Title: Flying carousel lift system - incorporates trolleys on climbing rails to provide a climbing servo effect
Inventor: KASTNER HELMUT
IPC: A63G1/28
Filed: 1975-03-29
Abstract: The flying carousel consists of a frame which turns round a central mast. The outer rail of the frame forms a steep climbing rail for a trolley. The gondolas are fixed to swing arms which pass through ball bearing strikers in the trolleys so that the arms can move upwards and downwards but not slide outwards. The upper end of the arm is linked to a link lever which is fitted to the central mast. When the carousel is set in motion centrifugal force tends to force the gondolas outwards, making the trolley climb the steep rail. The height to which the gondola climbs is dependent on the speed at which the carousel revolves. This climbing motion can also be assisted by the incorporation of a compressed air system between the swing arm and/or the link lever and the central mast.

Title: Coagulating instrument with direct current heating element - has auxiliary supply maintaining constant total current in element
Inventor: SEMM KURT PROF DR MED
IPC: A61B17/00
Filed: 1975-07-12
Abstract: The coagulating instrument is used with an endoscope especially for hysteroscopy. It has a direct current heating element with visual and acoustic monitoring of the heating. As the element gets hotter the monitoring tone frequency increases until a constant frequency denotes constant heating temperature. The time period from start of heating until end of the uniform heating period for coagulation can be selected and monitored by a time switch. A transistored current constant regulator and an operations amplifier with a transistor and resistances and a temperature regulator with diode and amplifier regulate the auxiliary current to the heating element. This is heated separately by a 5-volt source across the diode and resistance. The total current in the heating element is kept constant as the temperature is adjusted with the control resistance.

Title: Security device for monitoring vertical plane - uses infrared beams criss crossing vertical plane with transmitter on vertical chassis and column of receivers
Inventor: NEUBERT WALTER
IPC: F16P3/14
Filed: 1975-09-12
Abstract: The security device is for protecting a vertical plane against intrusion and uses a simple arrangement of infrared beams criss-crossing the plane, which can typically be several hundred metres broad, and of more than a mans height. The system uses only two infrared sources. The device represents a simplification of similar equipment which uses many transmitters and receivers. It consists of a transmitter (3) mounted on a vertical chassis with a column of receivers (4) at one end of the plane and a similar arrangement (7, 8) at the other. Each transmitter excites all the receivers at the opposite end of the plane and these feed an AND gate (10, 13) in each case, which in turn excites the local transmitter. The system operates in a pulsed manner so that the interruption of any beam stops the local transmitter and triggers an alarm circuit.

Title: Valve tray in mass transfer columns to prevent spray carry over - has plate attached to the valve below the tray
Inventor: HILLER HANS
IPC: B01D3/16
Filed: 1976-10-29
Abstract: Valve tray is for mass transfer columns where vapour is flowing up the column and liquor down. The tray has a number of openings in it in which are located coverplates with guides to limit their movement and prevent them moving out. The coverplates are located below the level of the tray. Crossed arms can be attached to the plate arranged at right angles to each other in the form of two plates rising vertically from the cover plate. The cover plate is of greater dia. than the opening. The cross plates have protrusions which prevent the valve from dropping through the opening. Used in gas/liquid mass transfer operations e.g. absorption or distillation. Liq. cannot be carried over from one tray to the next by the vapour stream. This improves the tray efficiency and thus the overall efficiency of operation and the capacity of the column.
