Patent DE-4118930-A1 (DE)
Title: Safety blocking control for vehicle transmission - has gear selector shaft held by variable spring pressure bolt to prevent certain gear selection, e.g. reverse
Inventor: GIACALONE GIACOMO
IPC: F16H63/34
Filed: 1991-06-08
Abstract: The gear selector shaft (11) has a sleeve (8) with a flange (7) which can be gripped by the end of the spring loaded locking bolt (6). This prevent e.g. the selection of the reverse gear. The bolt is driven by a main coil spring (12) and a support sleeve (3) with a smaller spring (13) mounting. A solenoid operated catch (14) locks the sleeve and effectively bridges the smaller spring. The solenoid is operated above a set speed. This prevents selection e.g. of the reverse gear unless a strong force is applied to the gearshift, e.g. in emergencies. USE/ADVANTAGE - Transmissions with synchromesh on reverse. Simple transmission protection, operated by transmission processor control.

Title: Clock signals generation arrangement for several timed devices - compares system time from central timer with system time counter state to control device data access
Inventor: WEIGL REINHARD
IPC: G06F1/06
Filed: 1992-02-17
Abstract: The clock generator includes a first memory (S1) for receiving the devices' clock times has cells individually addressable via a first address bus (A1) and read via a first data bus (D1).

Title: Joining together metal and plastic parts - by positioning e.g. aluminium@ casting in mould and e.g. injecting thermoplastic polymer to fill space and shrink onto lugs when cool
Inventor: HUYER JOHANNES NICOLAAS
IPC: B60J7/02
Filed: 1992-08-19
Abstract: One metal and one plastic component are joined together, partic. in the open roof of a car, by means of a linkage with two parts; the first part is formed on the metal component which is positioned in a mould for it; the plastic is then cast so that the second part is produced engaging the first. Injection moulding can be used instead of casting. ADVANTAGE - Method eliminates the problems of earlier methods namely having to produce an additional link pin, needing to produce holes and the pin to close dimensional tolerances etc. In an example, of members of an open car roof system an arm (8) is first produced e.g. by pressure die casting in aluminium. It is then placed in an appropriate injection mould to produce the operating member (6) of e.g. polyoxymethylene or polyamide and the polymer is injected to fill the cavity. Linkage pins (14,15) projecting from both sides of the arm (8) and integral with it (8) are thus polymer-coated also. The member (6) shrinks upon cooling so that holes (11,12) in the member (6) provides a seating for the pins (14,15), and the arm (8) is permanently fixed between the member (6) and attachment (13).
