Title: Improvements in or relating to supervisory circuit arrangements for axle-counting installations
IPC: B61L1/16
Filed: 1951-12-06
Abstract: 718,975. Counting-apparatus. SIEMENS & HAI:SK™,' AKT.-GES. Dec. 6, 1951 [Dec. 6, 1950], No. 28653/51. Class 106 (1). [Also in Group XXX] A supervisory circuit arrangement for axlecounting installations comprises a step-by-step switch for counting-in and a step-by-step switch for counting-out the contacts of a main contact bank of the step-by-step switch for counting-in being connected to corresponding contacts of a main contact bank of the step-by-step switch for counting-out at least ' one' of the stepby-step switches being provided with an auxiliary contact bank, the contacts of which are so connected to the contacts of the two main contact banks that there exist connections of a 1st, 2nd, 3rd, &c. contact of the step-by-step switch for counting-out to a 2nd, 3rd; 4th &c. contact of the step-by-step switch for counting-in, so that as soon as the step-by-step switch for counting-in leads the step-by-step switch for counting out by one step, a connection is established between the contact arms of the auxiliary contact banks, if each switch is provided with an auxiliary contact bank, or between the contact arm of the auxiliary contact bank and the contact arm of one of the main contact banks, which connection is included in the operating circuit of a relay. The counting- in step-by-step switch comprises a contact bank EZ and the counting-out step-by-step switch comprises two contact banks AZ1 and AZ11. The contact banks of the step-by-step switches are interconnected as shown. The circuit arrangement for a track counting point i comprises an impulse emitter contact 701, a supervizory relay A, a counting mechanism relay X, a restoring relay Y and a relay G which when energized indicates that the associated track section is clear. The relays A, X and G respectively are normally energized and the relay Y de-energized. In operation, when an axle enters the track section past the point i the contact 701 is opened and contact 702 is closed so that the relay A is de-energized to open contacts 101, 104 and close contacts 102, 103. Relay G is de-energized. The switch EZ steps-on to de-energize the relay X to open contacts 404, 405 and close contacts 402, 403. Where the switch EZ is next only one step ahead of the switch AZ the relay Y is energized to close contacts 501, 502, 503 and open contact 504. The relay Y remains energized while either contact 103, 403 is closed. When the switch EZ is next in agreement with the switch AZ and the contact 701 is closed the relay X is energized through the contact banks EZ, AZ1 and the contact 503 to close contacts 401. 405 and so energize relay A to close contact 104. Contacts 103, 403 are opened to de-energize relay Y and close contact 504 to again energize the relay G and indicate that the truck section is clear. The arrangement is such that should the counting mechanism and/or voltage fail the relay G remains de-energized.

IPC: B28B3/12
Filed: 1933-10-18
Abstract: 427,480. Moulding tiles &c. in endless-chain machines. McCONNEL, J. C. I., 10, Cambridge Place, Victoria Road, Kensington, London. Oct. 18, 1933, No. 28889. [Class 87 (ii)] Tiles, bricks, &c. are moulded by an apparatus in which cement is carried through an aperture by an intermittently moving conveyer to form a continuous moulded length which is afterwards cut up, the intermittent movement being such that the period of rest is shorter than the feed period. During moulding, pallets 38 constituting the conveyer travel along a frame 11. The intermittent feed mechanism comprises a belt pulley 20 which drives through gearing a crank 25. The crankpin 26 engages a block 27 which slides on a pivoted arm 28 connected at its lower end to a feeding member 31 carrying a pawl which engages the pallets on its forward movement. By means of the slide block 27 the arm 28 is moved slowly forwards and rapidly backwards. The pallets 38 are supplied to the feed mechanism by a continuously moving belt 13, provided with a gap 42, and are retained on the belt by a detent 60 which is released by the backward movement of the arm 28. The pallets slide on angle irons 35 which are held to the frame 11 by dogs 36 and pass under the wall 71 of the hopper 15 where they are charged with cement and sand. The wall 71 is hung so that it can lift if a misplaced pallet should enter the hopper. The cement is shaped on the pallet by a roller 73 which has a concave face and beveled flanges 76. A slipper 75 scrapes the roller 73 and compresses the cement on the pallets. A key-marking device comprising a spring-controlled plate 80 having a grid of marking blades on its underside is pressed on to the cement by a cam lever, and V-shaped blades 184 are also provided to indent the cement at the places whore it is subsequently cut. The pallets then pass through a second hopper 16, which supplies facing material, and under a roller 90, which is not provided. with a bevel 76 so that the edges of the tiles are coated with facing material. The cement strip is cut into tiles by knives 100 and nail holes are formed by punches 101 carried by a camoperated plate 17, two tiles being formed on each pallet. A box 18 with a perforated bottom supplies pigment to the surface of the tiles and is provided with a tapping device operated by the cam 124. All the various devices are driven in timed relationship from the pulley 20 through shafts and bevel gearing. According to the Provisional Specification the first roller 73 may have grooves or ridges to form the key marks.

