Title: Improvements in apparatus for spinning solutions of cellulose ethers or esters
IPC: D01D5/04
Filed: 1928-08-03
Abstract: 303,056. Ruth-Aldo Co., Inc., (Assignees of Klein, M.). Dec. 27, 1927, [Convention date]. Void [Published under Sect. 91 of the Acts]. Apparatus for making filaments.-The orifice through which the thread issues in a cell for the dry spinning of solutions of cellulose esters is situated in the bottom of the cell and preferably in a direct vertical line below the spinning nozzle, so that the thread passes directly from the spinning nozzle to the winding bobbin with as few changes in direction as possible. The thread may pass round rollers inside the spinning cell as described in Specification 283,139 and the cell may be provided with diaphragms as described in Specification 292,561. In the drawings ABCD representing the section of the spinning cell; M the spinning nozzle; E the thread; F the winding bobbin; G the thread guide and HH the delivery orifice for the thread. In Fig. 1, a typical cell is shown, whilst in Fig. 2, a cell fitted with horizontal diaphragms KL and rollers OP is shown. Roller P turns at a velocity equal to the rate of feed of the thread whilst roller O turns at a higher velocity, so that the thread is subjected to a drawing or stretching treatment. The orifices may be packed with cotton, so that, even if the thread has to describe a certain angle in relation to the vertical after passing this cotton plug before being wound on the bobbin, no acute bend is set up at that point. The orifices may further be fitted with mechanical devices to enable the sizes of the apertures to be altered at will as described in Specification 293,424.

Abstract: 205,939. Armstrong, C. C. Aug. 18, 1922. Wire and ribbon resistances, mounted on frames.-In an electric heating and cooking device wherein the metallic wire or strip forming the resistance element is wound in two spaced horizontal planes between two spaced insulating members, the arrangement of the winding is such that adjacent strands of each plane are continuous. The insulating members 3, of soapstone, asbestos or the like. are provided with grooves 5 :n their upper and lower edges, the projecting lugs 6 so formed having flanges 7 to prevent displacement of the wire 8. The members 3 are secured by screws 2 on opposite sides of a frame 1, and the resistance wires are led from a tetminal screw 10 carried by a member at one end of the frame, in a zig-zag manner between the projections on the insulating members 3, the upper and lower planes of winding being independent. On completion of the windings of the two planes the wires are passed behind one of the members 3 into longitudinal slots 12, and back to a second terminal adjacent to the terminal 10. Tn a modification, the two planes are wound from a single continuous length of wire, a vertical slot 17 being provided at the back of an insulator to enable the wire to be led down to the lower plane when the winding of the upper one is completed. The end of the frame 1 opposite the end carrying the terminals is provided with an opening throuvh which a toast rack or the like can be inserted between the heating planes, support being provided by the lower edges of channels 4 in the inner faces of the insulating members. The element may be covered, above and below, by an open grid 13 with longitudinal apertures 15 coincident with the strands of the wire.

A liquefied gas storage tank 10, Fig. 1, is built of rectangular heat insulation panels 28 lined by a liquid impervious cup-shaped member 62 resting on the base of the shell and having its sides supported against collapse by vertically spaced horizontally extending spiders 96, 98 and cables 110, 112. Vertical wooden external reinforcing ribs 16, Fig. 2, have their ends 24 engaged in upper and lower wooden rings 14 and are bolted at intermediate points to vertical planks 36, Fig. 3, which are in turn bolted at 42 to adjacent panels 28. The lining 62 comprises a bottom plate 64 of metal plastic or glass fibre and side plates 66 having overlapping edges 80, 78, Fig. 5, projecting into the storage chamber 30 over a wooden insert 83 set in the bottom panel 28. Adjacent edges 68, 70, Fig. 4, of side plates 66 similarly overlap and form expansion joints held against creep by wooden keys 74 set in the panels 28. The upper spider 96 comprises wooden inner and outer rings 100, 102 connected together by wooden radial arms 104.

The lower spiders 98 have upwardly directed radial arms connecting inner and outer rings the latter being supported by cables 112 connected to the flanged ring 86. A displaceable core 126 in the uppermost panel 28 allows for pressure relief. In a modification a base panel 218, Fig. 8, is splined to side panels 228 in which are inserted hardwood portions 248 and around which are located steel retaining bands 246.

Patent GB-501136-A (GB)
Title: Improvements in or relating to shoe bottom pressing machines
IPC: A43D25/06
Filed: 1937-08-23
Abstract: 501,136. Sole - laying presses. BRITISH UNITED SHOE MACHINERY CO., Ltd. (United Shoe Machinery Corporation) Aug. 23, 1937, No. 23020. [Class 17 (i)] Relates to multiple sole-laying presses of the kind described in Specification 408,953, wherein shoe presses are presented in turn at a loading station and fluid-pressure operated means bring about pressure between a sole-engaging pad at the loading station and a shoe positioned thereon and hold the shoe and pad pressed together until they again approach the loading station, and consists in means for automatically compensating for leakage on all the shoes under pressure each time pressure is applied between another shoe and its pad. Each press has a pipe 94 leading from the fluid pressure supply pipe for that press to a block 96, the end of the pipe being, normally, closed by a disc 114 carried by e plunger 102 having a conical end co-operating with a drair pipe 104. The head of the plunger is spaced from the disc 114 to provide an annular passage cooperating with a passage 112 leading to a pipe 116 communicating with one of the pressure pipes 492 (not shown) described in the prior Specification as under high pressure when a pad and a newly positioned shoe are pressed together. This passage is, normally, closed by a ball 98 backed by a spring which will resist the normal idle circulatory pressure described in the prior Specification. A bushing 108 engages the head 110 of the plunger 102, which is urged upwardly by a spring 106. In the position shown, the press corresponding to the block 96 is not under pressure. When a shoe has been positioned thereon and pressure fluid admitted the plunger 102 will be depressed to close the drain pipe and expose the end of the passage 112. Thereafter, each time a new press is placed under pressure, pressure fluid may pass by the ball 98 to make up any slight loss in the cylinder. When, on arriving at the operator's position, the pressure in the press is relieved, the bush 108 rises and closes the passage 112. In a modification, the pipe 94 is substituted by a pipe 118 communicating with a drain pipe 142 which may be blocked by a ball 144 normally resting on a pin 146. The pipe 118 also communicates with the underside of a diaphragm 128 depressed by a spring 130 and carrying a pin 138 normally engaging a ball 140 obturating a passage 132 leading to the pipe 492 (not shown). Pressure in the pipe 118 raises the ball 144 to close the waste pipe, and raises the diaphragm 128 to release the ball 140 to allow high pressure fluid, periodically, to make up the pressure in the cylinder during its circuit. When there is no pressure in the pipe 118 the ball 132 is held against its seat by the spring 130 to prevent escape of high pressure fluid.
