Title: Photometric cell for evaluating the intensity of the change in colour of reagent strips
Inventor: VOLF RADKO DIPL ING
IPC: G01N21/47
Filed: 1987-06-16
Abstract: The reagent strip is illuminated at a certain angle  alpha  by the use of a working light-emitting diode (2), and the reflected light, which is attenuated by the change in colour of the surface of the reagent strip, is measured by means of a photo resistor (4).

Patent DE-3739122-A1 (DE)
Inventor: FRITSCH WALTER
IPC: B29C45/13
Filed: 1987-11-19
Abstract: In a device for manufacturing composite plastic mouldings, at least two different reaction mixtures are injected simultaneously through different sprues (24, 26) into the cavity (28, 28', 28'') of a mould (20, 22). During the injection time of at least one of the reaction mixture, the cavity is subdivided into two or more mutually isolated regions. Following the injection of one reaction mixture, the separation between the regions of the cavity is removed and the at least partially liquid reaction mixtures converge in the separation plane. This device makes possible to join at least two materials having different properties in a single operation. It is useful for manufacturing bumper bars, spoilers, coach-work, and internal linings of motor vehicles.
Patent DE-3739216-A1 (DE)
Inventor: OKAMOTO SAICHI
IPC: A61G5/00
Filed: 1987-11-19
Abstract: A shock absorber assembly is disclosed for use with wheels of a wheelchair. The assembly includes a slider (3) fixed to one end of a wheel axle (11) and vertically movably guided by guide rails (2) supported by upper and lower support members (5,5') secured to a side frame (1) of the wheelchair. An upper elastic member (13) is mounted between the upper support member (5) and the slider (3) so as to be compressed as the slider is moved up. A lower elastic member (14) is mounted between the lower support member (5') and the slider (3) so as to be compressed as the slider is moved down. The shock to the wheelchair is not transmitted directly to a person sitting thereon, but absorbed by the two elastic members (13, 14). Castor-like auxiliary wheels of a wheelchair may be mounted by a somewhat similar arrangement (Fig. 8). <IMAGE>

Title: Device for the inspection and/or repair of tubes ending in a tube plate of a heat exchanger
Inventor: ZIEGELMEYER FRITZ
IPC: F22B37/00
Filed: 1987-12-19
Abstract: A device of this type is arranged in a steam-generator chamber. When fastening the carrier (16) for repair tools relative to the tube plate (4) stresses arise which are based on the rigid connection of the carrier to the device parts carrying it. Therefore, a device is to be found which enables a stress-free level equalisation of the carrier relative to the tube plate. For this purpose it is provided that the releasable connection between the carrier (16) and the partial arm (11) is a coupling piece (34) which is connected rigidly to the partial arm (11) and can optionally be connected to the carrier (16) rigidly or in a swinging manner. The rigid or swinging connection between the carrier and the coupling piece is controlled by a contact bolt (23) which can be moved relative to the carrier. In its downwards movement it interrupts the pressure medium flow flowing in the conduit (56), so that the locking device (49) is switched to be unpressurised. The carrier (16) is then suspended in a swinging manner only by the spherical bolt (42). By this means a stress-free positioning of the carrier (16), dependent only on the position of the tube plate (4), is possible. <IMAGE>

Title: Torque-transmission system without differential for motor vehicles
IPC: B60K23/04
Filed: 1988-06-13
Abstract: The torque-transmission system without differential for motor vehicles with two, four or more power wheels on one, two or more divided axle shaft(s) is characterised in that each axle shaft part (5, 6) can be connected by way of a clutch (1) with steplessly controllable torque transmission to the drive train (11) and the torque transmission of each clutch (1) is separately controlled by the steering angle @, the vehicle speed and, where appropriate, vehicle-specific factors by way of a computer (2). With this system the shaft part with the more heavily loaded power wheel is subjected to the higher torque and the shaft part with the power wheel carrying less load is subjected to a reduced torque. The system according to the invention is also suitable for use in vehicles with all-wheel drive and/or antilock system. <IMAGE>

Title: Supporting leg for a scaffolding pole
Inventor: HAGEDORN HARALD
IPC: E04G5/02
Filed: 1989-02-15
Abstract: The invention relates to a supporting leg for a scaffolding pole, in particular for a batter-board apparatus which exhibits individual scaffolding poles, which can be anchored on the underlying surface and have securing means for connecting transverse elements such as wooden planks, and, for each batter-board pole, at least one supporting leg which is to be arranged at an angle with respect to said pole and exhibits, at one end of a leg member, a supporting head which can be brought into engagement with the scaffolding pole and, at the other end, a supporting foot which can be anchored on the underlying surface. In order to ensure rapid and simple mounting and demounting of the supporting leg, the invention proposes that the supporting head have at least two U-shaped fork members with in each case two fork arms and fork widths which are suitable for partially enclosing a scaffolding pole on both sides, that, with substantial alignment of their transverse openings and with mutual clear spacings, the fork members be arranged in offset planes, that said longitudinal spacing be greater than the cross-sectional dimension, such as the diameter, of the scaffolding pole, that the fork arms of the fork members point in substantially opposite directions, and that the fork members of the supporting head be connected on one side to one another and to at least one supporting-leg member.

IPC: C02F7/00
Filed: 1989-02-17
Abstract: For the rehabilitation of polluted waters stratified in summer, warm surface water is pumped into the depths in order in this mixing to increase the temperatures of the relatively cold water of the thermocline and of the cold water from the deep water region lying beneath and thus to diminish the differences in specific gravity and thus to enable wind and waves again to perform complete circulation of the water (before autumn is reached with cooling and storms), by which the anaerobic state of the deep water, with its ecologically negative symptoms, is ended.

Title: Securement of grave head-stone - by anchor bolt with split tapered end cap which is radially expanded
Inventor: KETTLER PAUL ERICH
IPC: E04H13/00
Filed: 1989-05-13
Abstract: The headstone (12) is mounted on a plinth which is supported on a foundation. The headstone (12) is held in place by an anchor bolt (1) which passes through a hole in the plinth and has its lower end embedded in the foundation. The upper end (1a) of the anchor bolt is of reduced diameter and is tapered to fit in the tapered bore of a cap (2). This cap (2) has longitudinal slots extending from its open end. The cap (2) is initially a sliding fit in the hole (11) in the headstone (12).  When the headstone is placed over the bolt (12) the shoulder in the hole in the headstone presses the cap (2) downwards on the tapered end of the bolt. The cap (2) is radially expanded and forms a tight fit in the headstone hole. USE/ADVANTAGE - The headstone for a grave can be easily removed if required, but is secure against accidental movement.
