Title: Combined pallet and crate structure
IPC: B65D19/08
Filed: 1949-05-12
Abstract: 659,148. Crates. TRIGGS, W. W. (Tri- State Engineering Co.). May 12, 1949, No. 12727. [Class 18] [Also in Group XXX] A combined load-handling pallet and crate structure comprises a pallet having a deck, vertical crate walls carried by the deck, legs for the deck, and floor bars connecting the lower ends of the legs and having vertically extending recesses near their ends, which recesses are adapted partly to embrace the upper edges of crate walls upon which the pallet is stacked to prevent horizontal shifting of the pallet on the walls. The deck of the pallet shown, comprises transverse rods or heavy wires 11 welded to longitudinal rods or wires 10 and is reinforced by relatively heavy rods 12, 13, welded to the upper and lower sides of the ends of the rods or wires 11. U- shaped legs 14 welded at their upper ends to the rods or wires 11 are joined by floor bars 15 arranged in pairs near the longitudinal edges of the pallet and bent back at the ends as shown at 17 for welding to the deck. Bends 16 in the bars 15 are adapted to receive the walls of a lower pallet on which the pallet is stacked. Sheet-metal floor bars 18 extend between the bars 15 to which they are welded. Side walls formed of rods or wires 21, 22 welded together are hinged together by spiral wires 25 so that when removed from the pallet they fold flat. L-shaped hooks 26 welded to the side walls have outwardly extending portions 27 which may be engaged under the outer rods 10 or 11 by bending the latter and serve to secure the walls to the deck. In a modification the portions 27 have upwardly bent outer ends and the hooks are disposed midway between the legs 14. In another modification the hooks are replaced by downwardly projecting U-shaped members on the walls adapted to pass between the rods or wires 10 to be secured by removable retaining members.
Patent GB-641090-A (GB)
Title: Improvements in or relating to extruded thermoplastic tubing and production thereof
IPC: B29C53/78
Filed: 1947-05-12
Abstract: <PICT:0641090/IV (a)/1> <PICT:0641090/IV (a)/2> Tubing is formed from an extruded thermoplastic strip, Fig. 3, with a bead 4 along one edge so that on winding helically round a mandrel 6 the rib 4 overlaps the edge of the strip 3 and is bonded thereto.  Materials mentioned include vinyl polymers, polymerized vinyl acetate, polyethylenes and nylon resins.  If the tubing is formed immediately after extrusion of the strip 3, the temperature is sufficient to cause bonding under the pressure of the winding action, but a cement or a solvent may be used for the bonding. For large diameter tubes the strip may be formed with a bead 4 along one edge and one or more beads along the length of the flexible part 3 of the strip.  The beads, which may be formed on the inside of the tubing, may be semi-circular, preferably with a hollow core 41, Fig. 3, or they may be triangular.  The Specification as open to inspection under Sect. 91 comprises also tubing formed from a strip having flexible parts 23, 24, Fig. 11 (Cancelled), and an annular rib 25.  Tubing may also be formed from a flat strip wound helically on a mandrel with the edges overlapping to form the reinforcing rib.  This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to vehicle wheel mounting assemblies
IPC: B60G11/14
Filed: 1955-05-03
Abstract: 779,305. Steering vehicles. HOLMES, T. S. May 3, 1955 [May 3, 1954], No. 12778/55. Class 79(5). [Also in Group XXXII] A vehicle wheel mounting assembly comprises a vehicle wheel mounting rotatably carried on a substantially horizontal axle, means supporting the axle for swinging movement about an axis fixed with respect to the vehicle frame and inclined fore and aft as well as laterally of the vehicle, steering knuckle means mounted for rotation about the axis, the axle supporting means being adapted for axial translation along the axis towards and away from the vehicle frame, and a resilient coupling between the steering knuckle means and the axle supporting means to resist the translation and swinging movement of the axle supporting means. As shown in Figs. 4, 5 and 9, for a dual wheel assembly in which the mounting and support means are the same for each wheel, and in which each wheel is carried on a stub axle 24, the latter is formed integral with a journal 25 which is rotatably and slidably carried on a king pin 27. The upper end of the king pin 27 is secured in a socket portion 28 of a swivel body 29. A compression spring 29a is anchored in the journal 25 and in a steering knuckle bearing 30 which is rotatably carried by the portion 28, the spring being enclosed in a telescopic housing 34, 35 which, during suspension movements of the wheel, functions in part as a pneumatic shock absorber. An arm 40 is adjustably clamped to the bearing 30 and the arms 40 of the two wheels are tied together through universal joints 42 by a rod 43. The arrangement is such that an optimum tracking force is provided on each of the wheels as the vehicle is towed or pushed along a given course and that vertical movement of one wheel relative to the other is taken up by a slight winding or unwinding of the springs 29a. The swivel body 29 may be rotatably carried on a fixed base 50 secured to the vehicle frame or by a non-swivel base rigidly attached to the vehicle frame. The body 29 may be locked by a manually operated spring-loaded plunger 57 which engages notches 58 on the base 50 and which is so arranged that the body 29 over-rides the plunger 57 if more than a predetermined rotational force is applied thereto. In the arrangement according to Fig. 8 (not shown) the plunger can only be withdrawn manually. In another arrangement, Figs. 11 and 12 (not shown), a single wheel mounting is secured to a fixed base on the vehicle frame, a tie-rod corresponding to rod 43 above, extending across the vehicle frame between the two mountings. In the arrangement according to Fig. 14, a hinged tow-bar 72 is pivotally connected to the vehicle frame 19 and to the mid point of a tierod 69 between single wheel mountings to permit controlled steering of the wheels. A similar arrangement may be employed for the dual wheel mountings of Fig. 4. In another arrangement, Fig. 13, the steering knuckle 30 is replaced by a collar 80 which is pinned to the king pin 27 whereby the spring 29 resists rotation of the stub axle about the king pin.

