Title: Dustproof multiple socket arrangement for telecommunication equipment - has sliding shutters sheltering spring contacts and opening with plug insertion
Inventor: FABER WALTER
IPC: H01R13/703
Filed: 1973-03-28
Abstract: The socket housing contains contact springs for insertion of a bar-shaped plug of insulating material carrying fixed contact faces. The socket mouth embodies two shutter bars at right angles to the direction of plug insertion. The two bars are wedge shaped with their edges pressed against each other by springs in the socket body and protecting the spring contact chamber when no plug is inserted. Inserting the bar shaped plug pushes the two shutters back in opposite direction against the shutter springs and to the full width of the contact mouth. The shutter springs can be torsion springs. To limit the shutter movement appropriate projections and slots are provided on them and on the housing respectively. The springy contacts of the socket are dust protected when the plugs are not inserted.

Title: Pipe coupling requiring no preparatory work on pipes - joins pipes with muff and two tapered joint rings
Inventor: MOEBIUS KURT OTTO
IPC: F16L13/14
Filed: 1973-06-25
Abstract: The coupling consists of a muff and two taper rings. The pipes, which must be free of surface scratches, are fitted into the muff, which has a small chamber on the outside diameter at each end. The rings have a tapered bore and tapered outside diameter so that the thickness at one end is about one third that at the other end. The larger ring bore will fit over the muff but as each ring is pushed towards the middle of the muff, the muff is deformed to such a degree that the tubes to be joined are also deformed, thus ensuring a pressure tight joint between muff and tubes. A lubricant is used between ring and muff.

Title: Antiskid spike for motor vehicle tyres - has wedge shaped and flanged grooved heat at thicker end
Inventor: BEEK JOSEF GERHARD VAN
IPC: B60C11/16
Filed: 1974-01-10
Abstract: The spikes are fitted into the tyre and are firmly anchored and move relatively little within the tyre during travelling. Hence they cause little noise and they do not abrade the road surfaces. during motion the tyre rubber is pressed into the groove in the spike head and hence it prevents the independent movement of the spike to a very great extent. The spike is embedded intot he tyre tread such that the narrower end projects out of the tyre and comes into contact with the road surface. The spike becomes thicker from the contact point upwards and it has a rounded and flanged head split by a groove. All corners of the spike are rounded which ensures that it does nto damage the tyre.

Title: Passage way through bulkhead for switch contact - is fitted with closing flap and spring mounted security catches to hold flap in closed position
Inventor: KOLL WILLI ING GRAD
IPC: H02B11/24
Filed: 1975-05-30
Abstract: The application is to ducts through bulkheads, for example for joining a busbar chamber (5) with a switchgear chamber (4). The duct consists of a cylindrical tube (7) mounted on the bulkhead (1), and forms an entry guide for the movable contact (3) on one side and a mounting for the safety flap (2) on the other. The flap is hinged at the top so that it falls closed under the action of gravity. It is held closed by at least two spring loaded lever arms (6) each having a recess (6a) closing round the flap, and also a boss at the outer end. Entry of the movable contact thus presses the lever arms apart thereby releasing the flap which is pushed upwards as the contact moves further in. The insertion of non-standard or foreign contacts or rods is thus hindered. The installation meets VDE 0670 part 6.
