Title: Improvements in and relating to hydraulic drives
IPC: F15B11/048
Filed: 1962-07-03
Abstract: 964,189. Machine tool details. F. WEGERDT. July 3, 1962 [July 29, 1961], No. 25418/62. Heading B3B. [Also in Division F1] In a machine tool, an hydraulic linear or rotary motor AP performs intermittent back- and-forth movements with reversal at a constant point at least in one direction of movement. As illustrated in Fig. 3, the point at which the motor starts to decelerate always lies on the sloping line, there being a time delay mechanism which, when a signal to reverse is given at point S1, prevents deceleration until the point Via is reached when the speed is V2, but is inoperative when the speed is V1. In the embodiment of Fig. 4, a reversible variable-output pump has its output in each direction adjusted by stops A1, A2 which limit the movements of an operating piston K3. The output of the pump is supplied to a piston K1 moving a table T carrying reversing stops T1, T2. The stops may act mechanically (as shown), or electrically or hydraulically to reverse a valve K2 supplied with pressure by a pump ZP and driving to operate the piston K3 through timing valves Z1, Z2. The timing valves are constituted by pistons moved against springs Fd1, Fd2 by fluid supplied by a variable delivery-pump SP controlled simultaneously with the pump AP. The length of the time delay is set by stops Sp1, Sp2 adjusted simultaneously with the stops A1, A2. A piston valve S causes the supply from the pump SP to be delivered always to a line 3. When the pump AP is delivering at maximum output the time delay is zero. In a modification, a vertically reciprocating working piston has an exact reversal point in the feed direction only. The acceleration of the return stroke is controlled by a throttle valve in the exhaust line from the reversing valve and the pump SP is omitted. In a further modification, the working piston K10, Fig. 6, contains a relief valve RV1. Fluid enters at a port 1 for the working stroke. On the return stroke, fluid cannot escape from the port 1 due to a non-return valve in the circuit. The fluid in the space F1 therefore passes to the space F2 through the valve RV1.

Patent GB-647062-A (GB)
Title: Improvements in or relating to the manufacture of heat and sound insulating materials
IPC: C08L89/00
Filed: 1947-09-23
Abstract: Insulating plates are formed by a method wherein a water-soluble binding agent, which sets on heating, e.g. 2-4 per cent of blood albumin with or without a similar quantity of lime, is added to peat moss and the moss and binding agent are then heated under pressure so that the binding agent hardens and the peat moss is pressed into a porous felt-like structure.  Pressure may be applied to the peat moss or mixture to expel surplus moisture before the heat-hardening process is applied and, if applied to the mixture, the pressure may be decreased during the hardening.  Pressing is accompanied by suction to remove steam and water.  To impart greater firmness and density to layers of the plate, e.g. one or both surface layers, it is arranged that these layers have a greater concentration of binding agent.

Title: Process for preparing synthetic crystalline zeolites
Filed: 1960-07-25
Abstract: A synthetic crystalline zeolite, the same as that designated zeolite X in Specification 777,233, is prepared by ageing a calcined kaolinitic clay in an aqueous solution of sodium hydroxide and hydrous silica and thereafter heating the solution at 50 DEG C. to the boiling point to produce the zeolite, the weight ratio of the reactant, at least during the heating step being 9-20 parts H2O, 0,2-0,4 parts SiO2 and 0,9-2 parts Na2O per part of calcined clay. Calcination may be effected at 500 DEG -800 DEG C. for 1-18 hours and the ageing may be effected at 20 DEG -40 DEG C.  The term "hydrous silica" includes in this context sodium silicate, and this is the preferred reactant.  According to Example (1) kaolin calcined at 700 DEG C. for 2 hours was aged as a slurry in of sodium hydroxide and silicate at 25 DEG C. for 72 hours after which it was refluxed at 100 DEG C. for 10 hours and the zeolite recovered by filtering and washing.  Further Examples 2, 4, 5 and 6 exemplify the effect of calcination timer and temperatures, whilst Example 7 exemplifies the use of calcined halloysite. Example 3 is comparative, the aging step being omitted and the product being sodalite.  Ion exchanged forms of the zeolite X may be obtained by conventional means.

