Title: Expandable wire thermal control device
IPC: A47J37/08
Filed: 1959-02-10
Abstract: 879,403. Thermal switches. SUNBEAM CORPORATION. Feb. 10, 1959 [July 14, 1958], No. 4675/59. Class 38 (5). [Also in Groups VI and XIII] A switch, especially for controlling an electric toaster, comprises spaced parallel wires 31 responsive to the surface temperature of the bread and connected to frame members 19, and means responsive to the spacing of members 19 for producing a snap-action movement. As shown, the lower member 19 is fixed and carries two snap-acting blades 21 connected at their upper ends to the other member 19, the wires 31 being stretched between members 19. Blades 21 are flexible only near their ends and centres, and the centres are connected by a rod 23. The blades are stressed so that they normally occupy the full-line positions, where contacts 37, 39 are held open by the rod 23. When the bread is inserted, the rod 23 is pushed to the left manually or by depression of a bread carrier which is then latched, the blades 21 then taking up the dotted positions. When a certain temperature is reached, the expansion of the wires allows the blades to snap back over centre to re-open the contacts and to trip the latch holding the carrier. The operating temperature is set by adjusting an abutment screw 53b.

Title: Transfer materials
Inventor: REED KENNETH JAMES
IPC: B44C1/17
Filed: 1964-02-04
Abstract: A transfer material comprises a carrier sheet supporting a layer or one or more indicia in a transferable material which is an ink containing a pressure-sensitive adhesive ingredient.  The exposed surface of the transfer material is of low tack and the adhesive properties of the material are balanced in relation to the surfaces of the carrier sheet and a receptor sheet so that the material is not transferred bodily to the contiguous surface of the receptor sheet under normal finger pressure, but only under the application of substantial pressure, e.g. 50 p.s.i., by a stylus &c. to the rear surface of the carrier sheet.  The carrier sheet may be transparent or translucent or may be of paper such as glassine, vegetable parchment, or kraft glassine, uncoated or coated on at least one side or impregnated with a polymethyl siloxane or a chromium complex.  The sheet may also consist of numerous plastics materials including polythene, cellulose acetate or polyvinylidene chloride.  The ink includes a tacky presence sensitive component, a low tack or non-tacky component, a high tensile strength polymer, and a pigment: numerous examples are given of suitable ink compositions.  The ink may include a high boiling point plasticizer, e.g. di-isobutyl phthalate, which exudes towards the outer surface of the indicia to maintain it tacky, a polymerizable system of which the polymerization is air inhibited, or a polymer-catalyst system wherein the catalyst content is inadequate to bring about complete polymerization. In one example, the ink includes polyvinyl butyral, microcrystalline wax, carbon black, polyvinyl isobutyl ether, and a solvent. The indicia may be multi-coloured with the multiple impressions either superimposed or side by side.  The transfer may be in tape form.

Title: Phenol-formaldehyde resins
IPC: C08G8/24
Filed: 1943-03-29
Abstract: Resins which can be blended with drying oils to yield quick drying varnishes forming durable films of good resistance to water, acid and alkalies are prepared by heating a mixture of o-cresol with p-hydroxydiphenyl or with o-hydroxydiphenyl or with a mixture of p- and o-hydroxydiphenyls, the o-cresol constituting 20-90 per cent by weight of the mixture, with aqueous formaldehyde in the presence of a strongly alkaline catalyst, until the resole formed separates from the aqueous layer, removing the resole from the aqueous layer and heating it under dehydrating conditions.  About 0.9 to 1.1 mols. of formaldehyde are generally used per mol. of mixed phenols.  Suitable catalysts are caustic soda, ammonia, caustic potash, calcium hydroxide, or trimethyl benzene ammonium hydroxide.  The reaction is preferably performed under a reflux condenser.  Dehydration may be performed by heating in a stream of inert gas such as carbon dioxide up to a temperature of 130 DEG  C.  The resin may then be hardened for storage by heating for 5-75 minutes at 150 DEG  C., or it may be cooked with a drying oil, e.g. tung oil, to yield a varnish to which conventional driers such as cobalt or lead linoleates or naphthenates may be added.  Examples 1-8 give particular details of proportions, times and temperatures for the preparation of resins from mixtures of o-cresol with p-hydroxy-diphenyl.  Example 9 describes the preparation of a resin from a mixture of o-cresol with o-hydroxydiphenyl.  Example 10 describes the preparation of a resin from a mixture containing o-cresol, p-hydroxydiphenyl and o - hydroxydiphenyl.  Specifications 347,737, 417,122, 433,539 and 467,081 (as open to public inspection under Sect. 91) are referred to.

Title: Improvements in or relating to subscriber's line circuit arrangements
IPC: H04Q3/00
Filed: 1955-02-23
Abstract: 765,404. Automatic exchange systems. PHILIPS ELECTRICAL INDUSTRIES, Ltd. Feb. 23, 1955 [Feb. 26, 1954], No. 5434/55. Class 40 (4). A subscriber's line circuit contains a transistor which responds to current change round a calling subscriber's loop to provide a line-finder start signal. As shown, the P-N-P transistor T1 is normally cut-off when its base is at near ground potential. When the calling loop is completed the base potential falls to - 30 v. and heavy current flows between collector and emitter to lower the marking potential. on the c-terminal to - 30 v. The potential of the common point P and hence of the base of the N-P-N transistor T2 also rises to change the transistor T2 from the non-conducting to the conducting condition, thereby operating relay X which starts a line-finder OZ in known manner. The line-finder hunts for the - 30 v. marking and when this is found contact bc operates to apply a heavy negative busy potential V6 sufficient to cut off the transistor T1. Transistor T2 is thereby cut off and X released. A similar busy potential may be applied from a final selector. The test device in the line-finder must be arranged to operate only in the prescribed range of calling voltages which lies somewhere between - 20 v. and V6. The test device in a final selector must respond only to a range of values corresponding to the normal condition i.e. approximately - 20 v. The busy potential V6 may be arranged to differ according to the nature of the call (e.g. trunk or local) in which the subscriber is engaged.

Title: Method and apparatus for determining at any given moment what length of a continuous strip of material has passed a given point
IPC: G01B5/04
Filed: 1964-02-11
Abstract: <PICT:1060971/C1/1> In the production of a continuous ribbon of glass on which one or more operations such as fault-detecting, scoring, breaking and labelling are to be carried out, there is provided apparatus for determining at any given moment what length of a moving strip of glass has passed a given stationary point of reference. This apparatus comprises a continuous measuring device, e.g. a wheel rolling on the strip of glass 1 and a calibrating device being intermittently compared with the information supplied by the continuous measuring device and the error found by this comparison is used to adjust the continuous measuring device.  This is effected by feeding to a bevel gear 25, forming part of the transmission between a wheel 12 and an indicator 21, an angular correction for correcting the cumulative errors and by applying a speed correction for adjusting the transmission ratio of said transmission.  The calibrating device may record equidistant marks on the strip, the distance between the marks corresponding to the length of a reference base fixed relative to a working position. Alternatively (see Fig. 1, not shown) a succession of lengths may be recorded on the strip by means of a moving member 7 intermittently locked with the strip.
