A cellulose acetate filter 27 may also be provided. In the embodiment shown one end 21a of a cigarette 21 is completely closed by the barrier 26a, perforations 24 in the cigarette wrapper 23 allowing smoke from the cigarette 21 to pass into the passageway 33, but in other embodiments the barrier is of smaller diameter than the end of the cigarette rod to allow smoke to be discharged axially therefrom and to pass thence, either via further perforations in the inner sleeve or directly, into the first smoke passage. The barrier 26a and body 26b are formed as a single solid plug. Various other forms of plug, including plugs with longitudinal grooves along part of their length, and different means for spacing the inner and outer sleeves, are also disclosed.

Title: Sound responsive device
IPC: G09B19/04
Filed: 1970-06-30
Abstract: 1279335 Controlling lamp by sound; deaf teaching aids NOVAR ELECTRONICS CORP 30 June 1970 [7 July 1969] 31749/70 Heading G4F and G5G A lamp 12 controlled by speech or other sound signals received by a microphone 17 is connected in a series circuit including terminals 9, 10 connected to an A.C. source, a normallyclosed switch 11 and an SCR 13. During each half cycle that the SCR is forward biased the SCR will conduct for at least part of that half cycle to illuminate the lamp 12 providing the audio frequency trigger signal supplied to the gate 14 from the microphone, has sufficient amplitude. The required amplitude is adjustable by a potentiometer 30 associated with the second stage 22 of a three stage audio amplifier 18, the output of the third stage 34 being connected through a capacitor 48 to the gate 14. The switching action of the SCR by the amplified audio signal causes the lamp 12 to flicker or to have extended "on" and "off" periods and thereby give some indication as to the nature of the speech. Thus the system may be used to teach deaf persons to speak or songbirds to sing. A rectified power supply circuit 51 is connected to the A.C. source 9, 10 in parallel with the SCR 13 and is thus driven by the A.C. source during those half cycles when the SCR is not forward biased, the circuit 51 serving to provide the amplifier 18 with biasing and power supplies. In a modification (Fig. 3, not shown) the SCR is replaced by a Triac.

Title: Valves having a seal assembly
IPC: F16K1/42
Filed: 1975-07-31
Abstract: A tight shutoff valve seal is disclosed, wherein an easily deformable annular valve seal member is retained within an annular groove in a valve element. Protecting this seal member from erosion or damage by a fluid flowing therepast is a slidable seal retaining member which additionally retains the seal member within the groove. The retaining member is resiliently urged to a seal-protecting position when a valve employing this seal is opened, and when the valve is closed the retaining member slides on a surface of the seal member and on a surface of the valve element to allow the seal member to abut and seal against a valve seating surface.

Abstract: 734,301. Gas turbine plant. BENDIX AVIATION CORPORATION. Jan. 23, 1953 [March 22, 1952], No. 2057/53. Class 110 (3). [Also in Groups XXVIII and XXIX] The supply of liquid fuel to a jet propulsion or other gas turbine engine is regulated by a throttle 58 the pressure drop across which acts on a spring-loaded diaphragm 61 actuating a control valve 60 which in turn regulates the period of time the delivery valves 28 of a swash-plate pump 10 (see Group XXVIII) supplying the engine are open during the suction stroke of the pump. The valves 28 are loaded by springs 41 and chambers 40 at the rear of the valves communicate with the pump delivery pressure by restricted orifices 24 in the valves themselves or by a bleed connection between the delivery chamber 37 and an annular manifold 44 connected to the chambers 40 by ports 43. The manifold 44 is connected by a conduit 45 to the valve 60 which is itself connected to the low-pressure side of the pump by a conduit 71. The pressure drop across the valve 60 is regulated by a further valve 72  actuated by a spring-loaded diaphragm 73. The valve 72 comprises a hollow sliding member with ports 70. The passage 45 is connected to a chamber 74 on one side of the diaphragm 73 by a passage 75 having a calibrated restriction 751. This arrangement limits the rate .of response of the valve 72 and serves to prevent surges in the main delivery pipe 39.

Title: Improvements in or relating to the production of dried vegetable juices
Inventor: OWTRAM GODFREY HERBERT
IPC: C13B30/02
Filed: 1961-09-08
Abstract: Dry preparations of vegetable juices, e.g. juices of sugar cane, sugar beet, carrots, are made by concentrating the juice to a treacle-like consistency, dispersing a dry powder exemplified by maize, tapioca or potato starch, tricalcium phosphate, kaolin, talc, calcium carbonate and magnesium carbonate throughout the concentrate, and then drying the mixture.  The juice may be neutralized by adding calcium hydroxide before concentrating.  An example is of making a product having 86% of total sugar, including 4% of reducing sugar, 1% of protein, 3.5% of ash, 5% of starch and 3% of moisture by filtering raw juice of crushed sugar cane, concentrating the juice in a vacuum evaporator to 85-90 degrees Brix, stirring in appropriate quantities of starch and the dry product of a previous batch, and feeding the mixture to a drum dryer.  The procedure is suitable for making animal feed from sugar cane juice, the sugar which crystallizes out in the initial concentrating being removed for human consumption.
