Abstract: 711,481. Kinematograph apparatus. ESSOLDO CIRCUIT (CONTROL), Ltd. Dec. 28, 1951 [Jan. 26, 1951], No. 2108/51. Class 97(1) [Also in Group XXXVII] Kinema programme producing means are controlled by means adapted to generate controlling electrical impulses and/or to effect displacements of mechanical controlling members automatically in a predeterminable sequence under the control of an impulse generated from a running kinematograph film and/or by means energized by a preceding one of said impulses. The form shown comprises a drum 1 rotated intermittently by a pawl 8.engaging a ratchet 7 and actuated by a solenoid DP. A manually operated lever 13 disengages the pawl from the ratchet for initial manual setting of the drum using the scale 11. Holes are provided in the drum in annular rows 2a, 2b ... 2m each aligned with a pair of contacts 4. Pins inserted in the holes project from the drum and each pin holds one of the pairs of contacts closed in one of the successive drum positions determined by the pawl and ratchet. The holes in which pins are placed are chosen in accordance with the control functions required. Rotation of the drum may be started, at the end of a film, by an impulse derived from change-over apparatus as described in Specification 711,480. The drum may then control the interval programme, including opening and closing proscenium curtains, starting a projector for "trailers" or advertisements and restarting the automatic change-over apparatus. If part of the programme is required to be of variable length the drum may start a timer set as required to produce the next movement of the drum. The drum may also be moved by completion of a circuit by actuation of any mechanism started by contacts on the drum. Closure of drum contacts may also move the drum itself in order, for example, to continue the drum rotation to the initial position when the interval programme is completed.

Title: Decimal addition
Inventor: SCHMOOKLER MARTIN STANLEY
IPC: G06F7/494
Filed: 1971-01-18
Abstract: 1,270,909. Binary coded decimal addition. INTERNATIONAL BUSINESS MACHINES CORP. 18 Jan., 1971 [13 Feb., 1970], No. 2320/71. Heading G4A. A BCD adder for adding n digit operands has logic circuitry for adding each pair of decimal digits which receives C in , the carry in to that pair, and generates Cd, the carry cut to that pair. The parallel logic circuitry can generate Pi (the OR function of the i bit of each digit where i=1, 2, 4, or 8) and Gi (the AND function of the i bit). It can be proved that C 1 =G 1 + P 1 C in , K=G 8 +P 5 P 4 +P 8 P 2 +G 4 P 2 , and L= P 8 +G 4 +P 4 G 2 , and hence that the carry out Cd = K + LC 1 . Using these formula it is possible to generate the carry for each pair of decimal digits without generating the binary carries of each bit. Theory.-When two BCD digits A, B are added a carry should be produced when the sum is ten or more or when the sum is 9 and there is a carry from the previous stage. Where A, B is logical AND of A and B and A+B is logical OR for A and B, the carry Cd=A 8 B 5 +A 5 B 4 + A 8 B 2 +B 8 A 2 +A 8 A 1 B 1  &c. (i.e. all possible combinations equalling 10 or more) [A 8 A 1 +A 8 B 1 + B 8 B 1  &c....]Cd-1 (i.e. all possible combinations equalling 9 plus I for a carry). The above formula can be derived from this. The circuitry.-Figs. 1 to 3 (not shown), show a 2 digit, four logic level, adder in which the decimal sums of the higher and lower order digits are added separately. Figs. 4-6 (not shown), are similar but use three logic levels and Figs. 7 to 12 (not shown) show a six digit, eight logic level adder using carry look ahead.

Abstract: 269,980. Hopkinson, F., and Henshilwood, A. B. Jan. 28, 1026. Yarns and threads; processes.-In the preparation of uniform or even textile woven and knitted fabrics of extreme thinness and lightness, a sliver of animal fibre, such as botanv or cross-bred wool, or mohair, alpaca, or the like, and one or more slivers of artificial silk or other vegetable substance, the fibres or filaments of which are approximately of the same length as that of the animal fibre used, are taken together through all the subsequent processes of preparing. combing, gilling &c. to produce a thread. The. actual mixing or combining may be effected at any stage of the process before combing or subsequently, and a roving of animal fibre may be combined with one or more rovings of vegetable fibre and two drawn out simultaneously prior to twisting. The slivers may be combined in any proportion By using the different fibres of the same length or staple, a uniform fine thread is obtained by drawing out. This thread is woven or knitted into a fabric which is subjected to a process by which the vegetable matter is taken away, leaving a very fine even fabric of animal fibre. A fabric having softness of handling, cover, and maximum lustre may be produced by the known process in which the compound thread obtained as described is twisted with an extra vegetable thread having opposite twist, so that in the final product the compound thread becomes untwisted to any pre-arranged extent.

Abstract: 1459394 Automatic feed weigher B D H CHEMICALS Ltd 18 Jan 1974 [19 Jan 1973 6 March 1973] 2831/73 and 10727/73 Heading G1W A dispensing apparatus comprises a weighing unit having a platform adapted to receive a container to be charged with a substance and a loadcell connected to the platform arranged to produce signals dependent on the weight on the platform; an electronic control unit arranged to receive the signals produced by the load-cell and operable in response to such signals first to sense the tare weight of a container on the platform and then, subsequently, to measure the weight of the charge supplied to the container; and a dispensing unit automatically operable in response to command signals provided by the electronic control unit to open when the tare weight of the container has been zeroed and then to close when a predetermined weight of subtance has been dispensed into the container. The required weight is set by selecting a resistor from a bank of resistors and then setting a potentiometer to give a particular voltage on one input of a comparator and the signal from the load-cell is applied to the second input of the comparator so that equality is provided by a zero signal out of the comparator which operates a relay to close the pneumatically operated filling valve. The valve is closed in two stages under the control of separate comparators to give a final dribble feed stage to give high accuracy of cut-off. In operation an empty container is placed on weighing platform 5 and button 11 pressed to zero this weight and start the filling cycle. When the weight signal is zeroed by means of a motor driven potentiometer in control unit 4 an opening signal is applied to valve 3 and the container is filled. When the correct weight is reached the valve is shut off. The weights can be monitored on digital display 10 so that manual control can be selected to be used by operation of a changeover switch. A printer can be attached to the control unit 4 so that a record of the weights is obtained. The dispensing head can be moved both vertically and laterally by handles 47, 48 and may be provided with a retractable spout which is interlocked with the control system so that filling can only occur with the spout down. For dispensing flowable solid materials a screw conveyor can be used and it is stated that the dispenser can be used for blending materials.
