Title: Safety door for car - has sloping faces over door lock to prevent lock jamming in collision
Inventor: VETTERL ALBERT
IPC: B60J5/04
Filed: 1975-04-02
Abstract: The car door (2) has a trailing edge which is angled w.r.t. a transverse plane to the car. This angle coincides with a similar one on the leading edge of the door frame (6) so that if the car is involved in a collision then any displacement of the door results in the door being forced outwards, and not jamming shut. The two parts of the door lock (10, 11) are designed so that if there is any door displacement then the door part of the lock is pushed over the frame part into a non locking position. The system enables rescuers to extract survivors out of crashed vehicles rapidly and without cutting gear.

Title: Automatic thread spooling machine - with knotting device and timer terminating cycle when thread not caught
Inventor: ROHNER JOACHIM
IPC: B65H69/00
Filed: 1975-07-11
Abstract: Automatic spooling machine has a knotting device at a number of spooling positions. Thread ends are gripped by air and fed to the knotting device. The machine reduces the downtime caused through the unsuccessful catching of the thread end. The machine is distinguished by a timer-linked to a photo cell sensing circuit which terminates the thread end seeking cycle when the predetermined time is exceeded. This prevents further action of the knotting device at this spooling position. A recurring fault is signalled to the operator.

Title: Batch process for continuous propagation of microorganisms - with supervision and control of long term cultures
Inventor: KLEMM KARL DR
IPC: C12M1/36
Filed: 1975-12-03
Abstract: In the continuous propagation of micro-organisms and analysis of their long term behaviour, measurements relative to the changing metabolic conditions are taken continuously. Whilst the others are kept constant, >=1 of the parameters arising from the conditions of the culture, and/or the introduction of foreign matter, and/or the characteristics of the organisms, is subjected continuously to a gradient in the direction of alteration towards a predetermined value. With a view to the selection and/or propagation of the organisms alpha mutants better adapted to the conditions of interest, the parameter relevant to the selection is approximated asymptotically to a limit value of the metabolic performance. The actual measured value of the metabolic performance at any time is used to control the climb of the parameter gradient. The measurements of the metabolic performance are effected via the determination of the pressure or the volume of gas in the vessel, and the signals are recorded on a time scale. Method provides specific equipment for the achievement of the selective breeding of the micro-organisms aimed at, and permits the direct supervision and recording of the metabolic performance of a long term culture.

Title: Spring back mounting for bonnet mascot - with restricted opening to prevent spring being pulled out and mascot stolen
Inventor: MOELLER HERMANN
IPC: B60R13/00
Filed: 1976-02-11
Abstract: The bonnet mascot (2) is located on a profiled plate (7) mounted in a hole in the bonnet, and with spherical bearing surfaces (4) between the base of the mascot and the plate. The bottom of the mascot is held against the bearing by a spiral spring (5) whose bottom end is secured inside the bonnet. The bonnet hole is restricted by an insert (14) or by the plate, to prevent the spring being pulled out and the mascot stolen. The upper end of the spring is attached to the mascot on a hook which extends into the centre of the bearing so that the mascot is displaced to any direction when struck. The bottom hook (11) is free to rotate to prevent overwinding of the spring. The mascot is thus tamper-proof.

Title: Local measurement or generation of microwave fields - is performed using semiconductor wave guide with longitudinal modulation of inhomogeneities
Inventor: BRAND HANS PROF DR ING
IPC: H01Q13/28
Filed: 1976-03-05
Abstract: The purpose is to produce an easily variable detector for the quick measurement or generation of local fields. It is achieved by having a semiconductor dielectric wave guide (2) coupled to suitable amplifiers (8) with conducting guides (4) and locally varying the conductivity cyclically at the desired frequency. In an example the semiconductor guide (2) is made of photosensitive material. A laser light source (5) transmits a beam via a rotating mirror (6) and fixed reflectors (7) to scan the guide length. The laser pulses are synchronised with the mirror speed to give a travelling frequency along the guide of typically 36GHz. For this frequency the guide dimensions would be 3mm x 2mm, and it would be made of silicon with a dark conductivity of 4000 ohm cm.

Title: Tracked vehicle for rough terrain - with separate half tracks individually mounted fore and aft
Inventor: REIERSDAL OLAV L
IPC: B60G5/00
Filed: 1976-08-14
Abstract: The tracked vehicle for rough ground has special half tracks fore and aft. Two half tracks are at the rear of the vehicle, and one or two at the front. All the tracks are driven, each track frame being pivotted about a horizontal, transverse axis above the frame, with an extension of the frame set above the pivot as an operating lever. Hydraulic rams (7) engage the operating levers to tilt the tracks over rough ground. The spearate suspension of each track enables the vehicle to cover obstacles without altering the tilt of the main chassis too much. This provides greater control for the driver. In military vehicles the increased stability results in better gunnery.

Title: Pressure boiler air outlet valve - comprises container with float which seals valve aperture when fluid pressure rises
Inventor: LUERTI CARLO
IPC: F16K24/04
Filed: 1976-10-21
Abstract: Air outlet valve, partic. for pressure boilers or other components of heating installations, has a container (10) connected both to the outer atmosphere and the inner space of the unit. Also incorporated in a valve unit comprising a float (28) and a closure component (36). Though the hydraulic pressure of fluid present in the container (10) the float (28) lifts against a valve opening, sealing it off. Conversely, when the fluid level in the container drops, the float (28) drops and releases the valve opening (20). The float (28) takes the form of a cylindrical hollow body whose shape corresponds to that of the container (10), its outer diameter being slightly less than the container inner diameter. Its outer wall has lateral projections (30) which enable it to be guided inside the container (10).
