Abstract: 1,239,532. Ketonitriles. DYNAMIT NOBEL A.G. 3 Feb., 1970 [4 Feb., 1969], No. 5212/70. Heading C2C. [Also in Division A5] Novel ketonitriles having the general formula wherein R 1  and R 2  are each C 1 -C 4  alkyl groups, R 3  and R 4  are each hydrogen or C 1 -C 4  alkyl groups or together form a cyclic ring, and n is 0, 1 or 2, are prepared by condensing a diol of the formula (II) with a cyanaldehyde of the formula in the presence of an acidic catalyst. The condensation is preferably carried in an inert solvent which is capable of acting as an entraining agent to remove any water formed during the reaction. The diol may be obtained by condensation of formaldehyde with an aliphatic ketone which latter also contains a methylene group, in the presence of an alkaline catalyst. The ketonitriles, in admixture with an inert carrier, may be used as herbicides.

Abstract: 1,251,634. Transistor bi-stable circuits. INTERNATIONAL STANDARD ELECTRIC CORP. 7 Jan., 1970 [14 Jan., 1969], No. 827/70. Heading H3T. [Also in Divisions G4-G6] Digital data is shifted from one register to another through serially connectible diodes. A register, for example register A, comprises integrated circuit bi-stable cells AFF1, AFF2 each bi-stable state of which can exist in three states: normal, receive or transmit (Figs. 2A to 2C, not shown). The normal, receive and transmit states are effected by biasing the emitter to 0, + 1 V., or - 1 V. respectively and the bistables are two conventional cross-coupled transistors. To transmit a binary digit from a cell in one register to a cell in one or more other registers, a computer causes the appropriate switches " A Reg SW, B Reg SW &c." to simultaneously put the appropriate cells into the transmit or receive states, the resulting voltage overcoming the bias of the diodes to transfer the digit. Data can be transmitted in parallel to a register which can then return it to the original register skewed as many digits to the right or left as desired, thus replacing a shift register. It can also be used for complementing a word.

Abstract: 1,264,617. Automatic tuning arrangements. PLESSEY CO. Ltd. 15 May, 1969 [15 May, 1968], No. 23188/68. Heading H3Q. In an automatic tuning arrangement the bandwidth of a tuned filter circuit is first measured by tuning over the pass band in a first direction, and the tuning point is then returned to a predetermined proportion of the bandwidth. A filter is tuned by a motor coupled to a gear-box driving tuning means, the motor shaft having attached to it a disc having apertures which allow light to fall on a photo-cell. Pulses are thereby generated during tuning, which are applied to an AND gate: when the signal voltage at the output of the filter reaches a predetermined threshold level T, at tuning point Y 1 , this gate is opened, allowing pulses to reach a counter. Counting is terminated by closure of the AND gate when the second tuning point Y2 is reached, at which the voltage at the output of the filter falls below the threshold level T. The direction of tuning subsequently reverses, counting recommencing when the point Y 2  is reached: it is arranged that a frequency doubler precedes the counter when tuning in this direction, so that a count equal to the original count is reached when the tuning is exactly at the centre of the filter passband. The tuning is then caused to stop. As an alternative to the frequency doubler, a frequency halving circuit may be connected before the counter during the forward tuning. By using a frequency multiplying or dividing circuit of different factor, the tuning may be stopped at a different point in the filter -pass band. The arrangement may be used for tuning the input circuits of a superheterodyne receiver, in which the oscillator frequency is set e.g. by a digital frequency generator; there is injected into the aerial circuit during tuning a frequency equal to the sum or difference, as the case may be, of the local oscillator and intermediate frequencies.

Abstract: 1,267,219. Toy. DART INDUSTRIES Inc. 8 Aug., 1969 [12 Aug., 1968], No. 39912/69. Heading A6S. [Also in Division G5] A toy comprises a hollow body having curved surface portions and a plurality of planar surface portions which are adjacent one another on the body, and formed with openings of differing geometrical shapes communicating with the interior of the hollow body, and which are capable of maintaining the toy in stable resting positions on any flat surface. The toy provides for the introduction of individual block members (through the openings in the planar surfaces) and storage therein, and comprises means to gain access to the interior of the hollow body for removing the blocks. In one embodiment, the toy comprises a hollow sphere 10 bearing flat surfaces 23 (Fig. 28) in which are openings of shapes corresponding to blocks 45, 50, 53, 55 which may thus be inserted into the sphere. The openings have upstanding and flared rims to aid alignment of the block with the opening. The sphere is formed of separable halves 11, 12 (Fig. 4) held together by a tensioned spring, e.g. shock cord 27, which is located inside interfitting tubes between handles 28 located in recesses 36. The cord is so fixed in hook members attached to the handles that rotation of the handles enables its tension to be so adjusted that the tubes are still in loose engagement when the hemispheres are pulled apart to the fullest extent of the cord, thus ensuring ease of re-engagement when tension is released. In another embodiment, the sphere is in one piece but is provided with a detachable lid to enable it to be emptied of blocks.

