Classes 120(1) and 120(3) A sliver fault detecting device comprises an arm pivoted to a support member and having a member attached thereto over which the sliver is to be passed, the arm being pivoted in such a manner that an increase or decrease in the weight per unit length of a given length of sliver causes the arm to be rocked whereby a warning device is actuated. In the arrangement shown the device is applied to a carding machine and consists of a pillar 10 having mounted at its upper end a bracket 12 carrying a pivot member 14 to which is pivoted at 16 a balance arm 18 having two arms 20 and 22. The arm 20 carries a roller 24 whilst the arm 22 has a slot 26 which supports an adjustable balance weight 28. The arm 18 is formed centrally with a boss 34 from which extends a perdulum 36 carrying a weight 38. Adjustable stops 42 are provided and between these stops and the boss 34 are electrical contacts 46 and 47. When in operation a sliver 48 is passed over the roller 24 under a lower roller 50 and over a top roller 52. Any variation in the weight per unit length of the sliver causes the arm 18 to pivot about the pivot 16 thus making either of the sets of contacts 46 or 47 whereby an electric circuit is closed and a warning device operated. A time delay switch may be incorporated to prevent operation of the warning device in the event of a knot &c. passing. The device may also be used to correct the rate of feed of the sliver by controlling the driving motor or motors of the apparatus with which it is being used.

Title: Improvements in or relating to voice components for use in dolls or other toys
IPC: A63H3/28
Filed: 1951-05-04
Abstract: 694,989. Sound producing toys. SEDDON, R. F. Sept. 14, 1951. [May 4, 1951] No. 10515/51. Class 132 (iii). A voice component for a toy comprises a gravity-movablepiston carrying a thin flexible washer 24 which forms a seal between the piston and a cylinder 1. A passage 9 communicates at the lower side of the piston with a groove 10 in which is located a reed sounding device 12, 15. The top end of the passage 9 joins with a recess 20 which is covered by a diaphragm 21 having a hole 22 large enough just to permit the head 7 of a stud 5 to pass, through. When the piston commences to move down from the extreme upper end of the cylinder, the vibration of the reed 15 is small, since the reed is operated only by air passing through the piston via a hole 23, the hole 22 being blocked by the top of the stud 5. As the diaphragm clears the top of the stud air also flows between the neck 6 of the stud and the edge of the hole 22, a louder sound in the reed being produced. As the piston moves further down the hole 22 is again blocked, this time by the head 7 of the stud. During the remaining downward movement of the piston air flows freely through holes 22, 23 and a louder note is produced. Invertion of the device for resetting causes no vibration of the reed.

Patent GB-569308-A (GB)
Title: Improvements in and relating to vitreous compositions
IPC: C03C14/00
Filed: 1943-07-01
Abstract: An electrically insulating moulded vitreous product of the "Mycalex" (Registered Trade Mark) class having high dielectric strength, low power-factor and low dielectric constant, is formed by mixing mica, a fluorine-containing compound and boric acid or anhydride, all in a finely-divided state, and heating the mixture to reaction temperature whereafter the plastic heated mass is moulded to desired shape.  The amount by weight of the boric anhydride is substantially equal to that of the fluorine compound, or the weight of the boric acid is such as to form such weight of anhydride by the heating.  The fluorine compound may be cryolite or an alkali fluoride or silico-fluoride.  An example: 70 parts by weight of comminuted mica, 15 parts by weight of cryolite and 27 parts by weight of boric acid (yielding approximately 15 parts by weight of the anhydride) are mixed with, say, four parts by weight of water to form a smooth semi-solid mouldable mass which may be formed into blanks.  After drying, the blanks are raised to about 450 DEG  C. to drive off the water from the boric acid and are then raised to the reaction temperature of about 625-650 DEG  C.  The hot plastic composition is then put in moulds heated to about 400 DEG  C. and moulded under pressure.

Filed: 1922-04-18
Abstract: 200,888. Boyd, A., and Davidson & Co., Ltd. April 18, 1922. No Patent granted (Sealing fee not paid). Crops, storing.-A method of curing crops consists in stacking them soon after cutting and alternately allowing the stack to heat by natural oxidation up to a predetermined temperature and subjecting the stack to a current of cold air, which is forced into the centre of the stack, and which is cut off when the temperature falls to a predetermined level. As shown, the crops are stacked by means of a conveyer 18, Figs. 1, 2, and 3, and an adjustable deflector plate 28 around latticed frames 29 arranged in sheds of which three are indicated in Fig. 2, the conveyer being actuated by a roller 20, which is driven through belt-gearing from an oil engine in the power house 1. The engine also actuates a fan 9 which forces air through a passage 33 into a main 31 having damper-controlled branch conduits 32 leading into the frames 29. Electric thermometers 39 having adjustable maximum and minimum contacts are placed in the stacks and, on the temperature rising to a predetermined point, they actuate a warning bell, whereupon the attendant operates the plant so as to supply cold air to the stack or stacks which has or have heated up. On the temperature falling to a predetermined level, the thermometers actuate a gong, whereupon the attendant closes down the plant. In a modification in which the stacks, which are of conical shape, are built around tripod frames in the open air, the fan supplying the air to the stacks is driven by an electric motor, the starter of which is actuated automatically by means of electric contact thermometers placed in the stacks. In another arrangement, the stacks are of rectangular shape and are built around A-shaped latticed frames.
