Patent GB-957521-A (GB)
IPC: A21C1/14
Abstract: 957,521. Mixing by compression. AMERICAN MACHINE & FOUNDRY CO. Aug. 17, 1960 [Aug;-26, 1959], No.28567/60 Heading B1C. [Also in Divisions B5 and F1] A dough developer, shaper and divider has an elongated chamber 50 shaped in crosssection as two spaced arcs connected by tangential sides, and two counter-rotating paddles 44, 44<SP>1</SP>, the centres 44a, 44a<SP>1</SP> of whose crosssections are eccentric to the centres 50a, 50a<SP>1</SP> of the arcs. There is an inlet 64 at one side and at the rear of the chamber, and an outlet slot 70 in the bottom and front of the chamber. As shown, the paddle cross-sections consist of two intersecting arcs with rounded tips ; they may be elliptical. The paddles are 90 degrees out of phase. Dough is supplied under pressure at such a rate that the chamber is completely filled; a back pressure is created in the chamber by the restricted outlet 70 aided by the pumping action of the paddles. A heat exchange medium may be supplied to a jacket 36 surrounding the chamber, and through ducts 60, 62 in the shafts 42, 42<SP>1</SP> to chambers 54-57 in the interior of the paddles. The machine has a stretching, compressing and shearing action on the dough. The dough passes to a shaper throat 72 the cross-section of which may be varied by means of a lug 76 swinging on pins as at 79 and adjusted by knob 92. The dough is there expanded, and then compressed to pass through a delivery duct 80 which is however of larger cross-section than the opening 70. There may be a knife 82 mounted on an endless chain 84 to separate discrete portions of dough which are received in the baking pans 88 the intermittent movements of which are co-ordinated with those of the knife.

Patent GB-2307509-A (GB)
Title: Spring band clip
Inventor: BEICHT BERND
IPC: F16L33/10
Filed: 1996-11-18
Abstract: A spring band clamp has two end portions (11, 12) with abutment jaws (13, 14) which project beyond the clamp periphery, for opening the spring band clamp. The abutment jaws (13, 14) extend approximately tangentially to the spring band (10) which can exert a closing force component which is directed in the peripheral direction and which in the opened condition of the spring band clamp is greater than in the operative condition. When the spring band clamp is open a tongue (17) which is pressed out of the end portion (11) bears under the closing spring force component by a support means (18) against a support surface (19) which is inclined at an angle (A) to a radius (R) of the clamp, at the free end of the abutment jaw (14) of the other end portion (12). The support means (18) and the support surface (19) can be brought out of contact by a radial relative movement of the end portions (11, 12). To simply production of the spring band clamp and to prevent closure of the pre-opened spring band clamp by accidentally applied forces, the support means (18) is formed by a radially inner edge of the free end surface of the tongue (17), wherein said radius (R) defining said angle (A) is tangential to a radially inner edge (21) of the support surface (19).

Title: Smoothing shift in an automatic gearbox using engine torque reduction
Inventor: WAGNER THOMAS
IPC: B60W30/18
Filed: 1996-11-29
Abstract: In order to increase the gear shift comfort during a gear-shift procedure, engine-torque reduction is started at the earliest when the freewheel point of the gearbox is reached, when a clutch asscociated with the old ratio has disengaged, and is ended shortly before the synchronisation point of the gearbox is reached (the new ratio fully engaged). The freewheel point and synchronisation point of the gearbox are established by determining the speed differentials between the input and output sides of the gear-shift elements, e.g. clutches, which participate in the respective gear-shift procedure. These may be measured directly or deduced from the gear ratios and measurements of the input and output shaft speeds. The differential speed thresholds which are used and the intensity of the engine-torque reduction are established using fuzzy logic systems.

Title: Inflatable articles such as life jackets
Inventor: MALE ANTHONY
IPC: B63C9/125
Filed: 1997-06-18
Abstract: An inflatable article, in particular a life jacket, is constructed from an outer carcass 38, which is made from tough textile fabric sections secured together to form the jacket profile for fitting the user, and to provide the inflation, rather than making the carcass inflatable, which is difficult, a separate inflation balloon 32 is used inside the jacket. The balloon can be of a simple geometric shape such as a cylinder, and non-load bearing, but which will take up the appropriate shape of the jacket when inflated, which is a different shape compared to that which it would take up when inflated unrestrained.

Title: Pedal locking device for a loader vehicle
Inventor: BEOM JIN SEOK
IPC: B60R21/00
Filed: 1998-07-24
Abstract: The loader includes a vehicle body with a cab 18 and a seat 16, and hydraulically operated working implements, eg boom, bucket and attachment, which are controlled via a hydraulic control valve unit 24 operated by respective pedals 26,28,30. A seat bar 34 swings between a lowered position in which an operator is secured to the seat 16 and a raised position in which the operator is released from the seat.

The all-oil fluid further comprises an organophillic clay (hectorite, bentonite and mixtures thereof). Optionally a surfactant that behaves as an emulsifier and a wetting agent, and a weighting agent (calcium carbonate, barite, hematite and mixtures thereof) are included. Suitable emulsifiers and wetting agents include surfactants, ionic surfactants such as fatty acids, amines, amides and organic sulphonates, and mixtures of any of these with non-ionic surfactants such as ethoxylated surfactants. The water-in-oil emulsion may consist of an oil phase, a water phase (salt or fresh), a surfactant, a weighting agent and salts or electrolytes.

Patent GB-988100-A (GB)
IPC: H02M7/06
Abstract: 988,100. Battery charging circuits; electric currents converting. GLOBE-UNION Inc. Feb. 8, 1962, No. 4916/62. Headings H2F and H2H. To equalize the currents in parallel loads 22, 24, which may be batteries, fed from a common rectifier 12, a 1 : 1 transformer having opposing windings 38, 40 is inserted in series with each load. Rectifiers 44, 46 prevent current circulating between the loads. A higher current in one winding induces a flux in the transformer core which tends to reduce the higher current and increase the other current. An excessive inequality between the currents causes a relay 48 to open the circuit through another relay 52 which illuminates a warning lamp 54. In another arrangement (Fig. 2, not shown), the rectifiers 44, 46 are incorporated with rectifiers 12 in a six-arm bridge.

Title: Wrap-spring clutch for vehicle driveline
Inventor: ORLAMUENDER ANDREAS
IPC: F16D41/20
Filed: 1999-01-21
Abstract: A spring clutch (10) in the driveline of a motor vehicle comprises a first input component (12) able to rotate about an axis of rotation (A), and a second output component (30) able to rotate about the same axis of rotation (A). The input component (12) is preferably drivably connected to a crankshaft of an engine and the output component (30) to a transmission input shaft. A coil spring arrangement (44), is retained in a non-rotary manner on the first component (12). The spring arrangement (44) extends around peripheral surfaces (39, 41) of the components (12, 30) and has a first section acting on the peripheral surface (39) of the first component (12) and a second section acting on the peripheral surface (41) of the second component (30). To release the clutch a rotary thrust bearing (86) displaces an actuating member (70) which partly rotates a disengaging member such as a ring (50) or a lever. The disengaging member (50) acts on the two spring sections to release these from engagement with the peripheral surfaces (39, 41). The clutch may include a torsional vibration damper.
