Title: Improvements in or relating to hot-gas reciprocating engines
IPC: F02G1/055
Filed: 1946-12-03
Abstract: 632,669. Heatexchangers; refrigerating engines. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN. Dec. 3, 1946, No. 35761. Convention date, Dec. 6, 1945. [Classes 29 and 64(iii)] [Also in Group XXVII] The working space of a hot gas engine or refrigerating engine is surrounded by an annular space subdivided into a plurality of spaces for the working medium and a plurality of spaces for a medium required to exchange heat with the working medium, in such a manner that a sectional view normal to the longitudinal axis of the annular space shows both spaces for the working medium and spaces for the medium required to exchange heat with the working medium the subdivision being effected by partitions which are provided with ribs on one or both sides, which ribs form sets of parallel ducts for the working medium and/or for the medium required to exchange heat with the working medium the ducts being at an angle with the longitudinal direction of the associated partition. In one e arrangement comprising a hot gas engine tubes with ribs on their exterior inclined to the axis of the tubes, project into the heater which is formed by an annular space around the cylinder. The insides of the tubes are divided into two by baffles which extend nearly to closed inner ends. The gases from a burner which heats the head of the cylinder pass through the tubes along one side of the baffle and return along the other side. In another arrangement Figs. 2, 3 and 4 the working medium from a cylinder 21 flows (arrows QQ) through spaces 42, bounded in part by a strip 24 bent as shown in Fig. 3, to a regenerator 27. The strip 24 is located in an annular space between the cylinder and an outer cylindrical wall 33. The flue gases from a burner (not shown), flow (arrows PP) through spaces 43 at the other side of the strip 24. Screens 31 are provided to prevent the strip from distorting under the pressure of the working medium and to force the flue gases to flow through channels formed by portions 26 pressed in the strip 24. Alternatively grooves may be formed by milling. A third arrangement is shown in Fig. 6 which is a crosssection through a portion of a cylinder at the position of a heater. Ribs 58 are formed on partitions 57. The working medium flows through channels 53 which extend longitudinally and longitudinally extending burners 55 located in channels 54 heat the ribs 58 on the side of the partitions nearest them.

Abstract: 1515716 Moulding replicas of statues &c. H V DURSY 29 Aug 1975 35783/75 Heading B5A Replicas of statues, statuettes, figurines and like free-standing works of art are made by: surrounding the original with boards 7 (Fig. 3) arranged in a plane containing the largest dimensions of the original, drilling holes through these boards and inserting sleeves (e.g. metal sleeves) 3 therein; surrounding the projecting sleeve ends by rubber rings; applying a partly prevulcanized rubber 4 to the side of the boards on which the sleeves project and the corresponding side of the original, and vulcanizing the rubber; applying over this rubber coating a curable plastics compound 6 which is then cured; removing the boards while leaving the sleeves in position, so that the parts of the sleeves which were previously embedded in the boards project rearwardly of the rubber skin; applying a release agent to the rear face of the rubber skin and forming thereon a rubber skin/cured resin rear mould half 6b (Fig. 5) in an analogous manner to the front mould half 6a; separating the two mould halves and removing the original; reassembling the mould halves and locking them by inserting bolts through the sleeves and threading nuts onto the bolts; and casting the replica in the mould sections. The replica may be formed with a core of epoxy resin containing quartz gravel covered with a lightly filled epoxy resin, and at least the outer layer may be spread on the mould halves before assembly of the mould. The mould may be made in three or more sections by further subdivision by means of boards at right angles to the original boards. The reproduction of areas of complicated surface geometry may be improved by applying to those areas after application of the rubber but before application of the curable plastics compound a foamable resin and allowing it to foam.

Patent GB-1460310-A (GB)
Title: Earth fault detector
IPC: H01H83/04
Filed: 1974-08-14
Abstract: 1460310 Protective devices MERLIN GERIN 14 Aug 1974 [20 Aug 1973] 35874/74 Heading H2K An earth fault detector in a housing secured to the moulded insulating material housing of an automatic circuit breaker comprises a testing means having a series connected resistor and switch for causing an artificial earth fault by closing the switch, wherein the switch is automatically opened again through mechanical linkage by tripping means of the automatic circuit breaker when the tripping means moves into the tripped position. Two push buttons are employed to operate the switch, one being the reset button 30 of the tripping means and the other a test button 28. Under normal conditions the reset button 30 is depressed and deflects a contact blade 54 of the switch towards the right, so that when the test button is depressed to move associated contact blade 56 to the left the two contact blades contact and the switch 26 is closed. This causes an out of balance current in transformer 14 and the tripping mechanism trips by rotating latch member 40 to release a trip lever 36 which in turn rotates a link 50 which pushes up the reset button 30 automatically causing contact blade 54 to be released to deflect away from contact blade 56 and open the switch 26 again. A fuse may be incorporated in series with the resistor 24 and switch 26, Fig. 4, not shown.

