Title: Method of balancing electric cables
IPC: H04B3/28
Filed: 1927-10-20
Abstract: 304,367. Standard Telephones &. Cables, Ltd., and Collard, J. Oct. 20, 1927. Induction, preventing and minimizing. - Inductive effects in a multilayer cable due to external fields of force, e.g. due to neighbouring power lines, occur when the admittances of the two sides of a circuit to adjacent conductors are unequal, and the E.M.F. induced is substantially the same for each conductor. If the quads are cross-spliced between layers. each conductor is at substantially the same potential. and it is sufficient to determine the admittance unbalance to earth or sheath of the two sides of each circuit, while maintaining the remaining conductors at the same potential as the conductors under test. This is carried out by the bridge shown in Fig. 1, 1, 2 being the circuit under test, and A representing the remaining conductors. The effects are then reduced by cross splicing according to the measurements made. If. on the other hand, there is only cross-splicing in individual layers, the potential of the conductors increases progressively from the sheath to the innermost layer, and it is necessary to balance the two sides of each circuit separately as regards the. admittance to each adjacent layer. These unbalances are measured by the bridge shown by replacing the earth connection by a connection to the conductors of each adjacent layer in turn. Specification 203,870 is referred to.

Title: Bandage
IPC: A61F13/00
Filed: 1960-08-12
Abstract: A bandage is made from an absorbent fibrous layer enclosed in a crepe bandage comprising kinked threads, as in the parent Specification, the edge portions of which overlap each other.  The absorbent layer is preferably formed from non-woven cellulosic fibres interlocked by a "needle loom" process, whereby a proportion of the fibres are forced through the mass in the direction of its thickness to bind it together.  The kinked threads of the wrapper readily cling to the surface of the absorbent layer and to themselves, over the area of overlap, thereby providing a unitary bandage which adheres to itself during use.

Title: Improvements in or relating to the recovery of glycerol
Inventor: BLAIR JAMES
IPC: C12P7/20
Filed: 1952-10-03
Abstract: <PICT:0723230/III/1> Glycerol is recovered from a concentrated fermentation liquor by mixing therewith a granular material in an amount and for a time sufficient to form a free-flowing mixture, continuously agitating the mixture while heating it under reduced pressure to distil glycerol-containing vapours therefrom, and continuously replacing the spent and removed mixture by fresh free-flowing mixture.  The time of contact of the glycerol with a heated surface is thus kept to a minimum.  The vapours may be wholly condensed and the glycerol recovered by distillation, or the glycerol may be directly recovered by fractional condensation of the vapours. The fermentation liquors used are obtained by the fermentation of carbohydrates such as sugars, starch and molasses.  The granular materials specified comprise sand, coke, Fuller's earth, kieselguhr and anhydrous sodium sulphate.  The mixture may be agitated by any mechanical means such as by rakes or paddle stirrers or by vibrating the vessel containing the free-flowing mixture.  The heating may be effected by a steam-heated jacket, radiant heat or high-frequency heating.  The granular material may be recovered for re-use by washing with water and drying and, if necessary, burning off the residue on the granules.  In a suitable apparatus, a mixture of concentrated fermentation liquor comprising glycerol, water and solids, obtained by concentrating and stripping the liquor obtained by fermenting blackstrap molasses, together with kieselguhr in given proportions, is fed into a hopper 1 on to a feed tray 2 attached to a tube 3 having a heating jacket 4 maintained at 180 DEG -200 DEG  C. by steam heating.  The pressure in the tube is maintained at two mms. The jacketed tube is mounted on spring leaves 19 on a rigid support 20, the leaves being at an angle of 70 degrees.  The tube is vibrated by means of the piston 21 of a hydraulic pump 22 acting at right angles to the leaves 19, a vibration frequency of 1,500 cycles per minute being used.  The tube 3 is connected to an extension piece 10 having an outlet 11 for spent material.  The vapours pass into a cyclone 13 p  for removal of dust at 14 and then to a condenser 16, condensate collecting in a receiver 17.

