Title: Extended colour photoelectric emulsion - has additional semiconductor layer to absorb longer wavelengths and add to signal from main layer
Inventor: DORND REIMUND DR RER NAT
IPC: G03G5/082
Filed: 1980-08-07
Abstract: An extended range photoelectric emulsion has an additional semiconductor layer (3) between the base layer (2) and the main emulsion (4). The additional layer absorbs longer wavelengths and compensates for the reducing red sensitivity, with increasing wavelength, of the conventional photoelectric layer (4). The additional layer has a high dark current resistance and is one of a number of materials including lead oxide, lead sulphide, silicon or germanium. The emulsion can be used for colour copying, with three successive colour prints. For electrophotographic writing the emulsion is exposed by an array of LEDs.

Patent DE-3041749-A1 (DE)
Title: Blow moulding hollow plastics floats - after stiffening ribs formed by local inward indentations produced by air jets
Inventor: DREXLER ERNST ANTON
IPC: B29C65/02
Filed: 1980-11-05
Abstract: The parent patent describes a method of making hollow plastics objects, esp. floats, by blow moulding a plastics tube inside a mould before the blowing stage commences, certain parts of the tube are pressed inwards from opposite sides into mutual contact, are sealed at these points or lines, and thus stiffening ribs or wall zones are produced, which remain as stiffeners in the final blow moulded object. In the patent of addition, these inwardly distorted zones are produced by compressed air jets acting from the outside onto the surface of the plastics tube to produce the deformed zones, which are then sealed together. The process of the parent patent is still further simplified by the use of air jets instead of mechanical slider devices.

Title: Method for the allocation of locked-out direct-dial connections transferred to the operator's position of a telephone PABX system under specific conditions
Inventor: GOEBEL THOMAS DIPL ING
IPC: H04Q3/62
Filed: 1981-01-26
Abstract: By means of the method for allocation of locked-out direct-dial connections transferred to the operator's position of a telephone PABX system under specific conditions, a connection of this type can be allocated to the extension subscriber in simple fashion. For this purpose, all that is required is to press a special key or to use the existing last number redial key. To achieve this, the telephone number of the extension subscriber which the calling external subscriber had dialled is retained in the memory area of the main memory assigned to the allocated direct-dial exchange line. This telephone number is furthermore displayed together with the condition which had led to the lock-out on the display panel of the operator's position. The operator is thereby informed in optimum fashion of the events relating to the connection.

Title: Automatic and continuous machine for the production of dried bean curd
Inventor: LEU CHUAN-CHUNG
IPC: A23P30/10
Filed: 1982-07-17
Abstract: The machine is composed of the following devices connected one after the other: a dividing and filling device (1), which fills flat baskets with the same quantities of soft bean curd, conveying means (2), by means of which the baskets are successively brought to a lifting table (3). The baskets are then passed to a hydraulic moulding unit (4), which is composed of a relatively large number of moulding machines (5) having a hydraulically driven press plate (8). Pressing to dewater the basket contents is carried out over predetermined times and can be controlled by a microprocessor. After moulding, the dewatered bean curd is removed from the baskets, sliced in a slicing machine (17) and fed via a conveying apparatus (18) to a machine (20) for cooking the bean curd in alkaline solution. After leaving this machine, the bean curd is cooled in a cold air drier (30) and dried, then fed to a machine (33) to be pigmented and marinated and is finally dried in a further cold air drier. The moulding machines (5) can be operated so that pressure is exerted on the baskets in a stepwise manner. <IMAGE>

Title: Method and arrangement for double-sided and/or translucent viewing of the workpiece during a sewing operation or similar operations in sewing machines or similar machines
Inventor: NEUSEL OLGA
IPC: D05B79/00
Filed: 1983-01-15
Abstract: The invention improves the work safety and reduces the tiredness and endangering of a worker by facilitating and rendering more precise the required positioning of materials which are joined or equipped by machine through sewing or similar operations performed in steps. The technical instructions that can be realised are described in principle as follows: the positioning is visualised from both sides of the workpiece directly in front of and directly at the site of processing, in the simplest case by means of transilluminating the workpiece. A particular adaptation to material colour and ocular sensitivity by selecting light colour, radiation wavelength and time function of the irradiation is represented, and application according to the invention of suitable variants of the stroboscopic effect is required. The utilisation of fluorescence and/or luminescence by means of material irradiation with suitable wavelengths, for example UV radiation, is provided in order to obtain, for example, a clear visual contrast between thread and material even when no contrast appears in normal light. The stroboscopic effect is explained with regard to sparing the eyes, and economical teachings for achieving the stroboscopic effect are given. The advantages of the invention are substantiated even in the case of the simplest embodiment in domestic sewing machines. Original abstract incomplete.
