Title: Improvements in Governors for Diesel Engines.
IPC: H02P23/16
Filed: 1967-05-19
Abstract: 1,185,387. Automatic speed control. ROBERT BOSCH G.m.b.H. May 19, 1967 [May 20, 1966], No.23279/67. Heading G3R. An injection pump 11 supplies a diesel engine with fuel in accordance with the position of a regulating rod 12 associated with solenoid 13, a compression spring 17 urging the rod into a position corresponding to zero delivery. The diesel engine drives a tachometer generator 10 and its speed is regulated by means of an accelerator pedal 45. When the engine is started, the output of tachometer generator 10 is insufficient to render diodes 43, 67, fully conductive, transistor 42 and diode 39 both being blocked. Transistor 65 passes a small current and diode 63 conducts so that the potential at input terminal 33 of amplifier 24 is determined by the collector potential of the transistor 65. The rod 12 is displaced towards the full-load position by the solenoid 13 until the voltage derived from potentiometer 18 balances that at the emitter of transistor 27. If the speed of the engine increases, the output of the generator 10 is sufficient to render the diode 67 fully conductive whereby the emitter-collector voltage of the transistor 65 decreases to adjust the setting of the rod 12. The rate of adjustment is determined by resistor 68, and the break-down point of diode 67 is fixed by resistor 71. If the accelerator pedal 45 is fully depressed the diode 43 becomes effective, only at very high engine speeds and when the diode is well within its conductive range, so that transistor 42 and diode 39 conduct, whereas diode 63 is blocked. The input voltage to the amplifier 24 falls at a rate set by resistor 44, the engine-speed dependent voltage being modified by adjusting the ratio of divider 47-49. At low engine-speeds, the emitter-collector voltage of transistor 84 increases so that diode 82 conducts and diode 39 is blocked. The input voltage to the amplifier 24 is now suited to idling operation of the engine. Temperature compensation for circuit 40 is provided by a negative temperature coefficient resistor 57 which has its characteristic linearized by a shunt resistor 58, and which is  associated with transistor 56 so that the output voltage of transistor 42 is stabilized within a wide range of temperature. Similarly, the negative temperature coefficient resistor 77 and shunt resistor 78 are associated with a compensating transistor 74 in the circuit 64. Partial temperature compensation is provided for the circuit 83 by the elements 86, 87, so that the slope of the idling load-speed curve is decreased with increasing temperature.

Title: Process for the retting of cocoa-nuts
IPC: D01C1/02
Filed: 1938-08-09
Abstract: 517,923. Refining cellulosic fibres. MAISANT,B. Aug. 9, 1938, No. 23444. [Class 2 (ii)] Fibres are obtained from coco anuts by a process comprising a cold treatment of the crushed or uncrushed cocoanuts in an aqueous medium having a pH value greater than 7 and a surface tension which is lower than that of pure water at the same temperature by at least 0.02 dynes per centimetre. The difference between the surface tension of the aqueous medium and that of pure water is preferably very small. The surface tension may be adjusted to the desired value by the addition of ethyl, propyl, butyl, amyl, or other alcohol to the alkaline medium. In order to facilitate removal of parenchyma and other substances from the fibres, substances may be present in the treating solution which exhibit the Brownian movement. For this purpose the solution may be prepared by adding alcohol to pure water, then adding a sulphonated vegetable oil which has previously been rendered slightly alkaline by addition of a solution of caustic soda or sodium carbonate and ammonia. The resulting solution also contains sulphates resulting from the action of the alkali on the sulphonated oil. The composition of the treating bath may be such as to prevent the growth of fungi and other organisms, but, if desired, antiseptic substances may be added to the bath. The treatment may require 24 hours or less to render the fibres free from encrusting substances.

