Title: Twin cylinder type concrete pump - has seal on swivel pipe hydraulically loaded by pressure in pipe through flexible membrane
Inventor: GESCHKE HANS-JOERG
IPC: F04B7/00
Filed: 1979-05-29
Abstract: The pump has a swivel pipe which oscillates between the ends of two cylinders. Its face runs across the endplate (1) of the cylinders. An intermediate ring (7) is bolted to the end of the swivel pipe. It has an annular groove (9) in which a sealing strip (4) is pressed against the cylinder endplate. The strip is pressed out by the hydraulic pressure of a liquid in an annular chamber (10) behind the groove. A flexible membrane (11) separates the chamber (10) from the inside of the swivel pipe and transmits the pressure in the pipe to the chamber. A separate reservoir (13) maintains the liquid volume in the chamber.

Title: Pressurised water filter - with small bore opened in absence of filter element removed for cleaning
Inventor: ECKER FELIX
IPC: B01D29/46
Filed: 1979-05-30
Abstract: A filter for insertion in a pressurised water system, specially for hydraulic properties to support the roof strata in mines, inludes a filter element consisting of a stack of annular laminae, leaving a system of parallel slots. The preferred flow direction is radially inward. A small bore through the housing at an abutment of the element is normally sealed by two O-rings. If the personnel is too lazy to clean a clogged filter element, and throws it away, a jet of water leaves through the bore. This enforces the use of a clean filter and saves the ruin of expensive hydraulic equipment.

Title: Large scale liquid level - has two vertical communicating tubes with electrode bridging detector
Inventor: IRLE HERMANN
IPC: G01C5/04
Filed: 1979-06-18
Abstract: The large-scale spirit level has two vertically positioned transparent tubes contg. water and joined together by a tube between the lower ends. It requires only a single operator and enables rapid, reliable, relatively economical measurement within narrow tolerances. One tube (1) contains two or more electrodes (6,7) and an associated signal unit producing visual and/or electrical indication when the electrodes are bridged by the water. A marker (11) connected to the tube or housing shows the level at which the signal is triggered. The difference in height of the two electrodes corresponds to the narrow measurement tolerance. It is applicable in the construction industry, for example, where equal height points inside a building are to be determined, e.g. for accurate maintenance of floor covering levels.

Title: O=rings, large dia. profiled seals, and wipers - produced in small moulds eliminating piecing together of ends
IPC: B29D99/00
Filed: 1979-07-26
Abstract: Nesting mould in the form of a semicircle has, projecting at the points where the circle is divided, supports continuing the profile of the moulding cavity. These have at their ends zones of good isolating material or zones which can act as cooling zones. Parallel to the actual moulding cavity, overflow grooves are provided for excess raw material when the mould is closed, and the arrangement makes it possible to produce "O"-rings and profiled seals of very much larger diameter, than that of the press mould used. At the same time, the extra work normally required for glueing together or jointing by vulcanising, which is always accompanied by the risk of an unreliable joint, are eliminated.

Title: Ancillary device for an answering machine and fax machine
Inventor: KUHNLE KLAUS
IPC: H04N1/327
Filed: 1981-02-23
Abstract: The invention relates to an ancillary device for telephone systems with an answering machine and fax machine. Through the invention, the disadvantage of current telephone systems of this type is eliminated in that, when the receiver system is not manned, the fax transmission process must be initiated without previously being able to ensure by means of a preceding telephone link that the required receiver has actually been dialled. If the answering machine has answered, it disconnects the telephone link at the end of the announcement and the fax machine must be redialled. The object of the invention is to ensure by means of a simple ancillary device that, despite the establishment of the speech link by the answering machine, the fax link can be set up without interrupting the telephone call. This object is achieved according to the invention by assigning a signal transmitter (3) to the answering machine (1) which, before disconnecting the speech link, transmits a control pulse to the fax machine (2) in order to activate the latter and set up the fax transmission link. The ancillary device according to the invention can either be built into the answering machine or designed as an independent "piggy-back" unit which can subsequently be connected to any answering machine. <IMAGE>
