Title: Stock inlet -  has movable upper wall to set suspension delivery point at the fourdrinier without pivoting the jet assembly
Inventor: BUBIK ALFRED DR
IPC: D21F1/06
Filed: 1990-09-18
Abstract: The stock inlet, for a paper-making machine, has an upper limit wall for the jet outlet which can be moved to alter the point where the emerging suspension meets the horizontal moving fourdrinier. Pref. the upper limit wall moves generally in the direction of the suspension flow. At least one divider is within the jet section of a multilayer delivery jet, for the outlets to give suspension in layers, in succession, in the direction of fourdrinier travel. The outlet for the lower suspension layer is further advanced to give a later delivery to the fourdrinier than the other suspension layers. An elastic film is fitted to the end of the rigid divider. The upper divider and upper limit wall is set back from the lower wall, against the suspension flow direction, by a length (L) which is 0:10 each of the jet outlet heights (H). The pitch angle (alpha) of the divider is between -10 deg. to +30 deg. to the fourdrinier plane. ADVANTAGE - The level of the emerging suspension, from the stock inlet, can be adjusted reasily to give the max. effect, without pivoting the jet assembly.

Title: Laser beam shooting simulator - has laser beam directed to precisely simulate flight path of bullet fired from gun
Inventor: SIEBECKER HANS DR
IPC: F41G3/26
Filed: 1990-10-19
Abstract: The shooting is formed as a gun and provided with a laser emitter (3) whose adjustable beam path is aimed at a target centre and produces a light spot when a hit is made. The dia. of the laser beam corresponds to that of the missile being simulated. The target distance is estimated or measured with a laser distance measurer. From this measurement the corresponding angle of inclination of the gun barrel (8) is determined from the weightless precise beam. Directly before shooting the laser (3) is directed by a mirror aiming sight (5) inside the barrel (8) to slope downwards by the determined amount. USE/ADVANTAGE - For hand shooting, to simulate the flight path of a bullet. The angle of the beam is precisely and automatically calculated using a simple system, which closely resembles a real gun.

Patent DE-4107011-A1 (DE)
Inventor: WILD RAINER DR
IPC: B29C45/73
Filed: 1991-03-05
Abstract: The invention concerns a process and a device for producing blow-moulded hollow bodies (11) made of plastic, preferably PET. A cast, hollow, hot preform (11) is placed in a hot blow mould (14) and the material is expanded until its walls adopt the desired shape of the hollow body. Different regions of the wall are subjected to different degrees of expansion, depending on the desired shape of the hollow body. To modify such a process and such a device to produce reusable hollow bodies, it is proposed that, before blow moulding, additional heat be supplied by an additional heater (13) to transition regions (11c) of the wall of the preform between wall regions subjected to different degrees of expansion, in particular between a wall region subjected to little or no expansion and a wall region subjected to greater expansion.

Title: U=shaped lamp reflector with radiation direction vertical to plane of lamp location - comprises three sections which evolve by rotation of cross=section line around rotary axes to give max. possible light density over complete reflector
Inventor: WILLING ACHIM DR ING
IPC: F21V7/00
Filed: 1991-04-11
Abstract: The low pressure discharge lamp is bent U-shaped, and of the three sections of the reflector one (R1) takes in the basic surface of a semi-circle with the rotation axis through the middle point (M1), which at the same time is the rotation centre point of the bent part of the lamp, with the semi-circle diagram being greater than the bent part of the lamp. The other two reflector sections (R2,R3) are symmetrical w.r.t. a line (S-S) of the lamp, and their rotary axis passes through the straight arm of the U-shaped lamp, their dividing line being the symmetry line (S-S). They either abut directly on the semi-circular reflector section (R1), or on a further reflector section (R4) which has a rectangular basic surface, and is produced by displacement of the cross-section line of the first reflector section (R1) along the arms of the U-shaped lamp. ADVANTAGE - Lamp has reduced structural depth, and radiates with maximum light strength in main radiation direction.
Patent DE-4125141-A1 (DE)

Title: Laser printing of plastic identity cards, etc. - includes using transportable appts. not requiring water cooling
Inventor: BLOME RAINER
IPC: B23K26/08
Filed: 1991-09-25
Abstract: The installation for time-controlled application of a laser beam (L) to an identity card (A) uses a two-coordinate beam deflection system (ZA) to produce a laser record on the card. It is characterised by the fact that the beam (L) is generated in a Neodym-YAG laser (1). This laser is powered by a semiconductor pump diode (2) provided with amplitude and/or pulse-length modulated current by means of a modulator (3). The modulator (3) is controlled by a signal (SS) from a signal converter (4) which processes the input grey-level signals to compensate, jointly with the time constants of the diode (2), the blackening nonlinearity of the card (2). The reflected laser light is fed directly to a photosensor (PS), and the output signal from this sensor is used to control the diode (2) via the modulator (3). The signal converter (4) includes an image storage (BS) and an image processor enabling changes to be made in an image section and/or a grey-level before the resultant signals are fed to the modulator (3). The deflector (ZA) contains a single spring-mounted mirror which can be swivelled in two coordinate directions by two controllable force sources. The mirror is a concave mirror which can focus the beam (L) onto the card surface. USE/ADVANTAGE - The invention can be used, for example, in devices for laser printing of texts or images on plastic cards. In contrast to known installations, it operates at low power levels and does not require water cooling. As a result, it can be made smaller, lighter and transportable.

Patent DE-4139757-A1 (DE)
IPC: B28B7/28
Filed: 1991-12-03
Abstract: The invention relates to a filter pipe for dewatering during the compaction of fresh concrete or similar mixtures, especially for the prefabrication of large concrete elements, for example for construction of living accommodation. A control slide pipe (4) is arranged in the filter pipe (3), bears on the inside wall of the filter pipe and can be displaced along the axis of the pipe and can be pulled out through the shuttering (1). By means of the control slide pipes, the sequence and degree of dewatering can be adjusted in sections to the shape of the concrete element. The concrete element receives a very compact, virtually pore-free structure, and therefore a high degree of durability. The shuttering can be partly removed immediately after compaction of the element. <IMAGE>
