Title: Radio communications system interrogating circuit - uses interrogation code for outstation group and which moves on to next group if no reply to code is received
Inventor: GUIGO JEAN-PAUL RAYMOND
IPC: H04W68/00
Filed: 1977-07-29
Abstract: The radio communications system has devices at its control centre to interrogate simultaneously a complete group of outstations using an interrogation code. Each outstation has detectors to recognise the interrogation code for the group, to which it belongs, and transmits its own identification code if its user wishes to talk. If no reply is received from a group, the control centre moves to another group. The numbers of outstations in the groups gradually reduces as this process continues, since they are dropped from the interrogation cycle, as they eventually answer.

Title: Hammer boring arrangement for large diameter holes - has support ring for hammers in circle with one eccentrically arranged hammer
Inventor: KLEMM GUENTER
IPC: E21B4/16
Filed: 1977-12-28
Abstract: Large holes are bored by a hollow bar, on the end of which >=1 deep hole hammer is assembled off centre and is fed through the bar with a fluid under pressure. For the flushing upwards of the material of the core encircled by the deep hole hammer, the boring bar is open to the sole of the borehole, and at its other end is coupled to a means of applying suction. Inside the boring bar there is a compressed air duct to which the deep hole hammers are connected. Used to create conditions under which it is not necessary to reduce the size of the rubble to the degree previously regarded as essential, so that, with the same number of hammers, higher boring speeds are made possible. A wider choice is also made possible as regards the positioning of the hammers on the boring bar. The open bottom end of the boring bar allows cutting around the core, which is broken down by vibration.

Title: Mfg. two-ply web from foam rubber base and solid top layer - by incompletely expanding and vulcanising foamable base, applying pure rubber top ply, and completing vulcanisation of blank laminate
Inventor: GRONAU JOACHIM DIPL ING
Filed: 1978-05-31
Abstract: Mfr. of a rubber web with foam rubber substrate comprises expanding a rubber compsn. contg. expanding agent, in presence of heat and pressure but interrupting this step before vulcanisation is complete. The resulting foam web is coated with unvulcanised rubber compsn., free of any expanding agent, to obtain a blank which is finally completely vulcanised. Method disposes with prior-art method of glueing a solid web over a foam web, where the resulting laminate may fail in use owing to the adhesion of the plies breaking down and the plies detaching themselves from each other. Also, there is no tendency of the foamed substrate to increase in vol. after release of the vulcanisation pressure, thus avoiding warping of edge-curling of the prod.
