Patent DE-2905077-A1 (DE)
Title: Ignition delay circuit for propulsion system for projectile - has diodes preventing ignition capacitor charging prematurely due to broken supply wires shorting together
Inventor: MUELLER UDO ING GRAD
IPC: F42C11/06
Filed: 1979-02-10
Abstract: The ignition delay circuit has the voltage source (8) connected to its supply terminals (2, 3) by wires (4, 5) that break on launching or firing. A first diode (D1) is located between the first terminal (2) and the shared plate of the two capacitors (C1, C2). A second diode (D2 or D3) is connected to one of the terminals (2 or 3). The diodes ensure that the circuit functions reliably even if the two wires about circuit when broken. The first capacitor (C1) is charged via the two or three diodes (D1-D3) from the voltage source before launching. The ignition capacitor (C2) is not charged. When launching occurs the wires are broken. Should the wires now touch one another, the diodes prevent the first capacitor discharging and the ignition capacitor from being charged by the first capacitor.

Title: Split forming plate parting system - holds top plate between ram and punch and drops onto conveyor after parting
Inventor: SVOBODA ERHARD
IPC: B28D1/00
Filed: 1979-03-15
Abstract: The parting system is for split plates produced in pairs and joined together by pencil shaped ribs, particularly thin ones as used for wall cladding etc. One of the two plates is held against a stop while pressure is applied to the other so as to part them from the ribs. The pairs of plates (2, 3) are delivered flat by a conveyor belt (1) and at intervals at least equal to their length, and past a stop (5) to the side of and above the level of the belt, at the level of the bottom plate (2) resting directly on the belt. The top plate (3) is then thrust by a ram (8) acting in the direction of the stop and towards an opposite punch (6) offset from the latter so that it is held suspended between the two. On retraction of the ram, it drops into the free space on the belt between the bottom plate, which has meantime been indexed forward, and the next pair of plates.

Title: Low hysteresis position indicator for magnetic valve - has proximity detectors sensing control element piston and driving relay
Inventor: HOCK GERHARD
IPC: H03K17/97
Filed: 1979-08-11
Abstract: The indicator for a magnetically actuated control element (16) is esp. applicable to magnetic valves. It has two inductive proximity transducers (19,20) producing signals dependent on the position of the longitudinally moving control element which carries a metallic part (18) or piston. The control element position is indicated accurately using a simple arrangement with low hysteresis and low temp. sensitivity. The metallic part (18) moves within a small distance of both detectors (19,21) which are radial to the control element longitudinal axis, and are connected to a common circuit (28,29, 31,32). The proximity detector supply connections (22,23;25,26) are connected to a common direct voltage source (31). Their signal outputs (24,27) are connected to a relay (32). With the piston centrally positioned the relay is on. When it is displaced the relay is deenergised as one detector switches off.
Patent DE-2938507-A1 (DE)
Inventor: KIPFER PETER
IPC: G01G19/44
Filed: 1979-09-24
Abstract: The upper part (1) is connected in a stable manner to the lower part (2) of the balance by means of four pins (5) made of stainless spring steel. Each pin (5) is pressed with one end into a bearing piece (7) which is removable at the end of a carrier (3) arranged in the lower part (2). There are two elastic carriers (3) which extend parallel to one another and which are clamped to the lower part (2) in their middle parts. The other end of each pin (5) is pressed into a bearing piece (10) which is retained removably on the upper part (1). The pins (5) can be subjected to tensile load. Each elastic carrier (3) is supported on the lower part (2) via a respective helical spring (8) arranged on both sides of the clamping point (6). These helical springs (8) are displaceable to a limited extent transversely relative to the carrier (3) in a transmission lever (19). As a result of the displacement of the helical springs (8), the electrical signals of the measuring elements (4) attached to the carriers (3) are balanced mechanically during calibration. <IMAGE>

IPC: C07C309/47
Filed: 1979-11-30
Abstract: 2-i-Propylaminonaphthalene-1-sulphonic acid of formula (I) (where R is i-Pr) is novel. The prodn. of N-substd. 2-aminonaphthalene-1-sulphonic acid cpds. of the formula (I) (in which R is the radical of an amine capable of exchange with the OH gp. in naphthalene derivs. under the conditions of the Bucherer reaction) involves reacting salts of 2-naphthol-1-sulphonic acid and amines in the presence of SO2 at elevated pressure and elevated temp. The resulting salt is reacted with an amine of the formula H2N-R and the prod. is worked up, opt. using adsorptive and extractive purificn. processes. Reaction is carried out at 100-140 deg.C for 1-100 h, pref. using an aq. soln. contg. 5-50 wt.% (II) and with a (II):(III):SO2 molar ratio of 1-2:20-1:10. For the prodn. of (II), an alkali metal (Na or K), NH4(+) or Me2CHNH3(+) salt (III) is reacted e.g. with i-PrNH2 in aq. medium in the presence of SO2 at 1-4 bar and 100-130 (105-115) deg.C for 20-50 (35-40) h, using a (IIA):(IIIA):SO2 molar ratio of 1:5-15:1-10 (1:8-14:4-8, esp. 1:12:6).

Title: Tunnel kiln for drying or firing tiles - has through platform supported by insulating structure forming vibratory conveyor (NL 15.7.80)
Inventor: BARBONI GIORGIO
IPC: F27B9/24
Filed: 1980-01-10
Abstract: Elongated platform on which goods to be processed are moved forward, extends through a kiln for prodn. of glazed tiles. The platform is supported by a structure extending through an opening in the bottom of the kiln, which is narrower than the platform. Supporting structure, in its turn is held by links attached at their bottom end to a bearing plate on which a vibrator plate is fixed. Elastically deformable props or struts capable of limited motion support the bearing plate and are fixed to an anchorage plate. Used to replace the bogies of tunnel kilns for the prodn. of tiles of all kinds, by a vibrating surface, which results in a threefold advantage. Firstly, considerable economies of energy are made, secondly the ceramic goods of whatever shape can be fired on a perfectly flat surface at a forward speed which can be regulated according to programme and thirdly, equipment and maintenance costs are reduced. A kiln of the same breadth and length as normal, i.e. 2m. x 60m. offers great economies in bogies, moulds, handwork, storage room, etc. since pieces of any size can be laid on the platform without other support.