Title: Blade folding mechanism for rotary wing aircraft
IPC: B64C27/50
Filed: 1964-09-02
Abstract: 1,036,028. Folding helicopter rotor blades. BOEING CO. Sept. 2, 1964 [Sept. 18, 1963], No. 36029/64. Heading B7W. A rotor blade of a rotary wing aircraft has a lead-lag hinge 15 on a pitch bearing housing 14 rotatable about a pitch axis, and an actuator 21, comprising an electric motor and combined reduction gears, having arms 20<SP>1</SP>, 22 between which relative movement is produced by the actuator to fold the blade about the hinge 15. The arm 20<SP>1</SP> is connected through a damper 18, which serves to damp the pivoting movement of the blade during rotation, to the blade socket 16, and the arm 22 is connected by rods 23, 27 to a pin 28 and a cam 33 mounted on a shaft 25. The cam is engaged by a follower 36 mounted on a housing 38 (Fig. 3, not shown) rotatable about a shaft 39, and a tooth 45 on the arm 20<SP>1</SP> engages a recess in a projection of the housing 38, thus holding the arm 20<SP>1</SP> fixed relative to the housing 14 when the blade is unfolded. To fold the blade the actuator is operated to tend to rotate the arm 20<SP>1</SP> anticlockwise and the arm 22 clockwise. First the arm 22 rotates, pressing the pin 28 into a bush 30 to lock the blade against pitch changes, this movement being stopped by a flange 32 on the pin. The cam 33 is so arranged that at this point the follower has just reached the bend in the cam track and the torque on the arm 20<SP>1</SP> separates the tooth 45 and its groove, and, acting through the damper 18, pivots the blade socket 16 and blade 11 anticlockwise. The blade is stopped by the stop 57 in one of two positions according to the position of an actuating mechanism 69 which strikes the stop. A flange 54 on the blade socket 16 engages an arm 50 on the housing 38 so that the latter is held in such a position that on unfolding the blade the tooth 45 will engage the groove.

Title: Loud Speaker Enclosure
Inventor: MURRAY EDWARD JAMES
IPC: H04R1/28
Filed: 1967-08-04
Abstract: 1,192,826. Loudspeaker enclosures. E. J. MURRY. 4 Aug., 1967 [8 Aug., 1966], No. 36030/67. Heading H4J. A loudspeaker enclosure has a front plate 11, generally triangular and having concave sides 14, and a triangular back plate 12. An apertured dispersion cone-horn 15 extends between the plates 11, 12 for passage of higher frequency sounds. Three solid webs 22 extend from the external wall of the cone-horn 15 between the space between the front and back plates 11, 12 to divide the space into three equal parts. A back opening 19 receives a diaphragm speaker 18, preferably a "woofer" in front of which is a "tweeter" 20. Three tubes 23 provide vents controlling the escape of air from the rear of the enclosure. The cone-horn 15 is preferably hollow and exponential but may instead have a plurality of holes (25), Fig. 5 (not shown). In use, the enclosure is in the upper comer of a room, e.g. sealed against the side walls and ceiling by adhesive tape. "Tweeter" sounds pass through the cone-horn 15 into the room. Lower frequency sounds first hit the outer wall of the cone-horn 15 and are reflected by the webs 22 to the ceiling and room side walls. They exit from the enclosure through the spaces formed by the concave walls 14 of the front plate 11 and the room walls and ceiling. The venting of the tubes 23 and thereby the sound quality is selectively controlled by concentric plugs 24 in such tubes.

Abstract: 1349027 Recording-apparatus HONEYWELL Inc 4 Aug 1971 [12 Aug 1970] 36729/71 Heading G1J A multi-point recorder in which a plurality of channels are sequentially scanned to sense the values of the input signals thereon and the values are then recorded on a record medium 31 includes a solid state electronic digital programmer 40 which in operation programs the scanning (SSA, 68, 379, 4, 5) of the input channels (1, 2, 3) and the recording of the signals sensed (DPR, 65). A solenoid 68 rotates scanning contacts 4, 5 and a solenoid 65 actuates a dot printer in response to pulse signals SSA and DPA produced by pulse generating circuits, Figs.10 to 17 (not shown), in response to timing signals T1, T2 derived from clock pulses and the traces of dots corresponding to say 24 channels are identified by marks printed from a number wheel actuated to print by a solenoid 66 in response to pulse signals NPR produced in synchronisation with the scanning mechanism. A switch 384 Figs.2, 9 allows selection of the frequency of these pulses NPR at submultiples of the scanning frequency of 1/25, 1/49 and 1/97 through the circuit of Fig.19 (not shown) and the length of a recording cycle may be selected by setting print-interval switches 301 to 303 through the circuit of Fig.20 (not shown). The scanning advanced pulse signals SSA and number wheel advance pulse signals NWA to solenoids 68 and 67 respectively are synchronised by synchronising circuit in response to pulse signals SYN, NWFB fed back to the programmer 40 from switches actuated by the scanning mechanism and numeral wheel respectively.  The dot printer and numeral wheel are mounted on a carriage 30 driven transversely  of the record strip 31 by a servo motor 17 in a measuring circuit, the position of the carriage is detected by a detector and after a predetermined interval from the beginning of each individual channel measuring cycle, the programmer 40 produces a signal causing the detector to determine whether the position of  the carriage is satisfactory and to initiate an alarm signal if necessary Figs.18, 21 (not shown). The time interval is determined by the setting of switches 304, 305, Fig.9. The mechanism of Figs.3 to 8 is substantially the same as that described in Specification 1229757. A selector 383 enables alternative modes of operation to be programmed. If it is desired to record selected channels only these are selected from an array 382 of channel switches, the selector 383 is set to SOP position and the programmer operates through CHIP B, Fig.9, described with reference to Figs.22 to 28 (not shown). A continuous record of any one channel may be obtained by setting the selector 383 to HLD. The programming circuits comprise mainly metal oxide semi-conductor field-effect transistors known as MOSFETS. Reference has been directed by the Comptroller to Specification 1229757.
