Patent DE-2549721-A1 (DE)
Title: Concrete pipe casting segmented mould - has stepped collar and base ring replaced by wooden board for drying
Inventor: JAEGER MANFRED
IPC: B28B21/76
Filed: 1975-11-06
Abstract: The pipes are cast socket-end-down (spigot-end-up) between a shaped outer mould (4) and a cylindrical inner core (6). An annular pressure plate (7) closes the upper end of the mould, while the lower end is closed partly by a stepped collar (5) (which shapes the inside of the pipe socket). This collar sits inside a ring (3) which shapes the face of the socket end of the pipe. After the concrete has been poured and consolidated, the mould sections are removed and the casting set aside to dry. After the cylindrical core and the socket-shaping collar have been removed, the casting can safely be lifted momentarily while the ring is removed and replaced by a plain board. The outer mould is then removed.

Title: Smoke detector using photocell responsive to reflected light - includes light source monitor and RC network connected to level detector (BR 19.7.77)
Inventor: DOHERTY WILLIAM F
IPC: G08B29/04
Filed: 1975-11-26
Abstract: The smoke detector comprises a housing defining a tortuous path between a light source (L) and a photocell (C1) so that the latter responds to light reflected or defracted by smoke particles. The electrical characteristics of the photocell (C1) are monitored by a device which supplies a corresponding signal to a voltage level detector (N), connected to a trigger circuit for an alarm (A) to operate the latter when the photocell indicates a given smoke concentration. An RC network (F1, R3) is connected to the level detector (N) followed by a pulse former, connected to the trigger device (SCR). A second photocell (C2) responds to the failure of the light source (L) to activate the pulse former.

Title: Reduction of monomer content of solid PVC - by heat treatment with exposure to dilute chlorine
Inventor: MIELKE INGOLF DR
IPC: C08F6/26
Filed: 1976-04-08
Abstract: Treatment f PVC powder contg. 57% Cl, or vinyl chloride copolymers by heating at 50-100 degrees C for >=10 mins. while in motion. During or after heating, the powder is treated with highly diluted chlorine (PCl2 is not >100 torr) in amount of >=10 ppm polymer, in absence of chlorination catalysts. Remaining chlorine is subsequently removed from the polymer. Pref. PCl2 is 0.01-10 (0.03-3) torr, mixed with an inert gas (air). Treatment is effected at 10-100 degrees (30-90 degrees) esp. 40-70 degrees C. More intensive heat-treatment to remove residual monomer is possible, without discolouration of the PVC. Chlorine content is not increased above 57%, and processing and application properties are not affected. The process can be carried out continuously, using simple, compact and cheap plant, esp. in the polymerisation reactor.

Title: Control voltage generator built into limiter - operates as series RC circuit grounding output and giving control volts across capacitor
Inventor: SAX HERBERT
IPC: H03G3/30
Filed: 1976-04-23
Abstract: The control voltage generator is built into a limiter and thereby avoids using extra circuits for generating a control voltage. The limiter output (A) is led to 'earth' via a resistor (R) and a capacitor (C) is series. The control voltage (Ust) is taken from across the capacitor. An indicator or instrument may be connected across the capacitor. In the case of multi-stage limiters, the d.c. voltage dependent on the input signal is derived from the capacitor in the Rc circuit that connects the output to the emitter of the input stage.
