Title: Axle number detector for rail vehicle without marking generator - uses axle counter and marking detector of other vehicle whose actuating points are offset in distance in rail direction
Inventor: SANDER HEINRICH DIPL ING
IPC: B61L25/04
Filed: 1979-07-31
Abstract: The detector is used for determining the number of axles for a rail vehicle without using a characteristic symbol generator, coupled between rail vehicles fitted with such a generator. The detectors utilises a track side axle counter and symbol detector. The actuating points of the counter (AZ) and detector (AE) are spaced in the track direction. Time spacing is less than the smallest operational distance between an axle and adjacent symbol generator (A 11 1, etc.) To each vehicle fitted with a generator, is associated not more than two such generators, containing its number of axles and a specific symbol for the vehicle. The actual and passed symbol are stored in a memory (S1,S2), coupled to a comparator (V) for transmission of a control signal when different symbol has been detected. This signal actuates switching elements (S,A1) for subtracting the stored number of axles from the counter state. The difference is passed into a recorder (R).

Title: Shoe with integral sole and edge strip - has sole moulded using edge strip as seal to mouth of mould
IPC: B29D35/06
Filed: 1980-12-09
Abstract: Method of producing a shoe with integrally moulded sole, where the edge of the sole is surrounded by a strip projecting slightly above the sole upper face, is as follows. This strip has an inward curling beading at its upper edge, and the strip is inserted in the casting mould, it thus closes the upper mouth of the mould, into which the shoe upper, mounted on its last, is pressed. The upper and last force the strip against the inner face of the mould, the elastically deformable beading assisting in forming a seal. The sole is then integrally cast between the upper and the base of the mould. Pref. the combination of last and shoe upper presses an inner sole against the sealing beading of the surrounding strip. In a variant a pref. plastics support sheet is placed inside the mould to bear against the surrounding strip, before the mould itself is filled with the sole material. The inner surface of the main frame of the casting mould pref. has a cut-back or groove, into which the upper edge or beading of the strip can be pressed.
