Title: Solderless joint for pipes of central heating systems - has plastic muff secured to pipes with adhesive and provided with rubber sleeve in enlarged central bore
IPC: F16L13/10
Filed: 1975-08-22
Abstract: The plastic muff has an enlarged central bore which houses a rubber sleeve. The rubber sleeve has a central rib which forms an abutment and a seal for the tubes. The tubes are then secured with adhesive in the bores to form a leak-proof joint. The system is intended primarily for central heating systems but can be adapted for higher pressures by fitting a stainless steel tube in the enlarged bore which encloses the rubber sleeve. The joint can also be used with corrosive fluids by lining the pipes with plastic liners.

Title: Quality control system for production machine - records signal representing each defective item tested with spacing between signals indicating quality
Inventor: BERTHOU JEAN
IPC: G07C3/14
Filed: 1976-05-10
Abstract: The quality control system, used for a high-speed production machine, has each nth item produced by the machine checked, where n is any positive integer. A signal is produced each time the item being checked is defective, with these signals recorded so that the spacing between the recorded signals represents the number of non-defective items between the defective items. The recorded signals are read each time a given number of items have been produced by the machine. A reversible counter may store the number of signals recorded, with means for dividing the count value by the number of articles produced before read-out.
Patent FR-2351173-A1 (FR)
Title: Sugar mfr. by crystallising and centrifuging - with heating of massecuite before centrifuging to improve crystal yield
IPC: C13B30/06
Filed: 1976-05-10
Abstract: Supersatd. massecuite is cooled in downflow crystallisers and then sepd. by centrifuging. Between crystallisation and centrifuging, the massecuite is subjected to a slow, progressive heating. This reduces the compactness of the massecuite and so facilitates different centrifuging without even partial remelting of the crystals during heating. The heating pref. takes place in a vertical, cylindrical vessel in which the massecuite rises countercurrent to a descending flow of a heating fluid, e.g., in a spiral coil. The temp. differential between the massecuite and the heating fluid is pref. 5 degrees C.

Title: Refractory concrete for cement kilns - produced from crushed spent stones from glass melting tanks, high alumina cement and active alumina
IPC: C04B35/106
Filed: 1976-07-23
Abstract: Hydraulically-bound refractory concrete contg. a filler with addition of 5-17 wt.% of high-alumina cement and an active alumina additive is improved in that the filler consists of crushed (6.3 mm), spent stones from glass-melting tanks (fused ZrO2-Al2O3-SiO2); the filler is used in an amt. of 55-90 wt.% w.r.t. the whole compsn. This refractory concrete is esp. suitable for the construction of kilns for cement firing. The crushed stones from glass-melting tanks contain some adhering glass whereby the concrete acquires high abrasion resistance, esp. in the range 700-1200 degrees C. which is important for cement-firing. The utilisation of wastes greatly reduces the price of the refractory concrete.

Title: Float glass forming process - transferring glass strip from metal bath to gas cushion at controlled temp.
Inventor: GLIKMAN MARK LEONOVICH
IPC: C03B35/24
Filed: 1976-12-29
Abstract: In a float glass forming process in which an inductor maintains the level of the molten metal at the outlet end above the top edge of the end wall, the formed glass strip is rectilinearly transferred at 650-700 degrees C from the molten metal to a gas cushion for further cooling. No oxide formation occurs at the transfer temp. and the glass strip is sufficiently stiff to avoid contact of its lower face with the gas cushion forming appts. Increased prodn. rates are also possible.

Title: Differential protection system guarding against equipment faults - removes need for insertion of test resistance loads using variable LV generator
IPC: H02H3/04
Filed: 1977-02-02
Abstract: A control circuit (1) for units is designed to provide protection against faults in equipment which are signalled by differential changes in current. The circuit removes the need to insert resistors in the control lines of the equipment depending on the sensitivity expected to check its correct functioning and the need to power the associated cut-out switch. The circuit has a generator providing a variable low level voltage corresponding approximately to that of the power supply and having a frequency slightly higher than this supply. Current drawn is displayed, this unit being fed from a memory. The generator is controlled from a reference source which is dependent on the current drawn.

Title: Platform for offshore petroleum installation - mounted off-centre in relation to tower and partly supported by pillars, reducing weight and base dimensions
Inventor: BONIN JEAN-PIERRE FERDINAND FE
IPC: E02B17/02
Filed: 1977-02-18
Abstract: A monopedal structure comprises an infrastructure, a tower and a superstructure. The infra-structure rests on the sea-bed and consists of an apron and ballasting and storage capacities. The tower supports the superstructure which consists of a platform on which are the drilling equipment, the treatment works and the living quarters. The drilling equipment occupies a part away from the treatment plant and the living quarters. A part of the platform is supported by pillars, the platform being off-centre in relation to the tower. The part occupied by the drilling equipment is vertically over the tower, while the part occupied by the treatment works and the living quarters is supported by the pillars, which bear on the base. The tower contains a water-tight shaft offset with respect to its axis. The decentralising of the shaft and the platform in relation to the tower allow the dia. of the tower to be reduced while its drilling capacity is retained, and combines the advantages of monopedal and columned structures. It is structurally sound and rigid.
