Abstract: 644,706. Bottling. U.D. ENGINEERING CO., Ltd., and TAYLOR, J. C. Oct. 3, 1947, No. 26721. [Class 125(ii)] In a machine for successively filling a number of bottles 39 from a rotating reservoir 10 with which the bottle support rotates synchronously, each of a corresponding number of rollers 23 moves on and along and then off a fixed cam member 24 to reciprocate a spring- loaded hollow plunger 17 which raises and lowers a boss 27 thus contracting and extending a waisted rubber sleeve 30 secured to the boss and an outlet pipe 13, and to .cause the port 33 of a resilient valve member 12 to close, and then, to open as the member engages a bottle rim. An air tube 35 extends from the valve head 34 into the reservoir. The outlet conduit may be in the form of a telescopic tube.

Title: Improvements in bi-metallic thermal switches
IPC: H01H71/74
Filed: 1932-09-27
Abstract: 389,404. Thermal switches. ENGLISH ELECTRIC CO., Ltd., 28, Kingsway, London, and SCARF, C. T., Woodcroft, Rednal, Worcestershire. Sept. 27, 1932, No. 26814. [Class 38 (v).] In a thermal overload switch, a bimetallic strip 6, heated by a heating coil 5, bends downwards when a predetermined temperature is reached so that its contact stud 6a moves out of engagement with a conducting strip 9 which has previously been moved into a predetermined position by rotation of a cam 11. In order that the device will operate accurately a pair of holes 1b are provided in side walls of the casing and the bimetallic strip is bent or otherwise adjusted so that its free end is in line with these holes when the strip is cool and free from engagement by the strip 9. The strip 9 is freed for this purpose by rotating the cam 11 by means of a handle 14 when the strip 9 moves upwards of its own resiliency, the handle being first moved axially against a spring 13 to bring a projection on the handle clear of two stops between which it normally moves. The cam is then moved back to a predetermined position, the strip 6 being bent down more or less in the process. The heating coil 5 is in the form of a detachable cartridge which may be readily removed from its position between terminals 3, 4, by unscrewing the member 4 by means of a cap 4a. Heating coils of different sizes may then be substituted.

Class 142(2) In a double-lift dobby having a paper pattern 1, and which can be turned backwards for pick finding, only two sets of feeler needles, 3, 4 are provided, the arrangement being such that on one revolution of the loom the needles read two consecutive odd picks and, on the next revolution, two consecutive even picks. Preferably, the pattern perforations for the odd picks are displaced with respect to those for the even picks and the lower ends of the needles pass through a guide 5 which is moved sideways between each reading to read alternately the even and odd picks. The two rows 3, 4 of needles read perforations in the pattern 1, the needles being raised and lowered by a bar 8. Those needles which engage a hole in the pattern 1 lower members 9 and projections 10 thereon are engaged by either a pick finding knife 11 or a control knife 12 depending upon whether the loom is turning forwards or backwards. The knives 11, 12 are reciprocated in the direction of arrows E, D by cams. Movement of the knives 11. 12 is thereby transmitted via levers 16 and needles 18 to the hooks 20 of the dobby.

Title: Method and apparatus for driving an open-end spinning frame
IPC: D01H1/30
Filed: 1971-04-19
Abstract: 1343934 Driving open-end spinning frames TOYODA JIDOSHOKKI SEISAKUSHO KK and TOYOTO CHUO KENKYUSHO KK 19 April 1971 [18 April 1970] 27074/71 Heading DID [Also in Division G3] In an open-end spinning frame the rotors 3 are driven directly by the shafts of individual variable speed motors 11. The motors 11 may be connected to a high or low frequency power source to give a high normal running speed or a low running speed for piecing up. The low frequency is increasable to accelerate the rotor to normal running speed after piecing up. The low frequency source is carried by a carrier which traverses in front of the spinning frame until it detects an ends down whereupon it stops and connects the motor 11 to the low frequency source. Separate motors 10 and 12 may drive the feed and delivery rollers each being connected to the said electric sources, Fig. 1. Alternatively a single motor 106 mounted in the carrier may drive the feed and delivery rollers by mechanical engagement through clutches 96 and 97 respectively, Fig. 5. During normal spinning the feed and delivery rollers are driven by lay shafts 92 and 93. The carrier may carry a motor driven generator as the low frequency source or may act as a moving terminal for a fixed source. The electric sources may alternatively by solid state static inverters suitable circuits for which are illustrated in Figs. 3A and 3B, (not shown). If three separate electric sources 50, 60, 70 are employed for the feed, rotor and delivery respectively the rotating elements are synchronized by the circuit of Fig. 4. Motors 51, 61, 71 drive generators 53, 62, 73 whose outputs drive motors 54, 63, 74 driving generators 55, 64, 75 whose outputs are amplified and whose differential is used to operate motors 52a, 72a to vary the transmission ratio between motors 51, 71 and generators 53, 73 and hence maintains a constant ratio between the output of generators 53, 62 and 73. The carrier may also comprise means to perform the piecing up. Specification 1342658 is referred to (For Figures see next page)

Abstract: 797,398. Transistor multivibrator circuits. GENERAL ELECTRIC CO., Ltd., and JACKETS, A. E. Sept. 27, 1956 [Sept. 27, 1955], No. 27556/55. Class 40 (6). In a junction transistor multivibrator of the type shown the components are related by the following expressions where K is the ratio between the voltages at terminals 9 and 6 and A 1  and A 2  are the average values of the gain of transistors 1 and 2, respectively. By making the time constant C 10  R 7  greater than C 11  R 8  a steeper rise in output voltage is obtained at the collector of transistor 1 at the expense of that at the collector of transistor 2. Satisfaction of the other relations ensures that the transistors are " bottomed " during their " on " period and that the collector voltage approaches closely to the supply voltage during the " off " period.
