Abstract: 872,980. Spring balances. WALSALL SPRING & PRESSWORK CO. Ltd. Jan. 14, 1960 [Jan. 17, 1959], No. 1807/59. Class 143 A spring balance is suspendable by a looped member 11 having a limb 111 which passes through the casing 10 and to which are anchored a plurality of weighing springs 13. A guide member 12, whose displacement relative to the casing indicates the load on the springs, supports both the load-bearing hook 14 and an anchorage member 141 for the lower ends of the springs. As shown, the anchorage member is integral with the hook and passes through an open ended slot 106 in the casing and through a hole in the guide member. The guide member is visible through a slot in the front of the casing (not shown) and carries an index 121 co-operating with a scale engraved on the casing: alternatively the scale may be on the guide member and the index on the casing in which case the slot through which the scale is viewed may be covered by a lens. When not in use, the suspension loop and load hook are foldable about the casing. In alternative arrangements (not shown) of the load hook attachment the hook is attached to an extension of the guide member below the lower closure plate 105 and the anchorage member is not integral with the hook but comprises a separate member within the casing attached either to the guide member or to the plate 105. The Provisional Specification states that the casing may be leather covered.

Title: Improvements in or relating to telephone exchange systems
IPC: H04M3/64
Filed: 1932-01-21
Abstract: 389,613. Manual exchange systems. ERICSSON TELEPHONES, Ltd., 67, Kingsway, London, WILMAN, C. W. and TRAPP, C. C., Ericsson Telephone Works, Beeston, Nottingham. Jan. 21, 1932, No. 1861. [Class 40 (iv).] An exchange adapted to be worked by a blind operator is characterized by the feature that whenever a line requires attention, a buzzer is sounded and the number of the line is exhibited on a panel in a tangible manner, e.g. in Braille characters. A high-note buzzer indicates a calling condition, while a low-note buzzer indicates a clearing condition. Construction of indicator, Figs. 1 and 2. For each digit to be indicated there are provided four pins 19 adapted to be projected from the panel 11 to form Braille characters by magnets 14. Fig. 3 shows the connections for operating the magnets controlling one set of pins in various combinations by the application of potential to a single wire. A rotary switch DM, Fig. 6, takes up a position characteristic of the line and controls the appropriate magnets for the tens and units digits over separate banks. As an alternative, the switch or a pair of switches may rotate drums bearing the characters into the appropriate position under an aperture in the panel. Operation. When a subscriber calls, the common line relay SA energizes, and closes a circuit for stepping the switch DM into engagement with the line, whereupon relay H energizes, connecting up the high-note buzzer HB and completing circuits for indicating the number of the line. The operator plugs into the calling line, and line relay A energizes ; relay H falls back and removes the number from the panel. On plugging into the wanted line, common sleeve relay SC energizes and the switch DM steps into engagement with this line, whereupon relay H energizes, connecting up the lownote buzzer LB and closing circuits for the indicator. The operator can thus check the number before ringing. Relay D energizes upon reply and disconnects relays SC, H. Release by either party causes the operation. of the corresponding sleeve relay SB or SC, whereupon the low-note buzzer LB gives the clearing signal and the number of the line is indicated. It will be seen that, since relay SB disconnects relays SA, SC and relay SA disconnects relay SC, clearing signals from calling lines have first preference, then calling signals and lastly clearing and checking signals from called lines. A modification using individual' line relays is described.

Filed: 1923-01-23
Abstract: 208,040. Kruse, F. Jan. 23, 1923. Addition to 178,444. Sausages and the like.-In a sausage-twisting machine of the type described in the parent Specification, portions of a number of casings are placed between transversely aligned belts which are operated to twist the sausages, and a vertically movable conveyer-frame is provided which carries the twisted lengths to a receiving-table and positions the adjacent untwisted lengths between the belts. The belts 23 are trained around driving-pulleys 21 and idler rollers 22 which are carried on frames 25 pivoted on brackets 24. The casings 100 are introduced between the belts 23 when they are positioned as in Fig. 5, rotation of the belts horizontally positioning the frames 25 against stops 95, Fig. 6. After twisting, a slight backward movement of the belts returns the frames 25 to the vertical position and allows the conveying-frame to disengage the casings. The formers 20, 30, situated between adjacent pairs of belts, are slidably mounted on longitudinal bars and are operated in opposite directions by levers 31, 32, 33, 35, 36, 37. The formers 30 are slightly offset to permit of alignment with the formers 29. The conveying-frame comprises members 40 in which are journaled shafts 42, 43 carrying sprockets 46 connected by chains 49 carrying cross-bars 50 which are positioned between, pairs of belts when the frame is lowered. Grooved rollers 44, mounted on the shafts 42, 43, are longitudinally notched to receive the cross-bars 50 and support the casings in their transit. The conveyer is operated by a hand-wheel 53 provided with a notch and pawl positioning-device. A roller-ended smoke-stick is positioned under the sausages after twisting and is moved by the conveyer to inclined run-ways 97 and from thence to the receiving-table. The conveyer-frame is lifted by stops 60, on pivoted handlevers 59, which engage the underside of the frame. The belts may be operated through pinion gearing by a hand-wheel, or a power-driven shaft may be clutched to the mechanism, the clutch comprising a wheel continuously rotating on a shaft and having a pin which contacts with an opposing, spring-pressed pin on a disc keyed to the shaft. The clutch is disengaged by a knifeedged lever engaging a shoulder on the spring- pressed pin and forcing it out of engagement against the action of the spring. The formers are connected to the clutch-lever. A hand-wheel, provided with a shrouded pawl, is used for imparting the slight backward movement to the belts.

