Abstract: 430,428. Pasteurizing liquids. STAVNSBJERG, J. R. H., 4, Storchsvej, Copenhagen. Dec. 19, 1933, No. 35680. [Class 49] In apparatus for pasteurizing milk, beer, &c., in bottles or other containers consisting of a series of compartments 1-7 filled with water or other liquid heating medium which circulates therethrough, and into which are placed baskets or like receptacles h in which the bottles are inserted, the compartments being successively and periodically heated up to and held at pasteurizing temperature, the openings between the compartments 1-7 are controlled by valves a each of which is constructed for co-operation with the baskets so that it closes, e.g. by its own weight or under spring influence, when there is no basket in the compartment next after the valve in the direction of the liquid circulation and it is opened and kept open by the basket when the latter is placed in this compartment. The valve may consist of a pivotally mounted flap a with levers b which are engaged by the bottom of the basket h, the valve closing by its own weight when the basket is removed. When the compartments 1-7 each contain a basket h the valves will all be open and the water circulates freely through the apparatus. To obtain even circulation, one side of each basket h consists of a plate i which forms with the compartment wall s a chamber up which the water must pass and over the top edge of plate i which may be formed as a separate portion x vertically adjustable to vary the height. Wedges g are provided to force the basket h and plate i against angle irons r. The water may be circulated on immersion of the baskets only or by a pump p connected between the first and last compartments, which are also connected by another pipe. Overflow is discharged from compartment 7 through a container k and pipe kl. Excess water is discharged from each compartment by a valve c which is connected to a flat spring e which extends into the next compartment where it is engaged by the basket h therein to keep the valve c closed, the valve opening when the basket is removed. The extent to which the valve opens is regulated by a screw f.

Title: Cellulosic filter for tobacco smoke
IPC: A24D3/14
Filed: 1965-08-20
Abstract: A tobacco smoke filter comprises a cellulosic carrier element having incorporated therein a normally liquid polyethoxylated monohydric derivative of a hydrocarbon containing 10-20 carbon atoms, the derivative consisting of an alkylphenol or a saturated alcohol. Preferably from 5-25% by weight of the polyethoxylated derivative is contained in the carrier which may be an absorbent paper sheet consolidated in rod form.  The derivative is incorporated in the carrier by dispersing it in a web moistening liquid which is applied to the carrier web by spraying, immersion or roll-coating.  The web is then dried and formed into a rod.  Quantitative examples are given for filters containing 10-15% by weight of (a) nonylphenol combined with an average of 9-10 moles of ethylene oxide per mole of the phenol and (b) tridecyl alcohol combined with an average of 15 moles of ethylene oxide per mole of alcohol.

The detector 9 is supported on the already levelled track immediately behind the chassis. The source 8 may, however, be either at the front end of the chassis 1 or mounted on a separate trolley 13 having independent driving gear 12 for moving it along the track, the driving gear being controlled by a radio control system comprising a transmitter 14 and a receiver 15 on the trolley 13, such that the trolley is maintained a fixed distance in advance of the transmitter position. In the modification of Fig. 2, the reference beam from the infra-red source 8 is divergent and a pair of detectors 9, one over each rail, is used, there being additional shutters 17<SP>1</SP>, 17<SP>11</SP>, one for each rail so that tamping may be carried out to the correct degree for each rail under control of the respective detectors. A system of wires 37 co-operating with a detector 38 may also be used for automatically applying lateral forces to the rails to correct misalignment. Trolley 13 is maintained in fixed relationship to the chassis 1 by a link 13<SP>1</SP>.

Title: Electrolytic regeneration of alkali liquors
Inventor: RYDER CHARLES
IPC: C25B15/08
Filed: 1964-09-02
Abstract: <PICT:1084196/C6-C7/1> A process for removing undesired components, for example alkali metal thiosulphates, thiocyanates and/or ferrocyanides from an alkaline liquor containing an organic additive such as glycine comprises electrolyzing the liquor in an electrolytic cell 10 which is divided into three chambers, namely an anolyte chamber 15, a central chamber 16 and a catholyte chamber 17 by means of an anion exchange membrane 18 and either a cation exchange membrane or simple porous membrane 19, the pH of anolyte being maintained below 7, e.g. 2.5-7, and the pH of the catholyte being maintained above 7, preferably above 12.  Initially the catholyte chamber is filled with potassium hydroxide solution and the anolyte chamber with potassium sulphate.  A source of free iron, e.g. in the form of scrap iron, may be provided in the anolyte chamber.  Small quantities of the liquor to be treated may be passed into the anolyte and catholyte chambers during electrolysis and pH control in the anolyte and catholyte chambers may be effected by controlling the relative flow rates of liquor into the three chambers.  The cell is provided with double walls 11, 12, the gap there-between being filled with water into which the sides of the lid 13 dip to provide a gas-tight seal.  A gas inlet 51 and outlet 52 are provided so that an inert gas such as nitrogen may be passed over the liquor in the cell to remove gaseous products of the electrolysis.  The anolyte may be constantly circulated through pipe 35, filter 45, pump 46 and pipe 47 and then returned to the cell, precipitated sulphur and Prussian blue in the anolyte being maintained in suspension thereby, and are removed by the filter 45.  Electrolyte is supplied to the three chambers of the cell via pipe 25 and pipes 26, 27, 28 respectively, and may be removed therefrom via the pipes 32, 35, 36 respectively and via the outlet pipe 33.  Valves are positioned as required throughout the external circuitry.  The anode and cathode may be formed of carbon or stainless steel.  The process may be used to remove undesired components from used Alkazid lye, which primarily consists of an aqueous solution of potassium dimethyl glycine.

Abstract: 1280032 Signal delaying amplifiers PRESEARCH Inc 17 July 1969 [31 July 1968] 36123/69 Heading H3T  A device for delaying a wide band-width input signal comprises a phase inverter TR1, a resistance element R and a reactance element C connected in series across said phase inverter TR1, said elements being arranged to produce a limited shift that is substantially proportional to the frequency of the input signal and means for varying the magnitude of one of the elements in response to a control signal so as to vary the delay of the input signal. The specification shows that if the phase shift is limited to approximately 12 degrees, the phase shift is proportional to frequency and the delayed signal is a substantial replica of the input signal. Resistance R may be a cadmium sulphide photocell. Alternatively, the delay may be varied by means of a voltage-dependent, heat-dependent or pressure-dependent resistor or capacitor. The transistors may be replaced by vacuum tubes, field effect transistors or transformers.

[Class 7 (iii).] Pumps b, l supply driving and igniting fuels to an injection valve t, and the pumps are actuated so that the injection valve remains open after the driving fuel has been delivered to the engine cylinder and until a charge of igniting fuel has been delivered by the pump l which forces the remainder of the driving fuel into the cylinder and leaves the igniting fuel in the valve to be injected into the cylinder in advance of the next charge of driving fuel. A lever d is pivoted to the plunger c of the driving fuel pump and is adjusted either manually or automatically by an eccentric f according to the load on the engine. The lever d carries tappets g, i which open in succession a relief valve h in the driving fuel pump and actuate the plunger k of the ignition fuel pump. In a modified construction, the pumps b, l are actuated independently and when the lever d opens a relief valve in the pump b to terminate the delivery of the driving fuel, it closes a relief valve in the pump l to cause the igniting fuel pump to deliver fuel.
