Title: The baking of bread and the like dough products
Inventor: MARTIN ALAN
IPC: A21D6/00
Filed: 1988-08-30
Abstract: In a process for baking bread and the like, the bread is heated to a temperature between 40 DEG C and 50 DEG C in a final prover (14) before transfer to a travelling oven (15). The latter has no static/development section. The higher than conventional entry temperature into the oven reduces the difference between the near-crust temperature and the core temperature, thereby enabling the industry-prescribed core temperature of 96 DEG C to be reached in 12 to 17 minutes. The shorter bake time reduces the weight loss and the weight loss spread, enabling a lower weight dough piece to be used to produce a loaf of a desired weight, e.g. 800g. <IMAGE>
Patent GB-887612-A (GB)
Abstract: 887,612. Ticket-issuing machines. LICENTIA PATENT - VERWALTUNGS - G.m.b.H. Dec. 29, 1959 [Jan. 2, 1959], No. 44101/59. Class 106 (3). A ticket-printing and issuing machine has a printing cylinder 2 which is held by a detent 35 in the rest position and which has adjustable type wheels 19 which are set by means of levers 14 through segments 15 and setting wheels 17 and the ticket is issued by a rotary printing process through a crank 29 and gear-wheels 30, 31 for driving the cylinder 2 when it is released and the setting wheels 17 and type wheels 19 are previously disengaged, the drive to the cylinder 2 being so arranged that, in the course of a single movement it first effects the disengagement of the setting wheels 17 and the printing cylinder 2, releases the cylinder 2 and finally drives the cylinder 2 for a printing operation. The setting levers 14 and segments 15 are carried by a frame 10, which can be pivoted about a shaft 12 against a torsion spring 12, but which is prevented from pivoting during setting by a pin 37 engaging an arm 36, and which carries the detent roller 35 engaging a notch in the cylinder 2. The gear-wheels 30, 31 with transmission ratio 2: 1 have twenty and thirty-eight teeth respectively. Two teeth 38 of wheel 30 and one tooth 40 of wheel 31 are of half thickness and so pass one another freely and there is a tooth missing each side of tooth 40. Thus, lost-motion is provided between the wheels 30, 31 so that at the beginning of a rotation of the crank handle a cam plate 32 can rock a lever 33, and lift the detent 35 and frame 10, disengaging the setting mechanism and freeing the cylinder 2 for rotation during the remainder of two turns of the crank. While the detent 35 engages the cylinder 2, detent rings 18 hold the wheels 17 to a limited extent whilst allowing setting movements, but lifting the detent 35 and frame 10 locks the wheels 17. Levers 43 pivoted on the frame 10 carry a pin 42 passing through all the rings 18 and while the levers 43 can rock past a knife edge stop 46, the pin 42 allows the detent rings to move against their springs 47, but when the frame 10 raises the levers 43 so that the stop 46 prevents them turning, the pin 42 clamps the rings 18, thus locking the wheels 17.

Title: Control device for switched power supply
Inventor: BUISSON JEAN-MICHEL
IPC: H02M3/157
Filed: 1990-01-18
Abstract: The device is designed to give a signal for the control of the ballast signal of a switched supply by using an index value signal (Vb). To benefit from the advantages of a digital control, the control signal is prepared as a function ot logic values, pre-programmed in an encoding memory (11, 12). The value of the index value signal at a given instant defines a starting and an ending of a zone in the encoding memory (11, 12), and the cyclical reading of this zone through reading means (13) gives the control signal (Vc). The supply is switched by means of a transistor (2, Fig 1). <IMAGE>
Patent GB-2231524-A (GB)
Title: Metal and ceramic-substrate bonding
Inventor: HYDE ANDREW RICHARD
IPC: H05K3/38
Filed: 1990-02-15
Abstract: A method of bonding a layer of metal to a ceramic substrate, particularly say, copper to alumina or zirconia, in which the substrate or the metal or both are coated with a solution of oxygen-rich metal salt, eg. copper perchlorate or copper nitrate. The copper layer is assembled to the alumina with the intervening coating and the assembly heated in an inert atmosphere. The copper salt breaks down at about 600 DEG  to 700 DEG C leaving a deposit of copper oxide on the ceramic and releasing oxygen which oxidises the copper layer. The two layers of copper oxide then amalgamate in a common melt and provide a firm bond. This method provides a controllable local oxidising atmosphere at the contacting surfaces while the whole assembly is maintained in an inert atmosphere. The salt is preferably a salt of the same metal as the metal which is being bonded. The bonding of the metal to the ceramic substrate may be followed by etching of the metal to produce electric circuitry.

Title: Vacuum toilet system
Inventor: TERVE ROLF
IPC: E03D5/00
Filed: 1991-04-19
Abstract: A vacuum toilet system comprises a number of toilets each of which is connected to a sewage collecting tank (5) through a normally closed sewer valve (2) and a sewer pipe (3) in open connection with the tank. Vacuum generating means create a partial vacuum in the tank (5) and the sewer pipe (3), when a toilet emptying is initiated and this vacuum is of a magnitude providing effective transport of sewage from any of the toilets to the tank. The operating time of the vacuum creating means is kept substantially constant for each toilet emptying cycle, thereby creating a partial vacuum level that varies in response to the total free volume present above the liquid surface in the tank (5) and in the sewer pipe or pipes (3). This vacuum level variation provides an optimum vacuum level that is by itself properly adapted to the total free volume of the sewer pipes (3) and the collecting tank (5). <IMAGE>
