Apparatus for separating and counting a jumble of loose fabric pieces P comprises a pair of deflectors 7 serving as a shoot into which the pieces P are fed. Under the deflectors 7 is a pair of kicker elements each comprising a rotor 8 with flexible fingers 9 which help to unscramble the jumble and toss pieces P on to a first endless belt conveyer 3 either directly or via a backstop 10. A sequence of conveyers 4, 5, 6 with kicker elements 16, 18, 20 and backstops 14, 24, 26, 28, 30, 32 follows, each conveyer travelling faster than the preceding conveyer as does the periphery of each kicker element. The repeated free falls and abrupt changes of direction separates the pieces P so that individual items are carried past a counting device 34 and delivered to a bin 36 by the last conveyer 6. Fig. 2 shows a modification wherein the pieces P are fed from a hopper with a housing 40 on to the conveyer 3. The pieces P drop through an opening 42 into a V formed by opposed angularly arranged belts 44, 46 associated with rotor-kickers 48, 50 the belts and kickers being driven as indicated by arrows. Kicker 48 rotates at such a rate that no pieces fall under the belt 44 (which is driven faster than the belt 46) but all will be directed to the centre of the hopper where belt 46 can pick them up. The kicker 50 pulls or knocks the pieces off the belt 46 and throws them on to a slide 52 leading to the belt 3.

Abstract: 1,037,976. Read-only memories; checking attendances. ELECTRIC & MUSICAL INDUSTRIES Ltd. May 2, 1963 [May 2, 1962], No. 16930/62. Headings G4A and G4T. The work location of a workman (e.g. a miner) is indicated by plugging a name board (not shown) into a known type of read-only memory so that magnetizable slugs 24, 25 ... carried by the board make inductive connections between drive and sense lines 3 to 5 and 6 to 11 respectively, the connections being such that, when the drive line into which the board is plugged is energized, a coded representation of the workman's name and other relevant data is transmitted on lines 18 to 23. The data includes a parity bit and this parity is checked before the data is serially punched on to paper tape. The read-only memory forms an indicator board representing one work location and several such memories are serially scanned. To cut down such scanning time a location full board is plugged after the last workman's name on each indicator board, causing the scanner to jump to the next memory. To prevent crosstalk between drive and read lines (Fig. 3, not shown) the read lines 11 are printed on opposite sides of an insulating sheet and cross as shown.

Abstract: 380,475. Galvanic batteries; reciprocating-punch machines. BUMKE GES., H. A., 8, Chausseestrasse, and AUTOM-SPEZIAL-MASCHINEN GES., 5, B³lowstrasse, both in Berlin. June 11, 1931, No. 17046. Convention date, July 15, 1930. [Class 53.] Machines for making dry batteries.-In a machine for applying covers to dry batteries a number of devices are provided for centring the carbon dollies, cutting out and. punching holes in the covers and for placing and pressing the covers in position. The various devices operate in a horizontal position, and the batteries are moved through the machine in a straight line by means of a conveyer. In Fig. 1 the conveyer is shown at IV and the batteries are first brought to the centring device I which consists of a stamp 2 having at its end a large and small hole which fit over the battery container and the projecting carbon rod respectively. An oppositely disposed stamp 4 is given a reciprocating movement by means of a cam 6. The battery is thus pushed forward by the stamp 4 and is pressed against the stationary stamp 2 which centres the dolly. On the withdrawal of the stamp 4 a pin 8 passing down the centre of the stamp 2 and operated by a cam 9 moves forward and pushes the battery back into its position on the conveyer. The battery is then conveyed to the device II where a cover with a central hole is placed over the top of the battery. The covers are stamped out of a strip of material and provided with central holes by the device shown in Fig. 2 which is a section of the machine through the device II shown in Fig. 1. The strip of material is shown at 11 and it is given a stepby-step motion in front of a punch 15 which carries two cutting devices or punches 23, 22 corresponding in diameter, to the carbon rod and the cover respectively. An eccentric 21 reciprocates the punch 15 which cuts out a cover by the punch 22, this cover having a central hole produced by the punch 23 during the previous step of the strip 11. The punchedout cover is placed over the carbon rod of a battery by an axial movement of the latter by a stamp 26. The battery with its loose.cover is then carried to the device III which is constructed similarly to the device I but has in addition an abutment 28 which moves into the zinc container of the battery and presses the cover down upon the electrolyte. The stepby-step motion given to the strip 11 is produced by an eccentric 12 and levers 13 and a member 14 which presses against the strip. When the member 14 moves downwards it takes the strip 11 with it. Reverse movement of the strip is prevented by a weighted lever 16. The conveyer consists of a track 34 having recesses for the battery cells. It is moved forward and raised simultaneously by means of rotating segments 35 as shown in Fig. 4.

Title: Improvements in telephone receivers
IPC: H04R13/02
Filed: 1925-07-08
Abstract: 248,245. Western Electric Co., Ltd., (Bell Telephone Laboratories, Inc.). July 8, 1925. Telephones; diaphragms.-The diaphragm of a telephone receiver is heat treated to develop its maximum permeability at low magnetizing forces. Preferably, an alloy of nickel and iron is used, for example that described in Specification 188,688, [Class 82 (i), Metals. Extracting &c.], the finished diaphragms being heated to 1100‹ C. The diaphragms can thus be made of low mass for use on long subscriber loops where the magnetizing current and the flux densities in the diaphragm and pole pieces are low. In the receiver shown in Fig. 1, the diaphragm 10 and pole pieces 7 are produced as before stated, the winding 5 being on the centre leg of the E- shaped pole piece, the latter being welded to a mounting plate 8. In a modification, an additional perforated plate, produced as before stated, is mounted adjacent the diaphragm and serves as a magnetic shunt which becomes effective at higher magnetizing forces and minimizes acoustic shocks in the receiver. The diaphragm, on account of its low mass and high permeability, is particularly suitable for the receiver of a deaf set. illustrated in Fig. 9. The cap 30 of the receiver is embedded in an earpiece 25 moulded to the shape of the meatus of the ear and provided with a sound canal 35 which registers with the sound passage 21 of the cap 30.
