Title: Improvements in or relating to refuse chutes
Inventor: PALMER HAROLD LAITHRAIN
IPC: E04F17/12
Filed: 1965-06-04
Abstract: 1,085,144. Hoppers for refuse shoots. TRUE FLUE Ltd. June 3, 1966 [June 4, 1965], No. 24054/65. Heading A4A. A hopper unit adapted to be applied to a refuse shoot to register with an aperture therein comprises a casing element 10 defining a passage, the lower wall of which is inclined downwardly from front to rear and the dimensions of which are such that at the rear end they match those of the aperture in the pipe; and a closure flap 15, mounted at the forward end of the passage, which is provided with rearwardly directed wing portions 17 and a secondary closure flap 18 disposed at an appropriate angle with respect thereto. An arcuate cowl or shield member 19 is also located within the passage defined by the casing element. The arrangement is such that when the closure flap 15 is outwardly opened the secondary flap 18 is automatically moved into the position dictated by abutment of the said flap with a sealing strip 20 on the shield member 19, thus effectively closing the passage and preventing egress of smells from the shoot whilst refuse is deposited in the container defined by the flap 15, the secondary flap 18 and their interconnecting wing portions 17. When the flap 15 is again moved to the closed position the refuse is discharged down the then appropriately inclined secondary flap 18 into the shoot, an extension portion 13 of the casing element serving to deflect the refuse outwardly from the wall of the pipe.

Title: An improved physico-chemical process for the extraction of celluloses from vegetablematerials in general, and a product obtained thereby
IPC: D21C3/22
Filed: 1952-09-25
Abstract: Cellulose is obtained from fibrous vegetable material by crushing the material and then treating it with a dilute solution of an oxidizing agent in the presence of caustic soda, sodium carbonate or the like so that non-cellulosic constituents of the material undergo hydrolysis and are removed.  The hydrolysis may be carried out at 30-50 DEG  C.  The oxidizing agent may be sodium, potassium or calcium hypochlorite; sodium or hydrogen peroxide; ammonium persulphate or sodium meta-perborate.  Mixtures of oxidizing agents may be used if desired.  Non-woody material such as straw, broom-corn, stems and cobs of maize, or genista is washed with water, ground and selected in lengths of 3-5 cm.  The material is washed and then passed through crushing machines to break knots and crush the fibres, and to expel moisture and air. Small quantities of oxidizing agents may be present during the crushing.  Woody material is washed and reduced to pieces of 2-5 cm. in length and then passed through crushing machines, preferably after being moistened with a dilute oxidizing solution. The crushed material may then be treated with a solution of sodium hypochlorite of specific gravity 1.15-1.18, together with caustic soda, sodium carbonate or the like to obtain an alkaline medium up to a pH of 9-12.  During the reaction, chlorine is liberated. This is collected and returned to the liquid, through which it is bubbled.  The heat liberated during the reaction may raise the temperature to 65 DEG  C.  The time of treatment may range from 1-6 hours.  The treatment time may be reduced by projecting light on to the material undergoing treatment.  At the end of the treatment the mass is filtered and the liquid is treated for the recovery of salts and chlorinated compounds formed during the reaction.  The liquid may then be re-used for treating a subsequent quantity of the crushed vegetable material.  The crude cellulose, freed from the bulk of treatment liquid, is washed with water at 40 DEG  C. in a tank provided with a stirrer to dissolve salts and chlorinated compounds, and it is further washed in Hollanders.  It is then subjected to an anti-chlor treatment with sodium thiosulphate solution, washed with water, treated with dilute sodium carbonate solution, washed again, filtered and dried.

Title: Improvements in or relating to permeability tuning arrangements for radio receivers or the like
IPC: H01F21/06
Filed: 1951-10-16
Abstract: 701,865. Adjusting radio apparatus. COLE, Ltd., E. K., CHAPMAN, C., and YATES, J. K. Oct. 16, 1952 [Oct. 16, 1951 May 23, 1952], Nos. 24125/51 and 13075/52. Class 40 (5) In a permeability-tuned radio receiver having a number of different wave-ranges, wherein tuning is carried out by a single control knob or handle, movement of which simultaneously effects movement of the cores of all the tuning coils, the cores of the coils for the short-wave range or ranges are arranged to move at a slower rate than the cores of the coils for the medium and/or long wave ranges. In the arrangement shown in Fig. 1 movement of the lever L effects movement of the cores of the coils, of which three are shown at C, D and E, the cores of the coils being attached to wires W which have threaded portions O screwed into threaded bushes pivotally mounted in an arm H attached to the lever L thus permitting initial adjustment of the core positions. Three short-wave coils are provided, one being shown at C, the other two being arranged behind it. Three medium-wave coils are also provided, the aerial tuning and R.F. amplifier tuning coils being at E and behind E, respectively, while the local oscillator coil is shown at D. The core of the medium-wave local oscillator coil thus moves at a rate different from that at which the cores of the corresponding R.F. tuning coils move so facilitating tracking. Pre-set tuning may be provided by arranging a number of adjustable stop members which have projections or recesses engaging with corresponding depressions or projections on the lever L. The depressions or projections on the lever L may be provided by a sleeve slidable on the lever so that the pre-set tuning may be utilized or not at will by sliding the sleeve into either an operative or inoperative position. In a second arangement of which Fig. 4 shows a side elevation and Fig. 6 a sectional plan view on the line 6-6 of Fig. 4, five pairs of coils are provided corresponding to three short-wave ranges, a long-wave range and a medium-wave range. The cores of the coils are attached by wires W to threaded members O which screw within threaded bushes on the arm H thus permitting initial adjustment of the core positions. Tuning is effected by rotation of the knob X which is attached to a rotatable rod U having a threaded portion passing within a threaded bush S. The bush S forms part of an extension Q attached to the arm H so that rotation of the knob X causes the arm H to move vertically. The coils of each corresponding pair may be arranged at slightly different distances along the arm H to enable accurate " tracking " to be obtained without the use of " padding " components.
