Title: Thermoplastic container filling and packing system - delivers prod. into extruded hose formed into chain of packings
Inventor: MORONI ROLF
IPC: B29C48/13
Filed: 1976-11-27
Abstract: The system fills and packs products in plastic containers, partic. rigid ones, and is espec for lavatory pan cleaning devices comprising soap-type masses in open plastic vessels. The material is delivered into an extruded plastic hose (12), which is then formed by shaping tools (16, 17) into a chain of successive packings. The hose can be caused to expand into the tools by the introduction of the product aided by a vacuum applied to its outside via the tools. The hose can be perforated by punches to form wall openings, and the contents can be delivered via an internal passage (13) in the extrusion spray head (11) and under pressure. They can also be heated for this operation.

Title: Cooker control system with switching panel - has sensors with additional switch preventing further inputs
Inventor: ANDERS KLAUS DIPL ING
IPC: H03K17/945
Filed: 1977-05-24
Abstract: The sensor switching panel, is designed for use in domestic equipment such as cookers. The design ensures that a wanted setting is not inadvertently erased or altered. An additional sensor switch is provided that prevents further inputs being made via the main sensor switches and is located along one edge of the panel or all around the panel or around individual sensor switches. This ensures that e.g. any child interfering with the controls will inevitably touch the outer blocking sensor first and thereby disable the actual control sensor or sensors.

Title: Space heating appliance with room ventilation - has containers to allow fresh air in and exhaust air out to atmos.
Inventor: ESER ANSELM
IPC: F24D5/02
Filed: 1977-06-20
Abstract: The heater or radiator has fresh air supply- and exhaust air outlet containers, which are fastened to it on either side so that the air they contain is heated when the radiator itself is heated. This causes the air in the containers to rise. A connection pipe and a control valve allows fresh air to pass into the corresponding container from outside the living room to be heated. The heated air rises and flows through an upper aperture into the room. The exhaust air container has a lower inlet, to allow exhaust air to pass into it from the room. The heated air passes through the pipe and a control valve to atmos.

Patent DE-2732476-A1 (DE)
Inventor: WILKESMANN HELMUT DR ING
IPC: B04B11/08
Filed: 1977-07-19
Abstract: Two pivotable scraping-out elements (25, 26) are arranged in such a way that when they are pivoted firstly the first scraping-out element (25) engages and, during further pivoting the first scraping-out element disengages and the second scraping-out element (26) is in engagement. In this way, the scraping-out capacity is improved on the basis of the fact that the individual scraping-out element only has a limited scraping-out angular range with optimum scraping-out conditions. The scraping-out device is suitable for scraping-out centrifuges for discharging the solid cake and for scooping out annular collections of fluid, for example in centrifuges. <IMAGE>

Title: Chuck with spring segments locked by coned nut - has limited rotational travel of inner sleeve for easy release of tool
Inventor: SIDDALL KEITH
IPC: B23B31/20
Filed: 1977-09-28
Abstract: The chuck (10) has a bore (12) to receive a sleeve which has a number of longitudinal slots (24). The sleeve (22) has an internal thread (26) to match the screwed end of the tool which abuts against the point (14) of the stop (18). The tool is then clamped by the nut (36) which has an internal conical surface (40) which presses on the end (34) of the sleeve (22). To make it easier to remove the tool after use, the sleeve (22) has two diametrically opposite lugs which allow the sleeve a limited degree of rotation between the screwed stops (30). This motion removes the pressure between sleeve (22) and nut (36) so that the nut can be unscrewed from the body.

Title: Tunnel lining concrete pump - has telescopic delivery tube with multiple section sealing arrangement at sliding joint region
IPC: E21D11/10
Filed: 1977-10-01
Abstract: The system for depositing wet concrete behind a tunnel lining, in mining and tunnelling operations, uses equipment which includes a concrete pump which forces the concrete along a line to a telescopic tube (28, 29). The delivery end of this tube then fits inside a connecting sleeve (4) attaching to the tunnel lining. The region of the sliding joint between the two tubes incorporates a sealing arrangement which prevents the cement from being forced ino the joint. The inner tube (29) carries annular strip guides (33, 37) between which locate two sealing rings (43, 44) with a gap between. These are retained by braking rings (32, 47) which fit into grooves in the inner pipe. An intermediate sleeve (34) fits between the sealing rings and the outer tube (28), and an intermediate seal (45) fits between the innermost locking ring (47) and the innermost annular strip guide (37).
