Title: An improved mixing valve
IPC: F16K5/12
Filed: 1960-10-12
Abstract: 914,537. Heating systems for buildings. BURKLE, W., and BURKLE, K., [trading as ZENTRA-APPABATEBAUA. BURKLE, O.H. G.]. Oct. 12, 1960 [Oct. 15, 1959; Feb. 20, 1960], No. 34973/60. Class 64 (2). [Also in Group XXIX] A manually-actuated mixing valve 15, Fig. 1, mixes hot flow fluid, e.g. from boiler 10 to heater 12 with cooler return fluid, e.g. from radiators 11, and comprises a rotary valve member having a control flange 35, Fig. 2, having a cut-away area of such a shape that the temperature of the mixture, e.g. flowing to the radiator, is substantially directly proportional to the angular disposition of the rotary valve. The hot flow and cooler return water may be proportioned between the two outlets 22, leading to the radiators 24 returning to the boiler, by four flanges, although only one is shown controlling the hot flow to outlet 22. The shape of the cut-away portion is determined by a formula based on various characteristics of the hot water flow-heating system and gives a theoretical shape of the cut-away for exact linearity between mixture temperature and angular rotation of the valve as indicated by the dotted curve i, Fig. 9. In order to obtain a smaller valve member, the curve W is used to give an approximately linear relationship. According to the description the cut-away may be concave, convex, triangular or a parallel-sided slot.

[Class 26.] In a siphondischarge waterwaste-preventer of the kind comprising a partially rotatable horizontal operating spindle 5 carrying an arm 3 connected to the plunger rod 2 by a link 1 which is pivotally attached to the arm and rod, the arm is slidably mounted within a carrier 4 itself slidably mounted upon the spindle 5, means, such as screws 7, being provided for securing the parts in the desired positions. The underside of the arm 3, or the link 1, may be provided with a projection 11 which serves to prevent angular movement of the link with respect to the arm after a predetermined turning movement of the spindle 5, thereby preventing undue displacement of the plunger spindle 2. The link 1 is bifurcated at its ends 1a, 1b and the spindle 5 may have a flat portion to facilitate engagement with the corresponding screw 7.

Abstract: 627,608. Impedance networks. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., and MORTLEY, W. S. Dec. 5, 1946, No. 36066. [Class 40 (viii)] A piezo - electrically controlled circuit includee a number of crystal circuits designed to have a common resonant frequency and loss intro. ducing coupling means connect points in the cir. cuits which have sub. stantially no potential difference therebetween in operation at the common frequency but are not at the same potential at other frequencies. The loss producing means will then damp out oscillations at all frequencies other than the common frequency. In order to ensure that the unwanted resonances in the crystals are dissimilar, a slight deliberate difference may be made in their electrode or quartz dimensions. As shown, crystals C are coupled to a negative inductance D by lines of length #/4, where A is the common resonant wave length and damping- resistances R are inserted. At unwanted resonance frequencies in one crystal and its attendant network, the other crystal will act substantially as a short circuit and its resistance R will damp the oscillations. Specification 618,967 is referred to.

Title: Improvements in and relating to a liquid boiler for evaporation and distillation plants
IPC: B01D1/06
Filed: 1956-11-28
Abstract: <PICT:0802715/III/1> In a liquid boiler for evaporation and distillation plants the liquid flows continuously through two nests of tubes arranged within a casing having an inlet and outlet for a continuously flowing heating medium.  The tubes are all of substantially the same length and parallel to one another.  The upstream nest of two or more tubes are connected in series and the downstream nest in parallel, the arrangement being such that the liquid commences to boil at or about the region of communication between the two nests of tubes.  A cylindrical boiler 1 has partitions 3 and 4 at the top and bottom, between which the tubes extend.  Heating medium is introduced through inlet 8 and is guided over the external surfaces of the tubes by partition 6, vertical guide tube 7 and baffleplates 10 to the outlet 9.  The liquid to be boiled enters through inlet 16 and flows through tubes a1, a2, a3, a4 arranged in series and connected by short horizontal tubes 11 above partition 3, the last of these tubes terminating in distribution chamber 12, in or at which the liquid starts to boil and increase in volume.  The boiling liquid then passes into a second nest of parallel tubes, b, each consisting of a riser part, b1, from chamber 12, which is joined by a short horizontal tube 13 to a downcomer part b2, which terminates in collection chamber 14.  The liquid passes from chamber 14 through outlet 15 to a vapour separator (not shown) from which the liquid may be recycled to 16. The distribution of the tubes may be varied and the partition 6 and the guide tube 7 may be dispensed with.  The short horizontal tubes 11 and 13 may be replaced by channels in a tight fitting lid.  The apparatus may be used for the evaporation of milk or the distillation of sea water.

When a paper backing layer is employed the integrated mica sheet may be applied thereto while the paper layer is wet during the course of its manufacture. The bonding of the integrated mica sheet and the backing layer may be effected by a binder or, in the case of paper or textile backings, by intertwining of the fibres of the backing into the integrated mica sheet. The binder may be applied only around the peripheral boundary. Impregnation with the solventless binder e.g. an epoxy resin may be carried out before and/or after bonding of the layers suitably under reduced pressure.
