Title: X:ray equipment electronic time switch circuit - inhibits pulses to counter:comparator each time primary half wave voltage falls below limiting resistor set value
Inventor: ROSENFELDT WOLFGANG
IPC: H05G1/50
Filed: 1976-04-03
Abstract: The exposure time switch used with compact dental X ray equipment, allow a predetermined number of controlled amplitude pulses to be applied to the primary side of the high tension transformer. The primary circuit contains a latching pair of contacts and limiting resistor. In parallel with the limiting resistor is a regulating resistor that switches a Schmitt trigger stage over an opto-coupler. Each time the half wave voltage to the primary falls below the value set by the limiting resistor, pulses are inhibited from passing into a counter-comparator circuit until the next positive half wave. When the comparator outputs at the required value, latching relay is reset to give the correct exposure.

Title: Stabilised sliding seat support for bus - has mating U-section slide rails sandwiching bearing rollers providing smooth running
Inventor: WOLF GERHARD
IPC: B60N2/07
Filed: 1976-06-03
Abstract: The bus seats are fitted on transverse slide rails so that the inner seats can be moved towards the gangway to increase the seat space, and moved away from the gangway to ease the access. The slide rails have U-shaped sections set over each other to enclose a space in which the weight of the seat is supported on rollers or similar bearings (205). The upper rail, attached to the seat, is fitted with bearing supports (219) to which are attached extra rollers (215) which do not reach to the floor of the lower guide, but which grip under the turned over upper edges of the lower rail. The extra rollers engage the upper edges of the lower rail when the seat is subjected to lateral forces, which would otherwise strain the normal sliding bearings.

Title: Rotary positive displacement machine with parallel shafts - has two rotors with helical teeth, grooves and generates leading flank vector
Inventor: RIEDL ALOIS DIPL ING
IPC: F01C1/08
Filed: 1977-04-26
Abstract: The rotary positive displacement machine with parallel shafts has two rotors with helical teeth, helical grooves respectively. The leading flanks in the grooved rotor are generated by a vector ( ) with its origin (1) at the intersection between the pitch circle (2) and a radial line (3) through the groove root. The character of this vector is such that it reaches a min. value at between 10 and 65% of the groove depth; increases again thereafter. It reaches this value (min.) after not more than 45 deg. of rotation from the flank's outermost point; travelling along less than half the flank length.

Title: Kiln for firing ceramic mouldings, esp. roof tiles - ensures uniform heating and colouring during tempering in reducing atmosphere
Inventor: EUSSEN LEOPOLD HUBERT JOSEPH
IPC: F27D9/00
Filed: 1977-09-22
Abstract: Kiln has a fixed floor on which the batch of mouldings to be fired can be stacked. The floor has a number of openings for venting the gases into collector channels forming part of the floor and joining a common main flue. As soon as the gases vented from the kiln enter the collector channels, their temp. is lowered by cold air delivered along feeder channels connected into the collector channels at the points where the vents in the kiln floor open into them. The cold air channels may be formed in the kiln floor and have branches into the collector channels where the vents in floor meet them. One or more cold air channels may be installed in the stack of mouldings inside the kiln. The arrangement overcomes the difficulty that in normal ovens of this type so much heat is accumulated in the floor of the kiln that the bottom zone of the core of the stack of roof tiles maintains a much higher temp. than the other parts.

Title: Measurement of moisture content of flowing solids - using capacitance technique in diverging section with radially arranged electrodes and device to maintain solids compaction

Patent DE-2743414-A1 (DE)
Title: Winding machine for toroidal coils - includes endless chain to carry wire round core, with hook drawing remaining wire through core after each turn
Inventor: CONNOR JOHN
IPC: H01F41/08
Filed: 1977-09-27
Abstract: To assist the automatic winding of toroidal coils round aring core (10) an endless chain (14) is employed. Typically, it is of the roller type with a split link to allow initial threading through the core centre. The winding wire (20) is threaded through one link (16) in the chain and the wire end (11) secured to a fixed point. As the chain is then rotated round sprockets at each end (12, 13) of the core, the wire is threaded through the bore. After one pass, a hook (27, 28) pulls the remainder of the free length of the wire (20) through before the next pass is started. The wire has to be cut to the required length before starting the winding operation. As each pass is completed, the core may be rotated through a small angle to ensure that the individual turns lie neatly side by side. Chain drive, hook, and core rotation can be combined into an automatic process. This winding method is particularly useful on cores with small dimension, for example with less than 4 cm bore dia.

IPC: F41A21/08
Filed: 1978-01-02
Abstract: The rifle has an upper barrel (2) for shot and a lower barrel (3) for bullets. The two barrels are held together by a common holder (4). The holding part for the bullet barrel (3) has a longitudinally oriented roller body guide (6) having balls as roller bodies. The roller bodies (7) prevent the barrel (3) being deflected radially but allow said barrel to move axially, for example as a result of thermal expansions during rapid firing. Bracing of this bullet barrel (3) with respect to the barrel (2) for shot is prevented. <IMAGE>
