Abstract: 1,190,216. Rocket engines. BÍLKOW G.m.b.H. Nov.6, 1967 [Nov.11, 1966], No.50440/67. Heading F1J. The invention relates to a liquid rocket unit of the kind having a preliminary combustion chamber the gases from which are directed on to an axialflow turbine which is utilized for driving auxiliary units, the gases discharging from the turbine passing into the main combustion chamber which is disposed downstream of the preliminary chamber. The downstream face of the turbine rotor disc is protected from the heat in the main combustion chamber by a heat shield which is of double-wall construction for the flow of coolant in the form of liquid propellant therethrough, the propellant discharging from the heat shield radially outwardly into the stream of hot gases discharging from the turbine. A further quantity of propellant is injected radially inwardly into the stream of exhaust gases from the turbine through injection devices mounted on the wall of the main combustion chamber. In the embodiment shown, the preliminary combustion chamber is indicated at 1 and the main combustion chamber at 4, a turbine 3 having blades 3a being disposed so that the combustion gases G from the preliminary chamber act on the turbine blades 3a and then discharge into the main chamber as indicated by arrows Ga.

In a method of permanent waving, a tress of hair, wetted with waving lotion, is laid on an elastic, mat-like body, e.g. of synthetic plastics, rolled therewith, and secured by a transfixing pin while the lotion reacts with the keratin of the hair. The pin is then loosened so that the body and hair partially unwind to a larger diameter and are resecured by the pin for setting, rinsing and drying of the hair. In modifications the securing means consists of a rubber ring or rings extending longitudinally or laterally of the wound body, snap-engaging projections and apertures, or a flexible, non-resilient wire, e.g. of synthetic plastics extending from one end of the body and bent around the rolled body. A longitudinal or lateral projection may be formed on the body to be folded over the tip of the tress, or a rubber ring may be provided, to aid rolling of the tress. In further modifications the body tapers in thickness towards the longitudinal centre, the size of the perforations varies, or the body is made of a permeable material and has a lining of silica gel.

Title: Automatic drainage of liquid from pressurised gas systems
IPC: F04B39/16
Filed: 1971-11-02
Abstract: 1360405 Fluid-pressure servomotor systems JOY Mfg CO 2 Nov 1971 50940/71 Heading G3P [Also in Division F1] In compressed gas, steam or distillation systems wherein collected condensate 11 has to be drained through a passage 13, 17, 22, 25 with the minimum loss of the gaseous fluid above the condensate, a periodically opened drain valve 14 is closed in response to the change in pressure which occurs in a chamber 21 when gas instead of condensate flows therethrough. The pressure change occurs in the chamber 21 as a result of restricted orifices 18, 19 disposed, respectively, in the inlet and outlet lines 17, 22 of the chamber 21, the orifice 19 being of equal or greater area than the orifice 18. In the embodiment shown the valve 14 is fluid controlled but it may be controlled by an electric circuit, Figs. 3 and 6 (not shown) which circuit includes a pressure switch operable when pressure rises in the chamber 21. Periodic opening of the valve 14 is caused by a timer which moves a valve 30 to a position connecting a pressure source 32 to a line 28, 24 thereby to act on a diaphragm 16 and open the valve 14. When pressure rises in the chamber 21 due to the commencement of gas flow, this pressure acting through a line 23 lifts a spool 27, Fig. 2, against the bias of a spring 37. The line 24 is therefore exhausted through a passageway 42 whereby the valve 14 closes. The lifting of the spool 27 also causes pressurization of a chamber 36 via a spool passage 38 and a branch pressure line 28' so that the spool is held in its lifted position. Hence, when the pressure falls in the chamber 21 because of the closure of the valve 14, the spool remains lifted until the timer returns the valve 30 to its original position. A system for draining condensate from between the stages of a four-stage compressor is described, the system utilizing a single chamber 21 for controlling the drain valves of a pair of drain lines.
