Convention date, Dec. 29, 1928. Void [Published under Sect. 91 of the Acts]. [Class 131.] A hair-waving device comprises a pair of laterally displaceable members c, Fig. 1, on which the hair is wound, the members being connected together by links b, b<1> and provided with slotted covers g secured on the hair by bolts i adapted to engage in slots k. The members c are provided internally with electrical or other heaters, and are covered with damped material before use, the material being retained in position by pivoted wire loops v. When wound on the members c, the hair is forced inwards between the members by a clip d, and the members c are then displaced laterally, so that the strands of hair are brought into an oblique position and an undulating wave is formed. To prevent the escape of vapour, the device is enclosed in a clasp r, Fig. 6, comprising a pair of limbs pivoted together at s and provided with finger grips t. Paper or the like may be wound on the hair before applying the clasp, or the clasp may be lined with interchangeable paper or the like.

Abstract: 1,197,455. Measuring temperature. NIPPON CARBON CO. Ltd. Sept.1, 1967 [Sept.30, 1966], No. 40012/67. Heading G1D. A pyrometer for measuring temperatures up to 3, 000‹C. comprises a temperature responsive member consisting of two elements 8, 9 which are made from anisotropic pyrolitic graphite and which expand differentially with temperature by virtue of the fact that the element 8 is disposed with the axis of expansion parallel to the plane of deposition of the graphite, whereas the element 9 is composed of a stack of plates of pyrolitic graphite disposed with the axis of expansion at right angles to the plane of deposition of the graphite, the differential expansion of the elements 8, 9 being transmitted to a dial gauge indicator 7 as a bracket 4 by means of a coaxial rod 2 and tube 3 intermediate portion. The pyrolitic graphite may be made by deposition at a temperature of 2,100‹ C. and this may be followed by heat treatment at 3, 000‹ C. Also, the graphite may contain 0À01 to 3% by weight of boron, molybdenum, silicone or bromine. The rod and tube 3 are also preferably of graphite, i.e. artificial, natural, recrystallized or pyrolitic graphite and are arranged to have the same coefficient of thermal expansion. A number of other refractory materials which may be used for the rod 2 and tube 3 are also specified in the Specification. In alternative embodiments the element 8 may be made integral with the tube 3 and the dial gauge 7 may be replaced by a differential transformer whose output is fed to a recorder. In addition the member 8 may be coated with silicon carbide for protection.

The zero flow pressure of the pump 3 is approximately equal to the pressure difference between the static head of water in the surge tank 1 and the pressure in the adjacent part of the feed circuit 7. In operation, the pump works continuously in the direction urging water from the surge tank 1 to the feed circuit 7, but should a surge due to load variation cause an increased pressure in the circuit 7, the water flows against the action of the pump from the circuit 7 to the tank 1.

The pick up arm is coupled at its end remote from the stylus to the apex of a speaker cone and the arm is held in freely sliding engagement with carriage 58 by resilient finger 71. The carriage is hinged at one end to a slide 55 which carries a pinion 45 rotatable by knob 48. The pinion meshes with a rack 46 extending along the guideway 50 so that by rotation of the knob the slide and hence the carriage can be moved to positions defined by members 98 each associated with a record band. At the other end of the carriage a bracket 69 supports a cross arm 70 which slides between bars 67, 68, &c. on an actuating lever 62 which is normally urged upwardly by spring 95. In the up position of the lever 62 the carriage is inclined and the pick up arm is raised clear of the record and is drawn by cord 89 into engagement with a stop 88 in the carriage.

Abstract: 1474773 Limiting maximum demand of a system of loads WESTINGHOUSE ELECTRIC CORP 1 Oct 1974 [12 Oct 1973] 42533/74 Heading H2H A control arrangement for limiting the power demand of a system including a plurality of switchable loads, comprises means for switching at least one load between ON and OFF conditions, means for establishing a predicted final power demand at the end of a predetermined demand period, e.g. 15 mins., in relation to present power consumed for successive increments of energy during the demand period, means for establishing a demand error by reference to a predetermined power demand limit and to the predicted final power demand, the means for switching the load operating in accordance with the sign of the demand error. The loads are also controlled by automatic switching means which operate independently of the above control to prevent e.g. a load being OFF for greater than a predetemined time, and the present energy consumption monitored by the system is modified to take account of the loads shed or picked up. A base, i.e. non-controllable, load is present and its consumption also included in the monitoring. In a preferred embodiment an electric meter provides a pulse for each turn of a meter wheel and hence a train whose frequency is dependent upon the rate of energy consumption. The intervals between the previous 3 such pulses is used to determine the gradient of the KWH against time curve which is then used to provide a continually up-dated prediction of the final demand and the end of the period. This period is divided into 3 subperiods. A first period where no control is exercised, a second period where control against a reduced final consumption target is effected, and a third period where this reduced target is increased step-by-step to the predetermined target. A dead-band between two particular consumption curve tangents where no control is effected may also be used. The system is computer controlled and all loads are given a priority in a most-least sheddable table included in the programme. Comprehensive flow-charts of the computer operation are provided in the Specification, Figs. 12, 13, 14 (not shown).

Abstract: 1523500 Multi-type particle fluidised bed BATTELLE DEVELOPMENT CORP 13 Oct 1976 [21 Oct 1975] 42588/76 Heading B1F [Also in Division C5] A method of operating a fluidized bed, e.g. for the efficient reaction between at least two reactants comprises (i) forming an entrained or lean phase fluidized bed in a first space region e.g. as shown as I in Fig. 2, containing a first solid bed particle component 60, (ii) forming in a more limited space region II within the first region a dense phase fluidized bed containing a second solid bed particle component 62 essentially comprising a material having longterm physical and chemical stability in the fluidized bed so as to be substantially non- agglomerating and not subject to substantial attrition therein, (iii) providing a recirculation path e.g. via separator 36, reservoir chamber 74 and recycle conduit 76, for the first particle component from the first space region through the dense fluidized bed in the more limited space region and (iv) operating the fluidized bed at a velocity such that the second component particles are effectively retained in the dense fluidized bed in the more limited space region, whereas the first component particles recirculate and interpenetrate therethrough, commingling with the second component particles. Most preferably the fluidized bed is used for the gasification of a carbonaceous material, the bed being fluidized with the gaseous reactant e.g. air and heat being withdrawn as an energy product. It is preferred that most of the carbonaceous material e.g. coal is burned in the dense fluidized bed. If the coal contains sulphur a sulphur sorbent e.g. calcium and/or magnesium carbonate may be fed into the system. The bed particle components may be an oxide of iron, aluminium oxide, nickel, nickel oxide or a carbonate of calcium and/or magnesium. Both components may be of the same material, in which case the first component is of smaller particle size than the second component.
