Title: Making open-ended concrete building unit in re-usable shuttering - by removing vertical shuttering from partially set and supported unit
IPC: B28B7/22
Filed: 1973-12-12
Abstract: The building unit (1) is cast with floor, ceiling and two side walls in a vertical position and supported on a base (6). After the concrete has partially set, the internal shuttering (3) is removed and the external shuttering (4) opened on one side thus permitting the unit to be moved for storage and final hardening on its base. As an alternative the unit is released from internal and external shuttering and lifted on its base to a level above that of the shuttering, then moved sideways and stored. The internal shuttering is preferably provided with resilient fillers (5) in the sides to absorb shrinkage and, after removal of the fillers, to facilitate removal of the internal shuttering.

Title: Paraffin coated cheese packed in stretch foil - giving better appearance and greater protection for the paraffin layer
IPC: B65B53/00
Filed: 1974-10-21
Abstract: A paraffin-coated cheese is packed in a stratch-foil. The appearance of the cheese is better than when it is wrapped in 'Cellophane' (RTM); the top and sides of the cheese have a smooth, clear film, with folds only under the cheese. The film gives better protection to the paraffin layer than does 'Cellophane', and the paraffin does not crack. There is less alteration in the shape of the cheese, e.g. an Edam cheese showed a difference in height of only 2cm during a storage test. Claimed films are soft PVCM polypropylene or polyethylene films. The cheese can be wrapped by hand, in the appts. used for packing in 'Cellophane', or in an appts. with a conveyor belt of capacity such that it can run in combination with the appts. for applying the paraffin.

Title: Temp. regulator for gas or liq. pipeline - maintains constant temp. when measuring vol. of fluid loaded or delivered from tanks
IPC: G01F15/02
Filed: 1981-10-22
Abstract: When tankers are loaded with liquids or gases and the load is measured volumetrically, errors can arise because of expansion of contraction due to temp. differences. This device heats or cools the fluid so that loading and delivery can be made at the same constant temp. The temp. of the fluid is monitored as it enters a housing containing a heating element and a cooling fan. It flows through a ribbed pipe where its temp. is brought to the required level before it is measured by a volumetric measuring device.

Title: Self-checking blood alcohol monitoring aid - shows alcohol content as function of elapsed time, number of drinks and body wt.
IPC: G06G1/00
Filed: 1982-07-06
Abstract: The accessory is intended for checking the blood alcohol content with reference to the time elapsed since taking the first alcoholic drink, the number of drinks consumed, and the body weight. It is based on the assumption that approximately equal amounts of alcohol are contained in drinks of different strengths and that the breakdown rate is a standard function of body weight. It comprises two elements, e.g. a sleeve containing a disc rotatable to show one of a number of sets of figures in a window of the sleeve. By the side of the window, the sleeve shows elapsed times whilst each radial set of figures shows body weight (e.g. 65 kg), number of drinks consumed, and parts per thousand (e.g. 1.25-0.20) blood alcohol content related to the respective elapsed times. Used for self-monitoring blood alcohol content to determine legal fitness for driving. The accessory is a useful aid in avoiding driving with blood alcohol above the legal limit.

Patent NL-8901255-A (NL)
IPC: G06F12/08
Filed: 1989-05-19
Abstract: A microcomputer system includes a microprocessor, a cache memroy, and a cache controller all coupled to a local bus. The local bus is coupled to a sytem bus, connecting the remaining system components, through latches. When writing data, the microcomputer can perform a posted write to a unit on the system bus by writing the data into the latches and then, on receipt of a ready signal from the cache controller, continuing its operations without waiting for the data to pas to its destination. A problem arises if the data is posted to a unit with a data width less than that of the microprocessor. In this case, the data should be sent in multiple cycles, but the read signal is generated before the data width of the unit is known and the microprocessor then continues its operations and can not, therefore, transmit the data correctly. To solve this problem, a logic unit is added to monitor the ready signal and the output of a decoder which detects non-cacheable addresses (which are of data width different from the microprocessor data width). If a non-cacheable address is detected, the read signal from the cache controller through the logic unit is withheld from the microprocessor, which now waits to continue processing beyond the write until a ready signal is received from the addressed unit on the system bus.

Date Dec. 26, 1991.An interactive communication and transport system in which communication for the purpose of requests takes place between requesting receiving stations (B) and one or more request-processing transmitting stations (A) provided with a source (1-4) of information of separately specifiable bulk data (including picture data) via a relatively low-speed communication path in a first network (6), and the forwarding of the requested bulk data to receiving stations (B) specified in the requests by transmitting devices (14-17) takes place in a packet-switched mode via a relatively high-speed transmission path in a second network (10). Temporary destination addresses are assigned to the receiving stations (B) for the forwarding, and permission is granted for forwarding to the transmitting workstations (A) on request. The actual forwarding of data takes place after a respective transmitting station (A), which has received permission, has detected, by an "end of packet" detector (18), that transmission of a previous packet has been completed. The data channel along which picture data is transported is thus used more efficiently, and forwarding of picture data to a group of destinations is possible both on request and dynamically from the system.
