Title: Improvements in or relating to bale-handling attachments for tractors
IPC: B60P1/02
Filed: 1963-10-07
Abstract: 1,059,533. Tractor attachments for lifting bales. W. I. M. PERRY. Oct. 30, 1964 [Oct. 7, 1963], No. 39370/63. Heading B8H. A ram E<SP>1</SP>, Fig. 2, which moves a movable arm D<SP>1</SP> of a bale-lifting attachment for tractors towards a fixed arm D is mounted outside the arms on a bracket C<SP>3</SP> so that more bales may be accommodated between the arms. The bales are gripped laterally and the device may be attached to the front loader arms B of a tractor or the rear carrier or it may incorporate lifting means which may be secured to fixed points on the tractor. The arm D<SP>1</SP> is withdrawn by a spring F. Bale retaining side and end rails D<SP>3</SP>, D<SP>4</SP>, C<SP>4</SP> are provided. The side of the device bearing the arm D<SP>1</SP> is resiliently mounted on the tractor by a pin H, Fig. 5, which slides in vertical slots C<SP>5</SP> in members C<SP>1</SP>, C<SP>2</SP> and is attached to the member C<SP>1</SP> by a spring H<SP>1</SP>. When a load of bales is lifted the spring H<SP>1</SP> is compressed as the slots C<SP>5</SP> move downwards with respect to the pin H. This causes the lifter to tilt slightly so that the bales rest against the side rails D<SP>3</SP>. In a modification, Fig. 6, the movable arm comprises a part J<SP>1</SP> pivoted to a part J which is pivoted about the point J 2  on the frame by a ram E<SP>1</SP>.

Title: Improvements in refrigeration equipment
Inventor: MILLER ALLAN SINCLAIR
IPC: F25B40/00
Filed: 1959-11-20
Abstract: 934,490. Refrigerating. DENCO MILLER Ltd. Nov. 3, 1960 [Nov. 20, 1959; Feb. 17, 1960], Nos. 39478/59 and 5668/60. Class 29. In a compression refrigerating system a heat exchange vessel 6 large enough to hold all of the refrigerant charge in liquid form and heated at its lower portion by the compressor discharge is included in the suction line. The vessel 6 ineludes a perforated baffle 8 (Fig. 2) which prevents refrigerant vapour entering the vessel from the evaporator 3 from coming into contact with the compressor outlet line 7, which is coiled within the lower portion of the vessel, while allowing liquid refrigerant from the evaporator to contact and be evaporated by said coils. For defrosting the evaporator 3 the expansion valve 5 is provided with a by-pass line controlled by a solenoid valve 13 which is opened when necessary to supply liquid refrigerant to the evaporator, this liquid refrigerant being evaporated in the vessel 6. The refrigerating circuit also includes a liquid reservoir 4 and a small bore oil return line 10 leading from the bottom of the vessel 6 to the compressor.

Title: Acoustic holography system
IPC: G03H3/00
Filed: 1972-08-24
Abstract: 1408047 Acoustic holography THOMSONCSF 24 Aug 1972 [27 Aug 1971] 39570/72 Heading H4D Ultrasonic frequency acoustic energy used to form an acoustic hologram of an object is modulated at a much lower frequency so that speckle in an optically reconstructed image of the object is made less objectionable. In the system shown the object 1 is immersed in a liquid-filled tank 7 having acousticallyabsorbing wall-linings 6. An object beam from transducer 10 is directed on to a hologram detector cell 13 by mirrors 8, 11, 12 and interferes with a reference beam from transducer 17. The cell 13 includes an oil film 15 supported by a membrane 14. Pulsed or continuous wave energy of, e.g., 5 MHz carrier frequency is provided by generator 19 and is amplitude-modulated or frequency-modulated (e.g. through a 100 kHz sweep at a recurrence frequency of 30 Hz) by generator 20. The hologram formed in oil film 15 is reconstructed by diffraction of coherent light from the film surface, the light then passing via stop 129 and prism 29 into a camera tube 30 feeding a television display 31. The light may be chopped in synchronism with pulsing of the ultrasonic energy. The effect of the low frequency modulation is to "smooth out" the speckle by changing its distribution, without appreciably blurring the image. The movements of the speckle are not seen because of the integration properties of the target of camera tube 30 and because of retinal persistence of the eye.