Title: Improvements in hop picking machines
IPC: A01D46/02
Filed: 1955-05-05
Abstract: 834,881. Hop-stripping machines. BURR, E. H. Aug. 3, 1956 [May 5, 1955], No. 13067/55. Class 6(3). In a hop-picking machine, all the material which has been stripped from the hop vine is fed via a hopper 1 on to a conveyor 2, so formed that loose leaves and hops fall on to a second conveyer 3 while the lateral stems are conveyed to the stripping section of the machine. The stripping section comprises two stripping belts 6 and 7, the upper one 7 being driven in such a direction as to feed the lateral stems into the passageway between the two belts. The lower belt 6 may be driven slowly in the same direction as the upper one, drive being transmitted to it in this case from the upper belt through the lateral stems being stripped, or it may be driven in the opposite direction by means of the engine 8, or be caused to remain stationary by means of a brake. The hops stripped off the lateral stems fall on to the conveyer 3 and are carried to a cleaning device, whilst the stripped laterals are discharged from the machine by the conveyer 17. In a modification, the upper belt 7 is replaced by a series of drums rotatable about horizontal axes, the stripping fingers being carried on bars which are located inside the drums so as to project through slots in the periphery of the drums. The machine may be adapted for stripping hop vines by enlarging the dimensions of the stripping assemblies.

Title: A system for controlling the frequency of oscillators before operating in synchronism, particularly radio diffusion emitters on communal wave lengths
IPC: G01R23/00
Filed: 1946-04-30
Abstract: 611,548. Frequency measurements; synchronism indicators; cathode-ray oscillographs. SOC. FRANCAISE RADIO-ELECTRIQUE. April 30, 1946, No. 13081. Convention date, Nov. 4, 1939. [Class 37] Synchronism of two or more high-frequency oscillators is checked by feeding voltages from each of the oscillators, or voltages resulting from the mixing of these voltages, to a cathoderay oscillograph which is so connected that a stationary image is obtained on its screen when the transmitters are in synchronism, the image rotating in one direction or the other if the frequency of one transmitter differs from that of the other. A pilot station 1, having a wavelength 'corresponding to a frequency Fo=959,000 cycles per second, is connected by a telephone line 2 to a station 3 to be checked. A frequency divider 4 having a ratio of 1/728 converts the frequency Fo to a frequency fo=Fo/728=1317.3 which can easily be transmitted by the line. At the other end of the line 2 the telephone current at frequency fo is passed through amplifiers 5, 6 and stabilizers 7, 8 and thence to a frequency multiplier 9 having a ratio of increase slightly different from the ratio of decrease of the divider 4, e.g. 729, which is the sixth power of 3 and is obtainable by six successive treblings. The value 728 is obtained therefrom by subtracting one unit. The amplifier 6 supplies two-phase voltages at the frequency fo to the two pairs of deflecting plates of a cathode-ray oscillograph 11, causing the spot to describe a circular trace. The checking voltage from the pilot station 1, after conversion to the frequency Fo+fo, is fed to a mixer 12 at the same time as a frequency Fo+# from the transmitter 3 to be checked, e corresponding to the possible frequency difference between the transmitters 1, 3. The output from the mixer 12, at a frequency of fo - # is fed to a gas-filled tube giving short impulses at the same frequency which are supplied to the anode 13 of the oscillograph and produce an instantaneous increase in the diameter of the trace visible as a notch 14. This is stationary if the frequencies of the stations 1, 3 are identical, but rotates in one direction or the other if these frequencies differ and the frequency of the station 3 may be corrected.

Title: Method and apparatus for printing colour transparencies
Inventor: KENNINGTON ARNOLD REGINALD
IPC: G03B27/73
Filed: 1961-04-12
Abstract: 927,727. Colour printing. ILFORD Ltd. March 29, 1962 [April 12, 1961], No. 13200/61. Class 98 (1). Colour transparencies are printed on coloursensitive material by effecting three exposures of the transparency through red, green and blue filters such that two of the three exposures begin concurrently and the third exposure begins at the end of one of the other two exposures; the total amounts of red, green and blue light transmitted being controlled by a corresponding red, green and blue coloursensitive photo-electric cell. In the Figure, three light sources 4, 5 and 6 are provided with red, green and blue filters. The exposure time of lamp 5 is controlled by a tiltable semi-silvered mirror 7, the movement of the mirror being controlled by solenoid 8, the exposure of lamp 6 is controlled by shutter 11 operated by solenoid 12 and the exposure of lamp 4 is controlled by tiltable mirror 10 operated by solenoid 9. Light from the three sources passes through transparency 1 and is split by beam splitter 14 to printing material 15 and further beam splitters 18 and 19 dividing the light to three photoelectric cells 20, 21 and 22 provided with appropriate filters. Firstly, the two lamps 4 and 5 are switched on and when the light from lamp 5 reaches a certain value, solenoid 8 is energized causing mirror 7 to be tilted so that light from lamp 6 is directed towards condensing lens 3 and so that light from lamp 5 is not directed towards lens 3. Similarly when sufficient light from lamp 4 is emitted, solenoid 9 is energized causing mirror 10 to be tilted and when sufficient light from lamp 6 is emitted, solenoid 12 is energized closing shutter 11. Alternatively, mirror 10 may be fixed and a shutter be placed in front of lamp 4.
