Title: Improvements in and relating to a method of and devices for measuring the momentary values of varying accelerations
IPC: G01P15/08
Filed: 1927-11-24
Abstract: 285,420. Ambronn, R. Feb. 16, 1927, [Convention date] Vibrations, indicating, &c.-A method of and apparatus for investigating earthquakes and the propagation of artificially-produced seismic waves consists in measuring the pressure of a yieldingly suspended mass upon a pressuresensitive contact, the mass or the contact being carried by an adjustable lever balance. The variations of pressure due to vibrations or accelerations of the mass may be measured by electrical instruments measuring the variations of resistance between contacts of carbon, or piezo-electric crystals or by the optical double refraction of transparent plates. As shown in Fig. 2, the mass M is suspended from a spring F attached to one arm of a balance W, the other arm of which carries a counter-weight P. The mass carries a contact point which rests upon a fixed contact A, these contacts being in circuit with a source of supply or battery EK, Fig. 5, through a Wheatstone bridge arrangement comprising induction coils SF1, SF2, variable resistances Wi1, Wi2, and a measuring instrument Ga, the resistances being bridged by condensers C1, C2. By varying the resistances the bridge can be balanced for the direct current, so that the instrument will measure the alternating component of the pulsating current due to variations of resistance at the contacts A. Instead of attaching the mass to the arm of the balance it may be suspended from a fixed point, the contact A being carried on the balance arm. In another arrangement a compound lever balance may be provided, the mass carried by one of the levers being supported by a spring. For horizontal accelerations or vibrations the mass M may be supported as shown in Fig. 4, the pressure-sensitive contact being carried by a balance beam W provided with adjusting screws g.

Abstract: 320,248. Gill, H. A., (Rahe, S. E.). Oct. 22, 1928. Cutting-up.-Match splints are cut from veneer, paper, or other stock by drawing cuts in stages effected by successive blades 29, 30 under which the veneer 11 is pushed by a reciprocating plate 33 which picks up the veneer singly as they are fed along the table 20 by rollers 16, 17, which may be grooved to effect preliminary incisions in the veneers. The rear part of the plate is made with slits 34 to accommodate the blades, and the front recessed part with ribs 38 on which the veneer rests whilst being cut. At the end of the cut the plate 33 strikes a roller 53 and depresses a comb 47 which displaces half of the cut splints as shown in Fig. 10, and holds them whilst the continued advance of the plate inserts them into the carrier 12 or delivers them for packing. The rearward travel of the plate 33 effects the disengagement of the comb 47 by means of a roller 54. The cut splints may be separated into more than two layers by using a plate and comb as shown in Fig. 12.

[Also in Divisions F2 and H2] A terminal element for use in circular holes 26 of a printed circuit board 20, e.g. of epoxy resin, (not shown) comprises a tubular sheet-metal member having an arcuate end 6, and an oval end 4 having its major axis greater than twice the radius of arcuate end 6, the terminal element optionally including an open seam 8 and a finger-like retaining member 10 with an 'ear' formation 16. Each terminal when assembled in a hole in a printed circuit board is resiliently retained therein and is engaged by an external lead wire which is electrically connected to the terminal by, e.g. dip soldering. Insertion of the lead wire in the terminal opens out the formation 16 to abut an edge of the hole thereby preventing the terminal from moving in one direction during handling before soldering. A method of assembling such elements in the holes of a printed circuit board consists in using a template 22 (Fig. 5) having holes 28 corresponding to those in the printed circuit board, each hole 28 being filled with a terminal element from a plurality of them placed on the template, the entry of the terminals being effected by vibratory means. Terminals so lodged are transferred into holes 26 of the board 20 by the action of punching members 32 which are fixed underneath a plate 24 mounted in a machine (Figs. 13 and 17, not shown) which also includes other plates, guide posts extending into bushing supports through ball bearing retainers, aligning pins and components to hold warped printed circuit boards straight while the terminal elements are inserted through the template holes into the printed circuit board holes.

Abstract: 1312142 Semi-conductor bi-stable circuits REGIE NATIONALE DES USINES REXAULT 2 July 1970 [12 Aug 1969] 32134/70 Heading H3T The state of a memory such as a bi-stable M is remembered by a toroid T when the supply +HT fails, the toroid being set by an AND gate 6 responsive to the bi-stable output 8 and to the output 9 of a circuit 10 which detects when the supply fails, a temporary current flow after failure being maintained by, for example, capacitors C1, C2, and a further conductor 22 of the toroid being responsive to a circuit 23 detecting re-establishment of the supply to restore the bi-stable. When the supply fails, the input to diode 11 falls and the invertors 15, 16, 17 with their feedback capacitor 21 produce on line 9 a pulse, which with a bi-stable output of "1" on the line 8 sets the core T to "1". When the supply is reconnected and this is detected by the differentiator C24 R25 and the inverter 26 of the circuit 23, the core T is switched to the "0" state. If therefore it was not already storing "0" (as it would if M were "0" when failure occurred) then the core generates a pulse on line 4 to set M to "1", the bi-stable M having been rest to "0" when the power was restored. If the core stored a "0" then M would remain, as reset, at "0".