Abstract: 1525814 Correlation evaluation THOMSONCSF 7 June 1976 [10 June 1975] 23498/76 Heading G1U The squared modulus |R(#)|2| of the correlation function R(#) of two functions A(t) and B(t), i.e., A(t) and B(t) being defined by - A(t) = exp{i# A (t)} and B(t) = exp {i# B (t)}, where # A (t) and # B (t) are the phases of two signals SA(t) = cos { 2#ft + #(t) }, and  S B (t) = cos {2#f(t-T o ) + #(t-T o )}, arising, for example, by one being the delayed echo of the other, is evaluated by detecting 7, 8, Fig. 1, the phases of the two signals, (these being denoted by # 1  and # 2 ), delaying 10 one by a time #, forming the difference 11 of the resulting signals, evaluation the sine 12, Fig. 2, and the cosine 13 of the difference signal, evaluating 14, 15 the integrals of the sine and cosine signals, and squaring 16, 17 and adding 18 the results. Thus the system evaluates the integrals - and then uses the result - The system described repeats the above process for various values of #, and then locates the peak in the function |R(#)|<SP>2</SP>, hence estimating the delay To between the original signals S A (t) and S B (t), and finally the system described determines the width of the peak to form a measure of the reliability of the estimate of To. Although the system can be implemented using either analogue or digital techniques, block diagrams using conventional digital techniques only are outlined. In this system, a single phase discriminator (503), Fig. 4 (not shown) is time shared between the two input signals (30)(40), and the results are sampled and stored over a period T. Repeated rapid read-out, with appropriate shifts, then occurs and |R(#)|<SP>2</SP> is evaluated. The peak is located by comparing and averaging the two times when |R(#)|<SP>2</SP> passes through a suitable pre-set threshold level, and the width of the peak by the time difference between the passages through the threshold level.

Title: Typewriter mechanism
IPC: B41J7/52
Filed: 1972-05-19
Abstract: 1376975 Selective printing KUROSAWA TELE-COMMUNICATIONS Ltd 19 May 1972 23654/72 Heading B6F A rotatably and vertically movable type cylinder 31 is swung for impression by a rotary electromagnet 23. The type cylinder 31 is mounted on a bracket (21, Figs. 2 and 5) pivotally mounted at (33) to frame members (29a, 29b) of a carriage (11, Fig. 1) movable along the line. Two shafts (39 and 41) provide for character selection via bevel gearing (75) and 73 for rotary movement and via gears (77, 79) and rack (69) for vertical movement of the type cylinder. The axis defined by pivots 33 passes through the point of mesh of gears (75) and 73 and gear (79) and rack (69). Energization of the rotary magnet 23 just before completion of the type character selection operation causes a locking lever 37 to rotate counterclockwise against the force of a spring 105. This results in locking levers 87 and 89 simultaneously engaging with one of the locking grooves 97 formed at the rear edge of the rack member 67 and one of the locking teeth 101 of a locking wheel 99 fixed to the shaft of the type wheel 31. The character selected is then fixed ready for impression. Further rotation of the magnet 23 then causes the bracket (21) to start its swing, whereupon the magnet 23 is de-energized. Due to inertia, the bracket continues to swing so that impression takes place. A toggle spring (109, Fig. 8) bridged between the carriage frame (29a) and the bracket (21) has its neutral point at the preselected position which is 5/6 the distance from the initial position of the type cylinder to the platen. This toggle wpring (109) always resists the occurrence of both swinging and returning actions of the bracket (21) so that both locking and release of the type wheel 31 are accomplished before the occurrence of movement of the bracket (21).

Abstract: 1421965 Interconnecting N data sending and receiving units INTERNATIONAL BUSINESS MACHINES CORP 18 May 1973 [20 June 1972] 23717/73 Heading G4A N serial digital data sending units are connected to N receiving units (N>3) via N groups each of N forcing function circuits, each sending unit being connected to a corresponding forcing function circuit in each of the groups, the forcing function circuits being connected to N, N-bit control registers such that the output of the jth forcing function circuit in the ith group, f j,i  is given by:- f j,i =d j R i,j vR i,j .R i/j+1/n  ... R i/j+n-2/n  where j = 1, ... n; i = 1 ... n; R i,j  is the jth bit in the ith control register; d j  is the output of the jth sending unit; and n is modulo n, and the outputs of each forcing function circuit group are connected to a corresponding threshold circuit arranged to transmit a binary " 1 " to a corresponding one of the receiving units when #2 of its inputs are binary " 1 ".  Four sending units are coupled to four receiving units in one of several modes determined by the contents of the control registers. In a first mode the four units are redundant and provide outputs which are threshold voted and supplied to the receiving units. If one sending unit provides a minority output certain bits in the control registers are reset to disconnect the faulty sending unit. Generally failed sending units are disconnected until the (n-2)th failure when the system switches into a comparison mode in which the outputs from the two sending units are compared, and if they are the same, are sent to all receiving units. When a mismatch occurs all sending units are disconnected. The control registers may be set for operation in the comparison mode with the sending units grouped into a number of independent redundant pairs performing independent operations. The system may also be set into the simplex mode where each sending unit is coupled to a corresponding one of the receiving units. The system may be operated in a mixed mode, e.g. with six sending and receiving units four may be connected as in the first mode above, and the remaining two as an independent redundant pair in the comparison mode.