Abstract: 728,689. Turning-gear. C.A.V., Ltd. Nov. 11, 1953 [Nov. 12, 1952], No. 28485/52. Class 7(5). In an engine starting mechanism comprising he combination of an elastic energy-storing component, such as the cylindrical rubber or ubber-like member b, Fig. 1, an arrangement of manually-operable gearing for imparting angular movements at different rates to the ends of the member b, and a pinion q for letachable engagement with an engine wheel r and operable by the member b, a clutch h is provided which, when engaged, enables simultaneous angular movements to be imparted to the ends of member b and when disengaged allows the energy to be released. The housing a contains the member b, the latter having a gear ; at one end and a smaller diameter gear d at the other end, the gears being bonded thereto and meshing with gears f, g, respectively, of different diameters which are mounted upon a shaft e ; the gear g which is connected to the shaft e by the clutch h that is operable by a hand lever j, is rotatable by another hand lever m through a worm k. A gear n, which is also secured to the shaft e, engages a small gear o on the output shaft p that extends through the member b. Rotation of the lever m both imparts a different angular movement to each end of the elastic component due to the different diameters of gears g, d, and f, c, to store energy therein, and causes engagement of the pinion q with the wheel r upon rotation of gears n and o to slowly rotate the engine until the clutch h is operated to release the energy in the member b. In a modification, all the gearing is arranged at one end of the elastic component. In a final modification, an output shaft p, Fig. 3, is arranged adjacent one end of a shaft u which interconnects the gear d and a plate s bonded to the remote end of the member b, the shaft u being housed in a fixed tubular bearing member v extending through the elastic component b. The elastic component may comprise a spring or springs.

Abstract: 1524807 Photographic colour printing DE LUXE GENERAL Inc 8 July 1977 [9 July 1976] 28833/77 Heading G2A A light source for a colour printer comprises an outer cylindrical housing 2 and an inner cubical housing 1. The housing 1 has the upper half of its inner surfaces covered by mirrors 8, while the lower half of these surfaces are diffusedly reflective. The upper end of housing 1 is closed by a diffusing plate 7 on which the transparency rests. Light enters housing 1 from light sources 4R, 3G, (5R), (6B) provided with infrared filters 20, 22, (20'), (24), through apertures fitted with coloured filters 21, 23, (21'), (25), and is mixed in the housing 1 to illuminate the transparency (41). The intensities of the light sources are adjusted to give a required colour balance. However, if the transparency (41) is predominately of one colour, light reflected therefrom into housing 1 upsets the colour balance. Therefore, receptors 27, 28, 28 each comprising an infrared filter, a colour filter, and a photo-sensitive element, each produce a signal fed to a computing device which provide signals which alter the relative intensities of light sources 4R, 3G (5R), (6B) so as to restore the colour balance.

Abstract: 1,186,291. Digital transmission systems. SIEMENS A.G. 18 June, 1968 [19 June, 1967], No. 28860/68. Heading H4P. In a digital data exchange which includes a channel, e.g. ECV, ACV, comprising a number of lines, each polarity change to be signalled marking a line combination unique to an address, the address of broadcast called subscribers and the direction of polarity change are stored within the exchange and a pulse generator having a period an integral multiple of the storage cycle duration controls transmission successively to the several called subscribers. When a signal is received on one of a number of input lines unit ECW marks a corresponding unique combination of lines in channel ECV. At the start of each storage cycle, unit ZSt examines register PR to determine the highest priority of the various demands for storage cycles held in it. A demand from broadcast control RSt has higher priority than one from unit ECW. If a broadcast connection is to be set up store sections SZm-SZm + 4 are allotted to the calling address. The address of SZm is stored in SZn. Subsequently arriving dial pulses are stored in the allotted sections and indicate the called subscribers to which to broadcast. When now a polarity change arrives the direction of change is stored in WR and the calling address is stored in AR. The address stored in SZn is transferred to WR so that WR now contains the address of the store containing the first broadcast address to be called and the polarity change. These are transferred to unit RSt, where a pulse generator having a period of n store cycles is started. The generator presents demand signals to register PR. When ZSt detects the demand in PR the address of SZm is read from RSt to AR and the polarity change is put in WR. Address counter AZR is incremented. The called first address is now read from SZm to WR. Via unit ACW the appropriate one of the output lines is selected and pulsed. At the next demand pulse from the generator the polarity change is sent to the second called address, determined by counter AZR and store SZm +1 as described above. The process continues until the polarity change has been sent to all the broadcast-called addresses. The exchange processes other polarity changes in the store cycles between broadcast demands.
