Title: Improvements in continuous defecation of sugar juices in which the alkalinity is neutralised to a predetermined extent by treatment with an acid such as carbon dioxide gas
IPC: C13B20/00
Filed: 1927-05-09
Abstract: 270,757. Dorr Co., (Assignees of Ramsey, E. R., and Bull, A. W.). May 8, 1926, [Convention date]. Mechanical interrupters.-In the purification of sugar juices employing for example milk of lime and carbon dioxide gas, the alkalinity of the treated juice is determined in relation to the electrical resistance of a portion of the juice in which dissolution and reaction are completed. The rate of feed of a treating agent in the purification process is controlled automatically in accordance with the variations in electrical resistance produced, and the regulation is effected intermittently in order that the juice condition may become stabilized after each treatment.The resistance measuring device, Fig. 3, comprises a vessel 48 containing two pairs of electrodes 56, 56<1> connected respectively to a controlling galvanometer x and a recording galvanometer y, Fig. 4, through Wheatstone bridge circuits 100, 100' fed by transformers 96, 96<1> from the mains 102, 103. The construction of the recording and controlling galvanometers is similar, the record being made either by scale or graph. The controller portion of galvanometer x comprises a frame 159 rocked by a cam 162 on a motor shaft 106 which also carries contact cams 157, 157<1> connected by brushes 179, 180 with lines 118, 122. Lever arms 168, 169 pivoted to fixed frame 158 are provided with extensions 170, 171 between which the galvanometer needle is reciprocated by the rocking-frame 159. A rocking-bar 172 is provided with pins 177, 178 engaged by the lever arms 168, 169 and also carries brushes 173, 174 connected in line 117. As the alkalinity of the juice varies, the galvanometer needle is caught and held for a longer or shorter period between the extension 170 or 171 and the rocking-frame 159. The lever arm 168 or 169 tilts and rocks the bar 172 engaging either brush 173 or 174 with the contact disc 157, or 157<1>. Depending upon which contacts have been made, current is supplied through solenoids 121. 125 to operate switches 126 - - 129 for closing the armature and field circuit 139 of a reversible motor 138 operating the carbon dioxide valve 40. In order to provide that the juice condition is stabilized after each treatment, the line circuit 117 to the controller is periodically interrupted by insulation cams 107, 108 driven by a motor 110 and provided with contact segments 111, 112.

Title: Improvements relating to film packaging
Inventor: WATTS RIDLEY
IPC: B65B11/52
Filed: 1969-03-10
Abstract: 1,240,043. Packaging. AMERICAN PACKAGING CORP. 10 March, 1969, No. 12525/69. Heading B8C. A skin packaging machine has a film frame 24 which moves between a stationary heater 20, and a stationary vacuum platen 16, the heater and frame being supported in cantilever fashion by two upright supports 18 and 19. The frame 24 comprises upper and lower parts which clamp the film F between them by the action of a latch 90. The frame is pivotally mounted on brackets (70), Figs. 3 and 7 (not shown), which extend through slots 32 in the supports and slidably embrace posts (22) within the pillars. The brackets are raised and lowered by chain drives within the supports, the direction of drive being reversed by limit switches. The pivoted mounting of the frame is such as to allow the frame to pivot upwardly if it meets an obstruction during its downward travel. The heater 20 is vertically adjustable and may be pivoted upwardly to facilitate access to its heating elements. The elements are of ribbon type so that they have low thermal inertia. The heater is energized while the frame 24 is in its uppermost position, and during energization a blower draws air from the space above the film through apertures 62 and returns it over the heating elements to the space. When the frame is lowered, the heater is de-energized but the blower remains in operation for a predetermined period to cool the elements to ambient temperature. In an alternative mode of operation, the heater may remain energized while vacuum is applied to the film in the lowered frame. In another mode, the blower may be used only to cool the elements after their de-energization. In operation, the frame is loaded manually and raised by operation of a manual switch. The articles to be packaged are placed manually on the platen after which the operating cycle proceeds automatically to the point where the packaged articles are to be removed. The duration and degree of evacuation and of heating may be preset on a control panel 14.

Title: Improvements in or relating to die-casting machines
IPC: B22D17/06
Filed: 1929-04-26
Abstract: 335,569. Bradwell, H., Musson, H., and Nevins, J. R., (Representatives of Nevins, L, R. A.), and Ball, A. C. April 26, 1929. Casting-machines ; metal-pouring.-A die-casting machine has a forcing-chamber 4 and a melting pot 5 which are heated independently. The chamber 4 is heated, to a lower temperature than the pot 5, by burners 18, 19 and is carried by parallel arms 61 so that its nozzles 10, 13 can be engaged alternately with openings of the pot and die. When in contact with the pot a supply of aluminium or other metal is forced in by air pressure. A hand lever 22 is then lifted thereby moving the chamber 4, through linkwork 28, 29, 30, into contact with the die and a stopper 20, through an eccentric 23 and linkwork 24, 25, 26, into contact with the nozzle 10. The handle 17 of two-way valve 16, Fig. 3, normally held by an abutment 38, can, in the new position of the chamber 4 &c., be moved in the direction of the arrow to connect the chamber to a high pressure supply 15, thus charging the die. When the handle 17 is released it is returned by a spring 36 to close the pressure supply and open the chamber 4 to exhaust. The die support 2 is vertically adjustable by a screw 41. In a modification the chamber 4 is stationary and is charged by a ladle through the top 56 which is then closed by a toggle-operated adjustable stopper 53 carried by a pivoted yoke 55<a> so that it can be swung aside. The die 39 is carried on a slide 45 operated by a lever 48 to bring the die into contact with the nozzle 13.

Title: Improved priority determing circuit
IPC: H04N7/173
Filed: 1959-12-16
Abstract: 935,376. Electric selective signalling systems. SKIATRON ELECTRONICS & TELEVISION CORPORATION. Dec. 16, 1959 [Dec. 17, 1958], No. 12961/60. Divided out of 935,371. Class 40 (1). A priority determining circuit is described for use in the subscription television system described in Specification 935,371, which is referred to. The circuit has three input leads I, II and III and three output leads P1, P11 and P111 and on receipt of a succession of input signals it produces a similar succession of output signals on the correspondingly numbered leads. Only one output signal can occur at any time and each is of the same duration. If two or more input signals arrive simultaneously (or in rapid succession) the output signal on lead P1 takes priority over that on lead P 11' which in turn takes priority over that on lead P111. This is achieved by an arrangement of three and gates 458, 460 and 462. The input signals are registered on flip-flops, gate II only being able to open when flip-flop I is off and gate III only being able to open when both flip-flops I and II are off. The operation is as follows: If the input signals arrive together, say on leads II and III, flip-flops II and III are set on and a one signal passes through a gate 448, a differentiator and a clipper and the result is that a one emerges from gate 460 passes via a gate 466 and triggers a monostable multi-vibrator to produce an output signal of 22 m. secs. duration of lead P11. The one also passes via an or gate 470 to trigger a monostable multivibrator 486 which inhibits gate 448 for 140 m. secs. Thus after the emergence of the one from gate 460 and the signal on lead P11 nothing further. happens for 140 m. secs. during which period flip-flop II is reset. At the end of this period of 140 m. secs. the one registered in flip-flop III causes an output signal to be produced, in a similar way, on lead P111.
