Title: Apparatus for measuring electrical admittance
Inventor: WOODS DONALD
IPC: G01R27/02
Filed: 1950-05-09
Abstract: 681,927. Electric measurements. NATIONAL RESEARCH DEVELOPMENT CORPORATION. May 9,1951 [May 9, 1950], No. 11574/50. Class 37. Apparatus for the measurement of electrical admittance at high frequency comprises two T-networks in parallel, the shunt impedances being adjusted so that the algebraic sum of the transfer impedances of the two networks is zero, giving zero transmission through the combined networks. Each T-network contains fixed series arms C1, C2, C3, Gs (Fig. 2), and a variable calibrated capacity Ca, Cb in the shunt arm. Zero transmission is obtained with and without the impedance to be measured connected across terminals T, T1, and expressions are derived for the reactance and resistance of the unknown impedance in terms of the known series arms and the change in the capacities of the variable condensers Ca, Cb. In an embodiment (Fig. 3), the variable condensers Ca, Cb are made to follow a linear law and are controlled by vernier micrometer heads 1, 2, parallel trimmer condensers Cat, Cbt being controlled by knobs 3, 4, 5 and 6. A shunt inductance Lb is added to one T- network by parallel plug-in coils 9, 10. All the components are located in cavities in metal blocks 18, 23 with facilities for the initial adjustment and replacement of the fixed series arms by removing caps 12, 13, &c., and are interconnected by a coaxial line system so as to give zero coupling. External connections are made via, coaxial terminals 15 to the unknown impedance, 16 to an A.C. source, and 17 (on the underside of block 18) to a detector. Possible sources of inaccuracies are discussed, and how they may be overcome to give a high degree of accuracy.

Title: Improvements in the manufacture of food compounds
IPC: A23L7/20
Filed: 1931-04-20
Abstract: A food preparation is obtained by admixture of a cereal wort, milk and a fruit material, a partial digestion of the proteins of the cereal and milk being effected by means of a proteolytic ferment or ferments prior or subsequent to addition of the fruit material thereto, the product being finally reduced to dry powdered or other highly concentrated form.  In an example, a mixture of equal parts of wheat flour and barley malt or malt flour, and 4-5 times as much water is gradually heated to and then kept for about 15 mins. at 150-155 DEG  F. and subsequently at 170-175 DEG  F. to convert the starch into maltose and dextrin and render soluble some of the insoluble albumenoids.  Milk and pineapple are then added, preferably 2 lbs. of fresh milk and 1 lb. of ripe pineapple in small pieces for each pound of malt and wheat flour used.  The mixture is stirred and digested for 1 1/2 -3 hours at about 120-130 DEG  F., the enzymes, especially the bromelin, present in the pineapple converting the proteins into more soluble and readily digestible forms, and is then evaporated and ground to a fine powder.  The product may be added to water or milk to form a beverage.  The milk may be homogenized before use, and may be concentrated or condensed.  Fresh pineapple juice may be used as the fruit constituent, 1/4 pint to each 2 lbs. of fresh milk.  Other proteolytic ferments, e.g. pepsin or pancreatin, may also be added in small amount. Fruits such as peaches, strawberries, raspberries, &c., may also be employed, and if used without the pineapple, proteolytic enzymes such as pancreatin or pepsin are added.  When pancreatin is used the fruit is not added until after the digestion.

