Patent GB-493224-A (GB)
Title: Method of manufacturing fruit vinegar
IPC: C12J1/00
Filed: 1937-06-11
Abstract: Fruit juices are fermented and acetified to fruit vinegar having a concentration higher than the usual 5 per cent acetic acid, by increasing the sugar content of the juices by any method not involving the addition of large amounts of "foreign" sugar (e.g. beet, cane or starch sugar), or by increasing the alcohol content of the fermented juice by the elimination of water.  The sugar content of the juices may be increased by concentrating them by evaporation, or spraying, or freezing-out water, or by introducing natural fruit sugar as, e.g. concentrated juice or dried fruits or by making a mash of dried fruit with limited quantities of water.  The alcohol content may be increased by freezing out or by setting a juice of low sugar content into fermentation and adding a regulated amount of concentrated juice or by adding to a fruit wine of low alcohol content, a regulated amount of concentrated juice and refermenting. A fruit juice may be concentrated to such an extent that its sugar content acts as a preservative and diluted before fermentation.

Title: Vehicle driving arrangement comprising a fuel-injection internal combustion engine and a hydrodynamic coupling or converter
IPC: F16H63/30
Filed: 1976-04-22
Abstract: 1535861 Vehicle control apparatus DAIMLER-BENZ AG 22 April 1976 [24 April 1975] 16384/76 Heading B7H In a vehicle drive arrangement a pedal 2 is operated so that an air line 9 is connected via valve 3 and electromagnetic valve 5 to pressureoperated cylinders 12, 13 controlling the injection pump regulator 16 and engine-brake flap 14 in the exhaust passage. Valve 5 will only be opened to allow air to pass to cylinders 12, 13 when a bridging clutch of hydrodynamic coupling or converter 1 is engaged and consequently, the pressure operated switch 6 is closed. If engine speed falls to just above idling speed the bridging clutch will become released and switch 6 opened so that valve 5 will be shifted to the rest position in which cylinders 12, 13 are disconnected fron the air supply and vented by device 19 in valve 5. Regulator 16 is thus moved from the stop position I to the idling position II. Provision is made for the previous interruptedcircuit condition to be cancelled by closure of the switch 7 when the gear lever (not shown) is in the neutral position, thus shutting down the engine.

On the occurrence of a fault the shaft 7 and contacts 10 are rotated through 180 degrees out of engagement with fixed contacts 11, 11 and into engagement with contacts 11<1>, 11<1>. The contacts 11, 11<1> situated in the same horizontal plane are electrically connected, and the lower contacts of chamber 1 are in series with the upper contacts of chamber 2, the extreme contacts being connected to the lines. If during the short time taken for the contacts 10 to change over the cause of the @ault, for example, an arcing-ground, falling branch &c. has disappeared, the circuit is reestablished without synchronous machines having had time to fall out of step. If the fault persists, a second breaker may be arranged to clear it, or the same breaker may, after a timeinterval, operate in the same direction as before, or in the reverse direction. Preferably the drive is arranged so that the shaft is stopped in an intermediate position after a second opening has occurred. Longitudinal and radial oilblast openings 12<1>, 12 are provided in the chambers 1, 2, respectively, so as to ensure complete rupture of the circuit during the change over. The Specification refers also to shaft-rotations of less and more than 180 degrees and to the use of one chamber only. Two horizontal chambers may be separated by a common, verticallyarranged, driving mechanism and bevel gearing.

Abstract: 437,215. Regulating combustion in furnaces. INTERNATIONAL COMBUSTION, Ltd., Aldwych House, Aldwych, London, and MEAD, H., 103, Curzon Street, Long Eaton, Derbyshire. June 12, 1934, No. 17380. [Class 51 (i)] In apparatus for regulating the supply of fuel and air to furnaces in order to control the temperature of a medium heated by the furnace a control member which is moved to change the rate of supply of fuel is actuated through mechanism which is adjusted to change the limits of the path through which the member may be moved, so that the maximum and minimum rates of fuel supply are both raised or both lowered by each adjustment and the mechanism is arranged to be actuated so as to move the control member to one or other limit of its selected path in each adjusting movement. A slow speed motor E <1>, Fig. 2, is fitted with a crank E which oscillates a connecting rod D connected with a lever arm C carried by a sleeve C<1> fixed to a shaft A connected with the air supply damper. Concentric with, and abutting, the shaft A, is a second shaft (not shown) carrying a lever arm F adjustably coupled to the arm C by a pin-and-slot connection. The latter shaft is connected with a device for varying the rate of fuel supply. By altering the relative positions of the lever arms C and F by adjusting a wing nut K the upper and lower limits of movement of the arm F due to a given angular movement of the motor E<1> are either both raised or both lowered. The motor is actuated by a thermostat, pressure sensitive device or timing device and at each actuation moves the crank E through a given angle, say 180‹. By arranging the necessary electric contacts so that at each successive actuation the motor moves through angles of say 100‹ and 260‹ respectively, the effective angular movement of the arm F would be altered. In a modified form, Fig. 3, the motor drives two cranks, one being connected to the air supply damper by a rod D<2> and the other through a rod D<1> and an adjustable link L to the arm F. By varying the effective length of the link, the range of movement and the limits of movement of the arm F may be varied. Specification 405,655 is referred to.

[Classes 83 (ii) and 83 (iv).] Dividing by fusion.-Tubular stock or stock presenting surfaces in planes at an angle to one another, such as angle-bar stock, are formed by flame cutting into shaped articles, such as chain links including a link forming portion and a flange portion, by effecting relative movement of the flame and stock in the direction of the axis of the article and transverse thereto, and effecting partial rotation of the stock in reverse directions about an axis parallel to the length of the article in cutting those points at the intersection of two faces in different planes. An angle-bar 3 for forming chain links is secured between projections 21 and a screw clamp 2 in a cylinder 1 rotatable by a reversible electric motor 6 through spur and worm gear. The corner 4 of the bar is arranged in the axis of the cylinder and sufficient of the bar projects from the cylinder under the burner 5 so as to produce a chain link ; a releasable stop is secured to the bar behind the cylinder at a distance set by a portable distance-piece, so that the bar may be pushed forward after each operation until the stop engages the rear of the cylinder to feed sufficient of the bar forward to form the next link. When the burner has been traversed to cut the flange 3<1> from the point A to the point B, Fig. 4, the cylinder is rotated to cut the corner, and the burner then traversed to the point C, Fig. 5, whereupon the cylinder is rotated in the reverse direction to cut the corner at this point and the burner then traversed back to the point A as shown in Fig. 4. The burner carries a spring brush contact 18 which engages in turn stationary contacts 16, 17 in the circuit of a contactor 15 for reversing the motor at the required time. Spring-urged switches may alternatively be used closed by an actuator moving with the burner.
