Abstract: 306,015. Nicholson, A. Nov. 14, 1927. Band clips.-Relates to means for protecting from wear the bottoms of kettles, pans, or other cooking vessels. A metal surround B, adjustable. in length so that it can be fitted to different vessels or can be adjusted upon the same vessel, is applied to the bottom edge of the vessel and may depend below the bottom, terminating in a wired edge, or may embrace the bottom corner. The device may comprise a band or may consist of a number of separate sections connected together by one or more metal straps. In the case where a band is employed any suitable means for effecting the adjustable connection of the ends may be made use of, several examples being described below. The device may be provided with further means for retaining it in position on the vessel, the metal straps C holding in place the sectional device of Fig. 2, and the interlacing means for holding on the band of Fig. 3, being examples. The protector device may be lined with asbestos or other suitable material or composition which may, if necessary, be coated with an oil paint to cause the device to adhere to the vessel. Figs. 5 to 7 show methods of adjustably connecting the ends of the divided band form of the device. According to Fig. 5<a> a small screw-bolt is passed through one of the holes in the end B' and through a longitudinal slot in the doubled end B, and is secured in a hole in an eccentric B2 disposed within the folded end. Adjustment of the band is effected by turning the part B2 by means of a suitable implement. In the form shown in Fig. 6, D-shaped holes are formed in the ends of the band, a disc, Fig. 6<a>, being disposed at one side, and a second disc, Fig. 6<b>, on the other, the lugs of the first disc being passed through the slots of the second and turned over. Rotation of the two discs effects the adjustment. Fig. 7 shows a third method. A metal strip B1 attached to one end of the band is adapted to be wound upon a split pin B4 mounted in openings in the sides of a sheet-metal fitting B3 attached to the other end, a hookshaped metal strip (not shown) being employed to lock the pin B4 when the required adjustment is effected. Fig. 4 shows a means for securing the upper attachment-band shown in Fig. 3, a tongue formed on a buckle 4<a> being adapted to enter a slot in the other end of the band. Reference has been directed by the Comptroller to Specifications 2253/09, 131,665, 140,877, and 163,960, [all in Class 66, Hollow-ware].

Title: Improvements relating to processes for the manufacture of leavened bread
IPC: A21D2/24
Filed: 1929-10-11
Abstract: 337,930. Gill, H. A., (Standard. Brands, Inc.). Oct. 11, 1929. Cereal, vegetable, and yeast preparations.-In making leavened bread, a small quantity of urea is mixed with the flour, yeast and other ingredients. Less urea may be used if urease is also added to the mix; for example to a mix containing 300 lbs. of flour 0.5 urea alone, or 0.2-0.25 1bs. of urea and 0.2-0.25 Ibs. of urease, are added. The urea allows corn sugar, pure maltose and other sugar substances to be used in the mix in place of cane sugar, a satisfactory crust colour being obtained. To counteract the effect of the ammonia liberated by the urea on the hydrogen-ion concentration of the mix, a small amount of a relatively insoluble acid substance, e.g. mucic acid or a mixture of mucic acid and acid calcium phosphate, may be added. The urea, urease and mucic acid may for convenience first be uniformly distributed in a filler material, e.g. flour, sugar or corn starch. A portion of the filler may be soy bean meal which will furnish urease.