Abstract: 554,596. Automatic control systems for gyroscopes. AUTOMATIC TELEPHONE & ELECTRIC CO., Ltd., SMITH, S. R., GRAHAM, J. ST. C. W., and LAWRENCE, C. F. July 16, 1940, No. 11748. [Class 38 (iv] [Also in Group XX] Alignment.-A gyroscope compass in which the frame 13 is maintained in constant relation with the gyroscope 10 by a reversible electric motor 20 has means whereby the motor operates at a higher speed when the angular deviation exceeds a predetermined value. The frame is normally kept hunting by a relay 21 energized to reverse the field of the motor by a contact arm 31 engaging one of two contacts 70 on the frame ; a resistance 42 in the armature circuit of the motor reduces its current consumption. A contact arm 38 is frictionally driven by the frame 13 when it turns in relation to its support and makes contact at 39 or 40 to short circuit the resistance and increase the motor speed when this turn exceeds a predetermined amount e.g., on change of course of the craft. Contacts 55 operate before the contact 38 in opening the short-circuit. In a modification the arm 31 may engage contacts one on each side of the contacts 70, whereby a second relay may operate upon the resistance 42. The motion of the frame is damped by spring loaded fibre brushes bearing on the motor shaft. Specification 554,595 is referred to.

Abstract: 1377713 Controlling road-traffic MESSERSCHMITT - BOLKOW - BLOHM GmbH 14 March 1972 [26 March 1971] 11785/72 Heading G4Q  To enable a smooth, continuous flow of vehicles (such as road vehicles) where two input streams thereof merge into a single output stream, suitable gaps are created, in each input stream, between the vehicles in the input stream so that, at the merging zone, gaps in one input stream are filled by vehicles in the other input stream and vice versa. As illustrated, vehicles 1, 2 in respective streams 3, 4 which merge at zone 5 into a single stream 6 are each equipped with lateral transmitters 7, rear transmitters 8 and receivers 9. Along the stream routes transmitters 10, receivers 11 and auxiliary transmitters (not shown) disposed between adjacent transmitters 10, are provided. Preferably, transmitters 7 and 10 operate in a frequency range different from that of transmitters 8. The vehicle-mounted transmitters and receiver are connected in a vehicle speed regulation circuit (Fig. 2, not shown) in an arrangement in which a speed reference value (which changes in accordance with the speed of both the transmitting vehicle and its own, receiving vehicle) is compared with a vehicle speed regulation value derived from a generator driven in accordance with the receiving vehicle speed to control the vehicle drive and brakes. Thus, in operation, the necessary spacing of the vehicles is achieved well upstream of the merging zone 5 so that a smooth transition is achieved at that zone. The speeds of vehicles in streams 3, 4 also can be regulated in accordance with speed of the flow in the merged stream 6. The system may operate using radio, light or sound (e.g. ultrasonic) waves; alternatively, a system of waveguides, into which pulses on the vehicles project, may extend beside the routes.

Filed: 1973-03-13
Abstract: 1391396 Electronic watches CASIO COMPUTER CO Ltd 13 March 1973 [15 March 1972] 12065/73 Heading G3T An electronic watch having a digital numeric display is arranged to indicate the date on demand, using the same display elements as are used to indicate the time on demand. In Fig.2, a pulse generator 19 including a quartz crystal controlled oscillator feeds timing pulses at 1 Hz to a seconds counter 20 which produces  a 1 minute carry signal every sixty pulses. The carry signals are fed to a minute counter 21 the content of which is applied to a digital display via AND gates 24, OR gates 25, a decoder 22 and a driver 18. Every sixty minutes the counter 21 sends a carry signal to an hours counter 23 the content of which is decoded at 26 and applied to the display via a driver 27. Carry signals from the hours counter 23 are fed to a binary counter 28 which produces a carry signal every 24 hours to a 31-step date counter 30 via an OR gate 29. When a date demand switch button is depressed, AND gates 31 pass the outputs of date counter 30 via the OR gates 25 to the decoder 22. At the same time the output from a NOT circuit 33 is blocked so that AND gates 24 are blocked and hence also the minutes signals from counter 21 to the decoder 22. Date indication is therefore displayed on the minute indicator (15) Fig.1 (not shown). Alternatively the date indication may be displayed on the hour indicator (14) Fig.1. The date indication may be advanced irrespective of the output from the binary counter 28, by operation of a date advancing button switch 34 which advances the count of the 31-step counter.
