Title: Printing pure wool or cotton fabrics with transfer webs - at room temp., by treating fabrics with liq. plastics soln. to form flexible film on surface
Inventor: MANIURA REINHOLD
IPC: D06P5/28
Filed: 1977-10-25

Title: Metal plate joining system - using enamel coatings fused to joint by firing
Inventor: EDER-MILCHGIESSER WALDBURG DR
IPC: F24S10/50
Filed: 1978-01-03
Abstract: Metal plates to be joined to each other, e.g. to produce absorber plates with parallel passages for solar heat collectors, are first given an enamel coating, at least along the areas where they are to be joined. After the enamel layer has been applied, they are fired and joined together. This produces a durable and tight joint, without the added susceptibility to corrosion of welded joints or the risk of leakage after long-term exposure to temperature fluctuations like bonded joints.
Patent DE-2808873-A1 (DE)
Inventor: EHLER MARTIN
IPC: G10D9/02
Filed: 1978-03-02
Abstract: Slot-shaped windows (6, 7) are formed by longitudinal and transverse strips (2, 3 and 4, 5, respectively) in the carrier plate (1). Located above each window is a tuning reed (8) which has a section (11) fastened to a transverse strip (5) and a section (10) which can vibrate at the free end in the window (6, 7) between longitudinal strips (2, 3). Mass production can be simplified while retaining at least the previous quality if the tuning reed (8) in the two sections (10 and 11) and a groove (14) in the transverse strip (5) have at least approximately the same width, and the base line (19) of the longitudinal section of the groove (14) is lowered downwards starting from the window-side edge by an angle relative to the carrier plate (1) in such a way that the tuning reed (8) projects (22) at the free end. Further improvements are achieved by an expanded boot-shaped attachment (25) and an additional strip (32) whose thickness is reduced, possibly as a groove (33), over the entire extent of the carrier plate at a right angle to the longitudinal direction of the tuning reed. The carrier plate (1) fitted with the tuning reeds (8) is intended for use in tone air slots in a harmonium, a mouth organ, accordion or the like. <IMAGE>

Title: Automotive engine waste heat utilisation - uses absorption refrigeration process to aid engine cooling
Inventor: KALWAR KLAUS
IPC: B60H1/32
Filed: 1978-05-30
Abstract: The process uses the waste heat from a fuel-burning automotive engine. This heat is used to give a refrigerating action by the absorption process and thus partly to cool the engine. The remainder of the cold generated can be used to cool the engine compartment, and also the passenger space. The boiler (6) for the absorber can be mounted in the waste heat discharge pipe (5), and connected by feed and return pipes to a vapouriser (9). Conduits from the above (13, 14) lead to the engine compartment and passenger space.

Title: Flocked yarn electrode cleaning - using continuous belting to remove clinging flocks for suction extraction
IPC: B05D1/14
Filed: 1978-09-14
Abstract: In the electrostatic unit for the manufacture of flocked yarn, there is a carrier for the flocking removal unit under the upper electrode to remove flock material clinging to it. The carrier is a continuous belting passing round deflector and drive rollers to travel round the upper electrode and cladding. It carries material past the suction tubes to remove unwanted flocking. The conveyor belting is composed of glass fibre material, and the deflector and drive rollers are made of a material which is not electrically conductive, or they are clad with an insulating material. The system prevents flock material clinging to the electrode, so that there is no efect on the electrostatic field by the presence of matter around it.
