Title: Thermal safety switch device for electrical apparatus
Inventor: BANYARD AUGUSTUS WILLIAM HENRY
IPC: H02H5/04
Filed: 1956-10-09
Abstract: 800,247. Automatic circuit-breakers. LOEWY ENGINEERING CO., Ltd. Oct. 9, 1956, No. 30745/56. Class 38 (5). A thermal switch suitable for protecting the conductors of an induction heater, comprises a pillar or stud 2 attached to the conductor 1 and carrying a fusible nut 3 which normally holds a bridging contact 7 across two fixed contacts 5a, 5b or an insulating base 4. Excessive heat from the conductor 1 passing up the stud 2 melts the nut 3 so that a spring 8 drives the nut 3 and contact bridge 7 upward to open the circuit 6. The spring 8 and contact bridge 7 are insulated from the stud 2 and nut 3 by a bushing 9 having a recessed head 9a to form a seat for the nut 3. A nut 10 may be provided to limit the movement of the other components on the stud 2. In Fig. 3 (not shown), a number of the switches are mounted on different parts of an induction heater coil with the switches in series completing the circuit of a relay in the supply contactor coil circuit. The switch may alternatively be normally open.

Patent GB-1080466-A (GB)
Title: Fluoridated dentifrice
IPC: A61Q11/00
Filed: 1964-08-04
Abstract: A dentifrice composition comprises sodium fluoride and stannous fluoride with an excipient which is substantially free from alkaline earth metal compounds capable of reacting with the said fluorides, under the conditions of use of the composition.  The excipient is preferably also free from other metal compounds which will react with the fluorides to yield fluorides having a water solubility below 1.25 gms./litre at 25 DEG C., particularly compounds of Ni, Fe, Cu, Pb, and Mg.  The term "substantially free" indicates that traces of the interfering compounds present as impurities &c. are permissible, but the affects of such traces are suitably mitigated by inclusion of precipitating agents therefor in the excipient, such agents being disodium phosphate and sodium hexametaphosphate.  Suitable excipients are white p  silica, silica gel, TiO2, sodium alginate, sulphonated lauryl alcohol, sodium phosphates, and glycerine, and the composition has a pH of 7.5 to 9.0.  The dentifrice is usually in the form of a toothpaste; an Example is given for preparing a tooth paste containing sodium, stannous, and manganous fluorides and all of the said excipients.

Abstract: 1,162,607. Character recognition. INTERNATIONAL BUSINESS MACHINES CORP. 12 July, 1967 [14 July, 1966], No. 31978/67. Heading G4R. A group of printed encoded characters on a document includes at least one check character, and each character is represented by a fixed number of code positions to each of which is allocated a predetermined one of a plurality of code elements and the check character has its code elements so selected that for each code position the number of times a selector code element occurs in the characters other than the check character, bears a predetermined relationship to the code element in the corresponding code position in the check character. Legible characters printed on a document are each constructed from seven vertical strokes with parts missing to provide the character shape, each of the six gaps between adjacent strokes having one of two breadths, the combination of breadths identifying the character to character recognition apparatus. A group of the characters is augmented by a further character the nth gap of which (for each n) provides a parity check for the nth gaps of the characters in the group. As each character is read it is converted to six binary pulses which are inserted into a shift register and then passed out in parallel to a set of six bi-stables each of which performs a parity check for a respective gap position. A special symbol following the augmented group of characters on the document causes an error signal to be produced if any of the six parity checks shows an error, and resets the bi-stables.

Abstract: 313,139. Ramsdell, T. S. June 8, 1928, [Convention date]. Lap - forming apparatus. - In the lap mechanism for a scutcher or like machine automatic means is provided to sever the lap after a definite length of lap has been wound, to eject the wound lap, to place an empty lap rod in position, and to curl the freshly severed end of the lap around the lap rod. The lap 75, Fig. 1, is passed through the calender rolls and under an idle roll 18, which rests more heavily on the carrier roll 12 than on the calender roll 17, to the lap rod 20. The roll 17 carries a worm 31 driving a vertical shaft 33 on which is mounted a disc 34, Fig. 4, provided with a notch 35 adapted to be engaged by a rod 37. The gearing is arranged to cause this to occur when a definite length of lap has been wound. When the rod 37 moves it rocks a lever 38 and closes a clutch 41, 40 causing the driving shaft 11 to impart one complete revolution to a control shaft 30. During this revolution of the shaft 30, (a) a cam 45, Fig. 2, depresses a lever 27c and operates the brake lever 27 releasing the brake 26 from the brake wheel 25, the lever 27 being held down by a catch 28; (b) a member 85, with a lug adapted in the rotation of the shaft to engage a notch in a spring controlled member 81 allows it to move and operate through an arm a clutch 77, 78 and drive the shaft 24 through a chain 83, raising the weight-racks 21; (c) a cam member 47, Fig. 2, at a certain stage allows movement along the shaft 30 of a spring-controlled member 48 which by an arm 51 closes a clutch 53, 54 and drives the carrier roll 12 through gears 55, 56 at an increased speed and the lap being held by the roll 18 is thereby severed-the normal drive for the carrier roll 12 being through gears 58, 59 controlled by a ratchet 61-; (d) cams 44 engage arms 66 and operate through links 65 levers 62 which eject the wound lap and deposit it in the receiver 73; (e) an eccentric 68 operates a bell crank lever 70 and lifts arms 71 to deposit a fresh lap rod 20<a> in position; (f) the shaft 34 is declutched and the racks 21 descend by their own weight and at the lowest point disengage the catch 28 and allow the brake 26 to be reapplied; (g) the arms 71, which carry a member 72, bring such member against the new lap rod, and cause the end of the lap to be curled round the rod; (h) the arms 62 swing back into their normal position and the clutch 41, 40, controlling the shaft 30, is opened.
