Title: Telephone PBX with preselected evaluation - has multiple utilisation of extension control unit for loop stage cyclic testing
Inventor: FRANCHI BRUNO
IPC: H04Q3/62
Filed: 1973-08-23
Abstract: The preselection evaluation deals with the first dialled digit in order to distinguish between directional and special digits for dialling tow-digit numbers of internal extensions. The first dialled digit is received in a binary store in a connecting circuit connected to the calling extension, evaluated there by a preselection evaluation device, and when a directional or special digit is recognised, it is transmitted to the extension control device; when a complete dialling is recognised, the stored digit is converted and then re-applied to the binary store as a new binary signal; the second dialled digit is added to it, and the whole number passed to the extension control device.

Title: Control cables for pusher tug - using one cable with two loops and with cable tensioner and brake
Inventor: HARMS HORST DIPL-ING
IPC: B63B35/70
Filed: 1973-10-15
Abstract: The bows of the tug are pushed into a recess in the middle of the stern of the last barge. A single cable has the two ends secured at each end of the stern of the last barge, with the main part of the cable looped over tensioning blocks on both sides of the tug. Further tensioning blocks are mounted on a cross support pivoted about a middle vertical axis, with the last loop taken over a brake roller at the stern of the tug. The cross support is pivoted using two hydraulic rams with the tilting to either side controlling the relative lengths of the two cable sections, and hence the relative setting of the tug w.r.t. the barge. If one cable section breaks the brake is applied and steering control is possible with the remaining loop.

Patent DE-2358230-A1 (DE)
Title: Seal for pressure or vacuum chambers - which is internally seated and readily accessible for replacement
Inventor: GRASS JOHN WESLEY
IPC: D21F3/10
Filed: 1973-11-22
Abstract: The sealing system is designed to maintain vacuum or pressure conditions in a chamber e.g. of the type where a pressure/vacuum roll rotates inside a static outer shell. Each sealing arrangement consists of a base which is fixed to the outer static cylinder and in the non operable condition the sealing surface is 'held' away from the inner roll by a spring thus increasing seal life. When two internal valves in the system are inflated, with a fluid, the tension of the spring is overcome and the seal is urged against the wall of the rotating vacuum/pressure roll. Deflating the valves reverses this procedure.
Patent DE-2358283-A1 (DE)
Title: Spark ignition motor vehicle IC engine - has manual control to prevent compression ignition after electric ignition is switched off
Inventor: HOLLINS JESSE RICHARD
IPC: F02D11/02
Filed: 1973-11-22
Abstract: The engine throttle is turned by a lever connected to the accelerator pedal by a linkage which includes a strong tension spring. The linkage moves the throttle against a weaker spring which returns the throttle to idling conditions when the pedal is released. A knob on the vehicle dash-board is attached to one end of a flexible cable the other end of which passes through a slot in the throttle lever and ends in a block. When the driver pulls the knob the cable pulls the block up to the lever and then turns the lever against the strong spring in the accelerator linkage to bring the throttle to a shut off position even if the accelerator is being mistakenly depressed by the driver as he switches off.

The components are then forced together as the connection is made. The bracket is made from metal and the rivet or bolt from metal or plastic. An additional design has two rectangular legs on the key hole shape recess.

Title: Explosive welding of non weldable materials - using a tube which is compressed over the end of a rod
Inventor: PRUEMMER ROLF DR ING
IPC: B23K20/08
Filed: 1974-03-29

Title: Testing hot sealed container joints - by comparing actual value of distance between joint edges with nominal value
Inventor: BRACHT FRIEDRICH WILHELM ING G
IPC: B29C65/82
Filed: 1974-07-19
Abstract: Testing of hot sealed joints on containers having a plastic inner lining, e.g. aluminium cans for foods, is effected, during or after the prodn. of the joint, by (a) measuring the actual instant value of the distance between the two outer edges of the joint, (b) comparing the actual value with a nominal value and (c) actuating a defect signal when the difference between the instant value and the nominal value is greater than a predefined value. Process is rapid and accurate and independent of the sealing method used. Failed joints can be repaired, or the containers can be used within a safe period, thus reducing lanes of containers and their contents.

Title: Image intensifier and converter tube - has luminescent screen whose electrons exposed parts take up potential slightly deviating from applied one
Inventor: LIEB ALBERT DIPL ING
IPC: H01J31/50
Filed: 1974-07-30
Abstract: The image intensifier tube has luminescent screen under external positive voltage, onto which impinge accelerated electrons. The material, the luminescent layer thickness and structure are of such design that under normal operating conditions the screen parts, on which the electrons impinge, take up a potential only slightly deviating from the voltage applied to the screen. When electron beams higher than under normal operating conditions occur, the parts bombarded by these higher electron beams are charged to a potential of considerably negative value, as compared with the voltage applied to the screen. The luminescent screen preferably consists of several superposes layers one which is a phosphor layer.
