[Class 78 (v)] [Also in Group XIV] A device for guiding the draw-cords of curtain suspension means around corners comprises a guide carrying member 23 adapted to support a pulley 30 rotatable on a vertical axis adjacent to the bend of the rail 1, and a pair of narrowly-spaced jaws 33a, 29c mounted about the pulley and adapted to permit passage through them of the cord-gripping device 35, 36 on the master runner. The operating cord 14 depends from two vertical pulleys 19, 20 at the outer end of the rail 1, passes over a horizontal pulley 16 at the inner end and at the bend or corner 1a passes over guide pulleys 27. 30 mounted on the metal block 23 with a depending bifurcated lug 24 which fits over the upper edge of the rail and is secured by a set screw 25. The pulley 30 is mounted on a bolt 32 so that it will yield vertically against a spring 34 when the cord-gripping device 35, 36 of the leading runner 8 passes over it. The mounting 29 for the pulley is bent upwardly at 29c and a loose plate 33 bearing upon the upper side of the pulley is bent downwardly at 33a to form curved lips between which the cord-gripping device is guided. The cord-gripping jaws taper towards the ends so as to slide easily between the lips 29c, 33a.

Abstract: 1479009 Automatic exchange systems B N SARMA 12 July 1974 31008/74 Heading H4K A PBX having a non-blocking PCM, TDM, Time Switching network is arranged to permit three party connections to be set up. Speech signals from incoming trunks, PBX subscribers circuits and operator circuits are multiplexed on to respective 32 slot P.A.M. highways and are then all combined in 8 bit parallel PCM form on to a single 512 slot parallel highway which extends to a pair of 512 location speech stores 902, 903. These stores are writer, and read, in alternate frames in generally known manner under the control of write circuitry (not shown) and a connection store 906. However to provide for three-party connections combiner circuit 904 and a second connection store 907 are provided. Hence in each time slot, the connection store 906 is read and a location of store 902 or 903 is read out to the combiner 904. Connection store 907 is then read to see if a second location of store 902 and 903 is to be read in the same time slot and if so the second location is read out to combiner 904. The combiner 904 then either reads the larger of the two PCM codes on to a 512 slot highway extending to a demultiplexer or alternatively adds the two codes together. The arrangement is particularly used for Operator break-in.

Title: A method of obtaining important constituents from pollen
IPC: A23L21/20
Filed: 1964-08-04
Abstract: Nutritionally and medicinally valuable materials are extracted from pollen by treating with a mixture of water and a water-miscible organic solvent, digesting the mixture of extract and pollen grains with a mould of the genus Mucor, and removing the mould and pollen to leave the required extract.  The preferred solvent is acetone, or may be ethanol.  After separating the pollen grains, they may be defatted with acetone or ethyl ether, further digested with the Mucor remaining on the pollen and re-extracted with the water-solvent mixture to give a further yield of the required extract.  The digestion process is said to break down allergenically active and undesirable proteinaceous components to harmless lower molecular weight products.  The pollen extracts are useful as a source of amino acids, vitamins and deoxyribosides; the pollen used in the Examples is obtained from Phleum pratense (Timothy grass), and the mould is Mucor hiemalis.

Title: Improvements relating to automatic control systems, especially for machine tools
Inventor: SPENCER ROLF EDMUND
IPC: G05B19/33
Filed: 1955-11-04
Abstract: 847,367. Automatic control systems. ELECTRIC & MUSICAL INDUSTRIES Ltd. Oct. 25, 1956 [Nov. 4, 1955], No. 31536/55. Class 38 (6). An automatic control system for a recordcontrolled machine tool comprises an autotransformer with a series of taps and a series of output contacts and means whereby the input to the auto-transformer can be moved dependent on the position of the workpiece whereby the potential supplied by the autotransformer to one side of a comparator under the control of a command signal varies while the potential supplied by the auto-transformer from a point opposite the input remains substantially constant. In a system having many of the features described in Specifications 799,356, 802,472 and 846,381, the first recorded digit positions a wiper SWD1 while the lower order digits are applied to the associated command lead over transformer TR10. The position of the workpiece is caused to drive the wipers of switches SWA and SWB. the latter supplying a potential to transformer TR2, TR3 according to the fine adjustment of the workpiece. Switch SWA indicates the highest order of movement and energizes one of relays RLA-RLK to connect supply current to a selected pair of input terminals on auto-transformer TR1. The related contact, say RLA3 connects a point diametrically opposite to the input terminals to a position analogue lead PA so that if the input potential is 10k the lead PA receives 5k, plus or minus a potential supplied by transformer TR2 or TR3. Wiper SWD1 makes connection with a selected contact, say B6, and receives a potential appropriate to the relationship of this contact to the operative input terminals. The potentials on the command and position analogue leads are compared at MA to drive a servomotor M. As the workpiece moves so does wiper SWA1, the potential on PA remains substantially constant but the potential on the command lead varies as the input to the auto-transformer moves.