Title: Process for the production of chlorocresols
IPC: C07C37/02
Filed: 1931-10-17
Abstract: Mixtures of (n + 1) chlorotoluenes with (n) chlorotoluenes (n being the number of chlorine atoms present in the nucleus) in which the former preponderate are converted to chlorocresols by heating in an autoclave with the quantity of alcoholic or aqueous-alcoholic alkali hydroxide required to convert (n + 1) chlorotoluene into (n) chlorcresol, the temperature being adjusted to convert the (n + 1) chlorotoluene alone.  Thus a mixture of trichlorocresol isomers can be prepared from crude tetrachlorotoluene which also contains trichlorotoluene and the separated trichlorotoluene can be used in the preparation of a further batch of tetrachlorotoluene or it can be converted into dichlorocresol.  In examples (1) crude tetrachlorotoluene containing trichlorotoluene is heated to 170 DEG C. in an autoclave with methanol and caustic soda lye.  Unchanged trichlorotoluene separates on distilling off the methanol and trichlorocresol separates on acidification of the liquor.  (2) Crude pentachlorotoluene containing tetrachlorotoluene is heated in an autoclave to 130-140 DEG  C. with methanol and potassium hydroxide. After distilling off the methanol the liquor is diluted with water and acidified to obtain 2 : 3 : 5 : 6-tetrachlorocresol. Di- and monochlorocresol can be similarly produced from tri- and di-chlorotoluenes containing di- and mono-chlorotoluene respectively, using temperatures of 180-190 DEG  C. and 200-210 DEG  C. respectively.

Title: Improvements in platen rotating mechanism for typewriters
IPC: B41J11/36
Filed: 1932-10-18
Abstract: 409,003. Typewriters. EUROPA SCHREIBMASCHINEN AKT.-GES., and BECK, F., 13, Mainzerhofplatz, Erfurt, Germany. Oct. 18, 1932, No. 29170. [Class 100 (iv).] Platen rotation for tabulating ; sheetfeeding arrangements.-In a mechanism for adjusting the rotation of the platen of a typewriter to predetermined positions independently of the ordinary line-spacing mechanism in which adjustable stops are provided on a rotating body which works in co-operation with the platen and can be caused to rotate together with the platen by an adjusting-lever, and in which three stops coact with a fixed stop on the carriage, the stops are arranged in a single circular row on the rotatable body and can be brought into operation by a setting-key. A disc 5, Figs. 2 and 3, is fast to a shaft 11 in the platen carriage and carries sliding stops 7 arranged in an annular series of slots 6 around its edge. Sufficient stops are provided to correspond with every line-space position on the longest sheet dealt with. Notches 9 on the stops are engaged by a spring 10 in active or inactive positions, and the stops are retained in the slots by a ring 8. The shaft 11 also carries a gear 12 and ratchet-wheel 13, and is rotated by a tabulator-lever 20 which operates a pawl 19 engaging the wheel 13. A fixed stop 25 in the form of a two-armed lever is pivoted at 26 to a holder 28, which is itself pivoted to the casing at 29, Fig. 6<a>. The holder 28 can be rocked into two positions against stops 30, 30<a>. In the position shown a downward nose 25<a> on the lever abuts on one of the stops 7, and by depressing the lever at 32, the stop is pushed into the active position. Then if the disc 5 is rotated by the lever 20 the stop 7 will meet the portion 25b of the lever 25 and the platen will be arrested, the holder 28 being rocked into the alternative position. On the return stroke of the lever 20, a nose 20 thereon engages the nose 25b on the lever and lifts it over the stop 7 when a spring 31 moves the holder back into the position shown in Fig. 6<a>, thus permitting rotation of the platen to the next stop position by actuation of the lever 20. A releasing disc 34 is mounted on a bush 35 sliding on the axle 11, and, when drawn forward by the action of a lever 42, presses all the active stops 7 back into the inactive position. The gear 12 meshes with a gear 15 which is mounted on a pivoted yoke 44 so that it can be swung either to drive the platen through a gear-train (not shown), or to drive an auxiliary feed-roller 47 through a gear 45. In this case the collating sheet lying around the platen may be fed only by the normal line-spacing mechanism, and only the separate superposed sheets passing round the roller 47 are advanced by the lever 20. The yoke 44 is held in either position by a spring detent co-operating with notches in the casing. The mechanism may be constructed with the functions of the fixed and rotatable parts interchanged. Specification 408,262 is referred to.