Abstract: 435,232. Prepayment mechanism for meters. METERS, Ltd., SIDES, H., and MAHER, D., Blackfriars House, Parsonage, Manchester. Nov. 9, 1934, No. 32264. [Class 27] Coin action, mechanical connection, thrust, and multiplecoin.-In prepayment meter mechanism in which two quantity wheels are selectively engaged by two toothed members according to whether one or other of two predetermined coins are inserted in the coin holder, the coin holder is provided with a spring-controlled slide a, Figs. 3 and 6, to which is pivoted a lever b carrying a pin k which extends through a slot m in a wall n of the coin pocket. A small coin inserted through a slot f rotates the lever b only, while a larger coin engages a ledge p on the slide and depresses this against the action of a spring, the slide being guided by a pin y engaging a vertical slot in the wall n. Two toothed levers d, e for engaging quantity wheels i, j, Fig. 1, respectively are pivoted at f, g on a frame plate h of the coin holder and are normally held out of engagement with the wheels by a spring r. When the lever b moves alone by the insertion of a small coin, the pin k enters a recess o in the slot m and actuates the lever d to engage this lever with the wheel i. If the slide a is moved the pin k cannot enter the recess o and the lever d remains stationary. When the larger coin of correct diameter is inserted, the pin k travels down the slot m and actuates the lever e. The mechanism may be set for actua- .tion by one size of coin only by moving a lever v to engage either a pin x on the lever d or the pin y on the slide a. In an alternative construction the lever b may operate one toothed lever and the slide a the other ; or the combined movements of the lever and slide may cause the lever to operate both toothed members.
Patent GB-324440-A (GB)
Abstract: 324,440. Marks, Sir G. C., (Finska Forcit-Dynamit Aktiebolaget). Nov. 10, 1928. Rolling-machines.-A plastic explosive is formed into strings adapted to be cut off to form cartridges, for example dynamite cartridges, by passing it between rollers which are provided around their surfaces with grooves having a form adapted to give the strings the desired cross-section. The plastic explosive is supplied to the board 1, Figs. 1 and 2, of the machine in a box built up of superposed interlocked frames 17, one of which is removed at a time to expose a layer 18 of the explosive. This layer is cut off from the rest by a wire or otherwise, and is passed between a pair of smooth rollers 2, 8, which reduce the layer to the desired thickness. The layer is then carried by a belt 5, and passed between grooved rollers 8, 9, which divide the layer into strings; and the strings are taken along by a belt 12 to another belt 15 for subsequent treatment, such as cutting into lengths and wrapping in paraffin paper. The machine is driven from a main shaft 20, Fig. 3, journalled in a casing 19. A pinion 21 on the shaft transmits rotation through a pinion 22, a shaft 23, and a worm gear 24, 25 to the spindle 26 of the lower smooth roller 3, and this roller is geared to the upper roller 2 by pinions 27, 28, Fig. 4. Another pinion 31 on the main shaft 20 transmits rotation through a pinion 32, a shaft 30, and worm gearing 33, 34, 35 to the spindles of the grooved rollers 8, 9. The shaft 30 also serves to'transmit movement to the belt 12, this being done through worm gear 38, 39 and the spindle 40 of the pulley 13 of the belt. The pinions 22, 32 can be connected to and disconnected from their respective shafts 23, 30 by friction clutches 62, 44 normally held in operation by springs 46', 46, but capable of being unclutched by bell crank levers 57<1>, 57 worked by cams 52, 53 on a spindle 51 provided with a hand wheel 50. The thickness of the laver of explosive as it emerges from the smooth rollers 2, 3 is controlled by adjusting the spacing between these rollers. For this purpose, the spindle 65 of the upper roller 2 is journalled eccentrically in bushes 66, which can be rotated by means of screw gearing 73, 72, Fig. 7, shaft 71, and screw gearing 70, 69 by a spindle 68 provided with a hand wheel 67. The upper grooved roller 9 is pressed down by springs, which yield if a solid object accidentally passes between the rollers. In order that the strings of explosive may have a circular shape, the grooves in the rollers 8, 9 must not be semicircular but of the shape shown in Fig. 8, that is, so that the openings 11 between the rollers are substantially squares with rounded corners. Specifications 1951/90; 17935/95, [Class 9, Ammunition &c.]; and 157,815 are referred to.
