Title: Thermal denaturing appts. for a histological laboratory - has containers for hot and cold water with temp. control
Inventor: SCHUBERT WERNER DR MED
IPC: G01N1/31
Filed: 1992-11-21
Abstract: The appts. for denaturing fresh tissue with heat, in a histology laboratory, has containers (1,9) of different sizes and shapes to hold water (6a,6b) for the thermal denaturing of sample excisions (8) or large fresh organs (8). They serve for hot-water (6a) and cold water (6b) for cooling, and are of thermal conductive material. The hot and boiling water (6a) is protected through the boiling point of 100 deg.C, and is brought up to boiling point by pulsed heating with a heating control, electro-heater, time switch, thermometer (11) and electronically controlled relays to give the required denaturing temps. of 70 deg.C and 90 deg.C with controlled heat pulses in the heating channel. Various heating pulse frequencies are used with a corresponding disconnection of the power for the temp. ranges between 60 deg.C. and always automatically at 100 deg.C. The base temp. is reduced and a constant heat loss through the container wall gives an automatic cooling. Frequency increases are used with increased artificial cooling. USE/ADVANTAGE - The system is for denaturing fresh tissue in a histological laboratory. The appts. and its operation gives an effective denaturing of fresh tissue and organs, without using formalin.
Patent DE-4241300-A1 (DE)
Inventor: MOESCHLER FRANZ
IPC: B61F5/14
Filed: 1992-12-08
Abstract: Twin axle drive or connection of two twin axle drives which save on overall height and mass in the short powerflux of the perpendicular loading and ensure, when travelling in a tight bend in the track, the necessary rotation angle with an acceptable rotation resistance and ensure transverse play better than a link suspension. According to the invention, the object is achieved in that the leaf springs (10) are coupled at their ends to the wagon stays to the side of the lateral members (3). A support pendulum (14) is supported on the spring collar (11) of the leaf springs (10) and rolls with the necessary resistance in the longitudinal direction of the vehicle without restoring force and thus brings about the necessary restriction on rotation. In the transverse direction, the restoring force and transverse restriction required for transverse play is produced by the design of the crowned rolling segment of the support pendulum (14). In the connection of two twin axle units, steering is effected by a Beugniot lever. Both axle units are connected to a transverse coupling. The invention is preferably suitable for use with low-level wagons (1) with a continuous floor height and small wheels. <IMAGE>

Title: Vehicle bumper with pushing facility - has correspondingly shaped bumpers to match bumpers of other vehicles and with optional isolator switch for collision protection
Inventor: ZURELL ARNOLD
IPC: B60K28/14
Filed: 1992-12-15
Abstract: The front and rear bumpers of vehicles are shaped to fit into each other, allowing one vehicle to push another disabled vehicle without requiring a tow rope connection. The bumper supports are fitted with collision sensors which immobilise the vehicle electrics. During retrieval of a disabled vehicle, the driver of the disabled vehicle can determine the speed and direction of travel. For downhill travel the vehicle can coast unassisted. The bumper supports can be damped and the level of cut-out for the immobilising switch can be adjusted. USE/ADVANTAGE - The shaped bumper provides a simple removal of disabled vehicles while the immobilising switch prevents fires in a collision.
