Title: Urine bottle for the bedridden - has partition forming two compartments preventing spillage through mouth
IPC: A61G9/00
Filed: 1973-07-25
Abstract: The bottle is divided into two compartments (b, f) by a partition, with a free passage at one end. This allows liquid from the mouth to accumulate in the lower compartment, where it is retained, even when the bottle is tilted, without the liquid escaping through the mouth again. The partition can be of concave profile, to assist liquid flowing from the top to the bottom compartment. The bottle is emptied by inverting it so that liquid can flow from the lower compartment, which is now above the partition, into the upper compartment and out of the opening.

Title: Mfr. of melted cheese in block form - with veins made from second cheese with different flavour and colour
IPC: A01J27/04
Filed: 1975-05-09
Abstract: New type of melted cheese, sold in the form of distinct blocks, is obtd. by preparing the usual paste of melted cheese and then preparing separately a second paste flavoured and/or coloured differently from the first. The usual paste is poured by successive doses into the mould and at the same time the second paste is injected into the first as it descends to the mould. A rotating drum dosing device allows of the periodic introduction of the second paste. This is delivered to the dosing device at 70 degrees C. As a result, the cheese which fills the mould shows pleasing, irregular veins and marbling effects due to the second cheese paste. Each mould may be rotated a quarter of a turn during filling so that the veins are drawn out slightly and given a helical appearance. The cheese obtd. has a characteristic, attractive appearance; the flavour as well as the colour can vary considerably. Fragments of nuts can also be added and the process can be operated on the industrial scale.

A separation circuit separates the virtual address into groups. An associative memory receives the second group and stores the addresses of the pages of the real memory, forwarding that which coincides with the address group. A calculation circuit connected to the associative memory calculates the sub-page address, in accordance with the third address group.

Title: Regulated power supply for TV receiver - has thyristor switching rectifier between full and half wave mode to isolate from mains
Inventor: DIETHELM OTTO
IPC: H04N5/63
Filed: 1976-04-07
Abstract: The regulated power supply, for a television receiver, rectifies the a.c. supply and uses a thyristor to stabilise the resulting d.c. voltage. The full wave rectifier bridge (2) has a second thyristor (7) connected into one arm in series with that arm's diode. This thyristor allows the full wave bridge to be switched over to half wave rectification. Changeover between gull and half wave operation occurs when the line output stage is building up. The advantage of the thyristor lies in its preventing interference passing back into the supply network since it isolates the power supply and the mains.

Title: Integrated electronic control circuit for central heating boilers - has two sections forming static contactor and temperature comparator
IPC: G05D23/24
Filed: 1976-06-09
Abstract: The electronic circuit for the control of a central heating system using hot water, is in two sections (12, 13). Section (12) is a triac regulating the operation, whilst section 13) forms the control circuit. When the thyristor (15) is energised, the voltage between point (18) and (21) is reduced and half periods are fed to the motor (17). The thyristor is energised when the temperature of the water is too low or too high. The control circuit is fed by a Zener diode (35) with a continuous trapezoidal voltage. Changes in temperature are detected by thermistor (24) in the bridge formed by resistances (32, 37, 38, 39). Resistances (38, 39) apply a reference voltage to point (40). If it is less than that at points (41, 42), the circuit trips.
