The carriage 5 may be formed of two parts 5A, 5B interconnected by a piston and cylinder device 7 whereby, in use, the means 9 may be operated as the carriage moves along the at same speed as the conveyer 1, and then the part 6B of the carriage may be accelerated with respect to the conveyer by actuating the device 7, the means 8 thus being brought over the holes formed during operation of the means 9. Alternatively the means 8 and 9 may be combined such that a hole forming punch is provided which acts through an air valve as it is fitted. The means 8 and 9 may be arranged to operate before or after the cutter 10. A conveyer belt 14 is provided to supply air valves to the means 8, and the valves may have rubber bases to which adhesive is applied by a device 13.

When the last of a row of a predetermined number of shells is present in the space 25, the plate 10 is retracted. This causes the shells to be aligned against one of the members 13 and the row of shells is thereby caused to drop on to a conveyer belt 14. To enable the row to proceed on the conveyer 14, the other member 13 is lifted clear (Fig. 2, not shown).

Title: Apparatus for supplying liquid animal feed to feeding stations
IPC: A01K5/02
Filed: 1972-10-13
Abstract: 1400736 Controlling liquid animal feed SCHMEING Gebr 13 Oct 1972 [13 Oct 1971 27 May 1972] 47419/72 Heading AIM [Also in Division F2] Apparatus for supplying liquid feed or water to an animal feeding station comprises a supply pipe and closure means controlling flow from the supply pipe to a take-off pipe, the operation of the closure means being performed in two stages, at least the first of which is controlled by pressure in the supply pipe.  In the embodiment shown in Fig. 5, pressure in a supply pipe I raises a valve 28 allowing the liquid to enter a container 20 until a float 23 rises to cut off further entry by seating a valve 29. Further pressure increases in the pipe 1 results in the valve 29 being pushed further into the conduit 21, thus raising a ball 32, by the action of the valve 28 contacting an arm 33, and releasing the feed into a feed pipe 3. A suitable signalling device results in the reversal of the pumping action creating a negative pressure in the pipe 1 and the weight of the float 23 returns the valve 28 to its position in contact with the conduit 21 allowing the ball 32 to return and seal the entrance to the feed pipe 3. In an alternative arrangement the pressure in the supply pipe 1 acts on a ball 6 to depress a movable feed pipe 3 until the ball is arrested by a seat 14. The legs 19 of operating elements 17 are thus pivoted outwardly beyond supports 5 which previously shielded them and they may now be raised further by an animal to withdraw the top of pipe 3 out of engagement with the ball 6 and thus release the liquid food into the feed pipe 3.

[Also in Division G3] Workpiece control apparatus in a rolling mlil comprises two roll force sensing devices 112 and 114 which, by transposing the roll force into strip thickness using the mill spring characteristics, detect errors in the strip thickness at each edge, and a roll shape senser 116 which measures the bending force on backing roll 110, the sensing devices actuating the screwdowns of the mill to correct the errors. The error signal from the senser 116 passes through a gate 128 only when the signals from devices 112 and 114 are substantially the same. Also controlled by the sensing devices are roll heating and cooling means (Fig. 2, not shown). Spaced heating coils 30, 32 and 34, and fluid nozzles 36, 38, and 40 control the temperature and hence the profile of the rolls.

Abstract: 1433116 Production of sintered aluminium sheets AGENCY OF INDUSTRIAL SCIENCE & TECHNOLOGY 4 Nov 1974 [8 Nov 1973] 47542/74 Heading C7D Sintered Al sheets are produced by sintering green compacted Al sheets at 300-600‹C in air or an inert gas, rolling the sheet before the temperature falls below 300‹C and then annealing. The steps of rolling and annealing may be repeated to obtain the required thickness. Laminated sheets can be produced by stacking the green sheets prior to sintering and reinforcing fibres such as Cu wire, piano wire, C or BN fibres or whiskers of α Al 2 O 3  or SiC may be placed between the green Al sheets. The process is a continuous method in which Al powder is fed from a hopper through a pair of rolls, then through a sintering furnace followed by a rolling  mill and annealing furnace. Annealing may be at 400‹, 500‹ or 550‹C.

Title: Acoustic leak location and detection system and method
IPC: G01M13/00
Filed: 1973-10-12
Abstract: 1452788 Locating noise sources EXXON RESEARCH & ENG CO 12 Oct 1973 [6 Nov 1972] 47734/73 Heading G1G A noise source in a fluid-container is located by forming the instantaneous product of the outputs of two spaced acoustic sensors and monitoring variation of the short-time average of the product in dependence on the position of the sensors. For locating a fluid leak in a tank, sensors mounted at the ends of an arm are lowered into the tank and are slowly rotated in a first plane (or the outputs of several sensor pairs are switched to simulate rotation). At any instant, the short time average obtained by integrating the output of a phase-sensitive multiplier coupled to a sensor pair will be low unless the noise source constituted by the leak lies in a plane normal to the line joining the two sensors of the pair. The sensor orientation giving a maximum metered value of the average thus identifies a plane containing the leak. By repeating the above procedure with the rotation in a plane orthogonal to the first plane and at different regions in the tank, various planes containing the leak can be found and represented on a scale map of the tank, their intersection identifying the leak location in three dimensions. The multiplier output is monitored on a CRT to detect the presence of non-random noise sources, e.g. rotating machinery, which would interfere with the locating. In an embodiment for detecting a pipe-line leak the two sensors are arranged, between baffles which exclude ambient noise travelling in the longitudinal direction of the pipe-line, in a pipe-line pig. The integrated sensor output product is a maximum when the sensors are equidistant from the leak.

Abstract: 1,125,579. Electrophotographic materials. GEVAERT-AGFA N.V. 25 Oct., 1966, No. 47895/66. Heading H1K. An electrophotographic material is made from a coating mix comprising a photo-conductor dispersed in an aqueous solution of (a) a melamine-formaldehyde condensate and (b) a salt of a volatile base and an alkyd resin containing acid groups, the acidic form of the resin being insoluble in water. Several melamineformaldehyde condensates and alkyd resins are identified. The preferred base is ammonia but hydrazine, morpholine, piperidine, and many acyclic aliphatic amines are specified. When the mix is dried on a support the base is released and cross-linking occurs between the resins. Cross-linking may be accelerated by heat or by including free formaldehyde or a formaldehyde-releaser in the mix. In the examples zinc oxide is used as photo-conductor, supports are of aluminium-coated paper or of glassine paper, and monobutyl phosphate may be added to increase the dark resistivity of the zinc oxide. The Specification makes reference to others disclosing known sensitizers, supports, resistivity modifiers &c. which may also be used.
