Title: Multilayer casing for producing rectangular packaging containers - uses individual webs of paper, fabric and plastic of different width along casing
Inventor: KIRCHBERG KARL
IPC: B31B105/00
Filed: 1977-02-18
Abstract: Multi-layer casing is designed for manufacturing packaging containers esp. of rectangular cross-section and employs individual webs (2a, 2b, 2c) of paper, fabric, plastic, and film which are of different width in the longitudinal direction of the casing. The outermost layer (2d) comprises a label web which overlaps the casing.

Title: Table top skittle alley - has pivoted ramp to accelerate and direct balls towards skittles, and return tube for balls
IPC: A63D3/00
Filed: 1977-03-19
Abstract: A table skittle alley consists of a rectangular box (11) with its upper surface (13) forming the track for the balls.

Patent DE-2722519-A1 (DE)
Inventor: SAUFHAUS EGON
IPC: G05D11/13
Filed: 1977-05-18
Abstract: Each component of the binding agent is passed to a mixing vessel (19) via a discharge pump (13, 14, 15). The discharge pumps (13, 14, 15) are connected to a drive motor (43), which is regulated according to a guide setting representing the requirement for binding agent. The delivery rate of one discharge pump (13) can be corrected by means of a speed control device (42) downstream of the drive motor (43), and the delivery rate of each further discharge pump (14, 15) can be corrected by means of a correction member (50, 52; 51, 53) downstream of it on the drive side. The corrections are made by comparisons between actual values and desired values. The desired values can be set using a quantity setter (41) or desired value setters (66, 76) and applied to in each case one comparator (57, 68, 78). For correction purposes, the individual components are drawn off through the discharge pumps (13, 14, 15) one after the other from storage containers (2, 3, 4) of a weighing container (1), with weighing being carried out. Upon discharge, a load cell (5) delivers the respective actual value signal to the relevant comparator (57, 68, 78) via a measuring transducer (58) and a selector switch (60, 69). By means of appropriately adjusted three-way valves (10, 11, 12), during weighing of one component the other components are passed to the mixing vessel (19) by means of the discharge pumps via direct lines (30, 31, 32). This weight-based controlled delivery guarantees an at all times constant mixture ratio of the binding agent. <IMAGE>

Title: Deep drawing tool for synthetic film packaging containers - prevents uneven stretching and weak places at bottom corners
Inventor: VETTER ARTHUR
IPC: B29C51/00
Filed: 1977-06-02
Abstract: Synthetic films are deformed by raising their temp. to a point below that at which they deform, and drawing them into a heated mould. The deformed, heated film is then placed in a cold mould. The heated mould is smaller than the dimensions required for the finished moulded prod. The cold mould has the final desired shape and the heated, deformed film is drawn into the cold mould. The drawing of the film is effected by vacuum. The film is pref. at a temp. below that at which it deforms and the surfaces around the mould cavity which come into contact with the film are heated. Method overcomes the shortcomings of existing machines in which the corners and edges of the mouldings are stretched more intensively than the rest. Weak places are thus avoided. The containers have a uniform thickness, and the total strength of the film can be reduced, since its temp. is held below deformation point until it comes into contact with the mould cavity wall.

Title: Applied stress measuring appts. - has intermediate frame to prestress compressive force transducers
Inventor: BISCHOFF BRUENE ING GRAD
IPC: G01L1/26
Filed: 1977-07-02
Abstract: Two pressure transducer (1, 2) are pressed against a plate (3) which forms part of a suspension (4). A force input member (5) applies an alternating stress to the two pressure transducers by way of the intervening suspension and plate. The two pressure transducers (1, 2) are prestressed by means of a crossbeam (6) and base plate between which they are clamped by screw bolts (8). As an alternative, to the illustrated arrangement, which shows an input member (5) for compressive forces, the rod may be bolted to the suspension plate to permit input of tensile forces as well. In a further embodiment, the principle is applied to a rotary apparatus to permit the measurement of torsional stress.

Patent DE-2820248-A1 (DE)
Title: Thermodynamic process and latent heat engine - forming closed cycle system in which fluid exhausted from turbine and condensate is recompressed
Inventor: CZAJA JULIUS
IPC: F02C1/00
Filed: 1978-05-09
Abstract: The process produces gaseous fluid jets by using primarily the latent heat of condensation for the energy required. Water vapour is mixed with a gaseous fluid such as air, and the mixture is expanded in a nozzle sufficiently to condense a portion of the vapour and transform the latent heat of the condensation into kinetic energy of the gaseous fluid. The process can be used to form a gaseous fluid jet, which can be used to drive the turbine of a heat engine for either open-cycle or closed-cycle operation. Moist ambient wind can be used as the energy source for producing a jet that drives a wind turbine, or a boiler can be used to form saturated vapour mixed with the gaseous fluid and directed into the nozzle. For closed-cycle systems, the gaseous fluid exhausted from the turbine and the liquid from the condensation of the vapour are both recompressed the liquid is revaporized, and the vapour and compressed gaseous fluid are recombined.

Title: Simplified editing of sound cine film - with editing markings applied to film before cutting for retrieval of sound
Inventor: MUETING BERND
IPC: G03B31/02
Filed: 1978-05-05
Abstract: The simplified sound cine editing process uses special markings applied to the start of each scene before editing. The selected sequence of scenes is t hen pr ogrammed into the control and the film passed through the equipment. The sound tracks are taken off the original in the new selected sequence, with automatic forward and reverse drive between scenes. The new sound track is then applied to the edited film after cutting. The new edited film has signals between the new scenes so that the sound track can be accurately married to the film. This is either by re-recording on the sound track or by linking the film to a tape recorder with the edited sound track.

Title: Bulk goods loosening process used in silos - uses balanced airflow introduced from below to facilitate pouring and storage of flour
IPC: B65D88/72
Filed: 1978-10-02
Abstract: The system is used for conveying goods in powder form from silos. It is used esp. for bulk goods with poor pouring characteristics and to improve the storage for goods such as flour which has only limited storage capability. The bulk goods stored in the silo are loosened by air pressure introduced from below and supplied at set intervals.
