Title: Improvements in the art of signalling
IPC: H04L1/08
Filed: 1925-07-11
Abstract: 244,702. Ateliers J. Carpentier. Dec. 20, 1924, [Convention date]. Eliminating effects of disturbing currents. - As described in Specification 235,193, the effects of parasites are eliminated by repeating each message a number of times, a signal being effective only if it occurs in all the versions of the message. According to the present invention the message is received on perforated strips, and three or more strips each carrying the same message may be superposed so that a perforation which is absent from any one of the strips fails to be effective in the compound strip thus produced. If the version of the message have been - received at different speeds, they must be retransmitted locally in order that all the tapes may have the same length and spacing. In a modification of the method, the received strips are passed simultaneously through a set of transmitters whose output contacts are connnected in series, so that output current is obtained only for those perforations which occur on all the strips. For signalling by this method multiplex transmitters having rotary commutators may be employed : thus, in a six-line commutator, three lines may be used for transmitting and three for receiving. The transmitting tape may be passed simultaneously through the three transmitters so that at any moment each is engaged upon a different part of the tape.

Title: An improved process for moulding rubber articles
IPC: B29C33/02
Filed: 1921-07-01
Abstract: 186,691. Jones, F. C. July 1, 1921. Moulding rubber and hollow-ware; moulds.- Hollow rubber articles such as teats, tubing, &c., are moulded by allowing a rubber solution gelled by the Peachey or other similar process to shrink on to a core. The heated solution is poured into a mould a, the core b being previously or then inserted, and, after gelling, the core with the gel attached is removed and set aside to allow the latter to dry and contract. The mould is preferably shaped in accordance with the exterior of the required article, and so as to allow for the irregular contraction of the gel. The core b is centred in the mould a by means of a pin g inserted in an aperture c and fitting into a recess d. Removal of the moulded article is assisted by blowing water &c. through the aperture c. The mould may be formed with a contracted neck by means of a ring i sliding on the core b and having passages j, and may be constructed wholly or in part of flexible material.

Abstract: 418,503. Drilling and assembling cutlery handles. JAMES, E. H., and JAMES, J. W., 105, Trafalgar Street, Sheffield. June 18, 1934, No. 17942. [Classes 83 (iii) and 83 (iv).] A device for holding a cutlery handle while it is advanced to a drilling tool or a tang comprises adjustable jaws supported in a slide which is adapted on rearward movement to open the jaws, the latter being operated by a single actuated jaw-aligning member carried by the slide and means being provided for adjusting handles with different tapers into correct alignment with the tool or tang. The jaws 8 for holding a handle are tongue and grooved to a block 171 forming part of a slide 3 which can be moved longitudinally by a handlever 5. The jaws are connected for simultaneous movement by the head 12 of a bolt 11 connected to a yoke 14; buffer bars 15 are arranged in bosses 17 in the slide so that on backward movement of the latter the jaws are opened against compression springs 18 by the buffers, while on forward movement the springs serve to close the jaws on the handle. For positioning handles of different tapers a support 20 is provided between the jaws, this may be given various tilts by eccentrics 20<a> and 22 which are adjusted by levers 23a, 23 moving over graduated scales. The headstock for the drilling spindle may be replaced by a vice for holding knife-blades or the like when the tangs are to be forced into the drilled handles.

Abstract: 1,080,501. Piston type press filters. STAHLWERKE SUDWESTFALEN A.G. May 4, 1965 [May 5, 1964], No. 18811/65. Heading BID. The chamber of a piston type press filter is lined with filtering grids and comprises an upperportion 3, of larger cross-section than the piston 2, in which preliminary filtering takes place under the delivery pressure of the material to be filtered, and a lower portion 1, in which piston 2 is a close sliding fit and in which further filtration takes place. Figs. 1a  (not shown) and 1b represent five such presses arranged in parallel and operated by two hydraulic rams (6) via a common pressure plate (5). The filter chambers are of elongated rectangular section (Fig. 3, not shown) and their two portions 1, 3 are each lined with alternate bars (18) of rectangular and circular section, which extend vertically, engage rounded ribs (19) (Figs 4a, 4b, not shown) and whose spacing is adjustable. Behind bars (18), the walls (16) of the chambers have horizontal and vertical filtrate drainage ducts (22), (23). (24). Piston 2 and its rods 4 carry scrapers 15 to engage the walls of chamber portion 3. Scrapers 15 are of open frame shape so that sludge can pass through them down the chamber. At the lower ends chamber portions 1 are closed by a common sliding valve 10. In operation, valve 10 is initially closed and sludge delivered through a non-return valve (14) to the upper ends of the chambers, at about 10 atmospheres pressure. Once reciprocation of the pistons 2 has formed a plug 25 of solid material in each chamber portion 1, valve 10 is opened, and further working strokes cause continuous extrusion of pressed material through openings 9. Valve (14) prevents sludge returning to the supply conduit on the upward return strokes.

Abstract: 275,595. Telefunken Ges. f³r Drahtlose Telegraphie. Aug. 6, 1926, [Convention date]. Duplex signalling; wired-wireless systems.-In a high-frequency telephone system only a single carrier frequency is produced at one of the stations and is employed for speaking in both directions, and each station is provided with a selectively-connectable oscillation generator Z which serves for calling and for speaking in both directions. At the called station the carrier frequency received in the pauses of the speech is utilized for the transmitting modulator. A differential transformer B and a balancing network N, Fig. 3, may be employed to separate the modulator M and demodulator D. In a modification, Fig. 2, the separation is effected by a compensating circuit E. In the application to power lines L1, L2, chokes Sp1, Sp2 and condensers C1, C2 are pro. vided to separate the power and signalling circuits. In a further modification, Fig. 4, separate lines L1, L2 are employed for each way indicated by the arrow. The Specification as open to inspection under Sect. 91 (3) (a) comprises also a system in which a single generator is provided and is arranged at a central station, while at the sub-stations harmonics of the carrier frequency generated may be utilized for signalling. This subject-matter does not appear in the Specification as accepted.