An aircraft structural assembly incorporating means for removing boundary layer air therefrom comprises a pair of spaced sheet members parallel to one another and embodying passage means rendering said sheets pervious to the passage of air therethrough, a plurality of further members secured in fluid-tight relation to a surface of one of said sheets and providing tributary ducts, each having at least one nozzle adapted to meter the flow of air from the ducts and hence control the flow of boundary layer air through the said passage means. As applied to an aircraft wing, each wing panel comprises inner and outer assemblies 12 and 14 secured to stringers 16, 17, the assembly 14 comprising a conventional cellular core panel which forms one wall of main suction air ducts 18. The assembly 12 comprises a conventional cellular core panel 19 and inner and outer plate members 22 and 23. Rows of bores or passageways 24 are provided in panel 19 for the flow of air therethrough into tributary ducts 41 which may be individual or continuous as shown, and are formed with nozzles 43 which meter the air-flow into ducts 18. Strips 26 bonded to plate 23 are spaced to form chambers 27 which communicate with apertures 29 formed in an outer skin 28. By this means boundary layer air is drawn through apertures 29 and delivered through nozzles 43 to ducts 18 in metered quantities.

A resist image may be produced by (4) exposing the photo-resistforming layer imagewise to actinic radiation, (5) stripping the film support from the resulting imagebearing layer, steps (4) and (5) being effected in either order, and (6) removing areas of the layer imagewise to form a resist image on the surface having raised areas. Areas on the surface which are unprotected by the resist image may then be treated with a reagent capable of etching the areas or depositing a material on the areas. The photoresist-forming layer may be a negative-working material, the unexposed areas being removed and exposed areas remaining as the resist image, or a positive-working material, the unexposed areas forming the resist image.

Sheet separators.-Sheets are separated in succession from the pile by the wheels 44 rotated by a D.C. motor and fed through guideways 18, 14 to a photo-electric detector 28, 30 which controls the torque of the motor in such a way that the first sheet is separated with high torque until its leading edge reaches the detector, whereupon the torque is lowered and remains low unless a given time elapses, after a sheet has cleared the detector, sufficient to allow the next sheet to reach the detector, without a further sheet reaching the detector, in which case the torque is restored to high. Preventing double feed.-Extra sheets are prevented from being separated, first by a reversely rotating roller 74 and secondly by a ridged polyurethane belt 96 reversely moving against a feed wheel 80. The speed of the wheel 80 is detected by a photo-electric device and a rotating slotted disc, and the pressure of the belt against the wheel 80 is adjusted by rollers 108, 110 whose position is controlled by a solenoid 116.

An elastic sealing ring 4 of rubber or plastic material is inserted into an internal groove 13 of, for example, a tubular connecting sleeve 12 by deforming the ring to create radially-inward bends. re-forming the bends into axial bends pointing in the same direction, bringing the ring into position radially-inward of the groove and pressing the ring outwardly into position within the groove. Sealing rings 4, Fig. 1, are fed one at a time into a notch 5 of a guide member 1 ready for insertion. After the head 7 of a pushrod 6, which is slidable in a sleeve 8, has been pushed through the centre of the ring 4, Fig. 2 (not shown), pins 11 or streams of compressed air, Fig. 6 (not shown), force opposite sides of the ring radially-inward to reduce the diameter of the ring to that of the bore 2 of the guide member. Bosses 9 on the push-rod then reform the direetion of the bends and cause the ring to move towards the groove 13 as shown in Fig. 3. After the ring has been moved to the position radially-inward of the groove, Fig. 4 (not shown), the push-rod is started on its return stroke and the head 7 co-operates with the end of the sleeve 8 to press the ring into place. In a modification, the sleeve 8 is brought up to co-operate with the head 7 to press the ring into place. The ring may be of round or square cross-section. Moreover, more than two bosses or shoulders 9 may be employed.