Filed: 1922-09-26
Abstract: 213,293. Marks, E. C. R., (Cleveland Metal Products Co.). Sept. 26, 1922. Wick burners, annular; flame-spreaders. - Wick burners, having a flamespreader which is moved by the wick during its initial upward movement, and then renders operative automatic wick stop mechanism, such as described in Specification 206.545, are provided with locking or latching means whereby vertical movement of the spreader relatively to a span member operatively associated with the stop mechanism is prevented, the latching means being rendered ineffective when the spreader is to be removed. In the form of spreader shown in Fig. 1, pendants 12, pivoted to a support 10 which is secured to a span member 4, normally repose, when hanging freely, in an annular recess 15 in the spreader and are retained against swinging inwardly by the tapered end of a pin 17. To remove the spreader the pin is withdrawn from between the pendants which are swung inwardly by contact with the lower end of the spreader sleeve as :.t is lifted by means of the pin. Modified latching means include rollers and pivoted latch plates in place of the pendants and balls, which are normally held against the frusto conical upper end of a post secured to the span member but which are separated to unlatch the spreader by means of a forked actuator by which the spreader is grasped. A further modification shown in Figs. 6 and 8 comprises a post 40 within the bifurcated upper end of which is pivoted a latch plate 45 having a keeper portion 46 normally projected over the top wall 42 of the spreader by means of a weighted end 47. To remove the spreader a collar 51 loosely connected to the spreader by a member 52 is grasped and its initial upward movement engages a nose 50 of the latch plate causing it to swing inwardly and retract the keeper portion to permit withdrawal of the spreader. In other modifications the latching means consist of locking levers or plates pivoted to the spreader and normally engaging the conical head of a post secured to the span member.

Title: Improvements in and relating to electric current rectifiers operating with rotating conductive liquid jets
IPC: H02M1/30
Filed: 1936-09-25
Abstract: 463,857. Mercury jet switches. SIEMENS - SCHUCKERTWERKE AKT.- GES. Sept. 25, 1936, No. 26075. Convention date, Oct. 28, 1935. [Class 38 (v)] [Also in Group XXXV] A rotary liquidjet rectifier comprises two sets of fixed contacts 8, 9 one of which is con. nected to the neutral point of the supply transformer 6 through the load circuit and the other to the free phase ends of the winding, the pairs of opposed contacts being bridged in turn by the liquid jet. To avoid momentary short-circuits by drops of liquid falling from one contact to the other, the contacts may be arranged to co-operate with a downwardly directed jet. Alternatively, the jet carrier may be arranged so that an insulating barrier, e.g. a disc 17, Fig. 8, is interposed between the contacts at the times when they are not bridged by the jet. Other methods of avoiding this defect are to arrange the fixed contacts widely separated and reduce the voltage drop by including a solid conducting member in the jet-stream or by using conductive nozzles 5, 12 of the form shown in Fig. 4. Still another method is to use a rotary member comprising nozzles delivering air or nitrogen interposed between nozzles delivering conducting liquid so that drops of liquid remaining on the contacts are blown away. In one arrangement the gas is forced along grooves formed in an insulating disc carrying metallic nozzles for the conducting liquid. In another form, Fig. 13, the rotary member is in the form of a tube 25, divided into two chambers by a partition 33. Conducting liquid is supplied to the chamber 34 and issues between the two sets of fixed contacts 26, 27. Gas is supplied to the other chamber 35 and issues between the contacts at the times when the conducting liquid is cut off. In an alternative arrangement of this kind, Fig. 15 (not shown), the rotary member has a central passage for the conducting liquid with compartments on each side thereof for gas. Fig. 17 shows another arrangement in which the rotary member is in the form of a distributing disc 61 extending betweenrings of fixed contacts 55, 56 the disc having radial ribs 62 at the parts where the conducting liquid issues to prevent disintegration of the jet. Between the sets of liquid nozzles so formed, the disc is grooved for the passage of flushing gas. In order that the diameter of the apparatus may be kept small for a given output a number of nozzle groups with their associated rings of contacts may be arranged above each other, Fig. 20 (not shown).
