Title: Improvements in and relating to felt hats
IPC: A42C1/06
Filed: 1948-03-04
Abstract: 634,016. Making felt hats. CARRINGTON & SONS, Ltd., S. R., and HULME, T. March 4, 1948, No. 6747. [Class 63] A process for making a felt hat having an upwardly curved brim whose rim is curled over and stitched to the upper side of the brim to form a roll, comprises turning a hat body inside out, placing it on a crownforming block, steaming the hat body to form a hat crown, and lowering the inverted body and block into a brim forming frame where part of the body which projects beyond the block is pressed outwardly and downwardly on to the frame to form a brim. The part of the brim projecting beyond the periphery of the frame is bent downwardly and pressed and secured by a piece of string in a circumferential recess formed in the side edge of the frame. The part of the body which projects beyond the string is bent upward outside the string and the rim of the brim is curled over on the the brim lying on the frame. The brim is fixed by an elastic band in this position and then it is steamed and allowed to cool, and set. The body with the curl of the brim on its underside is removed from the block and the curl is trimmed and stitched to the brim. The crown of the hat is turned rightside-out and reblocked and reframed to shape the curl which is now on the upper side of the brim. The hat is then steamed and allowed to cool and set.

Title: Improved process for the conversion of naphthenic hydrocarbons to aromatics
IPC: C10G35/06
Filed: 1943-04-29
Abstract: A naphthenic hydrocarbon fraction of boiling range 280-350 DEG  F is distilled to separate a plurality of fractions each of a boiling range not greater than 40 DEG  F. which are separably subjected to catalytic reforming in the presence of hydrogen to convert naphthenes to aromatics, the reaction products being distilled to separate fractions containing a major amount of aromatics from those containing mainly unconverted hydrocarbons. Catalytic reforming is defined as a heat treatment above 500 DEG  F. in presence of a catalyst to give a product of higher aromaticity. It may be effected under such conditions that there is no overall net consumption or a net production of hydrogen.  Substituted cyclohexanes are converted to the corresponding substituted benzenes by dehydrogenation while substituted cyclopentanes and cycloheptanes are also, at least in part, converted to aromatics. The boiling range of the initial fraction is selected so that the desired aromatics boil above or below the upper or lower limit respectively, whereby separation by fractionation is possible. This is exemplified by reference to the boiling points of some of the substituted cyclohexanes and the corresponding substituted benzenes.  A naphtha having an appreciable naphthene content is fractionated to remove the fractions boiling above 350 and below 280 DEG  F., and, to separate cuts of boiling range 280-315, 315-340 and 340-350 DEG  F. which are passed to storage tanks.  These cuts are fed separately to a reactor after admixture with hydrogen and preheating to 100-150 DEG  F. above the reaction temperature.  A suitable catalyst is alumina in any of its forms with oxides or sulphides of metals of Groups 4, 5, 6 or 8, especially Mo, Cr, W, V, Co or Ni.  The temperature is 850-1000 DEG F. with increased pressures up to 600 lbs./sq. in. and a feed rate of 0.1-3 vols. liquid oil/vol./hr. 1000-6000 c. ft. of gas containing 30-90 mol. per cent of hydrogen are passed per barrel of oil.  The products are cooled, gases separated for recycling, if desired after scrubbing out hydrocarbons, and the liquids fractionated to separate aromatics.

Title: Improvements in or relating to the tanning of skins and hides
IPC: C14C3/04
Filed: 1921-03-01
Abstract: 180,758. Hell, J. March 1, 1921. Mineral tanning; tanning with aldehydes, sulphite liquors, and other special chemicals; combination tanning processes; currying, impregnating, and the like.-Hides and skins are tanned by means of soluble magnesium salts and soluble carbonic-acid salts of other bases in the presence of water. A mixture of the dry salts may be introduced into a drum containing the wet hides, the moisture being sufficient to dissolve, the salts and render them active, or the hides or skins may be drummed successively in separate solutions of the salts. The process may be applied to partially-tanned hides, or may be combined with other processes such as tanning or treatment by cellulose sulphite liquors, formaldehyde, chrome, iron, or other mineral tanning-agents, or vegetable tanning-agents, used in admixture or separately. In an example, 100 kg. of unhaired hides are drummed for four to six hours or longer in a concentrated solution containing 21 to 22 kg. of magnesium sulphate and 7 kg. of sodium bicarbonate or 9 kg. of sodium carbonate, or the hides mav be first drummed in a solution of one of the salts, the other salt being added subsequently. This treatment may be followed by rinsing and oiling or by treatment with fat, grease &c. to which formaldehyde has been added, or the hides may be pressed out or exposed to the air, then coated or brushed over with cellulose sulphite liquor and afterwards rolled and greased. Alternatively, the cellulose extract may be added to the tanning mixture. Formaldehyde, chrome, alum or salts of iron, zinc or barium or small quantities of vegetable tanning materials such as oak extract may be added to the tanning mixture described in the example, or may be employed in separate solutions for subsequent treatment. In a further example the hides, after treatment with the mixed salts and formaldehyde, are steeped in milk of lime and then further treated as in the first example. The various processes are stated to produce heat-resisting qualities, durable graining or embossing &c., firm or soft texture &c. as required. Specification 2873/98 is referred to.

