Title: Luggage rack for cycles and motor cycles - is rigidly supported at three points on mud guard and foot rests
IPC: B62J7/04
Filed: 1973-06-13

Title: Animal organ perfusion life extended by higher temp. flushing - which prevents vasoconstriction so that blood is washed out
IPC: A01N1/02
Filed: 1973-06-29
Abstract: An animal organ to be kept alive by continuous perfusion (e.g. human kidney) after isolation from its body is first washed through with a suitable soln. at 10-15 degrees C. Under pulsating pressure surges and then immersed, at rest, in a soln. at 0-1 degree C. By using a flushing soln. at 10-15 degrees instead of the much lower temp. employed in previous techniques, any considerable vasoconstriction of blood capillaries is avoided so that blood is completely removed by pulsating surges of flushing soln. and the organ can be kept alive for a much longer period.
Patent FR-2237358-A1 (FR)
Title: Angularly modulated carrier oscillation demodulator - for video disc reading involves using limiter differential amplifier
IPC: G11B7/00
Filed: 1973-07-13
Abstract: A demodulator of an angularly modulated carrier oscillation for use as optical reader of the record on a video disc can filter the signal produced without interference with the upper frequency of the modulation signal band. The signal, applied to the terminal of the differential amplifier is generated by shifting a signal in a delay line by a fixed amount; the latter is so designed that the zero passages can be defined more accurately. This is achieved by connecting the negative input by a connection to the delay line input, and the output of the delay line to the positive input.

Title: Central heating system boiler - has manual changeover switch for thermostats in primary and secondary water flows to control burner
IPC: F24H9/20
Filed: 1975-09-26
Abstract: A hot water boiler has a burner with a control box. A calorifier for secondary hot water is built in as part of the unit. The primary water circulates through a heating jacket round the calorifier by gravity and is circulated to a heating system by a pump. When heating is required, the burner is switched on and off through the control box by a thermostat in the primary water flow. A thermostat in the secondary side of the calorifier is also connected to the control box. At times when heating is not required, a manual changeover switch puts the burner under the control of the secondary water thermostat and the primary thermostat then functions as a high limit control.
Patent FR-2326261-A1 (FR)
Title: Tilt hoist for ladles used in casting metals - where ladle can only be raised or lowered when it is vertical
IPC: B22D37/00
Filed: 1975-10-01
Abstract: Casting device which includes a ladle hinged on its spout and located on two trunnions at the bottom end of a fork mounted in a stirrup which can slide in a chassis moved along a guide rail. A hoist is mounted on the chassis with a chain via which both the stirrup and the fork are suspended; the chassis is also provided with a control handle for moving the fork and also for clamping the stirrup to the chassis so the ladle can be tilted and moved vertically. The novelty is that at the outlet of the hoist, the chain passes round a pully fixed on the stirrup and then round a second pulley fixed on the chassis before the end of the chain is fixed by a hook onto the fork. Further pulleys may be used for the stirrup and the fork, but always a larger number for the stirrup. The ladle can only be raised or lowered when it is in a vertical position, i.e. not titled. This prevents agitation of the metal and avoids serious accidents which could arise due to metal falling unexpectedly out of the ladle.
