Abstract: A means for measuring milk drawn with a pipe milking machine, particularly in systems according to the Patent F1 65697, in which the milk is pumped from a centrepiece (2) by a vacuum pipe (4) with the aid of a pump (6) into a milk pipe (12) under normal pressure. The pump of said Patent operates under control by the pulsator of the milking machine. Hence follows that the piston strokes are different in length, and therefore their number does not give the exact milk quantity. As taught by the present invention, the operation of the pump takes place under control by vacuum so that the extreme positions of the pump's piston control a control valve (24, 24'). The control valve admits the vacuum alternatingly on either side (8, 10) of the upper part of the pump piston (7). The piston stroke length thus obtained is accurate enough, whereby the piston stroke with the aid of the readings of a counter (25) yields an accurate enough milk quantity measuring result. The means also enables a sample quantity of desired magnitude to be taken.

Inventor: JUDD WENDELL
IPC: D21D1/00
Filed: 1990-07-13
Granted: 1996-06-18
Abstract: This invention provides a method and apparatus for recycling paper pulp sludge. Paper pulp sludge is incinerated in a rotary kiln, typically a rotary cement kiln, asphalt dryer, or fluidized bed incinerator. Paper pulp sludge is fed continuously into said rotary kiln while temperatures are maintained in the range of approximately 800° to 3500°F. During incineration, mixing catalysts (typically casein or soy protein) and wood pulp fibers are burned, while moisture is evaporated. The resulting incinerated product consists essentially of carbonate particles which are collected for subsequent use. Typically, but not exclusively, later use of the resulting product could be as mineral filler binding agents in the manufacture of construction products such as concrete, asphalt and others; or in gravel-based construction operations; or in earthen-fill constructions operations; or in other ways.

Title: Disposable syringe and injector
Inventor: LINDMAYER ISTVAN
IPC: A61M5/30
Filed: 1990-07-19
Granted: 2002-02-05
Abstract: In general, syringes for needleless injectors must be reasonably accurately dimensioned, and the barrel of the injector must be formed of metal in order to prevent expansion of the syringe under pressure. A simple alternative is a syringe including an elongated tubular body with one open end and a closed end containing an injection orifice, and a plug slidable in the body with a prong at one end of the plug extending. towards the orifice end of the body, the prong carrying an O-ring and an annular seal which prevents squeezing of the O-ring between the body of the syringe and the plug under injection pressures. An alternative form of syringe includes a pair of valves, one of which normally closes the injection orifice, and the other of which is mounted on the plug. The orifice valve opens under injection pressure to permit the passage of medicine from the syringe body through the orifice, and the other valve opens when the plug, which contains a longitudinally extending passage, is moved away from the orifice end of the syringe body. With such syringes, the body of the injector can be manufactured from plastic, as can the barrel for receiving the syringe.      Moreover parts no longer need to be particularly accurately dimensioned.
