Title: Silencers for sound waves transmitted by gaseous media
IPC: G10K11/172
Filed: 1948-09-07
Abstract: 656,924. Exhaust and like silencers. MAXIM SILENCER CO. Sept. 7, 1948, No. 23504. Convention date, Feb. 9. [Class 7(ii)] A silencer for sound waves transmitted by gaseous media has a gas passage which is inclined to the axis of a cylindrical casing 13 and has a pervious wall, the wall and the casing forming a resonating chamber, and the wall being formed of soundabsorbing material 31, such as copper or bronze wool, located between spaced shells 27, 28 held at their ends by spaced skew collars 22, 23 which permit removal of the wall endwise from the casing. The passage is bent where it passes through a hole in a partition 17 which, with further partitions 15, 16, sub-divides the resonating chamber. In Fig. 1 (not shown) the casing 13 and a similar casing are arranged before and after a casing containing perforated tube sections surrounded by copper wool, 'and a central part having holes connecting it with surrounding sound-absorbing chambers.
Patent GB-235386-A (GB)
Abstract: 235,386. Petter, G. B. June 12, 1924. Transfer-mechanism.-During the forward and effective stroke of the actuating- mechanism, levers carrying the transfer pawls are shifted so as to remove the pawls from engagement with the totalizer wheels. In the return strohe the pawls are prevented by detents from engaging and advancing the wheels, but if transfer is to take place the corresponding detent is displaced by the transfer pin to allow the transfer pawl to engage and, by spring action, to add unity to the higher wheel. The detent when displaced is temporarily held hy a latch which is subsequently moved to release the detent by the final advance of the transfer lever. Refirring to Fig. 1 which shows cne arrangement in association with the actuating- mechanism described in Specification 208,232, the transfer pawl 11 is pivoted at 10 to a leaver 8 mounted at 4 coaxially with the universal frame 3 adapted to be rocked downwardly by the actuating levers 27 and returned by a spring 7. The pawl is controlled by a spring 14 and its rocking movement on the lever is limited by a pair of stops 12 and a pin 13. On the return stroke of the actuating-levers the levers 8, unless otherwise prevented, would rise with the frame 3 and each pawl 11 would finally engage below a tooth 22 and advance the totalizer wheel 1 one step, the pawl and wheel mutually locking owing to the upper stop 12 coming in contact with the pin. Normally, however, the ascent of pawl 11 is prevented by a detent 15 which is controlled by a spring 19 and forms a stop in the path of the lug 20 integral with lever 8. When transfer occurs the transfer pin 2 rocks the detent 15 counterclockwise and the latch 17 pivoted at 18 is thereupon pulled to the right by the spring 19 and holds the detent displaced so that when the lever rises the pawl is unimpeded and performs its carrying function. The lug, by engaging the surface 26, then restores the latch and frees .the detent ready for the next operation. In modifications the pawl 11 is formed with a ring loosely encircling the axis 4 which thus serves to limit the rocking of the pawl on the lever 8 and the lever 8, detent 15 and latch 17 are of different form. In the arrangement shown in Fig. 4 the pawl 11 has its movements limited in one direction only by an overlapping lug 12 and the lever 8 carries also the latch 17 connected by the spring 19 with the detent. The latter is in two parts 15, 15<a> connected by a spring 19<a> and the arrangement is such that at transfer the part 15 after displacement by the transfer pin 2 returns with momentum sufficient to lift the part 15<a> by means of the abutment 15<c> and so free the lever 8.

Title: Improvements in battery plate grid casting machines
IPC: B22D25/04
Filed: 1951-10-10
Abstract: 737,375. Casting-machines. PINCOTT, J. S. Oct. 10, 1951 [Nov. 2, 1950], No. 23557/51. Class 83 (1). Extracting castings; heating moulds.-A machine for casting battery grids, wherein charges of molten metal are pumped into an openable mould, has means for preventing the pump from acting if the mould is not completely closed. The main shaft 17 of the machine is driven by a motor 20 through gearing 19, 18 and carries a cam 16 at each end which reciprocates spring-returned levers 13 connected by links 21 ... 23, Fig. 3, to a U-shaped frame 30 secured by releasable spring catches 31 to a slide 27 on which the moving mould half 28 is mounted. The part 23 has pins 34 which when moved to the left operate ejectors in the fixed mould half 29, and lugs 74 which, when moved to the right far enough to quite close the mould, open adjustable switches at 70 which permit a charge of molten metal to be delivered to the mould. If the mould cannot close springs 24 yield and the switches 70 remain closed. The molten metal is delivered by a spring-returned plunger 43, Fig. 7, moved down, from a position determined by an adjustable screw 54a, Fig. 1, by a lever 53 operated by a rod 55 moved up by a cam. If, however, either switch 70 is not opened, owing to the mould not being properly closed, current will pass to a solenoid 66, Fig. 7, and thus move a cranked lever 65 to hold open the inlet valve 61 of the pump and thus prevent delivery of metal. The machine also has a vertically reciprocated grid catcher 35, Fig. 1, which lowers each grid on to conveyer chains 40 which deposit it on locating pins of a guillotine of known construction, not shown, for removing surplus metal from the top and bottom thereof.