Abstract: 1297083 Orientating sweets KOMBINAT NAGEMA VEB 23 June 1970 30413/70 Heading B8S Sweets 15, initially in random orientation and to be sorted into equal spacing in single file, are fed by a vibrating shoot 16 to a rotating table 1. The latter is surrounded by a fixed wall 2, the periphery of the upper edge of which varies in height uniformly from a minimum (L.H., Fig. 1), to a maximum (R.H., Fig. 1). The wall 2 is surrounded by a resilient ring 3 which is guided to follow the periphery of the wall 2 by the action of a circumferentially-positioned series of rollers 5 each having grooves 4. The latter engage an outer beading formed on the ring 3 which is given a rotary movement by two of the rollers 5 being driven. Above the ring 3 is a further fixed wall 7 having a radius greater than the outer periphery of the ring 3 by an amount equal to the width of a sweet 15. The latter are carried round by the table 1, and are brought by friction and centrifugal force against the wall 2 in to the position shown in Fig. 5, moving towards the low part of the wall. Any which are orientated with their longitudinal axis vertically disposed are displaced by a deflector member 18. The sweets then pass on to the upper annular surface of the ring 3, and any that are radially aligned are knocked back on to the table 1 by a deflecting member 91. They then pass under a resilient plate 23 (Figs. 3 and 4), and as they come out from beneath the latter, they are engaged by pushers formed by bristles carried in moving holders on a chain 12 passing around sprockets 13, 13<SP>1</SP>. These are shown in Fig. 3, but are shown only by dot-dash lines in Figs. 4 and 5. The bristles may be augmented by the action of opposed endless belts 22, 22. The sweets 15 are thus fed into engagement with recesses 11 of an outer ring 10. The latter takes them round until they are removed from the recesses by opposed endless belts 20. Any sweets on the ring 10 which do not engage in the recesses 10, are swept back to the plate 1 by a brush roller 25. A scanning device 17 controls the feed of the shoot 16.

Abstract: 1339724 Balancing wheels GKN TRANSMISSIONS Ltd 19 Jan 1971 [27 Jan 1970] 3867/70 Heading G4H [Also in Division G1] Wheel balancing apparatus comprises a shaft 10 on which a wheel is rotatably mounted, a pair of bearings A, B, piezo electric transducers 19 for measuring the reaction forces due to wheel imbalance at each bearing and counters 36-39 which indicate to an operator the values and positions of counterbalance weights to be added to the wheel in a pair of spaced planes defined by the rims of the wheel. The wheel is positioned on the shaft such that the bearing A lies in the plane of the inner rim. The transducers produce sinusoidal voltages, the amplitudes of which depend on the magnitude of the out of balance weight and the phase angles of which depend on the position of the out of balance weight. These voltages are fed to a computing circuit 42 which contains potentiometers set according to measurements of the radius and width of the wheel rim. The circuit 42 generates sinusoidal voltages the moduli of which represent the weight to be added to each rim and the phase angles of which represent the positions of the weights. These voltages are fed to zero detector circuits 47, 48 which hold gates 41 open to enable each counter 36, 38 to count clock pulses generated by a magnetic transducer 26 which co-operates with a toothed ferromagnetic disc attached to the shaft 10. Each clock pulse represents five degrees of rotation from a datum position and the gates 41 are closed when the circuits 47, 48 detect the zero cross over point of their input voltages. The counters 36, 38 therefore display the positions of the weights to be added to the inner and outer wheel rims. The voltages generated by the circuit 42 are also fed via rectifiers 54 to comparators 51 which receive a second input from a ramp generator 49 supplied by the clock pulses. Gates 41 connected to the counters 37, 39 are opened when the ramp voltage exceeds that determined by potentiometers 53 and are closed when the ramp voltage exceeds the output of the rectifiers 54. During the time that the gates 41 are open, clock pulses are counted by the counters 37, 39 which display the magnitude of the weights to be added to each rim. Reset pulses, generated by a transducer 27 are fed to the counters via gates 40 these gates being closed by a signal generated by a speed detector 60, time delay 61 and memory 62 when ten measurements have been made by the counters, the measurements being made once every ten revolutions of the wheel. The signal from the memory 62 also stops the motor rotating the wheel.