Title: Electrically heated tank furnace for the melting of quartz
IPC: C03B5/033
Filed: 1959-09-11
Abstract: 860,740. Electric resistance furnaces. PATENT - TREUHAND - GESELLSCHAFT FUR ELEKTRISCHE GLUHLAMPEN. Sept. 11, 1959 [Sept. 17, 1958], No. 31050/59. Class 39 (3). Uneven expansion of heater wires disposed parallel to the axis of a cylindrical crucible in a tank furnace is compensated for by fixing each wire rigidly to the lower part of the furnace casing and arranging each of the wires to be tensioned by a two-system tensioning arrangement designed so that only a stronger system operates whilst the wires are being heated, and a weaker system only being effective whilst the. furnace is in operation, the systems being so arranged that the tensile stress of the weaker system is added automatically to that of the stronger system. The tungsten wires are sealed into guides 17, which slide into apertures 19 in an annular furnace cover 27. The guides in one form extend through springs 29, and 31 separated by an apertured disc contained in an enlarged cavity 18 of the aperture 19, the spring 31 which is the weaker spring abutting at its upper circumference against shoulder 22 of the guide header 21, the stronger spring 29 abutting at its lower circumference against shoulder 20 of aperture 19 at the bottom of cavity 18. When the wires are heated the tension is maintained in them by spring 29 which extends forcing, the disc 30, and spring 31 upwards, the abutment of spring 31 against shoulder 22 forcing the guide 17 upwards. When the heating has been completed the wires have expanded such a distance that the disc 30 will abut against the end of sleeve 28, positioned for that purpose, and further expansion of the heater wire during operation of the furnace due to realignment of the metal crystals in the wire will be compensated for by spring 31 which will then commence to extend. In another form the main spring 29 is dispensed with and the wires are suspended from a spring loaded guide and rigidly clamped in the bottom of the furnace which is not fixed to the casing, but suspended in place by virtue of the connection of the wires. As the wires expand tension is maintained by the downward movement of the suspended parts of the furnace casing, uneven expansion of the wires being compensated for by the spring means thus preserving a substantially uniform tension in each wire. The furnace preferably works in an atmosphere of hydrogen with or without nitrogen, so a copper sealing rind, or an oil seal are provided to ensure that the furnace, enclosure is gastight. The furnace heater preferably comprises 32 heating wires each individually suspended as shown, and the furnace is designed for the melting of quartz or quartz-like glasses having a high silicic acid content. Electric leads 25 are provided to the top of the headers 21 as shown. The furnace casing comprises many annular chambers for the passage of cooling fluid such as water The wires may be of tungsten and 2.8 mms in diameter, each designed to carry a current of 150 amperes.

Title: Improvements in or relating to opto-electronic semiconductor devices
IPC: H03K17/78
Filed: 1960-09-09
Abstract: <PICT:0967438/C4-C5/1> An opto-electronic semi-conductor device comprises a PN recombination radiation source 1 constituting the electric input integrally combined with a photo-conductive member 2 coupled optically to the source 1 and constituting the electric output, in which the member 2 comprises a semi-conductor body of which the energy gap is equal to or greater than the energy value of radiation quanta produced by the PN source 1 and which has activator centres producing energy levels between the valence band and conduction band for the relative radiation quanta.  The PN radiation source 1 and the photo-conductive member 2 can be formed from the same semi-conductor material and integrally combined in a single common semi-conductor body.  The activator centres are incorporated substantially in that part of the photo-conductive member 2 which coincides with the normal current path which would otherwise be provided between the electrodes 5 and 6 in the absence of radiation. The photo-conductive member 2 can be of a substantially compensated activated semi-conductor, i.e. a semi-conductor activated with an impurity of a given type and to which a second impurity is added to render the semi-conductor substantially as high-ohmic as possible. In the example shown the PN radiation source 1 comprises a P-type electrode 3 consisting of a metal contact 3a and an associated P-type semi-conductor region 3b, an N-type electrode 4 consisting of a metal contact 4a and an associated N-type semi-conductor region 4b, and an intermediate high-ohmic substantially intrinsic semi-conductor part. The two members 1 and 2 may form part of a single body.  The member 1 can consist of substantially intrinsic Ge, the electrode 3 being formed by alloying In containing a few per cent of Ga, and the electrode 4 being formed by alloying Pb-Sb or Pb-As.  The member 2 can consist of Si and in the normal current path between the electrodes 5 and 6 in the absence of radiation, Zn in an atomic concentration of approximately 10-5 is incorporated by diffusing Zn into the member 2 only from those surface portions which are intended to be covered by the electrodes 5 and 6.  An atomic concentration of approximately 1.9 x 10-5 of P can be added to form a compensated semi-conductor. Alternatively the device can be formed from a single body of high-ohmic Si in which one part is used as the photo-conductive member 2 and the other part as the radiation source 1, the P-type electrode of which is obtained by alloying Al and the N-type electrode by alloying an Au-Sb alloy.  The device can comprise more than one PN radiation source 1 and/or more than one photo-conductive member 2.  Electric feedback coupling can be used to produce a regenerative effect for providing bi-stable elements, oscillators and multi-vibrators.
