Title: Interlocking polygonal concrete paving stone - has full depth corner recesses combining with others to form hole pattern
IPC: E01C9/00
Filed: 1978-07-19
Abstract: Made of concrete or similar material, the paving stone (1) is of regular polygon shape in plan, esp. hexagonal. It has recesses (2) at its corners, extenting over its full thickness. When stones are laid together, these recesses combine in the abutment areas to form regular holes in the paving. These may be filled with mortar or other hard-setting material. Alternatively, plugs of wood, concrete plastic or other rigid material may be inserted in them. In production, individual stones are laid on a non-compacted gravel layer, subsequently compacted by vibration, and depressions are pressed into the gravel layer, to form the recesses. This can be easily made without risk of damage, and provides improved bonding vertically to the paving plane as well as in that plane.

Title: Redox measuring system esp. for water preparation - has dosing jet(s) near measuring electrode introducing acid substance during measuring pauses
Inventor: BACHHOFER BRUNO
IPC: G01N27/416
Filed: 1978-11-07
Abstract: The redox (oxidation reduction) potential measuring system is esp. for water preparation. A measuring electrode is inserted into the specimen liq. to be investigated. The measuring process is interrupted from time to time. During each pause a quantity of an acid substance in liq. or dissolved form is introduced into the specimen liq. by means of at least one dosing jet in the region of the measuring electrode. The measuring electrode can be surrounded by a housing having openings for through-flow of the specimen liq. the dosing jet opening into this housing. The specimen flow can be stopped during the measuring pauses. The pressure difference between the flowing and still periods can be used to introduce the acid substance. This arrangement counteracts any tendency to form alkaline deposits.

Title: Straight bar knitting machine - has fabric-forming elements adapted for high speed running
Inventor: STRONG BARRY COLIN
IPC: D04B11/02
Filed: 1979-01-11
Abstract: A straight bar knitting machine has a knitting bed where the knitting elements (e.g. the needles, the knock-down elements and the sinkers) are mounted on bars, with levers supported to pivot, and connecting rods connecting the levers and the bars, either directly or indirectly, to impart appropriate movements, e.g. advance and withdrawal, or rise and fall to the knitting elements in order to produce a fabric. The levers, for a predominant number of the knitting elements extend from a pivot region into an L-shaped zone, and are connected by connecting rods directly, or indirectly, to a moving bar or bars for forming the fabric, in a zone opposed diagonally to the pivot region, in quadrangular configurations formed by the respective levers and the connecting rods, as seen from the side. The knitting machine is capable of working at higher speeds than were previously possible. The construction is compact, economical and runs well even at standard speeds. The mechanism may be adapted to a double bed knitting machine.

Title: Gas blast circuit breaker - with arc plasma chamber around power contacts receiving compressed gas through nozzle by pump
Inventor: HEISS WERNER DIPL ING
IPC: H01H33/915
Filed: 1979-03-09
Abstract: A gas blast circuit breaker is fitted with a nozzle through which an integral pump injects compressed insulating gas (sulphur hexafluoride) into the arc plasma cloud, produced during a cut-off operation. The space in which this gas is blown is surrounded by a cylindrical part in which a guard carrying the nozzle is guided with a sliding fit. Insulating nozzle with guard and moving power contact are coupled to the cylinder of the injection pump and can be moved during the cut-off operation relative to a stationary piston. The space in which the arc plasma is produced is thus securely screened even transient oscillations of high voltage can be mastered without arcback.

Abstract: The materials or textiles contg. these fibres admixed with other fibres, are dyed, by the exhaust or pad-steam method, in the presence of the usual assistants and oxidants inhibiting the reductive degradation of the dyestuff. In this process, the bath contains 0.01-2, pref 0.06-0.3 g/l nitrite ions, as oxidant (corresponding to 0.1-0.5 g/l NaNO2 or KNO2). The use of nitrite ions significantly improves the dyestuff yield and ensures reproducible results.

Title: Steplessly adjustable chain drive - has single chain and set of epicyclic sprockets with adjustable triangular oscillating segment
Inventor: GRUB WALTER
IPC: F16H9/26
Filed: 1979-03-13
Abstract: The steplessly adjustable positive chain drive uses a set of epicyclic sprockets (2-4), round which a single chain (5) is passed. The kinetic energy is transmitted by a triangular segment (6), on which two of the sprockets are mounted (2), the ratio being varied by the setting of the segment. The segment (6) transmits kinetic energy by performing a rocking or swinging action. The amount of rocking performed during normal operation determines the effective gear ratio.

Title: Sheet feed mechanism for printing press - has switch locking stops and stopping separation mechanism on detection of feeding fault
Inventor: EMRICH HELMUT ING GRAD
IPC: B65H7/06
Filed: 1979-05-30
Abstract: The mechanism feeds sheets sequentially from a stack to a printing press, these being delivered in staggered formation over a table to front stops aligning them before delivery to the press. The sheets are monitored by sensors. If there is a feed fault the sheets are halted by locking the stops in place. A fault actuates a switch (S1), which both activates the stop locking mechanism (10) and stops that separating the individual sheets (2). At the same time a further cut-in switch (S2) is prepared, being closed by a contact (k1) when a specific operation is performed, so as to set the separating mechanism and stops into motion again.

Title: Automatic location of chaplets on cores for mfg. hollow castings - where template carries vertical magazines, each filled with stack of chaplets fed downwards onto cores
Inventor: FOEBUS LUDWIG
IPC: B22C21/14
Filed: 1979-06-12
Abstract: A template is provided with a pattern of holes so that all the holes can be aligned over specific zones of cores. Each hole contains a tubular magazine filled with a stack of cores; and the bottom end of each tube is fitted with fingers mounted on levers so the chaplets can be released one by one from the magazine. In the pref. chaplet delivery machine, the fingers are operated pneumatically or mechanically, and the chaplets are loaded into the magazine tubes directly after their mfr.; the delivery of the chaplets is fully automatic. With the continuing automation of foundries, the size of core boxes continues to increase, and the number of cores per core box is now very large. The invention eliminates manual labour and damage to the chaplets and the cores.
