Title: Cinematograph camera synchronised to tape recorder - with synchronisation circuit which ensures continuity of synchronisation across joints in film sections
Inventor: SANDL DIETER
IPC: G03B31/04
Filed: 1973-09-28
Abstract: The cinematographic camera has a synchronisation pulse contact in the drive mechanism for generating a pulse train for synchronisation of a magnetic tape sound recorder, the pulse recurrence rate standing in a specific relationship to the frame frequency of the camera operation, with a switch bridging the trigger switch under the control of the pulse generator so as to operate periodically at the frequency of the synchronising pulse train in such a way that the end of the closing phase coincides approximately with the end of the synchronising pulse. This ensures that film sections taken at different times can be connected without losing continuity in synchronising between the different sections.

Title: Plastic and cardboard container stacking mechanism - uses air current for alignment before vacuum testing and internal cleaning
Inventor: MEYR LUDWIG
IPC: G01N21/88
Filed: 1973-10-27
Abstract: The plastic or cardboard containers are delivered in bulk and unsorted, and are separated, tested, counted, aligned and stacked before onward transport, in a unit with an outer wall tapering slightly inwards from the base. After mechanical separaton, the containers are aerodynamically aligned soley by an air current. They are then first tested for weight and shape, cleaned of any external foreign bodies adhering, and any abnormal ones separated out, while at the same time being raised in a predetermined attitude. A second test under vacuum, with simultaneous internal cleaning, is then carried out, any damaged ones being rejected, while the remainder are held by vacuum and transported to the discharge position. Here they are stacked, and conveyed away each time a set number of items has accumulated in one stack.

Title: Multi-cell battery - has valves in cell dividing walls and end outlet valve to release gas
Inventor: MOLL PETER J
IPC: H01M2/12

Each dividing wall has a hole sealed either by a membrane or by a valve. The end of the battery housing has a plug or another valve inserted through it. As the gas pressure in the separate cells increases so the appropriate valves open and finally allow the gas to escape to the atmosphere through the end outlet valve. The valves are sited above the level of the battery electrolyte.

Title: Clamping device for grindstone on shaft - has serrated jaws or plates tensioned against side of grindstone to secure it to spindle
Inventor: SALJE ERNST PROF DR ING
IPC: B24D5/16
Filed: 1974-02-02
Abstract: A clamping arrangement for holding a grindstone onto its spindle includes a pair of plates with serrated faces which are held tightly against the side faces of the grindstone so that the serrations engage the rough surface to ensure a good grip. These plates may be drawn into contact with the grindstone by a collar and sleeve pulled together by bolts, or a pair of serrated jaws is pulled against the grindstone by a clamping collar which pulls the jaws up against a shoulder on the spindle. In an alternative method the serrated plates are clamped against the grindstone by an adaptor which fits inside the bore of the grindstone, and adhesive is included between the teeth and the rough grindstone surface.
Patent DE-2407717-A1 (DE)
Title: Overload warning device for hydraulic excavators - has measuring instruments to monitor warning pressure in lifting cylinder
Inventor: KIJEWSKI JOACHIM
IPC: B66C23/90
Filed: 1974-02-18
Abstract: Overload warning device for hydraulic excavators used as cranes with measuring instruments to monitor the warning pressure produced in the lifting cylinder of the main boom before achievement of the tipping moment by the load to be lifted as for example with pressure switches and associated manometers connected with the lifting cylinder of the boom and releasing optical or acoustic signals. There is a hand pump between the lifting cylinder and the measuring instruments and with this a test pressure is generated which corresponds to the warning pressure by operating the hand lever moving the pump piston in the range of a limited stroke. In a rest position outside this stroke its pump piston frees the pressure connecting between lifting cylinder and the measuring instruments. In a second rest position the pump piston cuts off this pressure connection and thus effects the cut out of the electrical part of the warning device.

Title: Contact arm and spring for connection to wire - placed in multipin linear electrical connector
Inventor: MARQUARDT ERICH ING GRAD
IPC: H01R4/52
Filed: 1974-10-26
Abstract: Each terminal comprises an insulated housing (1) which holds a spring clip (7) with one free end (6) and one end (4) which forms the pin or contact carrier (22) of the connector (5). The clip has a hole (8) through which the incoming wire end (9) is passed when the clip is in a horizontal position. With the wire in place the clip can be pushed over, for example by means of a screwdriver inserted through a slot (17) in the housing, until it snaps into its second, angled position where the free end (6) exerts pressure against the wire end (9) forcing it into contact with the opposite end (4) of the clip. A hole (21) on the opposite side of the housing permits release of the wire in a similar manner.
