Title: Improvements in wrapping machines
IPC: B65B11/56
Filed: 1935-04-03
Abstract: 456,334. Wrapping-machines. DEHN, F. B., 103, Kingsway, London.-(Procter & Gamble Co. ; Gwynne Building, 6th Street, Cincinnati, Ohio, U.S.A.) April 3, 1935, No. 10378. [Class 94 (i)] A machine for wrapping cylindrical containers by rolling them in contact with a wrapper comprises means for supporting the containers individually during rotation in an upright position as they pass through the machine, means being provided for regulating the feed of containers. The containers are rolled by an endless belt so as to pass wrappers in a magazine and are initially supported on rails which are replaced as the wrappers are applied by cam-operated stools engaging the bottoms of the containers and carried by an endless chain, the containers passing between fixed upper and lower folding blades and finally under a soft roller which presses the folds. The containers are released by an escape mechanism rendered inoperative by the absence of a supply. The containers are fed to the machine by a belt 26, Fig. 2, into engagement with an endless band 112 supported on its operative run by spring-influenced pulleys 149. The band rolls the containers past a glue-applying device 155 into contact with the outermost wrapper in a magazine 187 where the containers are supported by stools 178, thence to the folders 202 and then under the soft roller 220. The timing mechanism comprises a notched disc 151, Fig. 9, driven by a ratchet 124 operated by a reciprocating member 129 actuated in turn by trip mechanism from a constantly rotating shaft 116. The trip mechanism, comprising a pivoted catch 136 engaging a projection on the member 129, is controlled by a spring-influenced rod 140 connected to a bell-crank 143 one arm of which lies in the path of the containers ; if a supply is absent the rod 140 raises links 138 connected thereto, the links carrying a bar engaged by a projection 137 on the catch 136 to render it inoperative. The glueing device comprises an electrically heated vessel 34, Fig. 4, into which a disc 44, driven by a belt 158, dips. Rotating in contact with the disc 44 are discs 54, driven by chain-and-bevel gear 52, 48, which apply stripes of glue to the container ; scrapers are provided for removing excess of glue from the discs. The wrappers are contained in a magazine fitted with a weight-actuated follower and the tail end of the outermost wrapper is glued by a travelling belt 95, Fig. 8, a rod 97, near the belt curling the end of the wrapper as it is withdrawn.

Title: Improvements in casting machines
IPC: B41B5/06
Filed: 1951-05-04
Abstract: 715,887. Discharging molten metal. HUMPHRIES, J. M. May 1, 1952 [May 4, 1951], No. 10471/51. Class 51 (2). -[Also in Groups XVI and XXII] A type-casting machine comprises a pivoted base plate for a mould, a melting pot for the casting material, a cylinder in the melting pot having an inlet for drawing casting material therefrom, a piston in the cylinder, and a tube communicating through the piston with the interior of the cylinder having a top end adapted to register with an aperture in the base plate or a member associated with the base plate under the mould when the base p!ate is substantially horizontal, the piston being adapted to be depressed through downward movement of the pivoted base plate. The mould is supported on a base plate 1 pivoted on a rod 5 and a shear plate 3 is slidable laterally in a groove therein to cut off excess metal. A cylinder 12 in the metal pot 14 has a metal valve inlet 13 through which metal is drawn when a piston 11 moves upwards. The piston is secured to a hollow tube 10 with a nozzle 9 to deliver metal to the mould. When the piston descends metal is forced out through the valve 13 until this is closed, when the rest of the metal is injected into the mould. The piston is raised by a tube 16 actuated by an arm 19, and is lowered by pressure of the base plate on the nozzle 9, the metal inlet opening in the base p!ate being flared for this purpose. In operation, an original is placed in the mould and metal poured in on top to form a matrix. The base plate is then raised and inverted to empty the mould, and re-inverted. The matrix is then positioned in the mou'd, spaced from the bottom thereof. As the base plate is raised, a cam follower 7 attached to the shear plate 3 co-operates with a cam groove in a cam member 8 integral with the arm 19; so as to slide the shear plate in its operative action and also to slide the member 8 along the pivot rod 5, whereby a groove 20 in the arm 19 engages over a wedge member 21 to lock the piston in its upper position. The movement of the arm 19 and the piston' stroke is limited by a detent 22 movable in a slot in the wedge member, and can be altered by placing an adjustable stop in the slot. The base plate is then pressed down on the nozzle 9, thereby releasing the arm 19 and depressing the piston, to inject metal under the matrix and cast a reproduction. On raising the plate 1 to remove the matrix and reproduction, the p'ate 3 slides to remove surplus metal. The metal pot 14 is rectangular and has two tubes 15 to receive cartridge-type electric heating elements, or a gas burner or other heater may be attached to a bolt 15a.

