Title: Disc separator for automatic record player - has thin sheath placed between discs to prevent damage and eliminate speed slip
Inventor: GORDON ROBIN A DR
IPC: G11B17/02
Filed: 1976-06-29
Abstract: The disc separator is for automatic record players for insertion between the stacked records having a central part of very thin elastic sheath and three arms coated with rubber or equivalent material. This is for use with automatic record players in which the discs are released in sequence from the stack to drop to the turntable on top of the disc already in position. The use of the separator prevents damage to the record already in position by the edge of the oncoming disc, and ensures absence of slip between the upper disc and that below through which it is driven.

Title: Explosion proof terminal box for mines - facilitates handling with extended corner lugs for crane hook at its back
Inventor: HIDDE DIETER
IPC: H02B1/28
Filed: 1976-06-25
Abstract: The explosion proof terminal box for switchgear in mines forms part of concept underground stations, and the design ensures easy manipulation of the heavy structure.

Title: Pressure converter with balance beam - has pressure membrane acting through lever system to allow beam adjustment
Inventor: WEISS RICHARD
IPC: G01L11/00
Filed: 1976-12-22
Abstract: The pressure converted has a balance beam, charged on one side by a force proportional to the input measured value. The other side of the beam has a nozzle bafle plate arrangement to produce a pneumatic output pressure proportional to the measured value. The output pressure is fed to a pressure membrane, charging the balance beam opposite to the measured value via a lever arrangement, which allows adjustment of the active lever arm of the beam, and thus the conversion ratio. The measured input value (Pe) also acts onto the beam (1) via a lever system (14). This system allows the adjustment of the beam lever arm on the input side.

Patent DE-2756298-A1 (DE)
Inventor: NABHOLZ HANS-ULRICH DR
IPC: F26B5/04
Filed: 1977-12-16
Abstract: In the case of a condensation heating device, which operates with an highly volatile fluid, for example kerosene, in a vacuum, the insulation of electrical apparatuses or of their parts, such as transformers, capacitors and the like, is dried and degassed in a known manner, the slightly volatile impregnation fluid, for example insulating oil, at the same time being flushed out of the insulation and being mixed with the highly volatile fluid. The device has a separating device (4) which is split into two stages (41, 42) and in which the oil is separated from the kerosene/oil mixture which is produced. A fluid partial flow of the kerosene/oil mixture is fed through a supply line (g) from the main evaporator (3) to the first stage (41) in which the intention is to achieve only a preconcentration of the oil by vaporising the highly volatile fluid, no vaporisation-energy losses occurring, since the vapour flow is fed to the autoclave (1). A predetermined quantity of the accumulating kerosene/oil mixture is fed from the first stage (41) through a supply line (h), which has a flow regulator (11), to the second stage (42), which operates at a lower pressure, the vaporisation energy of the second stage (42) in this case being lost for the actual drying process. <IMAGE>
