IPC: B01D3/00
Filed: 1916-04-11
Abstract: 105,395. Sadler & Co., and Bellerby, J. April 11, 1916. Hydrocarbons, distilling; progressive evaporators.-In the fractional distillation of crude benzol and other volatile liquids, the benzol flows through a preheater c, a primary still b, and a secondary still p in succession, the major portion of the steam used to effect the main distillation in the still b being condensed therein and passing away as water with the residual liquid to the still p, where the water is revaporized. The vapours from the still b are partly condensed in a coil f in the preheater c. The resulting liquid consisting of crude toluol, flows away through a trap i; the remaining vapours, consisting of benzol, pass to a separate condenser. The vapours generated in the still p consist of crude solvent; the residue is stripped creosote. The still b is heated by a steam box u and by free steam admitted by a pipe n. The still p is fitted with partitions q by which the liquid is forced to take a zigzag path, and is heated by a coil r through which steam under a pressure of, say, 401b. circulates.

Title: Improvements in and relating to doughnut frying-machines
IPC: A21B5/00
Filed: 1941-04-25
Abstract: 550,283. Frying machines for doughnuts. LOWE CORPORATION, J. April 25, 1941. No. 5362. Convention date, Jan. 30, 1941. [Class 28 (i)] A doughnut frying-machine comprises a conveyer for moving doughnuts through the machine during the cooking operation, a turnover device intermittently rotated by the movement of the conveyer for turning the doughnuts over whilst cooking and a weighted lever bearing upon a cam in order to impart a quick rotation to the turnover device at the point of inversion of the doughnut, the weighted lever finally centring the turnover device in its correct position of rest. As shown in Fig. 7, a doughnut cutter 126 deposits the doughnuts in an elongated frying kettle 100 where they are engaged, whilst floating on the frying fat, by the spaced cross flights of a chain conveyer 109 and are pushed along to the turnover device 205. On approaching the turnover device the momentum of the leading doughnut is arrested by a curved lip 172, Fig. 9, so as to remain in contact with the propelling cross flight 110. During its further advance, the cross flight depresses the lip 172 and pushes the doughnut into the position 127a immediately above a turner blade 184a mounted on a shaft 150. A cross flight 115 engages and rotates the turnover device thus raising the doughnut out of the fat towards the vertical position. At the same time a cam 181 on the shaft 150 raises a weighted lever 175 until, at a point beyond the dead centre of the cam, the weight of the lever imparts a quick rotation to the turnover device to flip the doughnut off the coacting turner blade in an inverted position into an advance flight compartment 114, the weighted lever finally arresting the turnover device in the position shown. During the inverting action a ledge 187a acts as a momentary rest for the doughnut positioned upon the turner blade. Should the turnover device over-step, the approaching crossflight rides up bevelled end walls forming part of the turner blade and rotates the turnover device back to the correct position of rest. During the continued advance of the conveyer, the reverse side of the doughnut is cooked, and at the far end of the kettle the doughnut is transferred by a conveyer 122 to a delivery shoot. The cam 181 may be replaced by a notched cam of swastika shape. Specification 543,772 is referred to.

