Title: Improvements in or relating to mixing machines
IPC: B29B7/72
Filed: 1957-07-29
Abstract: 864,917. Mixing. BRITISH UNITED SHOE MACHINERY CO. Ltd. July 29, 1957 [July 31, 1956], No. 23881/57. Class 86 A mixer for viscous substances, such as are used in the preparation of polyurethrene foam, comprises a mixing screw in a chamber, and the screw is adjustable into either of two positions, one for normal working and the other a position in which it scrapes the walls of the chamber to remove residue when the operation is completed. The mixing screw is driven through a pulley 160, Fig. 1, by a motor 156 and the fluids to be mixed are fed through pipes 120, 124 by pumps 28, 30, which draw from containers 24, 26. The pumps are driven through gear reduction units 70, 88, the former being driven direct from a shaft 56 while the latter is driven through an adjustable ratio V-pulley device 96 so that the relative proportions of the constituents can be adjusted. A motor 32 drives the shaft 56 through an electromagnetic clutch 58 and the shaft is also provided with an electro-magnetic brake 60, which locks the shaft while the clutch is disengaged. The speed of rotation of the shaft 56 is adjusted by an adjustable cone pulley drive 36, the whole motor assembly 32 being slidably mounted on guides 34 to permit this adjustment. The mixing screw 162, Fig. 2, has a spiral vane 164 of conical configuration to cooperate with the inner surface of the chamber 166. When a lever 194 is moved towards the right, a rod 202 and the lever 206 are drawn down to lower the spindle 150 and thus bring the mixer 162 substantially into contact with the chamber wall, so as to scrape material therefrom. At the same time a lever 232 thrusts a gate 178 towards the right to close the outlet 184 and cut off any adhering material. The position of the screw 162 when raised for mixing is set by means of an eccentric stop 226 against which the lever 206 abuts. Material is fed into the mixing chamber 166 through nozzles 122, 126, the former of which is controlled by an electro-magnetically actuated valve 130. After the two motors have been switched on the lever 194 is moved to the left but its initial movement is retarded by a dashpot device 292, so that the discharge orifice 184 is not opened until a working quantity of material has accumulated in the mixing chamber. The movement of the lever 194 opens the outlet by moving the gate 178 and also actuates switches which bring an automatic timer into operation and cause engagement of the electro/magnetic clutch 58, Fig. 1, in the main drive, so that the pumps start feeding the materials, and open the supply valve 130, Fig. 2. Mixing then proceeds until the timer automatically switches off the pumps.

Abstract: 769,544. Stapling. SPEED PRODUCTS CO., Inc. Aug. 28, 1953 [April 20, 1953], No. 23885/53. Class 89 (3). In a pneumatically operated pistol-like stapling device, staple blanks from a roll R are bent to staple form by a forming blade F which co-operates with anvil portions AH of a bending block BB slidable in a pivoted base CC, and are then driven by a driving blade DB. The base CC is held closed by a spring- pressed sliding latch LT thereon engaging with notches N in a keeper K carried by a fixed housing S. The blades F, DB co-operates with lips L on the block BB which normally extend across a guideway FG for the blades and project through slots 32 in the housing S, so that the anvil portions AH are withdrawn against a spring 105 as the staple is formed and driven. The staple blanks are fed forwards by spring-pressed pawls P pivoted on a cylindrical portion C of the device or on a container SBC for the roll R which is held in position by a spring strip ST engaged with a bar 136 at the rear end of the base CC. Feeding is effected by portions 83 of the pawls cooperating with spring tongues 92. Retrograde movement of the staple blanks is prevented by a spring-controlled rockable member GB. The blades F, DB are carried by outer and inner portions FP and SDP respectively of a double piston slidable in the cylinder C and operated by air under pressure from a chamber 23 under the control of a triggeroperated valve V. The outer piston FP moves downwards against a spring 155, the inner piston SDP remaining stationary, until the outer piston clears a fixed rubber sealing cup 28, and thereafter the inner piston SDP moves downwards. The container SBC forms the subject-matter of Specification 769,545.

Abstract: 971,797. Hydrostatic transmissions. DOWTY TECHNICAL DEVELOPMENTS Ltd. Sept. 16, 1963 [June 22, 1962], No. 24096/62. Headings F2C and F2D. [Also in Division F1] A hydrostatic power transmission 16 is combined with an engine 2 to form a unit having an overall length not substantially greater than that of the engine itself, the power output shaft 29 being connectible to the engine by a double-acting clutch 36 either mechanically through shaft 23 or through the hydrostatic transmission 16. The crank-shaft 3 drives shaft 23 and pump shaft 19 of the transmission 16 through gears 22, 21 and the motor shaft 26 of the transmission 16 is geared to a pinion 3 freely rotating on the output shaft 29, the clutch sleeve 36 being splined to shaft 29 and movable to the left to clutch shaft 23 directly to shaft 29 or to the right to clutch pinion 33 to shaft 29 to transmit the drive through transmission 16. The sleeve 36 and transmission control member 40 are actuated by a single lever 41, Fig. 2, moving in a gate 50. In the midposition of slot 50, lever 41 sets the lever 40 to neutral position, movement to the right selecting reverse drive while movement to the left to the end of the straight portion of slot 50 sets lever 40 to the maximum forward transmission ratio, at which the speeds of shaft 23 and gear 33 are equal. Lever 41 can then be moved along the bar of slot 50 to rotate shaft 44 which actuates the lever 37 to move sleeve 36 into engagement with shaft 23 for direct drive, a spring bias on lever 41 then automatically moving it to the end of the short portion of slot 50 to set lever 40 to neutral so that no power is transmitted through transmission 16. On return to drive through transmission 16, lever 41 must first be moved to the maximum forward transmission ratio to bring pinion 33 up to the same speed as shaft 23 before it can be moved sideways to shaft clutch 36. Specification 962,361 is referred to.

Title: Antenna
IPC: H01P1/19
Filed: 1960-07-12
Abstract: 881,489. Aerials. HUGHES AIRCRAFT CO. July 12, 1960 [Nov. 2, 1959], No. 24318/60. Class 40(7). An aerial suitable for use on aircraft comprises a waveguide, a plurality of radiating means, and a -ferrite and control means for each radiating means. In a first embodiment the waveguide 12 has a number of slots 32 (only 32D shown) along the length. A powerabsorbing load is placed at the end 20 of the guide. A core 38 is mounted in the guide, the core being either a continuous cylinder of ferrite or a number of short lengths of ferrite having non-ferrite sections between them in the region of the slots. Coils 36 are wound about the guide between the slots, and each coil with its associated section of ferrite forms a field rotating means. By varying the current in a coil the degree of field rotation may be varied so that degree of radiation from the following slot is also varied. The coil 34H allows rotation of the field such that there is no undesirable reflection from the power absorbing load. By adjustment of the currents in the various coils. 36 the radiations from the slots may be combined into a beam. To permit steering of the beam an auxiliary waveguide 44 is associated with each slot 32, each guide 44 having a ferrite core 46 (only 46D shown) and a coil 44. Change in current in a coil 44 causes change in phase of the radiated energy, so that by control of the current in all the coils 44 the beam may be steered in any direction in the plane of the slots. Further aerials of the form described above may be added, as exemplified by the second guide 14, thus enabling the beam to be steered in more than one plane. In a second embodiment, Figs. 2 and 3 (not shown), the waveguide is bent into a circle, the auxiliary guides lying on radii, and commutator means is provided for distributing current to the coils on the main and auxiliary guides. In this way the radiated beam is rotated at the speed of the commutator and by stacking the guides steering of the beam in two planes is possible.