Activating impurities are removed with the sulphur. An additional catalyst may be used, such as sulphates, sulphites, chlorides of the heavy and light metals and of ammonium, such as iron chlorides, manganese sulphate, sodium sulphate, also bases and acids such as caustic soda and sulphuric acid, or a catalyst of an organic character such as paraformaldehyde. The material extracted may contain sulphur and the desired catalyst, both being removed by a suitable extractant.
Patent GB-834963-A (GB)
Title: Improvements in or relating to electromagnetically controlled reversers for electricmotors
IPC: H01H50/32
Filed: 1958-04-01
Abstract: 834,963. Control of D.C. motors; electricallyreleased switches. TELEMECANIQUE ELECTRIQUE. April 1, 1958 [April 5, 1957], No. 10500/58. Classes 38 (3) and 38 (5). Electric motors M1, M2 are operated in a forward direction by moving controller handle A to close contacts IAV1, IAV2, and open contacts IAB1, IAR2, a reverse contactor CAR being kept closed at this time by means of a permanent magnet so that current flows through contact IAV1, coil CAV, resistor R, coil CAR and contact IAV2. This current flowing through the coil CAR is sufficient to de-magnetize the contactor whereby contacts CAR2 are closed and a heavy current passes through the coil CAV to energize the forward contactor. Contacts CAV1, CAV2 are then opened so that a reduced current maintains the energization of the forward contactor. Closure of contacts CAV3 operates contactor CL for closing line contacts L, and, since contacts AV1, AV2 are closed, the motors start in the forward direction. A rectifier D prevents discharge current from other contactor-coils from opposing the holding current of the contactor CAV, whereby the latter is not released when the other contactors are operated. The reverse operation is similar to that described. If, during forward running operation, a break occurs in the winding of the contactor CAV, the contactor nevertheless remains operated owing to the provision of a permanent magnet. An attempt to start in reverse under these conditions is unsuccessful because contactor CAR cannot close, and, since contacts IAR2, CAV3 are closed, the contactor CL cannot engage. The contactors CAV, CAR have shafts TAV, TAR, to which are fixed the various contacts of the contaetors, these shafts being mounted in bearings G screwed to bars H. These bars are connected by crosspieces I which form elements of the magnetic circuits of the contactors. The magnetic cores are fixed to the cross-pieces and comprise two parts N1, N2, which have low and high retentivity, respectively. The shafts TAV, TAR have a connecting-rod M to prevent simultaneous closure of the contactors.

Patent GB-105418-A (GB)
IPC: F02N15/02
Abstract: 105,418. Ritson, C. April 19, 1916. Turning-gear.-Danger to the operator is prevented by the use of pairs of pawls on the parts connected to the handle, sprocket-wheel, &c., one engaging a fixed ratchet-wheel, and the other engaging a ratchet-wheel on the engine shaft and being swung aside on reversal of the engine. A flange on a hollow shaft turned by the hand-lever is secured by bolts 18 to a pair of inner rings 13, on which turn loosely a pair of outer rings 11 carrying lugs engaged, with lost motion, by projectors on the driving-flange. Pawls 15, 14, engaging respectively an outer stationary ratchetring 5 and a ratchet-wheel 3 on the engine shaft 1 or an extension thereof, are pivoted on the rings 11 and kept in position by springs 24, 25. The bolts 18 pass through slots 19 in the pawls, so that during starting, the pawls 14 remain radial and drive the ratchet-wheel 3. Overrunning, when the engine starts, is allowed by lifting the pawls 14. Back-firing causes the rings 11 to be stopped by the action of the pawls 15, the pawls 14 and ring 13 being rotated until the pawls disengage from the wheel 3.