Title: Improvements in or relating to gramophones
IPC: G11B3/085
Filed: 1951-03-22
Abstract: 683,058. Gramophones. PHILIPS ELECTRICAL INDUSTRIES, Ltd. March 22, 1951 [March 29, 1950], No. 6892/51. Class 40 (ii). In a gramophone having a pick-up 8 which is movable parallel to the record surface on guide rails 9 and is movable by a manual control from an operative position on the record to an inoperative position off the record, and vice versa, the pick-up 8 has a movable member 31 which is engaged, when the pick-up is in the inoperative position, by the edge of a record 2 being moved edgeways on to the turntable 4, and the pick-up 8 is pushed against frictional resistance to the appropriate starting position over the record. The pick-up 8 is suspended from a carriage 11 movably supported between the guide rails 9 by means of rollers 12. Mounted on the carriage 11 is a rigid bracket 27, Fig. 3, from the end of which an arm 26 carrying the pick-up 8 is hinged. The pick-up 8 is lifted and lowered by means of a rod 13 under the control of a knob 16 which, by means of a rod 19, pinions 22 thereon and racks 23 along the upper edges of diagonally-slotted sliding members 20, causes the rod 13 to be raised and lowered in vertical slots 14. When the pick-up 8 is raised to the inoperative position, a pad 25 on the pick-up is pressed against the lower guide rod 9, so that movement of the carriage 11 is damped. In this position, the switch 32 of the motor 33 is "OFF." Upon a record 2 being inserted edgeways into the cabinet, the edge of the record engages the member 31 suspended from the pick-up 8, and pushes the pick-up against the friction of the pad 25 along the guide rods 9 so that it reaches the correct starting position for the record being inserted when the said record is located on the centre pin 5 of the turntable 4. Rotation of the knob 16 then serves to operate the motor switch 32, and lower the pick-up 8, the impact of which with the record is reduced by means of an eccentric disc, 29 mounted on the pick-up 8 forming part of the member 31. An alternative embodiment is described with reference to Figs. 9 and 10 (not shown) in which a conventional swinging pick-up arm is employed, the lifting and lowering being effected by a ring member encircling the bearing of pick-up arm shaft, and the motor is movable out of the cabinet on slides for the placing of the record, which then engages a depending member on the pick-up when moved back into the cabinet. When the motor has been restored to its playing position the turntable engages a driving belt and the pick-up is thus lowered onto the turntable.

Abstract: 1385250 Calibration scaling circuit PERKIN-ELMER CORP 17 Feb 1972 [1 March 1971] 7468/72 Heading G1U A calibration circuit, particularly for use with a spectrophotometer producing signals that do not vary with time, is characterized in that firstly during a calibration mode of operation the circuit automatically sets itself so that a standard signal V S  from the spectrophotometer is integrated linearly 60 for such a time that its integral equals a value V R , manually pre-set 10 into the circuit, and secondly during a subsequent measuring mode of operation an unknown signal VM from the spectrophotometer is integrated for the same period as was the standard signal, and thereby effectively given the same scale factor that was applied to the standard signal in order to bring it up to the desired pre-set value. Hence the output produced by the circuit during the measuring mode is V R V M /V S . As described, during the calibration mode, the standard signal Vs is integrated 60 and compared 70 with the signal VR manually pre-set on a potentiometer 10. When equality is reached, a trigger 80 is set on to energize its S output which opens a switch F4 so that a second integrator 110, which has also been integrating the standard signal V S  via a buffer amplifier 102 is isolated. Thus at the end of the calibration mode the standard signal V S  is stored on a capacitor Cl, and its integral, for the period that was necessary for the integral of V S  (obtained by integrator 60) to equal V R  is stored on a capacitor C2. During the measuring phase, the signal VM from the spectrophotometer is integrated in integrator 60 and the result displayed, via a contact 52 and a switch Fl, on a voltmeter 42, the period of integration lasting until a fresh integration by integrator 110 of the standard signal V S , now stored on capacitor Cl, equals the previous value determined during the calibration mode and which is now stored on capacitor C2. Equality of these signals is detected by a comparator 120 which sets the trigger 80 so that further integration of the measured value VM is prevented by opening of switch F2.
