Title: Injection moulding foamed plastics articles - by filling cavity with pressurised medium, injecting plastics material applying with further medium against wall to form skin
Inventor: JARAUSCH HANS
IPC: B29C44/04
Filed: 1976-12-07
Abstract: Foamed plastics articles are injection moulded in a mould filled with a compressed gaseous medium whose pressure lies above the foaming pressure but below the injection pressure. An injection nozzle is introduced into the mould cavity such that its front face is flush with the wall of the cavity during the whole injection cycle, whilst an injection piston mounted slidably in the nozzle is displaced into the cavity to inject a predetermined amt. of the thermoplastics matl. into the cavity through a co-axial bore and radial ducts. The matl. is applied against the mould wall progressively by introducing pressurised medium into the matl. through radial openings to form a bladder whose pressure is equal to or greater than the pressure of the medium in the mould and greater than the foaming pressure. Following application of the matl. against the wall and cooling of the matl. to provide a homogeneous skin, the mould cavity is pressure relieved and connected to partial vacuum to enable the matl. to foam and form the foamed core; and finally the piston is retracted and the residual cavity filled with additional matl. Articles having a glossy, homogeneous skin and a foamed, cellular core are formed. Waste matl. caused by sprues is eliminated.

Title: Function tester for ultrasonic intruder alarms - produces simulated Doppler frequency shift and RC network to render phase-locked loop unstable
Inventor: NOVOTNY MILOSLAV DIPL ING
IPC: G01S15/52
Filed: 1977-03-31
Abstract: The operational check system for ultrasonic intruder alarms consists of a variable-frequency oscillator which normally drives an ultrasonic transmitter at a given, fixed frequency. This frequency is also fed to a frequency comparator on the output of the Doppler receiver. The function tester, when operated, causes the oscillator to deliver a frequency to the comparator which varies from the normal reference frequency used to drive the transmitter. The comparator reacts to an apparant frequency difference in the same way as it would if a Doppler frequency shift had occurred and triggers the alarm. The main alarm cuicuit, however, is not activated but a secondary indicating is energised to show that the equipment is operating correctly.