Title: Improvements in brakes for hand trucks
IPC: B62B5/04
Filed: 1925-01-23
Abstract: 241,066. Lafferty, J. H., Stockton, G., and Stockton, E. F. Jan. 23, 1925. Blocks and shoes; force-transmitting mechanism; locking by frictional detents.-A brake for hand trucks, particularly of the sack track type, comprises brake blocks which are applied to or released from the wheels by springs under the control of a hand lever disposed adjacent one of the track handles. As shown, brake blocks E disposed one on each side of the truck are each suspended by bolts F from the flange C of an angle plate secured to the side member of the truck and are normally held raised from the wheel B by springs G. The blocks are applied to the wheels by turning a transverse shaft H connected by a crank J and a link K with a hand-lever M and provided with flattened ends H<1> which act as cams engaging the upper surface of the blocks E. The mounting of the blocks is such as to permit them to rock to a limited extent for adjustment to wheels which are not quite true. The springs G may instead be disposed on the upper parts of the bolts F so as to tend to apply the blocks to the wheels, the cam ends H<1> of the shaft H being in this case arranged beneath plates D on the upper parts of the blocks. The link K may be disposed within one of the longitudinal members of the truck.

Title: Improvements in telephone or like systems
IPC: H04Q1/32
Filed: 1940-02-05
Abstract: 534,358. Automatic exchange systems. AUTOMATIC TELEPHONE & ELECTRIC CO., Ltd., McCLEW, J. W., and RICHARDS, I. T. Feb. 5, 1940, No. 2187. [Class 40 (iv)] In a system in which the connections of an impulse-responding relay which repeats impulses over a two-wire junction are reversed for signalling purposes, a temporary circuit is made for preventing the release of the relay during such reversal. In an auto/auto repeater, Fig. 1 (not shown), a third winding on the line relay, which may also be used for applying tone signals to the line, is connected up by the D relay on the response of the called subscriber and disconnected by a sluggish relay which is disconnected when D pulls up. When the called party hangs up, the circuit is made again by the relapse of the D relay and is broken by the re-operation of the sluggish relay. In an R.C.X. of the kind described in Specification 503,099 the impulse relay A pulls up when the operator plugs in followed by B, FG, and if the calling party is still on the line, DD and finally DDR which reverses the connections of A and indicates the release of FG, DD however remaining locked. A temporary holding circuit is thus made over the middle winding of A which may be used additionally for applying tone signals to the line. If the calling party is not on the line the reversal will not take place until the calling party replies to a ringing signal from the operator and DD, DDR then operate as before. The reply signal from the called party exercises a similar control. A temporary circuit for A is made also when the calling party manipulates the switch-hook to attract the operator. Relay FI falls when the hook is depressed, releasing DD, which makes the temporary circuit DDR, and FG is re-operated and opens the temporary circuit. The reverse operation when the hook is released causes a further temporary circuit to be made so that A cannot follow the hook impulses.

Abstract: 576,042. Generating combustion products under pressure. HALLOWELL, E. Feb. 8, 1944, No. 2323. [Class 51 (i)] [Also in Group XXVI] Gases generated in an oscillating column gas generator such as described in Specification 574,554, or other suitable I.C. engine, are led into a diverging duct 47 of about the same acoustic period as the duct 41 and thence to an impulse turbine 40. Compressed-air from a compressor 18 driven by the turbine 40 is heated in an economizer 12 and passed to a chamber 21 surrounding the ducts 41, 47. Here it is further heated and passes out to the rear of the turbine 40. The heated air passes through the turbine in the reverse direction during the low-pressure part of the acoustic cycle and mixes with the combustion products. The exhaust of the turbine 40 passes to a pressure-equalising chamber 10 and thence to a turbine 11 which exhausts to the economizer 12. The turbine drives a low-pressure compressor 14, in series with the compressor 18, and an electric generator 15. A cooler 17 is placed between the compressors 14, 18. The gas generator is supplied with compressed air through pipe 52. In starting, highly explosive fuel is supplied by a carburettor 25. When the air pressure rises, it acts upon a.piston 33 to open a valve 31 through which normal fuel is supplied. The valve 22 is closed during starting. Specification 574,552, [Group XXVI], is referred to in the Provisional Specification.

Filed: 1940-02-10
Abstract: 537,550. Roofing. BROWNJOHN, H. S. Feb. 10, 1940, No. 2588. [Class 20 (iv)] A method of covering a roof with slates or tiles consists in using slates of various lengths but of equal width. The length of each slate is an integral multiple of the length of the shortest slate used, the length of which is twice the overlap between adjacent slates. Thus if the lap is three inches, the lengths of the slates would be 6, 12, 18, 24 inches, and so on according to the number of sizes used. The width of the slates may be 12 inches so that standard sizes may be used. The drawing shows the method of laying slates - or tiles of four different sizes. The first course consists of slates A, each 24 inches long; laid lengthwise and butt jointed, the joints being covered by slates B each 6 inches long. For the second course, a slate C, 18 inches long. is placed over a slate A with a part of each vertical edge butting against a slate B. A slate D, 12 inches long, is then placed centrally over the space between each slate D. In the third and fourth courses, the procedure for the second and first courses, respectively, is reversed. The slates may be secured to wooden battens H by nails G, the tails being held down by wire clips F. Metal clips E may be used to secure the slates to metal laths K.
