Abstract: 971,468. Electronic calculating apparatus. BELL PUNCH CO. Ltd. April 30, 1962 [May 1, 1961], No. 15669/61. Heading G4A. The keyboard-controlled calculating machine described in Specification 925,161 is modified in its means for propagating carries and interdenominal shifting in that a bistable carry circuit CS is provided which during an addition is set by a pulse on line C from any counting stage 1R-13R counted up to 0, and reset at the next PO time (in the next cycle) to produce a pulse which is transmitted over line L to the next denomination. Circuit CS also acts in a manner similar to that of the circuit designated CS in Specification 925,161 during a shift operation to gate sets of 10 pulses each to one of the counting stages until it reaches 0, when CS is switched to gate the remainder to the next higher stage. The counting stages may be of the type described in Specification 925,308.

[Classes 83 (ii) and 83 (iv)] Jointing by stamping and spinning.-In a method of making a hollow metal door knob the parts are electroplated after making a fluid-tight assembly so that the electrolyte does not reach the internal surfaces and cause subsequent corrosion. The outer cast or pressed part A has its flange f spun or pressed over the rib b on the cast or moulded part B to form a fluid-tight joint. The part B has a thin diaphragm E closing the usual hole D in the shank and completely sealing the knob. After electroplating the diaphragm E is sheared away by the normal square shank or by a tool. Relative rotation of the two parts A and B may be prevented by forming a projection G on the part B which engages a slot f<SP>1</SP> in part A.

Abstract: 945,495. Reciprocating pumps. STEWART-WARNER CORPORATION. May 6, 1960 [May 8, 1959], No. 16091/60. Heading FIA. A manually operated pump for delivering liquid from a source to a supply line includes a pressure-actuated latch preventing further pumping when the delivery pressure exceeds a predetermined value. The operating lever 8 is inserted in a U-shaped bracket 9, rotatably mounted on an arm 27a formed integral with the housing 10. Also mounted on the housing 10 is a latch release lever 15, latch 16 and latch return spring 18 the latch 16 having a detent portion 16a for gripping a pin 14 and preventing operation of the pump, Fig. 3. When the piston 42 is retracted it uncovers inlet ports 48 in the cylinder 40 and during the pumping stroke of the piston, liquid is forced past the ball check valve 46 and through radial ports 45, aperture 49, port 30, aperture 54 and a strainer to the outlet. A vertical aperture 55 provided in cylinder 50 is also connected to the outlet and serves as a vent port. The plunger 60 has two annular grooves 61, 62 and a spring loaded ball rests in the groove 61, when the pump handle 8 is latched Fig. 3 To permit operation of the pump, the lever 15 is rotated about the pin 17, the lower end 15a bears against the plunger 60 moving it into the housing 10, the ball is forced into groove 62, the collar 26 also moves to rotate the latch element about the pin 17, this disengages it from the pin 14. As piston 52 is moved by plunger 60 it covers the vent port 55 to disconnect it from the outlet. When the liquid pressure reaches a predetermined value determined by adjustment of the spring loading of the ball, piston 52 and plunger 60 are forced back and the ball is forced into the groove 61 and the vent port 55 is uncovered.

Abstract: 236,215. Fichter, M. R. June 24, 1924, [Convention date]. Induction m o t o r meters.-In order to compensate for the increased braking effect, the magnetic flux of the series magnet is deflected towards the periphery of the driving-disc at high loads so as to increase the torque. The polepieces 9, 10, Fig. 2, of the series magnet 8 are formed with projections 9<1>, 10<1> of reduced crosssection so as to become saturated at a certain load. Two soft - iron pieces provided with similar projections 11<1>, 12<1> are placed near the poles 9, 10 and further from the axis 2 of the disc 1. As the projections 9<1>, 10<1> become saturated, a greater proportion of the lines of force passes from the pole-pieces 9,10 to the projections 11<1>, 12<1>, thereby causing the magnetic field to act on the disc 1 at a greater radius. The shunt magnet 5 has a core formed of stampings of the shape shown in Fig. 1, without joints, the part 4<11> being temporarily bent aside to allow the coil 3 to be slipped on.

Class 135 In a spring-loaded relief valve having manually operable means to adjust the loading of the spring to two independent working settings, the means are located exterior of the valve casing to enable the settings to be changed without dismantling the valve. As used with under-water breathing apparatus, the valve comprises a twopart casing 2, 4, Fig. 1, clamping between its parts a breathing bag 1, and housing a valve closure member 24 loaded by a spring 29. The upper end of the spring abuts an operating member 20 having a pin 30 engageable in an L-shaped slot 31, Fig. 3, formed in a sleeve 16 screwed to the casing. The loading of the spring is initially adjusted by the sleeve 16 which is then locked in position by a nut 17. When the pin 30 engages the top of the vertical limb of the slot 31 the valve is adjusted to its lower working setting and air is automatically permitted to escape whilst the wearer of the apparatus ascends to the surface. On reaching the surface the wearer depresses and rotates the member 20 to bring the pin 30 into engagement with the horizontal limb of the slot 31 to set the valve at its higher setting. At this higher setting further escape of air is prevented, except under abnormal conditions, and the bag 1 keeps the wearer afloat.

Title: Improvements in a method of dehydrating yeast
IPC: C12N1/04
Filed: 1937-06-12
Abstract: A method of drying yeast after its separation from the wort consists in adding water-soluble substances to the yeast, mixing them with the yeast, and immediately afterwards separating the newly-formed solution from the yeast without any fermentation taking place.  The substances are preferably such as are used for the subsequent production of new quantities of yeast. Concentrated sugar products, or nutritive concentrated salts may be added separately, or in combination, to the yeast.  If 100 kilograms of yeast containing 74 per cent water are mixed with 50 kilograms of sugar syrup containing 45 per cent water, a residue, after filtration, is obtained which contains 26 kilograms of yeast and 20 kilograms of water.  When 100 kilograms of yeast, 15 kilograms of sugar and 1 kilogram of primary sodium phosphate are mixed, about 45 kilograms of solution are withdrawn by filtration.
