Title: Improvements relating to apparatus intended particularly for feeding animas
IPC: A01K29/00
Filed: 1965-02-01
Abstract: 1,100,974. Animal feeding apparatus. M. A. J. LEGRAIN and A. F. LEGOURD. 1 Feb., 1965 [1 Feb., 1964; 13 April, 1964; 17 Aug., 1964; 10 Jan., 1965], No. 4349/65. Heading AIM. [Also in Division B1] Feeding apparatus for young stock comprises a mixer 1 containing a mixing device 25 driven by an electric motor 4 and which is supplied with milk powder from a hopper 7 and water from a tank 8, control means being provided so that the powder and water are supplied and the motor activated when the weight of the feed mixture in the mixer falls below a predetermined amount due to consumption of the feed at the teats 6. The control means comprises a manometric device 27 sensitive to the pressure of the liquid feed within the mixer 1 and comprising an electrical contact which closes when the feed level falls to activate the motor and open an electro-valve 12 controlling the water supply. The shaft 3 driven by motor 4 also causes shoot 15 to vibrate under the action of cam 21 so that powder falls into the mixer through an adjustable opening 13. An agitator 23 is connected to shoot 15. The mixer 1 is preferably of glass so that the feed level may be viewed and the teats 6 are of flexible material and have a curved external shape and a cruciform passage for the liquid feed. In a modification the motor drives an agitator screw within the powder hopper the powder falling to the mixer via a rotating disc and an Archimedian screw. The mixer is provided with a rotating ring on to which the water falls so that it is directed on to the sides of the mixer.

Title: Improvements in boot or shoe rough rounders and channelling machines
IPC: A43D43/02
Filed: 1922-02-15
Abstract: 200,540. Johnson, L. E., Peterson, 0. T., and Popp, L. A. Feb, 15, 1922. Trimming; channelling.-In a sole rough rounding and channelling machine of the type in which the chanelling knife is mounted on the work support, and a presser foot is positively actuated to move its end into position to grip the work upon the support and move therewith to feed the work during the return stroke of the channelling knife, a relatively fixed welt-edge gauge serves also as a cutting block for the roughrounding chisel whilst the latter holds the work stationary during the action of the channelling knife. As shown, cam on a shaft 13, Fig. 1, operates a lever 29 having at its upper end a bearing slidably engaging the shank 35 of a work support 71. The support is pressed upwards by a spring 37 and depressed, to allow worls to be inserted, by a handle 39. The sole being operated on is pressed upwards against a welt gauge 60, Fig. 2, provided with a curved edge and secured beneath a crease guide or shoe-positioning gauge 42 adjustable by a handle 47, Fig. 1, and clamped in adjusted position by a screw 50, Fig. 2. The guide 42 is provided with an opening 52 in which works the end of a work-feeding presser foot 54 having a four motion movement derived from an eccentric 17 and pivoted guide 57. An eccentric 16 reciprocates a trimming chisel 62 the cutting edge of which co-operates with the welt guide 60. which is made of soft metal such as bronze. The work support and channelling knife are, adjusted to or from the sole edge by a handle 88. The work support, Fig. 5. is pivoted with slight play at the upper end of the shank 35, the channelling knife 74 being adjustably held in a groove by a screw operated wedge 75. If the machine is desired to trim without channeling the knife 74 may be replaced by a member with a similar shank but provided with small serratons for cooperating with the presser foot in feeding the work. Specification 200,784 is referred to.

Filed: 1934-02-12
Abstract: 416,261. Re-working worn rollers ; upsetting. TOMLINSON, F., South Holme, The Springs, Bowdon, Cheshire. Feb. 12, 1934, No. 4535. [Class 83 (iv).] A worn non-ferrous printing roller is reconditioned by subjecting it to longitudinal compression to thicken the walls, and increase the external diameter or decrease the internal diameter or both while consolidating the metal. The roller 5, on a tapering mandrel 6 is inserted in a die or container 7 and pressure applied through a sleeve 9 to compress the roller longitudinally and cause it to fill any space existing between itself and the container or the mandrel or both. In the first instance, the tapered mandrel may be displaced in the roller to aid its expansion. The roller is subsequently rolled, drawn or hammered to suit its hardness and density for engraving or etching. The process may be applied to new rollers for fitting them on mandrels.

Patent GB-1385063-A (GB)
Title: Yarn production
IPC: D02G3/40
Filed: 1972-02-01
Abstract: 1385063 Spinning yarn AHMEDABAD TEXTILE INDUSTRY'S RESEARCH ASSOCIATION 1 Feb 1972 4640/72 Heading D1F A method of spinning yarn from a roving of cotton fibres in which the roving is drafted followed by combined twisting and winding, is characterised in that the roving is subjected to a wetting treatment with water prior to drafting and is drafted in wet condition. The wetting increases the inter-fibre cohesion and thus less twist is required for a given strength yarn and the production rate is therefore increased. The roving may be wet while subjected to the combined twisting and winding operation, the package being subsequently dried. The roving may be wet by passage through a trough of water with or without wetting agents, or by immersion of a bobbin of roving in a trough of water with or without wetting agents. The roving is drafted between two pairs of rollers and is preferably wound on a ring spinning machine although any conventional combined twisting and winding system may be used.

Abstract: 342,547. Pneumatic dispatch apparatus. LAMSON PNEUMATIC TUBE CO., Ltd. and HERRING, R. L., 132, Cheapside, London. Feb. 15, 1930. No. 5133. [Class 116.] In a central station having a series of incoming terminals arranged in one or more groups and a similarly arranged series of terminals for returning carriers to their respective points of origin, a conveyer being arranged between the groups, the carriers are delivered from the incoming terminals to the conveyer automatically and are transferred to a single group of operators stationed at the dispatch terminals who act as receivers, deal with the contents and then act as dispatchers. Each of the receiving terminals which are arranged in groups such as A, B, C, D, Figs. 2, 3, is preferably fitted with a device for separating ordinary and " sanctions " carriers, i.e. those which must be passed to an authorizer before being delivered to the operators. The ordinary carriers from the groups A, B, C, D pass down gravity shoots 19,21 to their respective tracks c, b, d, a formed by partitions on a moving endless belt conveyer 10, whilst " sanctions carriers from the groups A, C and B, D pass respectively to tracks f, e on the lower side of the belt and are conveyed in a direction opposite to that of the ordinary carriers to the suction tubes 27, 28 which convey them to the authorisers' station. The ordinary carriers pass to the operators, who are situated near the dispatching terminals E, where deflectors such as 22<1> and shoots 23 may be provided to deliver the carriers to the appropriate operators. After having been dealt with by the authorisers, " sanctions carriers are returned to terminals 29 at the operator's station, each such terminal having an opening approximately the length of a carrier so that a returned carrier is held therein until picked out by an operator, thus ensuring that sanctions carriers are dispatched in the order in which they are received. The suction tubes 27, 28 may be replaced by gravity shoots or moving conveyers, whilst if " sanctions " carriers are not required, the underside of the belt mav also be used for cash carriers. Further, movable stops may be employed to divert all the carriers to any given operator or operators. Specification 180,365, [Class 116, Shop &c. accessories], is referred to.
