Abstract: 459,502. Showerbaths. JUNKERS & CO., G E S., 35, Junkerstrasse, Dessau, Anhalt, Germany. Oct. 12, 1936, No. 37646. Convention date, Nov. 27, 1935. [Class 26] A shower-bath device has a flexible pipe 17 slidably passing through a fixed guide so as to permit the device to be vertically adjusted and retained at any convenient level. The guide may be constituted by a curved tube 19 both ends of which are directed downwardly and is secured to a wall or to a waterheating apparatus 10, which supplies the device through a pipe 11, under control of a valve 16 which may also direct the supply to a bath through the pipe 14. The device is retained at the desired level by the friction between the contiguous surfaces of the pipes 17, 19, or by the provision of devices such as springs or screws within the pipe 19. One end of the pipe 19 may be shaped or provided with means such as springs to receive and retain the handle 21 of the nozzle and a stop 22 serves to limit the extent to which the nozzle may be lowered.

Abstract: 474,180. Gas-blast switches. STRAUSS, (nÚe RUPPEL), F. Oct. 15, 1936, No. 28090. Convention date, Oct. 15, 1935. [Class 38 (v)] In a multipole pressure gas switch in which each pole has a power switch 1, 2, actuated by gas under pressure admitted by a pipe 10 to a chamber 11, in series with an isolating switch 15, the isolating switches being coupled so as to operate together, the isolating switch of each pole in the closed position retains the associated power switch closed, so that when the isolating switches open, simultaneous opening of the power switches is obtained without coupling them together. In one arrangement, Fig. 1, when the arm 15 of the isolating switch moves away from the cooperating fixed contact 20, a lever 16 is moved aside by a spring 17, thereby releasing a rod 8 connected to the movable contact 2 of the power switch. During the first part of its movement, the arm 15 moves along the wall 21, which has the same potential as the contacts 20 and 2, and a short arc is formed between the arm and the wall. The arm 15 only leaves the wall after the arc between the contacts 1 and 2 has been extinguished. In a modification, Fig. 2, the fixed contact 20 of the isolating switch is directly mounted on the rod 8, and the latter is thereby prevented from moving until the arm 15 starts to move. The arm 15 does not leave. the contact 20 until the arc has been extinguished at the contacts 1, 2.

A manifold 17 co-operates with guide-plates 18, 19, with a support block 22, and with rollers 24, 23 to direct the edges of the web upwardly and to form the. web into a U-shaped chamber 83 enclosing the products as shown in Fig. 3. As the web passes through the machine, the upturned edges are brought close together by guides 32, 22, are heated by heating bars 36, 37, and then pass through sealing rollers 39, 40. The manifold may include means for supplying inert gas to the chamber 83 during the wrapping process. In a second embodiment, Figs. 8 to 15 (not shown), the web is folded over so that the two edges face one another and are displaced one above the other, the edge portions being brought into overlying relationship and then sealed. Web guidance.-Edge sensors 46, 47 sense the position of the upturned edges of the web and control pivoted tracking rollers 59, 72 which urge the edges into a matched condition, whereby the web always maintains a given relationship with the manifold 17, guides 32, 33, and heating bars 36, 37.

Abstract: 616,948. Hydraulic machines. DUNNING, L. T. Sept. 25, 1946, No. 28606. [Class 69 (ii)] [Also in Group XXVI] In a hydraulic valve gear, for fluid pressure engines (see Group XXVI), the valves are operated by ram and cylinder units. Each unit comprises a fixed ram 92 having a chamber 95 adapted to receive liquid under pressure, a reciprocating cylinder 94 engaging the stem of the valve and a main valve 96 having mounted therein a pilot valve 97. When the engine valve is closed, valves 96 and 97 are open such that liquid under pressure admitted to the chamber 95 passes through the pilot valve 97, provided with a grooved stem 109 and moves the cylinder 94 upwards, thereby allowing both valves to move upwards, under the action of their retaining springs 112 and 113, such that a collar 103 on the end of the main valve 96 is moved clear of a counterbore 99, within the ram 92, to allow the liquid to pass through a longitudinal grooved passage 98 thereby increasing the speed of the cylinder 94 until the head 102 of the valve 96 engages its seat 101, after which liquid flows only through the pilot valve 97, thereby damping the speed of the cylinder 94 until the head 105 of the valve 97 engages its seat 106. A similar operation takes place when the liquid is exhausted during the closing of the engine valve under spring pressure.