Abstract: 798,795. Electroluminescence. GENERAL ELECTRIC CO., Ltd. Feb. 24, 1956 [Feb. 25, 1955], No. 5735/55. Drawings to Specification. Class 39(1). An electroluminescent indicating device associated with a diaphragm, chart, scale, map or picture comprises two sets of lines of conducting material, one set transverse to the other and electroluminescent material between them. Application of a suitable A.C. or D.C. voltage between one line of one set and a line of the other set gives a point of light at the point of intersection or a point of higher brightness than that at any point of intersection with other lines. One of the sets may be of transparent conductive material, e.g., stannic chloride vapour applied with moisture to a glass sheet, equally spaced strips being removed by shotblasting through a mask. The phosphor ZnS/Cu dispersed in a transparent resin is applied by spraying and a number of strips of conductive material such as silver, copper, or graphite in a binder, or aluminium, applied by spraying or evaporation through a mask. A second glass plate is fixed thereover with wax or resinous adhesive. The luminescent material may be a continuous layer, or disposed as lines or spots behind the conductive lines or points of intersection respectively. It may comprise crystals of luminescent material coated with an electrolyte. The two sets of lines may be orthogonal or inclined and the lines may be curved, e.g., hyperbolic as in phase difference navigational charts and be on part cylindrical or partspherical surfaces. The non-transparent set may be wires. Specifications 717,169, 717,170, 746,502, 748,834, 751,047 and 788,659 are referred to.
Patent GB-825940-A (GB)
Title: Improvements in or relating to bearing arrangements for measuring instruments
Filed: 1956-02-24
Abstract: 825,940. Measuring instruments. GOSSEN & CO. G.m.b.H., P. Feb. 24, 1956 [Feb. 26, 1955], No. 5813/56. Class 37. [Also in Group XXV] A rotatable coil of a measuring instrument is suspended by a strip or thread or between two tensioned strips, and is held against displacement laterally from its normal pivotal axis by a bearing arrangement comprising a pair of pivot pins and a pair of corresponding bearing cups, either the cups or the pins being freely movable axially in a guide hole in a stationary part of the instrument and being urged apart by resilient means so that each pin and its cup normally engage on the pivotal axis but so that axial yielding of either the cups or the pins occurs when lateral forces on the coil exceed a predetermined amount. In one embodiment the coil 1, suspended by a strip 3 from a spring 4, has inwardly directed pins 9a, 9b which engage cups 10a, 10b, pressed lightly apart in the bore of a magnetic core 2 by a spring 11. The moving arm 7 carries a contact 8. There may be a second stronger coaxial spring which is shorter than the normal distance between the cups 10a, 10b but prevents the cups disengaging from the pins during excessive vibrations. The cup 10b, Fig. 2, has a jewel 12 with a conical cup 31 the angle α of which is at least 90 degrees, and a bearing ring 13, so that if the pin 9b is displaced laterally the cup 10b will slide upwards until the side of the pins engages the wall 13<SP>1</SP> of the ring 13, preventing damage to the point of the pin. In a modification the coil is arranged between tension strips to pivot on a horizontal axis. In an arrangement employing two vertical tension strips a mirror arranged on one strip reflects a light beam on to a light-sensitive cell. In an arrangement wherein the contact on the arm 7 closes a relay circuit an armature on the arm enters a slot in a magnetic screen in an attracting magnet at the predetermined angle of deflection causing closure of the contacts.

Title: Protective and safety arrangements for high voltage output circuits of transformers
IPC: H02H7/04
Filed: 1937-02-26
Abstract: 480,828. Protective cut-out arrangements. WILLIAMS, H., and MAPLE & CO., Ltd. Feb. 26, 1937, No. 5829. [Class 38 (v)] A safety-arrangement for the high-voltage output circuits of transformers, for example for supplying luminous discharge tubes, comprises an electromagnetically -operated switch controlling the input side and having its magnet shunted across the output in series with a spark-gap, the input-controlling switch being a manually resettable gravity mercury switch normally locked by the magnet-armature in closing position, but permitted to drop into current-breaking position upon the magnet being energized by an excess of output-voltage. The spark-gap 19 and coil 18 control a mercurytube switch 8 arranged in the circuit of primary 1 and carried upon a lever 13, which is pivoted at 14 and provided with an undercut 13a which rests on a pin 15 projecting from the unattracted armature 16 to hold the switch closed. When the gap breaks down, the armature is attracted from its back-stop 17a, so releasing lever 13 which falls, aided if necessary by a tail 21 on the armature, into the position in which the switch opens the primary, Fig. 3. The arrangement of pivot 17 is such that the armature remains in its attracted position and so holds the lever in its depressed position. The device is reset by depressing the free end of lever 13, which, through the armature-tail, restores the armature to retaining position. The gap may be located in a spark-damping or fireproof chamber, or may be located in a chamber containing an explosive gas or material which, on discharge across the gap, explodes and displaces a piston-like movable container-wall to actuate a switch. The switch may alternatively divert the supply to earth and operate a fuse or circuit-breaker.

Class 80 (4) [Also in Group VIII] In a machine having a plurality of rotating disc knives 126 for cutting sheet material, for example, leather, and a guard member 184 with a transparent window 188 adapted to protect the operator from the rotating knives, interlocking mechanism is arranged between the guard and the driving mechanism for the knives so that the knives cannot rotate until the guard is closed and the guard cannot be opened until the knives are at rest.. The guard 184 is pivoted on a horizontal rod 190, so that it can be raised to give access to the knives, and carries at its right hand pivot an eccentric stud 192 which operates a sheave 194 with a projecting arm 196 guided between a pair of studs 200. The arm 196 co-operates with the end 206 of a plunger 202 the other end 222 of which cooperates with a number of holes 224 in a driving gear 66 of the train driving the knives 126. When the guard is lowered into its guarding position the arm 196 is raised and the plunger end 206 is moved to the left by a spring into a position underneath it so that the guard cannot be opened under such conditions when the machine can be started. To open the guard the plunger 202 must be moved to the right by operating a projecting pin 216 to enter the end 222 into one of the holes 224 in the gear 66. To effect this operation the machine must be stopped and one of the holes 224 aligned with the plunger end 222. The arm 196 can then move downwards and allow the guard 184 to be raised.
