Abstract: 753,044. Gear pumps. HOBOURNEATON MANUFACTURING CO., Ltd. March 12, 1954 [July 15, 1953], No. 7237/54. Class 110(2) A gear pump as described in Specification 751,788, in which the pump pocket 26 has an end plate 18, has a limited area subjected to the discharge pressure to keep it against the rotors without tending to distort it. A cover plate 20 contains the inlets and outlet ports which are imaged by recesses 70, 72, respectively, in the end plate 18. A ring gasket 62 is squashed between the end plate 18 and the housing 22 in an annular groove 64, eccentric to the shaft 36. A hollow split pin 30 is located in a hole 32 in the end plate and in a socket 34 in the housing 22 preventing rotation of but allowing axial movement of the end plate in the pump pocket 26 and allowing fluid under pressure to act on the surface 61 outside the ring 62 influencing the plate 18 against the rotors and the sleeve 40. In a modification the end plate 102 has an eccentric circular boss 122 in which is formed the inlet port 118, and a recess 138 formed in the face 132 which is an image of the discharge port in the cover plate 106. A ring gasket 126 fits over the boss 122 and is squeezed between the casing 104 and the end plate 102 which is held by a pin (not shown) located in a hole 134, as before, allowing fluid under pressure to act on the surface 120 outside the ring 126, while the intake fluid acts on the surface of the boss 122 inside the ring 126.

Title: Machine Guard Element
IPC: F16P1/00
Filed: 1980-08-11
Abstract: A machine guard element of a mounting part 10 pivotally supporting a guard of plate from 20 in a forked arm 12, 14.

Title: Control apparatus
IPC: F24D19/10
Filed: 1980-09-01
Abstract: A control system for a boiler (1) in a domestic hot water and/or central heating system and having a thermostat and an electrically operable valve (both not shown) controlling fuel supply to the boiler comprises a parallel connection of a switch (40c or 50c) and a high impedance (31) provided in the valve supply circuit so that when the switch is open, the valve will not operate even if the boiler thermostat closes to turn the boiler on. Thus unnecessary cycling of the boiler is eliminated and the boiler can be made to fire only in dependence on a thermostat in the water tank and/or a room thermostat. The switch (50c) is operated by a relay (50) controlled by a room thermostat (10), while the switch (40c) is similarly controlled by one of two water tank thermostats (8, 9) at different heights in the tank. The high impedance (31) is a lamp which, when lit, indicates that the boiler would be ON if it were not for the present system. <IMAGE>
