Title: Adaptor for car battery testing - has male and female sprung cone connections linked to test circuit
Inventor: ROESSLER HANNS DIPL ING
IPC: H01M50/50
Filed: 1975-03-01
Abstract: The battery testing adaptor comprises a profiled insulating element (17) separating female (18) and male (19) conical connectors. One of the battery terminals is removed and the adaptor fitted in its place. The removed terminal is then clipped over the male connector on the adaptor. The two connectors are bridged by a set shunt (16) so that the voltage drop across the shunt can be monitored by a measuring circuit (29) to determine the current drain from the battery. The conical male connector is set lower than the female so that the fitted adaptor has the male connector at the same height as the original battery terminal (15). For rapid fitting the adaptor connectors are made in hinged halves, spring loaded for a secure fit.

Title: Securing tapes around articles - by pushing articles through straps and joining free ends of straps
Inventor: WAL AUKE VAN DER
IPC: B65B13/02
Filed: 1975-03-27
Abstract: Tapes, which may be metal or reinforced plastics, are applied to an article, which might be a stack of individual articles, by pushing the article through joined tapes extending between pairs of supply reels to deform the tapes into a U-shape round the article. The rearwardly projecting arms of the U are pushed by tape strainers behind the articles where they are cut. The ends of the arms are glued together to secure the package and the ends of the tapes projecting from the reels are also glued to form a barrier to the next article passing between the reels. Each tape strainer includes a member having a pair of clamping surfaces which clamp the tape in two spaced regions, the tape being cut between the regions. Movement of the members towards one another causes the cut ends of the tapes to be brought together where they are glued by glue forced through one of the members.

Title: Road water film deflecting mechanism - has adjustable air jet and deflector vane fitted in front of vehicle tyres
Inventor: KUSTERMANN WALTER DIPL ING
IPC: B60B39/00
Filed: 1976-01-10
Abstract: The danger of aquaplaning is reduced by distributing the water film to the sides of the vehicle. This is done by a fixed or movable air jet that is projected to the front of either the front or both the front and rear wheels. The air jet is powered by a motor driven compressor with an electromagnetic coupling. The nozzles are fixed at the front so that they turn with the vehicle steering. The adjustment is also used to move the nozzle forward as vehicle speed increases so that the jet impinges at a point further ahead of the tyre contact. An angled water disperser or deflector is fitted in front of the tyre.

Title: Automatic take off motion for fabric leading edge - from pins of finishing stenter chains, without stopping machine
Inventor: SPURNY JOSEF
IPC: D06C3/02
Filed: 1976-04-07
Abstract: A device for automatically taking off the leading edge of a textile fabric from the needles of a stenter chain, esp. on a finishing machine, has, in front of a needle bar, on both sides of the leading edge of a band of textile fabric, a pivoting arm, at the tip of which there is a small plate trimmed with needles. In its position of readiness, the arm is held by a latch against the pull of a spring so that when the leading edge of the fabric releases the catch, the arm is pivotted on its support journal, lifting the fabric with it. It is thus unnecessary to stop the machine to transfer the leading edge of the goods from the chains to a winding reel. Enables runners attached to the fabric to be removed easily and quickly. Device is safer to use.

Title: Reverse leather lining process - by coating release substrate with polyurethane compsn. and embedding textile with passage of compsn. to bond leather
Inventor: FISCHER WILHELM DR
IPC: C14C11/00
Filed: 1976-07-02
Abstract: Leather of split leather is coated with a reactive mixt. of polyisocyanates, polyamines and opt. further isocyanate-reactive cpds., opt. with use of inert organic solvents and/or plasticisers. Process comprises first applying a layer of a system reacting with a polyurethane to a release substrate. A reinforcing textile is then embedded in layer within 15-90 sec while viscosity of reactive system is still below 1500 cP at the prevailing working temp., so that the low-viscosity reactive system can penetrate through the textile. The leather or split leather lining is then applied, and finally the composite material is sepd. from release substrate after drying. Polyurethane-reactive system embeds textile completely and penetrates through to surface to textile, to bond the actual leather substrate. Abrasion-resistant, dimensionally stable composite materials are produced in a single-stage process used partic. for the prodn. of lined leather for shoe uppers.
