Abstract: 419,175. Cables. GENERAL CABLE CORPORATION, 420, Lexington Avenue, New York, U.S.A.-(Assignees of McKnight, E. W.; Bayonne, New Jersey, and Potter, F. M.; Rome, New York, both in U.S.A.) Jan. 4, 1934, No. 382. Convention date, May 25, 1933. [Class 36.] In a stranded electric cable having a core 32 and layers 41, 48, 55 of helically arranged strands all extending in the same general helical direction, the contact angle of lay of the strands in one layer differs from that in an adjacent layer at the contacting surfaces of the layers. The strands are individually drawn and compacted under pressure layer by layer so as to provide a smooth outer surface for each layer before the next layer is applied. Fig. 1 shows the process, the core 32 being unwound from a reel 31 and the strands of the successive layers 41, 48, 55 being unwound from reels 34, 45, 52, which are mounted on frames adapted to be rotated by pinions 36, 47, 54 on a motor-driven shaft 37 that also drives the capstan 40 that receives the finished conductor. The cable after receiving each layer of strands passes through suitably shaped rollers 42, 43, 49, 50, 56, 57, to be compressed. The rollers 42, 43, forming part of a rolling unit, Fig. 12-14 (not shown) are shaped as shown in Figs. 4 and 5 respectively, the rollers 42 compressing the strands vertically and the rollers 43 compressing them horizontally so as to remove the small ridge formed by the first compression. The rollers 49, 50 act similarly. The rollers 56 are similar to the rollers 42 excepting that the final shape they produce is slightly oval, and the rolling unit 57 (Figs. 15 and 16, not shown) comprises two sets of rollers, (Figs. 9 and 10 not shown) the first rolling the cable horizontally to a slightly oval shape in a perpendicular direction and the second set rolling the cable vertically to produce a final round shape.

Title: Improvements in automatic air vents for hydraulic pipe lines under pressure
IPC: F16K17/19
Filed: 1933-01-06
Abstract: 402,947. Vents for hydraulic pipe lines. GIOVENALE, B., 39, Lungotevere Mellini, Rome. Jan. 6, 1933, No. 454. [Class 69 (ii).] Hydraulic pipe lines are provided with vents allowing inlet and escape of air during filling and emptying of the line ; some forms also allow escape of air during normal working. In the form shown in Figs. 2 and 3, the fitting comprises a chamber 2 connected to the line through a slide valve, a piston 7 carrying a valve 8, a float chamber 29, and a small cylinder 42 in which is a piston 16 carrying a valve 13. A pipe 18 connects the upper ends of the float chamber and cylinder 42, a pipe 26 connected to the pipe line leads to chambers 4, 6 under the control of valves 23, 24, and the chambers 2, 4 are connected by a pipe 3. When the pipe line is being filled, air only is first expelled at 5; when water only begins to escape, the valve 8 is raised owing to the pressure in the chamber 6 exceeding that in the chamber 4. During emptying of the line, the valve 8 opens. During normal operation, air arriving at the fitting collects in the container 29 expelling water therefrom, the float 30 sinks, and air under pressure passes through a valve opening 35 and through the pipe 18 to cause the piston 16 to open the valve 13, so that air escapes via 2, 3, 4, 11 and 20. In order to operate the movable parts when desired to prevent sticking, valves 23, 24, 25 are actuated by a member 28, the down stroke causing the valve 8 to open and the upstroke causing it to close ; opening and closing of a valve 38 causes the opening and closing of the valve 13. Where the operation of the device is to be limited to venting only during the filling and emptying of the pipe line, the float chamber 29 and the cylinder 42 are dispensed with. In another form for venting under all conditions, the float chamber 29 and cylinder 42 are connected to each other and the pipe line by a T-fitting as shown in Fig. 4, and a non-return valve 43 and spring 44 are provided.

Abstract: 1460791 Continuous casting MITSUBISHI RAYON CO Ltd 7 Jan 1974 [18 Jan 1973 (2)] 608/74 Heading B5A [Also in Division C3] In a process for continuously casting a sheet of methyl methacrylate polymer (see Division C3) in the space formed by a pair of co-operating endless belts 1 and by continuous sealing gaskets 7 running with and held between the belts 1, the material between the belts is heated to 160 C. to 120 C. during the final stage of polymerization and is cooled at a rate of not more than 20/minute and preferably not less than 0À5/ minute from 120 C. to 105 C. to improve the heat distortion temperature of the sheet. A metering pump 5 is connected to a device 6 which feeds a monomeric or prepolymerized liquid between steel belts 1 which are supported by groups of rollers 4 where hot water from sprays 8 is directed on to the backs of the belts. The water is cleaned from the belts before they enter the final polymerization zone where they are heated by infra-red heaters 9 or hot air jets. Cooling is by cold air blown through ducts 10 and 11. The belt tension is adjusted by rams 15 or springs acting on belt pulleys 2. The angles of the belt pulleys and rollers may be adjusted to counteract snaking of the belts. The water on the backs of the belts is trapped by a sponge roller 31 (Fig. 3, not shown), and drips off or runs under the edges of the belts. Water between the edges is then removed by a stationary sponge 36 (Fig. 5, not shown), or a rotatable sponge ring 37 from which water is squeezed by rollers 39, Fig. 6b. Alternatively water is sucked off through nozzles 40, Fig. 7b, or blown off by hot air directed upstream through similar nozzles 41 (Fig. 8, not shown).

Title: Apparatus for a signalling-and indicating installation
IPC: G08B5/36
Filed: 1972-01-07
Abstract: 1345080 Selective signalling S G ANDERSSON 7 Jan 1972 [11 Jan 1971] 809/72 Heading G4H An apparatus for use at a station of a signalling and indicating installation, comprises a transmitter having a key controlling coding means to simultaneously generate a control signal and at least two address signals, and a receiver having decoding means controlling a lamp via storage. In a hotel, such apparatus is provided with respect to each hotel room, at a desk clerk (or room attendant) location, at a cashier location and at a maid supervision location. When a key is closed at a transmitter, a pulse is applied via a differentiating element, an amplifier, and diodes, to a predetermined two (respective to the associated hotel room) of a set of address wires, and to a predetermined one of two control wires. The address and control wires, and two power supply wires are common to all the apparatuses. At a receiver, the state of a lamp is controlled by a flip-flop which is set when pulses arrive on the respective two address wires and on a predetermined one of the control wires, and is reset when pulses arrive on the two address wires and the other of the control wires. Using this system, the desk clerk can light the lamp corresponding to a given hotel room at all three locations, and the cashier can extinguish it. Bistable relays may replace the flip-flops. Two extra power supply lines for the lamps, one carrying clock pulses to give intermittent energisation, may be provided, together with an extra control wire. In this modification, both positions of some keys can produce output to the wires via respective differentiators, &c., and lamps associated with other keys use two bistable relays, controlling continuous and flashing energisation respectively. In this case, the cashier's action changes the maids' supervisors' lamp from continuously on to flashing and she can extinguish it when the room is ready to be reoccupied.
