Title: Improvements in or relating to metering tanks
IPC: B28C7/12
Filed: 1952-01-26
Abstract: 714,725. Delivering measured quantities of liquids. LINER CONCRETE MACHINERY CO., Ltd., and SKELTON, J. L. Jan. 21, 1953 [Jan. 26, 1952], No. 2208/52. Class 106(5) [Also in Group XXIX] A metering tank, particularly for delivering measured quantities of water for concrete mixing has a spring-loaded leveroperated discharge valve 13 fitted in the dished bottom of the tank and a float 3 adjustably mounted on a rod 2 operating an inlet valve 19 and is provided with a locking plate 8 which maintains the rod 2 in the raised position during emptying of the tank so that total measured volume may be delivered in instalments by intermittent operation of the discharge valve, without additional water entering through the inlet valve. The plate 8 is loosely fulcrummed in a slot 9a in a bracket 9 and has a hole which is a clearance fit on the valve rod so that the plate tends to drop slightly and cause the edges of the hole in it to grip the rod. When the tank is empty, the plate may be raised by a release lever 10 to free the rod in the hole and allow the rod and float to fall, thus opening the inlet valve. The valve rod fits at its lower end in a bore in the discharge valve and is raised by the discharge valve so that the resilient face of the inlet valve is pressed against its seating with a pressure slightly above that necessary for effective sealing, to compensate for the slight drop of the valve rod before it is fully locked by the locking plate. For adjusting the float, the screw-threaded valve rod 2 is rotated by a spindle 5 connected to it by a chain drive and the float is constrained against rotation by a rod 4. The float may be open at its lower end as described in Specification 714,724.

Title: Animal feedstuffs
Inventor: BURT ALEC WILLIAM ARTHUR
IPC: A63C11/06
Filed: 1963-01-18
Abstract: An additive for an animal feedstuff comprises dried invertase-containing micro-organisms, particularly yeast, having an invertase activity of at least 10.  (The invertase activity is the number of grams of sucrose which would be hydrolysed by 1 gram of the dry yeast when incubated with sucrose in acetic acid buffer of pH 4.5 at 37  DEG C. for 2 hours). Other invertase-containing micro-organisms such as Aspergillus and Penicillium spp. may be employed.  The dried additive may form from 0.05-5% by weight of the dry feedstuff. When included with sucrose, the dried additive and the sucrose may form from 0.01-3% and from 10-30%, respectively, by weight of the dry feedstuff, the dried additive being present in an amount sufficient to hydrolyse all but a small amount (say 5%) of the sucrose.  According to an example, a yeast slurry of 15% solids content was spray-dried to a moisture content of 5.6% in an apparatus providing an inlet temperature of 170  DEG C., an outlet temperature of 85  DEG C. and an average residence time at 85-90  DEG C. of 1 1/2 minutes.  The invertase activity of the spray-dried yeast was 500, as compared with 650 for the fresh yeast.

Title: Household cooking apparatus
IPC: F24C15/10
Filed: 1975-01-21
Abstract: 1478583 Electric hot plate ETABS EUGENE SCHOLTES 21 Jan 1975 [23 Jan 1974] 2559/75 Heading H5H To prevent overheating of the glass-ceramic hot plate 1 in the area surrounding the thermostatically controlled heating resistance 6, an additional temperature sensor 19 surrounding the resistance 6 is connected to a control device (not shown) to de-energize the heating resistance should the temperature of the surrounding area become excessive. The heating resistance 6 is a spiral metal sheathed element with a flattened upper surface mounted by spaced supports 8 in an annular reflective trough 7 which cooperates with glass-ceramic hot plate 1 to form a sealed chamber. A casing 9, 10, 12 made of thermal insulation is spaced from an external housing 3 by distance pieces 11. The reflector 7 is centred in an aperture of the upper wall 9 of casing 9, 10, 12. A metal bulb type sensor 15 of an adjustable thermostiatc switch is in direct contact with the centre of the heating zone to control cooking temperature. The additional temperature sensor 19 is in the form of a tube filled with an expansible liquid or in the form of a temperature sensitive resistor. Sensor 19 prevents overheating of the surrounding area due to inaccurate centring of a cooking vessel on the cooking zone, the use of too small a cooking vessel, the use of a vessel with a convex bottom, or the user forgetting to switch off the hot plate. The cut-out temperature of the sensor 19 may be fixed or it may be adjustable with the thermostat. If it is adjustable with the thermostat it is arranged always to cause cut-off at a higher temperature than the regulating temperature of the thermostat. In an alternative construction the flat upper surface of the resistance 6 engages the glass-ceramic hot plate 1 but the spaced supports 8 are mounted on a reflecting screen spaced from the bottom of a easing by a corrugated metal screen. The hot plate may be built into a conventional cooker or into work tops of kitchen furniture.
