Abstract: 766,200. Printing -telegraph systems. ATELIERS DE CONSTRUCTIONS ELECTRIQUES DE CHARLEROI. Feb. 1, 1955 [Feb. 2, 1954], No. 2937/55. Class 40 (3). In a teleprinter system using radio transmission, signals represented in the five-unit code on a perforated tape are transmitted in a two-unit code comprising two successive pulses of alternating current of different frequencies, and at the receiving station are reconstituted by a two-unit receiver into a five-unit code selectively operating five members to perforate a tape or control a printer. The two unit signals are derived by employing eight different frequencies to represent the possible code combinations of the first three units of the five unit signal and four different frequencies to represent the combinations of the fourth and fifth elements, the signal transmitted being constituted by one of eight different frequencies followed by one of four distinct frequencies. Transmitting - arrangements. The selective closing of contacts Kl, K2, K3 by feelers associated with the first three elements of the signal correspondingly operate relays R1, R2, R3 having tongues engaging two, four and eight contacts so that a circuit is completed to one of the generators G1 ... G8. Similarly, the selective operation of contacts K4, K5 in respect of the perforations for the fourth and fifth elements correspondingly operate relays R4, R5 having tongues associated with two and four contacts so that the two final elements effect connection to one of the generators G9 ... G12 providing four different frequencies. Contacts z1, z2 in the circuits of the relays R1, R2, R3 and R4, R5 respectively are closed in succession by the transmitting apparatus. Receiving-arrangements. The reception of a frequency f1 ... f7 closing a contact k1 ... k7 applies a positive potential to the grid of one or more thyratrons T1 ... T3 normally having a negative grid bias. The thyratrons rendered conducting operate associated electromagnets E controlling punch or selector members. The operation of one or more of the thyratrons T1 ... T3 or the reception of frequency f8 closing contact k8 and operating valve T6 energizes a relay R which at contact r applies a positive potential to the anodes of the thyratrons T4, T5, T7. The operation of one or both of the valves T4, T5 by a frequency f9, f10 or f11 energizes the associated magnets E to operate the corresponding punching or selector members. The operation of one of the valves T4, T5 of the valve T7 by the frequency f12 operates a relay R0 which couples apparatus to effect the punching of a tape or the selection and printing of a character. The frequencies f8, f12 represent the spacing or non-operative elements of the 3-unit and 2-unit groups of the five unit spacing signal. The apparatus set into operation by the relay R0 also opens and recloses the anode circuits of the thyratrons T1 ... T3 and T6 so that relay R releases and at contact r cuts off the anode voltage of the thyratrons T4, T5 and T7.

Title: Improvements in emulsions for surfacing roads
IPC: C08L95/00
Filed: 1933-01-31
Abstract: Bituminous emulsions for surfacing roads consist of a mixture of about 50 per cent of bitumen, e.g. natural bitumen or petroleum distillation residues, and of about 50 per cent of tars obtained during the manufacture of lighting gas in ovens with continuous charging, e.g. in ovens of the Glover-West or Woodall-Duckham type, and of either 3 per cent of Swedish residuary oil or from 2 to 5 per cent of middle phenolic oil, which is then emulsified with water containing soap, casein or other suitable emulsifying agent.  The tars obtained by the distillation of coal are evolved at a temperature of 400-450 DEG  C. and do not contact with surfaces heated above 600 DEG  C. for any appreciable period of time.  The emulsification may be carried out in a slow mixer or in a disintegrating mill such as a centrifugal turbine constituted by two rotating discs about \ba1/10\bemm. apart, the mixture being introduced at the centre and the emulsion discharged at the periphery.  For a surface of thickness about 5-6 cm., an emulsion containing water only up to 12-25 per cent of the total weight may be used, and is laid hot at a temperature of 45-80 DEG  C.  The low temperature tar may be freed from water and, for applications in depth, from volatile constituents.

