Filed: 1938-03-07
Abstract: 495,614. Window fastenings. SMITH, F. C. March 7, 1938, No. 7075. [Class 44] A fastening for securing sliding window sashes in closed or partly open position comprises an upstanding plate secured to the meeting rail of the upper sash and provided with. a slot B and apertures B<1>, B<2> engageable by a bolt secured on the lower sash rail. As shown, the bolt has an operating knob C<3> which can be turned into lateral slots C<2> in the barrel to hold the bolt withdrawn or shot and an aperture D<2> which, in the shot position, registers with apertures C<3> in the barrel to receive the shackle of a padlock, or a securing pin. Apertures B<2>, B<1>, B receive the bolt to secure the window in closed position, partly open position, and position allowing limited opening movement respectively. An apertured and slotted' pillar with attached screw for screwing into the rail may replace the plate. Alternatively, a strip of metal bent to inverted U-form with parallel limbs and out-turned extremities to form feet with attaching screw apertures may replace the plate, the bolt engaging between the limbs. Cross-bars riveted to the limbs define the bolt-receiving apertures and slot. As an alternative to the barrel, a short length of tube secured in line with a screw-eye may be used.

Title: Improvements in or relating to electric converting circuits
IPC: H02M7/62
Filed: 1954-03-11
Abstract: 750,543. Converting. TELEFUNKEN GES., [formerly TELEFUNKEN GES. FUR DRAHTLOSE TELEGRAPHIE]. March 11, 1954 [March 11, 1953], No. 7075/54. Class 38 (2). During the initial period of vibration of the reed 1 of a vibratory converter suitable for supplying radio apparatus with high voltage from a car battery through a rectifier 12, sparking at the contacts is reduced by an inductor 3 connected in the output of the battery 2, the effect of the inductor in reducing the current supplied decreasing after the initial period as current from the rectifier is supplied to a premagnetizing winding 18. The vibrator output voltage is stepped up in transformer 6 having a secondary winding 10 tuned with condenser 11 to the output frequency, rectified at 12 and supplied to storage condenser 13, loads being supplied at 14, 15. These may be respectively the last valve, and the preceding valves of a valve amplifier. The inductor 3 is effectively removed from the circuit after the initial period by being saturated by direct current through winding 18 which may be the load current delivered at 15, or current drawn directly from across the output terminals of rectifier 12. Sparking is normally reduced by damping resistors 7, 8, 9 on the primary side of transformer 6, and at the end of the initial period by tuning the inductance of winding 18 by a condenser 19.

Title: Steel rope railway installations and like conveying devices
IPC: B61B7/02
Filed: 1948-03-08
Abstract: 670,237. Rope railways; marshalling vehicles; terminals for overhead ways. DACHKEVITCH, V. March 8, 1948. No. 7138/48. Classes 78 (ii), 78 (iv) and 104 (ii). A rope railway comprises a pair of parallel steel ropes 1, 2, Fig. 1, located in a horizontal plane above a similar pair 3, 4, providing forward and return tracks for waggons 6 which are propelled along their respective tracks by an endless traction cable 7 common to both. An elevator is provided for transferring the waggons from one track to the other. The waggons are each provided with means operated automatically to cause them to grip or release the traction rope. The upper and lower track ropes are fixed at one end and tensioned at the other by weights 12, 11 respectively, and aligned with fixed lengths of continuation track rails 29, 39 at both ends. The waggons each comprise a container or bucket 18, Figs. 3 and 4, located within a frame 19 and arranged to be tilted upwardly therein at one end. In its lower position the bucket bears upon a pair of pivoted tong-like arms 26 pivoted on the bottom of the frame, thereby closing jaws 27 upon the traction rope 7. A waggon is supported upon the track ropes 1, 2 or 3, 4 by pairs of wheels 22 mounted on bogies, the bogies 23 at one end being mounted directly on the bucket 18, one on each side, whereas the bogies 24 at the other end are mounted one on each side of the frame 19. At the last mentioned end the bucket also carries two auxiliary wheels 28, each on an axle projecting laterally through a vertical slot in the side of the frame 19, so that when these wheels ride upon cam rails 29d located in their path, the end of the bucket is lifted relative to the frame, which is held against movement by its bogie wheels engaging beneath a horizontal abutment rail 29c. The pressure on the arms 26 is thus released, so that the jaws 27 are opened by spring pressure and the waggon is disengaged from the rope 7. Fig. 6 shows an elevator or hoist for lowering a waggon 6 from an inclined rail 29 at the end of the upper rope track on to the end rail 39 of the lower track, the waggon being arranged to strike an abutment 30 and automatically start the lowering mechanism. The cage 32 descends until its outer end is stopped by a buffer 37, whereupon it tilts until the other end meets a buffer 38, the waggon-supporting rails within the cage being then aligned with the end rails 39 of the lower track. The waggons may be loaded automatically by an auxiliary system comprising a fixed track located above the upper rope track 1, 2 and carrying a hopper truck 41, Fig. 7 (not shown) driven at the same speed as the waggons, so that after being filled at a loading station the hopper travels along above the waggon while unloading into it. Automatic means may be provided for opening the bottom of the hopper and for closing it during the return to the loading station.

Title: Improvements relating to the creaming of biscuits and the like
IPC: A21C15/02
Filed: 1927-03-15
Abstract: 292,654. Snell, L. March 15, 1927. Coating bakers' and confectioners' goods.-Biscuits and the like are coated with plastic material such as cream, by depositing a number of individual pieces of cream on a conveyer and dropping a biscuit on each piece whilst it is still on the conveyer. As shown, pieces of cream are deposited, on a conveyer 2, from a hopper 1 by a reciprocating slide 3 and a rising and falling member 4 in known manner. The biscuits are dropped from a magazine 6, being released one at a time by a reciprocating slide 7. A cooler 8 sets the cream prior to the passage around the pulley 9. The coated biscuit is then detached from the conveyer 2 by a stop 11, and falls in inverted position on to a conveyer 10. After the cream is heated by the heater 12, a cover biscuit 14 is applied. The sandwich biscuit is then conveyed away for storage or package. According to the Provisional Specification, the conveyer makes a sharp turn downwards to strip the coated biscuit therefrom, or the conveyer may be made of linked plates which are heated at a certain point in their paths to facilitate the stripping of the coated biscuit from the conveyer.
