Television. - In television-transmitting apparatus of the kind in which scanning is effected by illuminating the object with a moving spot of light, the light reflected from the object 6<1> or 6<11> is concentrated on to the light-sensitive cells 4 by means of reflectors 8; the object 6 can thus move towards or away from the cells (e.g. into the positions 6<1>, 6", Fig. 2) without unduly altering the proportion of light falling on the latter. The reflectors 8 may be mirrors or whitened surfaces; they may form a closed tubular or box-like structure, or one or two reflecting screens may be arranged at the sides of or above or below the axis of the system. As shown in Fig. 3, the reflectors may have non-reflecting portions 12 so shaped as to bring about more complete reflection when the object is distant from the cells 4, as at 6<1>, than when it is close, as at 6<11>. According to the second Provisonal Specification the reproduced image may be made very small, for the purpose of minimizing the inertia of the moving parts or of economizing space, and may be viewed through a microscope.

Filed: 1952-03-04
Abstract: 722,436. Filling ampoules. SICKEL, H. March 4, 1952. No. 5694/52. Class 81 (1). A method of processing ampoules comprises a continuous correlated series of operations comprising at least needle-filling and sealing, the ampoules being conveyed, singly or in groups, with uniformly adjusted necks, in such a manner that they are presented directly to each treating means in turn in accurate operative relationship. The uniform adjustment of the necks involves accurate positioning and orientation of the ampoule bodies which need not involve a support for the necks when operations, other than on the necks themselves, are being carried out. As shown (Figs. 1 and 2) a carrier holds a plurality of ampoules by means of V-shape grooved bars 3 and 4, end bars 2 and clamping bar 9 and is conveyed along a definite path by means of key-way 13 and guide rails (Fig. 4) and rotary transferring members F, J and M (Fig. 8). The treatments may include loading (A. B and C), neck cutting (between D and E), knocking off neck tips (F), cleaning, of inside of ampoules (G), drying and sterilising empty ampoules (H), prefilling with inert gas (K), final filling (L), sealing by fusion. (between N and O), marking (between P and Q) burning in of markings (R) and finally ejection (S). In another modification Figs. 11 and 12, (not shown) the ampoules are treated two at a time on a stationary frame having supports with V-shaped grooves, the supports being either rigid or rotatable about a horizontal axis depending on the treatment to be effected, and the ampoules are lifted from one support to the next by means of forwarding mechanism similar to the supports. The treatments include neck cutting, gas prefilling, sealing and marking. In another modification. Fig. 13, (not shown) a rotary body, with horizontal axis, is provided with treating stations spaced around it at suitable positions, i.e. means for knocking off the ampoule neckends and means for cleaning and sterilising on the downward circuit and means for drying, cooling-down, gas-prefilling and filling on the upward circuit. A modified form of carrier Figs. 14 and 15, (not shown) comprises a circular disc at the centre of which the ampoule is clamped, which is employed in conjunction with a suitable track. for example a track having U- or L-section rails.

Abstract: 1479404 Vector processing CONTROL DATA CORP 11 Feb 1975 [13 March 1974 17 May 1974] 5763/75 Heading G4A Individual streams of operands A 1 -A n  and B 1 -B m  forming a respective operand vectors A, B are passed through a buffer system in order to align the operands of one stream with correspondingly positioned operands in the other stream. The operands are supplied from a memory which is divided into banks a plurality of which may be accessed simultaneously, and misalignment of operand pairs arises, in part, because, once accessed, a bank cannot be accessed again for a given period (called a major cycle). When any bank is shared by two vectors or two banks share the same addressing circuits an accessing conflict may result. The first accessed operands of a vector, e.g. vector A, are temporarily stored in buffer registers 28, 26 and 17, Fig. 2, which are filled in that order, and then, if necessary in a buffer store 38 until the first accessed operand of the other vector B appears at the output of the corresponding buffer register 33. Thereafter, pairs of operands are read out of the buffer registers 28, 33 with new operands passing straight to buffer registers 31, 33 in the case of the vector B and via buffer register 17 or buffer store 38 to buffer registers 26, in the case of vector A. Resultants forming a resultant vector and derived by an arithmetic operation performed on operand pairs A 1 B 1 , A 2 B 2  and so on are buffered at 61 until the required memory bank(s) is(are) free (line 54). A counter 62 signals control 44 to store operands and thus halt the generation of further resultants when a given number of resultants have been stored in buffer 61. In order to save storage space, only non-zero and finite operands may be stored, and in this case, each such sparse operand vector has an associated order vector the 1 and 0 bits of which indicate the presence and absence of correspondingly ordered operands in the memory. The order vectors X, Y for two operand vectors A, B are read from memory to corresponding buffer registers 112, 115, Fig. 5, and thereafter are examined bit by bit in channels 116-120 and 121-125 to enable an output from operand registers 104, 109 only when the current order vector bit is a 1. Additional logic 126-128 causes shifting of the partial order vectors (up to 16 bits) in registers 117, 122 to skip positions in which both order vectors have 0 bits. Circuits are also described for generating the order vector Z for a resultant vector and for controlling the storage of resultants to derive a sparse resultant vector.

The Specification describes a similar lever arrangement to that on the bicycle which is the subject of Specification 907,467. It also describes an additional embodiment as in Fig. 4 which omits the V-shaped member 4 which in Fig. 1 (and Fig. 2, not shown) constitutes an additional pair of trailing arms extending above the arms 40 to the wheel spindle plates 24 having plate members 41 bridged by tubes 43 and 44, the latter of which is secured by a strap 30 to the face plate 26 of a rubber spring 6 bonded on to the frame 1. The pivot 5 lies in the line joining the wheel axle 2 and the pedal crank axle. In Fig. 2 (not shown) a calliper rim brake is mounted on the tube 43 above the lever instead of below as in Fig. 1. Because the transmission 8 does not have to pass between the saddle-forks a cog-belt may be employed instead of a chain.

Abstract: 1,085,574. Measuring tension electrically. S. HEIM. Feb.10, 1965 [Feb. 25, 1964], No. 5875/65. Heading G1N. [Also in Division G3] The tension of a moving yarn or tape is measured by periodically deflecting the yarn by a predetermined distance from a straight path and measuring the force required to cause this deflection. In one embodiment, the yarn 17 passes fixed guide pins 18 between which it is contacted by a ceramic member 16 mounted on a Piezoelectric crystal. The crystal is itself mounted at one end to a cantilever arm (shown in end section at 14) the support 13 of which is oscillated at e.g. 50 or 60 c.p. s. by a diaphragm 11 driven by an A. C. energized moving coil and magnet system, Fig. 1 (not shown). The output from the Piezo-electric crystal is an alternating voltage, the peak value of which is determined by the tension in the yarn. The signal also contains a noise component which may be eliminated by damping the crystal or by electrical filters. In modifications, the guide pins may be oscillated instead of the crystal, the oscillatory movement may be obtained by Piezo-electric, magnetostrictive, or electro-static transducers, and the Piezo-electric crystal may be replaced by an electromagnetic force transducer. The output from the measuring device may be compared with a reference signal to control yarn tension, a break in the yarn can also be detected to shut down a machine.
