Title: Fuse for a Rocket Projectile
IPC: F42C14/00
Filed: 1979-07-12
Abstract: Hitherto, an additional explosive charge or the pressure of the rocket propellant gases has been necessary for fuses in rocket projectiles in order to displace a detonator from its safety position into its armed position. In the fuse according to the invention, an inertial body 13, on firing of the rocket projectile, drives a retarding mechanism by its inertia. As soon as the retarding mechanism has run down, the detonator 32 can be displaced from its safety position into the armed position and can be secured there against further displacement. As shown, a spring 17 biases the body 13 and a carrier 24 for the detonator towards the unarmed position. During acceleration the body 13 is displaced rearwards and drives a flutter body 21 via a pinion 22 and gears to retard the displacement. When the pinion 22 has run down a rack 15, the body 13 is unrestrained and draws a stepped bolt 28 backwards to release locking bolts 30 and move the carrier 24 so that the detonator 24 is opposite a transfer charge 10. In this armed position the bolts 30 are held in grooves 38. <IMAGE>

Patent GB-2051878-A (GB)
Title: Heat-reflecting titanium dioxide coated glass panel.
IPC: F24S23/70
Filed: 1980-07-22
Abstract: A heat reflecting pane is formed by vacuum deposition and subsequent oxidation of a layer of titanium on a glass substrate to form an inner anatase layer and an outer rutile layer. The evaporation of the titanium is commenced at a pressure above 1 x 10<-4> Torr, with an oxygen pressure of 1 x 10<-4> and is conducted at such a rate that the pressure is reduced to about 10<-5> Torr. Hence the first deposited portion of the layer is grown under conditions which in subsequent oxidation give an anatase structure, and the later deposited portion of the layer develops a rutile structure. Deposition of the titanium layer is continuous and the resulting anatase layer has a continuous density increase in the direction away from the substrate. A second layer of titanium may be deposited over the initial layer, under similar conditions, so that a second pair of anatase and rutile layers are formed on oxidation. The pane may also be subjected to thermal prestressing simultaneously with or subsequent to the oxidation heating.

Title: Method for the measurement of consumption of energy and power
Inventor: TEITTINEN HEIKKI TAPIO
IPC: G01R21/00
Filed: 1982-06-30
Abstract: Described herein is a method for the measurement of consumption of energy and power, and particularly for the measurement of consumption of electrical energy and power. According to the invention the power to be measured is in advance divided into steps of power, an energy- measurement register (R1) of its own being assigned to each of these steps, whereby each register (R1 to Rn) is alternately allowed to measure and to register a predetermined value of energy consumption, whereupon the measurement is shifted to a next register. After a predetermined cycle of measurement the measurement is shifted back to the first register (R1) for the start of a new cycle of measurement. Hereby the readings of the different registers, after a desired number of measurement cycles, give an approximation of the cumulative power distribution curve.
