Title: Improvements in or relating to mechanical milking apparatus
IPC: A01J5/04
Filed: 1947-02-18
Abstract: 621,325. Cow milkers. GLACIER METAL CO., Ltd, TAIT, W. H., and OLLEY, M. Feb. 18, 1947, No. 4663. [Class 84] [Also in Group XXVI] Suction creating means for use in milking machines comprises a number of deformable conduits 1 which rest on rubber liners 4c laid in troughs 4a formed on the interior of an arcuate support 4, and rollers 8-10 carried on arms 8a-10a mounted on a shaft 11 that is positioned at the axis of the arcuate support and rotated through gearing 11a, 12a by a motor or manually driven shaft 12. The conduits are provided with couplings 1b-3b and are secured to the support 4. The rollers when in contact with the tubes squeeze them against the base of the trough and as the shaft 11 rotates apply a travelling constricting pressure to the deformable conduits so creating a low pressure in the tube behind the roller. On the cessation of the roller pressure on each conduit the pressure in that conduit is restored to that of the atmosphere. This apparatus is connected to one or more milking cups, the conduit 1 being connected directly to the milking line 5 and the conduits 2, 3 to the inflators of the cup, branches being taken off the pipes 5, 6 and 7 to operate other cups. If desired to separate each cow's milk, then duplicate sets of conduits are disposed side by side in the troughs. In a modified form, the tubes may be supported on a straight bed and the means for applying the travelling constricting pressure may comprise rollers carried on an endless chain or on a reciprocating slide.

Abstract: 1497155 Aircraft structures DEFENCE SECRETARY OF STATE FOR 22 Dec 1975 [4 Feb 1975] 4777/75 Heading B7W An aircraft structure comprises a skin 10 and parallel rectangular tubes 11 secured to the skin, and to prevent the growth of a crack (15), Fig. 3 (not shown), in the structure a sinusoidal strip 13 is contained within each tube. Each strip is formed of carbon-fibre-reinforced cured plastics and when contained in the tube is constricted so as to require a force to pull it out of the tube. The force is of the order of 50% of the ultimate tensile strength of the strip and tends to resist the spread of a crack extending transversely of the tube. The longer the crack becomes the more strips come into effect and apply resisting forces to the crack. The strips have a cross-sectional area of about 3% of the cross-sectional area of the whole structure. The strips may alternatively be of zig-zag form or a combination of zig-zag and sinusoidal form. The tubes have integral frames (21), Fig. 1 (not shown).

Title: Improvements in apparatus for indicating the power output of an internal combustion engine
IPC: G01L3/24
Filed: 1935-02-19
Abstract: 454,093. Engine indicators; speedometers. BENDIX AVIATION CORPORATION, 105, West Adams Street. Chicago, U.S.A. Feb. 19, 1935, No. 5330. Convention date, Feb. 20, 1934. [Class 106 (ii)] An instrument for indicating the power output of an internal-combustion engine comprises means responsive to the engine speed and means responsive to the pressure in the engine intake and a switch is included to make the instrument read engine speed only. The aircraft engine 3 drives a propeller 4 the pitch of which is automatically varied with the load, and is provided with a supercharger 5. The engine also drives a twophase alternating-current generator 2 supplying a.circuit 8, 9, 10 in which is an alternating- current indicator 11. The reading of this will remain constant when the speed of the engine is maintained constant by the variable pitch propeller. As the aircraft climbs to a higher altitude the power of the engine will fall off due to rarefaction of the air although the revolutions of the engine are kept constant. An inductance coil 12 is connected in series in the common lead 9 of the two-phase circuit. A barometric device 14 is connected to a sector 16 carrying the coil 12 and moves the latter towards the core 13 and increases the impedance of the coil thus causing an indication of decreased horse-power due to the rarefaction of the air. The pilot is thus warned to supercharge the engine or increase the throttle. The interior of a diaphragm device 19 is connected by a pipe 21 with the intake manifold 20. Movement of the diaphragm is transmitted through the rod 23 to the core which is mounted on a, pivot 18. This moves the core 13 awav from the coil decreasing its impedance and increasing the potential difference between the generator and the instrument 11 which indicates increased horse power. In a modification a direct current generator is used, the quadrant being moved by the diaphragm 19 and carrying a rheostat over which moves an arm connected to the device 14. In addition to or in lieu of the barometric control a temperature control comprising a resistance 34 is incorporated. If worked by the temperature of the engine, the resistance 34 should be of material the resistance of which decreases with increased temperature, and if worked by the temperature of the air, then its resistance should increase with increase of temperature. The indicator 11 may be provided with two scales and a switch 35 fitted to cut out the circuit of the coil 12 or of the corresponding resistance in the modification, so that one scale of the indicator engine speed may be read with the circuits cut out or on the other scale horsepower may be read with the circuits functioning.
