Abstract: 1459399 Rotary parlour SIMPLEX OF CAMBRIDGE Ltd 28 March 1974 [28 March 1973] 14917/73 Heading AIM A rotary parlour comprises a platform carrying compartments, each of which is provided with two closable openings, in which an animal enters a compartment through one opening and leaves through the other opening in a forward direction at a loading and unloading station, or stations, on the outer periphery of the platform. In one embodiment, Fig. 1, for cow milking, a hexagonal platform 1 is intermittently rotated by a motor 16, gear box 17 and chain and sprocket drive 18 on a plurality of wheels 2 running on a circular track 3. Each facet of the platform 1 is provided with a compartment 5 containing four stalls. A compartment comprises a breast rail 6 supported by stanchions (not shown), which also support mangers 8, and a shaped rump rail 9 supported by stanchions 10. The shaped rump rail 9 allows an operator standing on the platform side access to the udders. Cows enter the compartments 5 through an up-and-over gate 11 mounted between the rails 6, 9, and leave through a swing-gate 12 mounted on a pivot 13. A gate 14 allows operator access to the central area 15. The platform 1 can be rotated through 60‹ in the direction of arrow "A" at predetermined time intervals to bring the entrance and exit gates 11, 12 of each compartment into register with the loading and unloading station 21. During each stationary period a drawbridge 22 communicating with an entrance race 23 and an exit race 24 is lowered onto the platform to allow unloading compartment 5 via the exit race 24 by opening gate 12 to position 12' and subsequently to load the preceding compartment via entrance race 23 after closing gate 12 and raising gate 10. In another embodiment, an annular intermittently rotatable platform 31 is provided with a plurality of radially extending stalls 32. A stall comprises a breast rail 33, carried by the platform, which supports mangers 34, radial partition rails 35 having openings closable by gates 36, and a recess 37 for operator access guarded by a rail 38 at the platform perimeter 31. A fixed rump rail 39 closes to cow access those stalls not in register with the loading station 41 and unloading station 42. Drawbridges 43, 44 communicate with entrance and exit races 45, 46 respectively. In operation the platform 31 is rotated in the direction "B" at predetermined time intervals to bring two adjacent vacant stalls into register with the entrance and exit races 45, 46. During each stationary period a gate 36 is opened to allow unloading of the stall adjacent to an empty stall by a cow walking forward to the right via the open gate 36 and the vacant stall, whilst the other vacant stall is loaded. Closure of the loaded stall by the rump rail 39 occurs when the platform is next rotated.

Title: Improvements in and relating to telautography of phototelegraphy
IPC: H04N1/00
Filed: 1923-06-07
Abstract: 226,244. Bartholomew, H. G., and MeFarlane, M. L. D. June 7, 1923. Copying-telegraphs; distributor systems. - Message signals of the usual character are transmitted simultaneously with telephonic, oscillatory, or alternating currents serving to transmit a visual representation. A multiplex distributor may be employed, certain of the channels being used for the message signals and others for the copying-telegraph signals, and the message signals are used to maintain synchronism. In the case of telephonic transmission, e.g. as described in Specification 182,928, the telephonic currents are distributed to the line through the copying- telegraph channels, which, to enable a more rapid transmission to be effected, may be subdivided to transmit a multiple of the number of signals transmitted by each message channel. In such transmission five different notes of frequencies between 512 and 256 per second and corresponding with five different tones in the visual representation may be used. Such notes may be produced by buzzers brought into operation by a tape perforated in accordance with the tones to be transmitted. In the case of transmission by oscillatorv currents, the transmitting stylus described with reference to Fig. 1 of Specification 182,928 may constitute a keying mechanism for controlling the emission of C.W. signals of durations corresponding to the sizes of the dots in the representation, and such signals may be used to produce audible signals of which a dictaphone intermediate record is made. A perforated tape or other intermediate record may be produced as described in Specification 197,402, and such records are used to reproduce the representation e.g. as described in Specifications 166,917, 182,928, 195,577, and 197,402.

Title: Toothbrush
IPC: A61C17/40
Filed: 1965-04-08
Abstract: 1,081,021. Toothbrushes. SUNBEAM CORPORATION. April 8, 1965 [April 22, 1964], No. 15018/65. Heading A4K. A toothbrush includes an electric motor in its handle (10) to move its brush head (12) in a circular or elliptical path, the head (12) carrying tufts (18) each formed of interspersed long and short bristles (22, 24). In use, the free ends of the long bristles (22) become anchored in tooth depressions so that the circular movement of the brush head (12) causes each long bristle (22) to generate a conical path, the short bristles (24) following the brush head movement over their whole length. The long bristles (22) thus have their effective stiffness increased by wrapping around the short bristles (24) until their frictional anchorage in the tooth depressions is overcome and they perform a rapid sweeping motion. The short bristles may be thicker than the long bristles.

Title: Process for the production of cellulose acetate threads, fibres, films and analogous articles by extrusion into an aqueous coagulating bath
IPC: D01F2/28
Filed: 1956-05-22
Abstract: Threads, films and like products are produced by extruding an acetic acid solution of cellulose acetate into an aqueous coagulating bath, subjecting the extruded liquid-impregnated products to a temperature above 90 DEG  C. in a heated zone while removing from the zone fluid material issuing from the products, and washing and drying the products.  The thermal treatment may be effected at temperatures up to 180 DEG  C. or over, preferably 100-120 DEG  C., and at atmospheric or superatmospheric pressure. The acetic acid solution of cellulose acetate may be that resulting from acetylation and, prior to extrusion, the solution may be subjected to known treatments such as stabilization, hydrolysis, neutralization of the catalyst and filtration. During the thermal treatment the products may or may not be allowed to shrink or may be stretched.  In an example, an acetic acid solution of cellulose acetate (acetyl value as acetic acid 60.5 per cent) of 13 per cent concentration, which has been obtained directly from the acetylation of cellulose in the presence of sulphuric acid as catalyst, is extruded, after the catalyst has been neutralized and after filtration, into an aqueous coagulating bath containing 25 per cent of acetic acid. The resulting strongly swollen thread issuing from the coagulating bath, and containing 400 parts of dilute acetic acid for every 100 parts of dry cellulose acetate, is stretched by 15 per cent between two rollers and is then passed through the interior of a tube which is at an acute angle to the horizontal and the interior of which is at 100 DEG  C.  During its passage through the tube the thread is allowed to shrink by 2 per cent and the period of residence of the thread in the tube is one minute.  The acid released from the thread during its passage through the tube runs down the latter by gravity and is discharged from the lower end of the tube at a concentration of 25 to 27 per cent.  The remainder of the acid in the thread is removed by counter-current washing of the thread with water.  Since most of the acid is removed from the thread in the form of a relatively concentrated aqueous solution, the cost of its subsequent recovery is reduced.  The thermal treatment of the freshly extruded threads also increases their safe ironing temperature, and their affinity for plasto-soluble dyes is improved.
