Title: Radio receiver/emitter station
IPC: G01S13/84
Filed: 1977-05-26
Abstract: 1536094 Frequency control ELECTRONIQUE MARCEL DASSAULT 26 May 1977 [3 June 1976] 22318/77 Heading H3A In a transmitter-receiver of a carrier wave modulated by an auxiliary carrier wave, both the carrier wave and auxiliary carrier wave as transmitted are derived from first and second voltage controlled generators 23, 26 in respective control loops 62, 61, so that the phases of the transmitted carrier and auxiliary carrier are controlled by the corresponding phases in the received signals. The received carrier of hyper-frequency # 0 , and phase modulated with a H.F. carrier of frequency f is mixed with a locally generated signal of carrier frequency # 0 p/p+q, amplitude modulated at the H.F. frequency, the mixed signal at I.F. frequency # 0 q/p+q having an I.F. amplitude corresponding to the phase difference between the H.F. components, as received, and as locally generated by VCO 26. Filter 45 passes the signal at the frequency # 0 q/p+q to phase comparator 38, whose other input is derived via multiplier 29 from the local generator 23, a VCO. The resultant error signal controls the phase of the signal from VCO 26. An amplitude modulated signal of carrier frequency # 0 q/p+q is locally generated by means of the VCO's 23 and 26, a phase comparison between the latter signal, and the I.F. signal at 39, providing an error signal controlling the phase of the signal, of frequency # 0 /p+q from the VCO 23. The outputs of the VCO's 23 and 26 are processed at 71, 75 and 73 to provide the transmitted phase modulated signal. The transmitter-receiver is used in a radio-ranging arrangement.

Abstract: 978,634. Injection moulding. SCHLOEMANN A.G. June 12, 1962, No. 22483/62. Heading B5A. An injection moulding machine has one mould half 12, Fig. 1, attached to a fixed platen 6, the other mould half 13 attached to a movable platen 11 which slides on guide columns 4 and is attached by means of a pressure pad 10 to a closing plate 9, and hydraulic means 14 for locking the closing plate 9 on the guide columns 4. In one embodiment (Fig. 2), the locking means consists of clamping bushes 15 mounted on the guide columns so that there are chambers 17 between the clamping bushes and the guide columns into which hydraulic fluid may be introduced to force the damping bushes against the inside of the bores in the closing plate 9. In the other embodiment (Fig. 4), clamping bushes 22 are mounted inside the bores of the closing plate 9 to leave chambers 24 into which hydraulic fluid may be introduced to press the clamping bushes against the guide columns. The pressure pad 10 for exerting the mould closing pressure, and the clamping bushes 15 or 22 are operated by the same hydraulic system, but in the case of the clamping bushes there are included pressure transformers 20 or 26 so that a higher pressure may be applied to the clamping bushes than to the pressure pad 10. The clamping bushes 15 are slipped on to portions of the guide columns of reduced radius and are held on by sleeves 16 screwed on to the guide columns. The clamping bushes 15 may also be screwed on with square-section threads (Fig. 3, not shown). The clamping bushes 22 are mounted in a similar manner and are held on by sleeves 23. In another embodiment the pressure pad 10 is replaced by pressure pads acting between nuts on the ends of guide columns and the outside face of the fixed platen. These pressure pads act against the force of springs mounted at the other end of the guide columns.

Abstract: 844,724. Axial-flow fans. HUDSON ENGINEERING CORPORATION. July 15, 1958, No. 22623/58. Addition to 843,995. Class 110(1). Sockets 14, Fig. 2, bolted to a fan-hub 15, each receive the shank 13a of a fan blade. Each blade, after adjustment of its pitch, is fixed in position by means of screws 38 which forces the blade radially outwardly so that a shoulder 31 on the blade shank tightly engages retainer ring segments 32 which are housed in an annular groove in the corresponding socket 14. If necessary, one or more of the screws 38 may be tightened more than the others to adjust the position of the centre of the gravity of the blade. To remove a blade, the screws 38 are slackened off and the retainer ring segments 32 are prised from the annular groove, whereupon the blade can be tilted as shown until its tip is clear of a surrounding stationary shroud ring and then withdrawn. This procedure is reversed when inserting a blade. In addition to the annular groove in the socket 14, an annular groove for engaging the retainer ring segments 32 may also be formed on the shoulder 31. The retainer ring segments may be of conically-tapered form as shown in Fig. 6, to engage a similarly tapered shoulder 35a on the blade shank. When the blade shank is of plastics or other soft material, a metal ring 39, Fig. 2, or 47, Fig. 6, may be provided between the blade shank and the screws 38.

Title: Adjustable plate mould for continuous casting plant
IPC: B22D11/05
Filed: 1971-04-19
Abstract: 1346076 Continuous casting CONCAST AG 19 April 1971 [25 March 1970] 22991/71 Heading B3F At least one cooled side wall 3<SP>1</SP> and one cooled end wall 4 of a plate mould are adjustable and the end walls 4 (which are clamped by the side walls 3, 3<SP>1</SP>) are suspended from yokes 10 which rest on a supporting frame 2 of the mould. Cooling water is supplied to passages 7 in the mould walls and connections 22 convey water to and from the yokes 10 for the end walls 4. To increase the length of the cross-section the mould cavity 6, the side wall 3<SP>1</SP> is moved outwardly by cylinders 5 and the released walls 4 are moved apart by screw spindles or racks, or shifting devices attached to the tops of the  yokes and to the frame 2, or, as shown, by a cylinder 12 pushing apart levers (14) pivoted on the side walls 3, 3<SP>1</SP> and having forked ends (21) each embracing a necked end of a yoke 10. The yokes 10 have end blocks 10a slidable on ways 11 having T-slots 15 in which bolts 51 can slide or be tightened to hold the yokes in position. A wall 4 comprises a copper plate 31, Fig. 3, on a backing plate 32 with a T-slot 33 in which a block 34 grips the plate 32 until the spring- loading of bolts 40 attached to the block is overcome by the pressure of conical cam portions 43 of a screw spindle 42 axially movable in a wall holder 30. The latter is pivoted at 46 to the yoke 10 so that the inclination of the wall 4 can be adjusted. Springs 48 urge the holder 30 and its wall 4 towards the casting. An internal gauge is used when adjusting the size and taper of the mould cavity 6. The springs 48 co-operate with the gauge for taper determination until the end walls 4 are clamped. The screw spindle 42 also permits a movable backing wedge 50 to be interposed between holder 30 and a bearer 47 secured to the yoke 10. The wedge 50 may be replaced by eccentric discs in the frame 2. Instead of the screw spindle arrangement, a simple member (70) may be suspended by hook on the mould frame 2, behind a wall 4 to determine the latter's position and inclination. In addition to the thrust of the cylinders 5 on the side wall 3<SP>1</SP>, additional thrust to grip an end wall 4 may be supplied by hydraulic rams connected between the yokes 10 and the side wall. Alternatively, a beam (60) is hung from each yoke adjacent the outer face of the side wall to align with one edge of the respective wall 4 at the opposite face to apply thrust to the side wall, possibly by way of spacer (60<SP>1</SP>). The thrust is transmitted to the beam by a bridge piece (61), corresponding to the adjustment range (59) of the end wall, and carried by the rods (64) of rams (62) mounted on the frame 2. The thrust is developed by stacks of springs (63) acting between the frame 2 and the rod heads. The moulds are said to permit closer spacing in multiple strand casting machines.
