Title: Improvements in or relating to refuse-collecting vehicles
IPC: B65F1/14
Filed: 1948-10-01
Abstract: 687,564. Charging sealed refuse vehicles; raising and tipping bins. REY, F. Oct. 1, 1948. [Oct. 1, 1947 ; Sept. 27, 1948] Nos. 25598/48 and 25599/48. Class 78 (iv). The loading aperture of a refuse vehicle is sealed by a hood comprising sector-shaped parts 15, 34 pivoted at 23 to telescope into a fixed sector-shaped part 33 when engaged by a bin 3, Figs. 2 and 5, which is raised and tipped by a lifting cradle 1, 2. A closure plate on the telescoping hood is formed with an orifice 16 engaged by the mouth of the bin and normally closed by a flap 19 pivoted at 20 to the part 15 of the hood and operated by tooth gearing so that it automatically opens near the end of the inward movement of the hood and closes in the initial part of its outward movement. A hinged lid on the bin is opened and closed bv engagement of a hook 24 on the flap 19 with the handle 25 on the bin. The flap 19 is integral with a pinion 21, Fig. 6, engaging teeth on a segment 22 pivoted about the axis 23 and normally coupled to move the hood 15 by a spring pressed ball (not shown) on the hood which engages a recess 29 in the sector. As the bin 3 pushes the hood 15 and the segment 22 about the axis 23 the flap 19 remains closed until the segment 22 is arrested by a stop 31. Continued movement of the bin and hood then causes the pinion 21 to be rotated to open the flap 19 and with it the lid of the bin as shown in Fig. 5. During the reverse motion the flap 19 and the lid of the bin are closed when the segment 22 is held from movement with the hood 15, to which it is coupled by engagement of the spring passed ball within a further recess (not shown), by a rear stop 30. The hood 15 is mounted within a further hood 34 also pivoted about the axis 23 and moved by an abutment 37 engaging abutments 38, 38<SP>1</SP> on the hood 15. Inward movement of the hoods 15, 34 is limited by an abutment 35 on the hood 34 adapted to engage a stop 36 on a fixed hood 33. In an alternative construction the teeth on the segment 22 are replaced by a row of pins on an intermediate hood similar to the hood 34. The intermediate hood is coupled to the hood 15 by hook devices which are released to permit relative movement of the moving hoods when the intermediate hood is arrested by stops on the fixed outer hood. The cradle 1, 2 carries rollers 8 running in guides 9 at the rear of the vehicle. A hydraulic jack 12 pivoted at 10 to a bracket on the cradle and at 14 to the vehicle raises the cradle and bin until the upper roller 8 engages an abutment at the upper end of the guides 9. Continued operation of the jack 12 causes the lower rollers 8 to leave the guides 9 so that the bin and cradle tip about the axis 23 to bring the upper edge of the bin into register with the orifice 16 in the hood 15. The charging apparatus described may be manufactured as a fitting for attachment to existing vehicles.

Title: Improvements connected with power-operated presses
IPC: F16P3/04
Filed: 1944-12-22
Abstract: 587,973. Machinery guards. TAYLOR & CHALLEN, Ltd., and CHALLEN, H. D. Dec. 22, 1944, No. 25751. Addition to 585,632. [Class 80 (iv)] A modification of the mechanism according to the parent Specification for operating 'the braking device of a power press if the guard is not in position comprises a catch bar h which is raised or lowered by a bar b, which carries the guard at b<1>, through a toggle d, e, crank f and rod g. The raised position of the bar h corresponds to the safety position of the guard when the bar b is in position (1) and also to the full open position of the guard corresponding to position (3) of bar b, for tool setting. In these positions a catch h' on the bar h is clear of a tooth j<1> on a pivoted cam-operated lever j and a band brake q on the crankshaft m of the press is subjected only to a normal working pressure by a spring s. If the guard is left open, corresponding to position (2) of bar b, during normal working of the press the bar h is lowered and when the crankshaft m is rotated to effect a working stroke the tooth j engages the catch h' to move the bar h laterally to operate a cam lever n to apply an additional braking force to stop the press.

Title: A process for copolymerising unsaturated polyesters with monomers containing vinyl groups
IPC: C08F2/00
Filed: 1961-07-17
Abstract: Phenyl acetaldehyde, or a derivative thereof having alkyl, alkoxy or halogen substituents in the phenyl group, is used as a polymerization regulator in the copolymerization of unsaturated polyesters with monomers containing vinyl groups.  In examples the polyesters are derived from maleic and phthalic anhydrides and ethylene and diethylene glycols, the comonomer is styrene, and the aldehydes used are phenyl-, p-methylphenyl-, p-methoxyphenyl-, 2,4,6-trimethylphenyl- and p-chlorophenyl-acetaldehydes. Comparative data are given for copolymerization with benzoyl peroxide. The aldehyde may be stabilized with ionone in which case the gelling time of the copolymerization is longer. Specification 666,390 is referred to.

A polarized holding electromagnet having a spring-biased armature releasable to act on a circuit-breaker trip mechanism, has a yoke structure of symmetrical rectangular form affording duplicated magnetic circuits, one on either side of a central elongated core member which is common to both magnetic circuits and on which two spaced series trip coils are wound. The armature 30 is rectilinearly movable and is ' held, by flux from permanent magnets 19, 20, in engagement with faces 26 of two rectangular section polepieces 21 to bridge air gaps 29 in the duplicated magnetic circuits on either side of the core 13 which also houses the armature biasing spring 35. Air gaps between the polepieces 21 and magnetic end pieces 16 are set by non-magnetic shims 24. The housing 10 is dust-proofed by a diaphragm 41 secured around a guide sleeve 37 for the extension spindle 31, 36 of the armature which has a spring-loaded button 40 to allow for overtravel in resetting of the trip mechanism (not shown). The permanent magnets may be magnetized after assembly in the housing 10 of the electromagnet by temporarily connecting the coils 14, 15 in parallel and in opposition (Fig. 5, not shown). In an alternative arrangement (Figs. 6 to 8, not shown) soft iron shunts are provided so as to prevent demagnetization of the permanent magnets during an initial current surge in the coils 14, 15.

In a cycloconverter having an output of higher frequency than the input, groups of controlled rectifiers 1A, 2A, 3A and 1B, 2B, 3B switch portions of the supply waveform to opposite terminals of the output circuit and further rectifiers provide a return path to the supply. The supply for the arrangement of Figure (Provisional Specification 26733/63) has no neutral and the return from the centre tapped choke L4 across which is connected the resonant load C, Z is made via diodes D1 D2, D3. When line 1 is the most positive, 1A and 1B are fixed alternately to cause voltage swings in the output Z, the return being made by D2 or D3. As the voltage on line 1 falls the action is repeated with 2A-2B and so on to 3A-3B. In the arrangement of Fig. 2 the return path from the load is made by controlled rectifier 4A when 1A, 2A, 3A are conducting and by 4B when 1B, 2B, 3B are conducting. A neutral line may be connected to L3 (Fig. 1, not shown) so eliminating the diodes D1 . . . D3. The resonant combination of C and inductive load Z provides automatic commutation of 1A, 1B &c. Inductance L1 limits the peak current.
