Title: A machine for making articles from glass tubing
IPC: C03B23/11
Filed: 1925-12-19
Abstract: 245,120. Favre, P. A. Dec. 19, 1924, [Convention date]. Making articles from tubing.-A machine particularly intended for making serum bulbs comprises means for supporting a glass tube at a number of equidistant points along its length, means for rotating the tube in front of a number of blowpipes, means for stretching the tube to draw out the heated parts, and means for severing the tube at the drawn-out parts in order to divide it into a number of bulbs. The machine, as shown in Figs. 1 and 2, comprises a number of vertical supports 7 which are free to slide on horizontal guides 8 and are connected to a lazy tongs 18, so that they can be moved to and from one another. Each support consists of two parallel plates between which a toothed ring 9 is mounted. Both the supporting-plates 7 and the rings 9 are gapped, so that a tube may be carried through the gaps and gripped by spring- operated levers 10, Fig. 3, pivoted on the interior of the rings. A tube thus gripped is coaxial with the rings and is held at a number of separated points. In operation, the rings are rotated and the parts of the tube between the rings are heated by blowpipes 50. When the tube is sufficiently heated, the lazytongs 18 is operated to separate the supports 7, thus drawing out the tube at the heated portions and leaving those portions gripped by the rings of the original diameter. The tubes to be operated on are stored in an inclined platform 29 and are fed to the rings 9 one at a time by a rotary distributor 30. Each tube is received by pivoted levers 33 which carry them into the jaws of the levers 10. After the tube is drawn out it is lifted by the levers 33 on to an inclined platform 31 down which it rolls past cutting-wheels 32 that sever it between the bulbs. Modified constructions of the devices for supporting the tubes and for feeding them to. and removing them from, the supports are also described.

Title: Weight checking and correcting apparatus
IPC: G01G15/02
Filed: 1959-09-23
Abstract: 881,183. Automatic weight control systems. FOOD MACHINERY & CHEMICAL CORPORATION. Sept. 23, 1959 [Jan. 26, 1959], No. 32368/59. Class 38 (4). [Also in Groups V, XVIII and XXXVIII] In a dough-dividing machine in which defective pieces are automatically made up to a standard weight (see Group XXXVIII) signals representing the weights of a number of successive pieces are averaged and act retroactively on the main dispensing apparatus. Averaging weight signals .-Alternating-current signals representing by their amplitude the weight deficiency (or excess) of each piece, are passed over wire 825 and capacitor 912, Fig. 28, to a detector 909 where they tend to charge capacitor 918 positively. This capacitor has just been charged negatively from a capacitor 925 on the operation of relay 890 which is energized while the piece is in the weighing position. Biasing network 913 is so adjusted that for correct weight the charge on 918 is brought to zero and for various degrees of underweight retains more or less of its negative charge. An overweight piece reverses the sign of the charge. On the relapse of 890, when the piece leaves the weighing position the capacitor discharges via an averaging network 935 in the input circuit of a valve 940. Controlling main dough dispenser.- The dispenser operates by means of pistons 42, Fig. 1, which are first forced outwardly as the dough enters the associated cylinders from a pressure chamber 41 and subsequently eject the dough pieces. The extent to which the pistons are moved outwardly is controlled by rocker arms 43 the extent of movement of which is determined by engagement of arms 46 with an abutment block 47 adjustable by a hand wheel or by a motor 51, Fig. 30. Valve 940 acts in opposition to valve 944, the input of which is manually adjustable, on a differential relay 960 which controls relays 970, 990 to cause motor 51 to run in the direction to decrease or increase the size of the pieces. These relays also charge capacitor 947 in such a direction as to nullify the signal that caused them to operate. Relay 960 then assumes its mid position, 970 or 990 falls and the motor stops. A switch 974 controlled mechanically by the dough dividing machine ensures that the motor 51 can only run when the arms 46 are not against the abutment block 47.

Title: Tecnetron in semiconductor devices
IPC: H01L29/812
Filed: 1961-09-11
Abstract: 941,629. Transistors. S. TESZNER. Sept. 11, 1961 [Sept. 15, 1960; Aug. 12, 1961], No. 32464/61. Heading H1K. A unipolar transistor comprises a generally cylindrical rod with source and drain electrodes and a waisted central section between them. The waisted section includes a first cylindrical or tapered section surrounded by an annular or frusto-conical gate electrode and a second section of reduced diameter adjacent the edge of the gate nearest the source. Such a device, comprising a rod of N-type germanium, may be formed from a conventional unipolar transistor by first electrolytically etching it in dilute soda or potash with the drain and source jointly connected to the positive side of a D.C. source and the grid to the negative side. The section of reduced diameter is then formed in the waisted section by electrolytic etching for a suitable time under intense illumination in a strong solution of boiling hydrogen peroxide using one of the circuits shown in Figs. 7 and 8. A groove is also unavoidably formed on the drain side of the gate but its depth is restricted as a result of the source-drain bias and the use of a large diameter plate electrode 32 to apply the bias to the drain. The ends of the rod are kept short so that the major contribution to the source-gate resistance is made by the resistance of the section of reduced diameter and of the gate barrier layer. With the gate reverse biased the reduced section has a high resistance but when the gate is forward biased the resistance is reduced to a low value by minority carriers injected by the gate. The device is therefore suitable for use in a flip-flop circuit. Specifications 808,734 and 853,421 are referred to.

Abstract: 1,007,223. Reciprocating pumps. Y. KUZE. Aug. 24, 1962 [Sept. 4, 1961], No. 32568/62. Heading F1A. In a swash plate pump, the angle of the swash plate 3 is varied/by means of a double acting piston 6 which is subjected to delivery pressure on either face. The piston faces are of different area and a spring 11 loads the piston 6 on the side having the smaller area. A stationary valve plate 14 is mounted eccentrically with respect to the cylinder block on a pin 13 on an oil supply manifold 12 so that the pistons discharge outside the periphery of the plate 14 (Fig. 8 not shown). The liquid is discharged through an outlet 25 and also lubricates the distributor block 21 as it rotates on the supply manifold 12. Part of the liquid discharged is led to a valve 30 from whence it is supplied to the chambers 7, 8, The rod 31 of the valve 30 may be depressed manually and pressure liquid is supplied to the chamber 34 to overcome the action of the spring 11. The swash plate then moves to the position shown in chain lines and the pump output ceases. Relief valves V 1 , V 2  prevent excessive pressure in the supply and delivery lines of the pump, and a pump p feeds liquid from a tank T into the liquid circuit. In an alternative embodiment the differential piston is in a housing located over the supply manifold 12.