Abstract: 621,383. Automatic - feed weighers. RITTER CO., Inc. Jan. 31, 1946, No. 3177. Convention date, Sept. 27, 1943. [Class 143] [Also in Group XXIX] A device for automatically filling a removable container with liquid e.g. the drinking glass provided on a dental equipment stand, comprises a support member for the container mounted for movement in one direction under the weight of the container when placed thereon, yieldable means for moving the support member in the opposite direction, valve means controlling the supply of liquid into the container, and a lever mechanism associated with the support member and including a pair of interconnected levers each arranged to control the valve means whereby the application of an empty container causes operation of the valve means from a normally closed position to an open position while the subsequent additional weight of the liquid supplied to the container causes the return of the valve means to the closed position. As shown, a support 30 for a container 26 is provided at one end of a lever 61 which is pivoted at 62 and has its other end linked to a lever 66, the latter being urged downwardly, and the support urged upwardly, by an adjustably-mounted spring 71. The levers 61, 66, are coupled to valve means in a supply line leading to the container, the valve means comprising a movable valve head 48 co-operating with a fixed seating 47, and having an operating stem 49 which passes through the levers 61, 66, and is provided with independentlyadjustable abutments 73, 77, co-operating respectively with the upper surfaces of the levers 61, 66. A compression spring 80 is located between the lever 61 and the aboutment 77. When the container is placed on the support 30, the valve is opened by movement of the lever 61 and liquid is supplied through the pipe 57 to the container. The valve is closed by movement of the lever 66 when the liquid supplied to the container reaches a predetermined amount. The supply pipe 57 terminates in a nozzle (see Group XXIX) comprising a reservoir having a siphoning discharge for draining it after the container-filling operation. When a filled container is removed from its support, the liquid released during the momentary opening of the valve is retained by the nozzle reservoir.

Title: Method and apparatus for manufacture of multi-layer cylindrical shells
IPC: B21D51/24
Filed: 1961-01-27
Abstract: 909,469. Making high-pressure cylinders; winding. SMITH CORPORATION A.O. Jan. 27, 1961 [July 25, 1960], No. 3230/61. Classes 83 (2) and 83 (4). A method of wrapping sheet material in the forming of multi-layer high-pressure cylindrical structures comprises rotating the structure to wind the sheet material thereon, continuously applying a frictional drag upon the sheet as it is wound upon the structure and varying the drag across the width of the sheet to prevent skewing of the sheet. The end of a sheet 3 is welded to a cylindrical core 19 on supporting. discs 20 keyed on a rotary spindle 2. The sheet 3 is unwound from a supply coil 5 on a mandrel 31 rotatable in bearings on parallel side beams 27 pivoted at 26 on a main beam 25 and adjustbly supported at their upper ends on hydraulic cylinders 28. The sheet 3 is drawn from the coil 5 over a roller 35 through a friction brake 6, under heater means 7 on to the core 19. The brake 6 is keyed at 40, Fig. 8, in grooves 41 in end plates 42 and its movement along the grooves 41 is resisted by hydraulic cylinders 43. The pull on the brake 6 may thus be measured. The brake 6 includes lower friction elements 47 pressed towards upper friction elements 48 by hydraulic cylinders 45, which may be individually adjusted. The sheet 3 is thus stressed and straightened between the brake and the core 19. The heater means 7 comprises a transverse row of individually adjustable gas burners. As the sheet is wrapped on the core 19 it cools and shrinks. An end frame 10 for the spindle 2 may be swung away from the spindle. The layers of the wound sheet may be welded.

The gear wheel has an annular recess enlarged at intervals tc form pockets to receive springs 7 and end cap: 8 between which are quill arms 9 secured at 10 to the driving wheel 1. The annular recess is closed by a plate 12. The gear wheel is enclosed in two-part gear-box 13 partly filled with oil into which the wheel dips. The rotation of the wheel transfers the oil upwards a part being trapped in a pocket 14 whence it flows through an opening 15 and channel 16 to an overflow 17 which conveys it to a gutter 18 welded to the plate 12. From this gutter, borings 19, 20 convey the oil to the inside of the spring casings by centrifugal force. Surplus oil mainly flows out through openings 11, provided for the arms 9, and is thrown on to the cylindrical wall 21 of the gear box. To prevent escape of oil from the driving wheel side, a labyrinth is provided consisting of rotating splash discs 22, and stationary, trap discs 23 with grooves 24. Oil leakage at other parts, e.g. 25, 26 is prevented by felt rings. Clean oil in small quantity is supplied to the roller bearings through a few openings 29 in a spacing ring 28 to which it is fed by a wick. The selfaligning bearing may comprise taper rollers, or one cylindrical and one self-aligning, or one roller and one ball bearing. The Specification as open to inspection under Sect. 91 states that it is important that the forces from the motor pinion and the quill arms 9 should be applied to the gear wheel 6 at a point which does not lie outside the end surfaces of the bearing 4. This subject-matter does not appear in the Specification as accepted.
