longer, so that the increasing aperture is arrested at that particular value. A shutter blade (16) is used solely to terminate the exposure, being cocked to an open position prior to exposure, and operates at a fixed speed. In the modification of Fig. 5 (not shown) the shutter is a variable speed shutter, and when the photo-cell is triggered by a sufficient light intensity, it releases the shutter, instead of arresting the diaphragm.

Abstract: 1,094,437. Weighing apparatus. CARL SCHENCK MASCHINENFABRIK G.m.b.H. April 12, 1966 [April 10, 1965], No. 16046/66. Headings G1N and G1W. A vehicle weighing apparatus includes a pair of parallel track members 1, 2 for supporting wheels of the vehicle, each member being pivotally supported with respect to a base 11 and resting on a load cell 16, 17 at a point displaced from the pivot point 12, 13, each pivot point being aligned with the load cell associated with the other track member on a line perpendicular to the track members. Links 20, 21 extend transversely between each track member and the base to prevent horizontal movement. In the arrangement described two pairs of track members are spaced apart for supporting all the wheels of a fourwheeled vehicle, and the load cell outputs are added together when the vehicle is stationary. Two circuit arrangements are described for computing the weight of a vehicle moving at a constant speed over the track members. In both cases the outputs from one pair of load cells 16, 17 are differentiated, the original and differentiated signals are stored in memory units 31, 33, 35, 37 and the differentiated signals are added. In Fig. 3 the output from adder 40 is divided by the differentiated signals at 41, 42 and the resulting quotients are multiplied by the corresponding load cell outputs at 43, 44 to give a pair of signals which are added to those resulting from a similar computation involving the second pair of load cells. In Fig. 4 (not shown) the load cell outputs are divided by the differentiated signals, the two resultant signals are added (at 53) and the outputs from this adder (53) and the adder (50) which sums the differentiated signals are multiplied together (at 54). The product is then added to the corresponding product from a computer connected to the second pair of load cells. In both embodiments the load cell outputs are also differentiated a second time and the values of the load cell outputs and the first derivatives are not stored until the second derivatives fall to zero, when oscillations have been damped out.
