Title: Method and machine for the cutting of workpieces of semi-circular cross-section, more particularly insulating bushings for pipelines, from blocks of soft materials
IPC: B23D37/00
Filed: 1958-09-02
Abstract: 844,230. Drilling. MULLER, P. R. Sept. 2, 1958 [Sept. 3, 1957], No. 28195/58. Class 83 (3). In a method and machine for producing semicircular workpieces, in particular insulating-bushes for pipe-lines, the machine comprises a tubular cutter driven from a headstock, and a support for the material from which the work is cut, mounted at an angle to the horizontal axis of the cutter and intersecting the axis. A bedplate 1, Figs. 1 and 2, supports a headstock 2 having rotatable means 3 for driving a tubular cutter 4 secured thereto. A supporting-rod 8 adjustablymounted on a bracket 7, passes through the cutter and supports the work during the cutting- operation. A block of material 14, Fig. 3, having a previously-machined aperture 15, is ;placed on the face 10 of a table 9, Fig. 1, and is located transversely of the cutter 4 by a guide 13 co-operating with the aperture 15. The block 14 is moved over supports 12 to cut the bush, and is then lifted clear of the cutter 4. A subsequent operation may be performed on the block 14, using a larger cutter and a larger guide 13. For a block without a previously-machined aperture, an adjustable guide 11 is used.

Title: Improvements in the production of reinforced endless rubber belts or bands
IPC: B29D29/08
Filed: 1955-10-11
Abstract: <PICT:0843461/IV(a)/1> An endless rubber band consisting of a unitary rubber layer having a helical cord reinforcement embedded completely therein is manufactured by winding the cord on to a layer of plastic natural or synthetic rubber composition on a cylindrical mandrel, the tension of the cord being controlled during the winding so that it cuts into and is completely embedded within the thickness of the plastic layer.  After the winding is completed the mandrel and the layer thereon may be wrapped in wet cloth and the layer vulcanized in a steam chamber.  The reinforced rubber tube so obtained may be cut into bands for use as draft aprons for conveying textile fibres.  A cord 2 of nylon, polyethylene terephthalate or other synthetic fibre is led from a spool 9 through tensioning apparatus comprising a guide 10, an arm 11 of a spring loaded constant torque device 12, and pairs 13, 14 of spring loaded friction discs.  From the discs 14 the cord 2 is passed around a guide 19 and through a bath 20 containing rubber solution to be wound on to a tube 1 of plastic natural or synthetic rubber composition mounted on a rotating mandrel 3.  The bath 20 and the cord tensioning apparatus are traversed on slideways 6, 7 parallel to the mandrel, by a lead screw 8.  A synthetic rubber composition of the desired plasticity may comprise 100 parts by weight of butadiene-acrylonitrile, 50 parts carbon black or silica, 35 parts of a plasticizer such as tricresyl phosphate or dibutyl phthalate, and vulcanizing ingredients.

The generator-absorber 1, Fig. 1, which is counterbalanced by a weight 8 and rocks about a pivot 9 at each change of phase, is provided with a cooling pocket 3 connected by a pipe 4 to a trap 5 and condenser 6 of a sealed heat transfer system adapted to move with the generator-absorber The condenser, trap and connecting pipes are inclined relatively to one another and to the pocket 3 in such a manner that the transfer medium is retained in the condenser while evaporation proceeds during an absorption phase, with the generator-absorber in the raised position r, and flows into the trap 5 when the system rocks to the lowered position l for generation, flows from the trap to the pocket when the system rocks again to initiate another absorption period. A double rocking generator-absorber system may be provided with heat transfer systems connected to a common condenser element, or, as shown in Fig. 3, a divided condenser element 8, 9 may be employed, the cooling pockets 1, 2 of the generator-absorber vessels being connected to traps 10, 11 by separate vapour and liquid conduits 6, 12 and 7, 13, and to the condensers by crossed pipes 4, 5, so that the condensate of one system flows into the pocket of the other.

Abstract: 1,083,905. Data transmission; diversity systems. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. July 8, 1965 [July 11, 1964], No. 28992/65. Headings H4L and H4P. In a system which eliminates the effects of error bursts by sending the same data over two multiplexed channels with a relative dealy t greater than the duration of the bursts, means is provided for ensuring that the demultiplexer operates in the correct phase. The demultiplexer 9 feeds a selector switch 14 direct and via a delay 12 equal to that at the transmitter. The selector normally feeds the delayed channel 10 to the receiver output but, when an error is detected by comparison (20) of the selector inputs, the selector changes to the other input 11 after a delay t and back again after a further delay t, thereby removing the error burst from the output. Detection of error also enables a counter which counts the number of equalities in the input and output of delay 20 during the period t. If these exceed a certain number it is assumed that the phase of the demultiplexer is incorrect and so it is reversed in phase.

Abstract: 977,305. Data stores. GENERAL TIME CORPORATION. Dec. 30,1960 [Dec. 31,1959], No. 29509/ 64. Divided out of 977,301. Heading G4C. A buffer store used in the data collection system described in Specification 977,301 comprises a plurality of serially connected stages each of which is capable of storing an alpha-numeric character,the first stage receiving input characters and the last stage delivering output characters, and means for shifting characters from the first stage through the various succeeding stages to the last empty stage prior to the output of the store, whereby whenever any characters are stored, a character is always available in the last stage. Each stage comprises six bi-stable circuits (not shown) for storing a character and an associated bi-stable circuit 160 or 168 which is set when the corresponding stage contains a character. When a character arrives, a synchronizing pulse is produced on lead 146, and after shaping is used to enter the character through gates (not shown) controlled by lead 152 into the first stage. At the same time, bi-stable circuit 160 is set by the pulse on lead 159. If the second stage is empty, the "O" output from bi-stable circuit 168 enables AND gate D8 and the synchronizing pulse passes through this gate OR gate D12 and delay D14 to reset the first stage (leads 163, 174) and transfer the character to the second stage. In a like manner the character is transferred from stage to stage through the store until there is no longer an empty stage to which it can be transferred. In the embodiment shown, only two stages are provided, but Fig. 4 (not shown) illustrates a store having a larger number of stages. If the second stage contains a character, AND gate D8 is not enabled, and the character remains in the first stage. When the second stage is reset as a consequence of the third stage becoming empty or the output device e.g. a tape punch calling the character from this stage, the reset signal on lead 184 passes through AND gate D24 which is enabled by the "1" or."stage full" output of bi-stable circuit 160 and the character is transferred from the first stage to the second stage as before. When a master reset signal is applied on lead 172 delay circuits D14, D46 act as free-running oscillators and supply a continuous train of reset pulses to their respective stages, whereby no spurious signals will be in the store when data is next received.