Abstract: 1,063,775. Photographic cameras; exposure control systems. EASTMAN KODAK CO. March 13, 1964 [March 18, 1963 (2)], No.10640/64. Addition to 970, 289. Heading G2A. A camera has a photo-electric exposure control system including a galvanometer 11 whose moving element 13 is deflectable in a first direction as a function of the scene light intensity illuminating the photo-electric element 10, and a switch 12 for coupling the galvanometer for voltage testing purposes to a battery 18 which gives a deflection in an opposite second direction against an opposing spring. Resistor 19 represents the load at camera drive motor 20 which is connected to the battery by trigger switch 21, and resistors 22, 23 are used to adjust the galvanometer deflection. Member 13 has an aperture diaphragm vane 29 at one end and, at the other end, a scale 25 provided with exposure indicia 27 and battery potential indicia 28 corresponding to deflection in the two opposite directions against a fixed mark. Scale 25 projects into the axis 32 at the viewfinder. Alternatively, the scale may be fixed while the meter 11 has a moving pointer with a snap-action spring-loading giving a sudden increase in deflection if the battery potential enters the "GOOD" range. A magnetic spring arm is used for this purpose. In a modification, the battery is tested without disconnecting the photo-electric element whose small output is negligible by comparison with that of the battery and is over-ridden. The opposite deflection during battery testing is made against resisting spring means which may be helical, spiral, a cantilever, thereby decreasing the galvanometer sensitivity.

Abstract: 1533778 Head adjustment in magnetic disc data systems BASF AG 17 March 1976 [2 Dec 1975] 10651/76 Heading G5R For use in adjusting the position of a magnetic head (13), Fig. 1 (not shown), when setting up a magnetic disc data system, a magnetic test disc has at least one test track (14) recorded with groups of first test signals, such as 4 to 9, Fig. 2, with intervening second test signals, such as 1 to 3, which have different amplitudes to those of the first signals, the first signals extending alternately on one side and then the other of the centre line 18 of the test track. The disc may be flexible and rotated at 360 r.p.m. The second signals are symmetrical relative to the centre line 18 and are arranged so that the test track has groups I, II &c. of test signals, each group having three of the second signals 1, 2, 3 and six of the first signals 4 to 9, there being from 4 to 36 such groups, preferably 6 or 12, in each test track. If the data system uses recording frequencies f and 2f, e.g. 250 KHz and 500 KHz, each of the signals 2 and 4 to 9 is recorded at f and each of the signals 1 and 3 at 2f. If the disc is running true with the head (13) accurately on the centreline 18, the test signals between lines 20 and 21 in Fig. 2 are reproduced with the relative amplitudes in Fig. 3 for display on an oscilloscope. If the disc is running eccentrically and/or the head is not accurately on the centreline, the replay amplitude U 1fi  of the signals 4, 6, 8 differs from that U 1fo  of the signals 5, 7, 9 and to achieve optimum positioning the head 13 is shifted until the difference of such amplitudes for group n of the test signals is equal to such difference for group n+N/2 and the head (13) is then locked in position, N being the number of groups I, II &c. (each consisting of signals 1 to 9) in the test track. The replay signals U 2fc  corresponding to test signals 1 and 3 are used for azimuth adjustment of the head (13).

Abstract: 137,508. Thorens, H. Jan. 4, 1919, [Convention date]. Pocket igniters, frictional.-A friction wheel g on a bracket f on the reservoir c carries pins, which are engaged by a hook i pivoted with considerable pivot friction to a spring-operated hinged lid b, the engagement only taking place after the moving parts have acquired speed, so that a sudden rapid rotational movement of the friction wheel is produced. The pyrophoric block is carried by a claw f<1> on the bracket f and is pressed against the friction wheel by an extension on the hinge spring. When the lid is closed, the pivot friction causes the hook to move with the lid until it rests against the top of the reservoir. When the lid is held partly open, the hook may be disengaged from the wheel pin, so as, when the lid is released, to allow the friction wheel to be removed from its axle and the pyrophoric block from its holder. The removable burner d consists of a nozzle on a split tube fitting in a short neck on the reservoirs. The split tube guides the wick for a considerable length and prevents it from falling back into the reservoir if consumed excessively. An extinguisher is carried by one end of the hinge spring.
