Patent GB-339338-A (GB)
Title: Improvements in or relating to counting devices
IPC: G06M1/08
Filed: 1929-09-03
Abstract: 339,338. Norballe, H. J. Sept. 3, 1929. Counters for checks, coins, tokens, &c. - The operations of a plurality of counting mechanisms are registered on a single counter by the operation of a token or ball release device comprising a storage receptacle with a plurality of outlets therefrom each controlled by an appropriate counter for delivering a ball to a common chamber and provided with means for agitating and guiding the tokens to the outlets. As shown in Figs. 1 and 2, an electromagnet 10, associated with each counter, is operated on the actuation of the counter and through its spring- controlled armature 11 operates an apertured slide 7 so as to effect the delivery of a ball 1 from a storage-chamber 2 through an apertured plate 12 and tube 12a to a V-shaped run-way 13 common to all the counters. The storagechamber 2 is formed as a long and narrow vessel with a bottom plate 3 having holes 4 corresponding in number to the number of counters and slightly larger in diameter than the balls. Jamming of the balls in the chamber is prevented by agitating a bar 5 with slots 6 registering at times with the holes 4. The balls pass from the run-way 13 to an outlet 14 at which position a spring-controlled lever 17 permits one ball at a time to be delivered to a rotatable star wheel 16 whereby the balls are forced into a tube 15 and conveyed by a flexible tubular member 24 made of spiral spring wire back to the storage-chamber. During the feeding of the balls, the balls operate a bell-crank lever 19 which by mechanical or electrical means effects the actuation of a totals counting-mechanism. Return of the balls is prevented by a spring 38 acting on the bell-crank 19 or by means of a spring-controlled ball 39 extending into the tube. The rotation of the wheel 16 is effected through reduction gearing 26 - - 28 from a motor 25. A pinion 29 in gear with the wheel 28 operates an eccentric 30 and link 31 to effect the oscillation of a lever 32. The lever 32 carries a pawl 33 which drives a toothed wheel 34 provided with an eccentrically mounted pin 36 coupled by a connecting rod 37 to the agitating bar 5.

Abstract: 379,535. Levelling-devices for weighing and other apparatus. BENJAMIN, H. S., 1005, Parkway R., Utica, New York, U.S.A. Sept. 29, 1931, No. 27093. [Class 143.] A levelling device for a weighing or other apparatus mounted on a wheeled base 1 comprises auxiliary supporting members (the legs 8 for example) adapted to be brought into contact with the floor in order to lift certain of the wheels therefrom and rigidly support the base, the auxiliary members being adjustable for levelling purposes and being movable into active position by means including an operating lever 15 situated within a hollow column 2 carried by the base. The legs 8 are carried by a sleeve 7 rotatable about the front axle 4 and each terminate in a screw 9 having a head 10 to bear upon the floor. Upon the movement of the operating lever 15 into the position shown in broken lines, a pitman 12 connected thereto rotates the sleeve 7 and moves the legs into active position. At the same time, a projection 22 on the slotted rear end of the pitman engages and locks a toothed wheel 23 rigid with the rear axle to prevent rotation of the wheels that remain in contact with the floor. The operating lever is maintained in its alternative positions by lugs on a bar 19.

Title: Improvements in or relating to pressed chip bodies
IPC: B27N3/06
Filed: 1966-06-17
Abstract: To the pressed chip bodies of the parent Specification, a layer of absorbent material adaptable to the contours of the moulding is applied to the still liquid thermosetting plastic or mixture.  The parent Specification describes applying a liquid thermosetting plastic to a pre-pressed moulding of fibrous material and binder, and pressing under heat, the binder containing a substance, e.g. ammonia or ammonium chloride, which causes a partial condensation of the thermosetting plastic when this is applied, thus forming a barrier layer preventing penetration of the thermosetting plastic into the pores of the pre-pressed body.  The absorbent material may be tissue-paper or woven textile fabric, and may be coloured. A thermosetting plastic mixture exemplified comprises an OH-group-containing polyester resin.

Apparatus for forming arcuate flanged bearings comprises: a first roller 31 for receiving a longitudinally flanged metal strip 15, the roller having a knurled area 32 and a lip member 35 under which the strip end is positioned, a second roller 30 which engages the outer edges of the strip flanges and at least partly surrounds them, the knurled area gripping the base portion of the strip and feeding the strip between the rollers, and the rollers reducing the flange height uniformly throughout the length of the strip. The strip 15, which is substantially equal in length to the arcuate length of the finished bearing, comprises a steel backing on which is east, clad or sintered bearing material. The necessary oil holes and oil grooves are formed before the strip is bent. A pusher mechanism 33 feeds the strip 15 to the rolls 30, 31 and exerts pressure on the strip to help feed it through the rolls. Back-up rolls 40 maintain the strip in contact with the roll 31 and the roll 30 is retractable to the position shown dotted to receive the strip prior to rolling. During rolling, the strip flanges extend into grooves (41) in the roller 30, Fig. 5 (not shown). A stripper device 50 engages the formed strip 15 and forces it out from underneath the member 35 allowing it to drop out of the roll forming machine after which the rollers reverse back to their original positions. The completed bearing is machined to remove any knurl marks from the bearing surface.
