Title: Marmalade base and process for its preparation
Inventor: SPROSS SPENCER ASA
IPC: A23L21/12
Filed: 1960-03-23
Abstract: In marmalade base manufacture the citrus fruit, e.g. oranges, is peeled and the peel and peeled fruit fractions processed separately. The peel is mechanically shredded, heated to 200 DEG  F. to inactivate the pectin esterase, tenderised by heating to 190 DEG  F. to 205 DEG  F. with aqueous citric acid solution of pH 3.7 to 4, canned at 200 DEG  to 205 DEG  F., cooled and stored at 40 DEG  F. The peeled fruit is continuously extracted with water to provide a fruit solid concentrate of 8 degrees to 10 degrees brix which is stabilized by heating to 205 DEG  F., cooled to 100 DEG  F. to 150 DEG  F. and depectinized at 100 DEG  F. to 140 DEG  F. with pectin-esterase; clarification is then effected, e.g. by filtration and/or centifrugation, and all enzyme activity destroyed by heating, e.g. to 212 DEG  F. for 1 minute.  The liquid is then concentrated to 21 degrees, 42 degrees or 80 degrees brix depending on whether a liquid, paste or dehydrated powdered base is to be prepared; for a liquid or paste, citrus pectin in amount equivalent to that removed is added together with a small amount of citric acid and sodium bicarbonate, these additives being mechanically dispersed in the concentrates which may then be frozen to 0 DEG  F.  The 80 degrees brix concentrate is further dehydrated in vacuo to a moisture content of 1 1/2 to 3% before the same such additions are made and the resultant powdered mix is sealed in containers.  To produce marmalade both peel and fruit concentrate fractions are combined, and water, sugar and citric acid being added.

Abstract: 610,450. Radionavigation. SOC. INDUSTRIELLE DES PROCEDES LOTH. April 5, 1946, No. 10608. Convention date, Jan. 18, 1941. Drawings to Specification. [Class 40 (vii)] A radio beacon for the instrument landing of aircraft comprises means for alternately transmitting vertically polarized complementary signals having overlapping directional characteristics to define a course line, and means for radiating on the same frequency a differently modulated signal which is horizontally polarized so as to be substantially unaffected by variations in the conditions of the earth's surface to define a glide path of constant field intensity. Signals of carrier frequency F are generated by a transmitter and are applied to modulators whence are derived side-band signals having frequencies FŒf1, FŒf2. The side-bands FŒf1, together with the carrier frequency are used for the vertically polarized overlapping beam system, while the side-bands of frequency FŒf2 are radiated with horizontal polarization so that together with the vertically polarized carrier wave signal they define a glide path substantially independent of variations in the reflection coefficient of the surface of the earth.

Abstract: 1461984 Electronic timepieces SUWA SEIKOSHA KK 14 March 1975 [27 March 1974] 10715/75 Heading G3T In a battery powered electronic timepiece having a stepping motor driving hands via gears, the seconds hand is normally indexed one step each second, but when the battery voltage is lower than a value VTH the seconds hand is indexed by two steps in quick succession after each two second interval to indicate the state of the battery. The timepiece, Fig. 1, comprises a crystal controlled oscillator circuit followed by a binary frequency divider chain of D-type flip-flops. FF 1  - - FF n . The output of stage FFK is at a frequency of ¢HZ and is fed to flip-flops FF (n   +   1) , FF (n   +   2)  which produce a delayed output signal. When battery B voltage is above a threshold value VTH determined by a zener diode D and a transistor T, the transistor conducts and its collector potential P goes relatively low. When the battery voltage is below VTH the base current of transistor T ceases and P goes high. Gate circuitry including inverters I 3 , I 4 , I 5 , and gates O 1 , O 2 , A 1 , A 2 , A3 produce drive signals from the outputs of FF n , FF n   + 1 , FF n   + 2 , under control of potential P. The drive signals from I 5  and A3 are shown by waveforms q and r respectively, Fig. 2, the left hand portions of the waveforms being when the battery voltage is above VTH and the right hand portion when it is below VTH. These drive signals are amplified to normally produce alternately positive and negative current pulses through motor winding L - one pulse each second as in the left hand portion of waveform i Fig. 2. The rotor will be rotated 60 degrees by each pulse. When the battery voltage is below VTH and P is high the motor current consists of a positive pulse and immediately succeeding negative pulse occurring every two seconds as in the right hand portion of waveform i. The rotor will be rotated through 120 degrees every 2 seconds and the seconds hand indexed two steps each 2 seconds. The correct time will be indicated but the abnormal action of the seconds hand indicates that the useful life of the battery is ending.

An apparatus for beading or simultaneously flanging both ends of metal cylinders, e.g. can bodies, comprises beading and flanging tools 9 circularly orbiting about a central beading and flanging cylinder 19 which is arranged for rotation eccentrically to the circular orbit of the beading tools 9 by a rockable, resiliently supported bearing 20. A can body is conveyed by a worm feed 35 between opposed beading tools 9 mounted on beading mandrels 8 which are rotated about their own axes by a driving wheel 6, keyed on a rotating tubular shaft 3, engaging pinions 7 mounted in a member 14. The tubular shaft 3 is rotated about a fixed central shaft 2 through a pinion 4 and wheel 5, and through arms 17 rotates a ring 18 on which the beading cylinder 19 is mounted. The beading mandrels 8 are mounted in the member 14 which is rotated by a driving wheel 16 to move the beading tools 9 in a circular orbit. The opposed beading tools 9 are displaced axially into the can interior by a roller 11 engaging in a stationary cam 12. As the beading tools 9 are moved in their circular path, they approach the eccentrically rotating beading cylinder 19 to cause the can to be deformed, springs 29 producing a buffer effect. After deformation, the beading tools 9 are retracted by the cam 12 and the can conveyed by a deflector 37 into a channel 38. The can ends may be simultaneously flanged by co-operating flanging surfaces 9a, 19a on the tools 9 and cylinder 19. The bearing 20 is rockably mounted on a fixed carrier 21 by a bolt 22, and eccentrically positions the beading cylinder 19 by adjusting wedge-shaped bars 23, 24.

Abstract: 1418797 Rotary internal combustion engines M KAMIYA 6 March 1973 10853/73 Heading F1F A rotary internal combustion engine comprises intersecting toroidal cavities 7, 8 around which pistons 5, 6 move in a continuous circular motion. Each cavity 7, 8 has suction and exhaust ports 11, 14 and 12, 15 respectively each controlled by a rotary disc valve fixed to the shaft 3 or 4 with which the respective piston rotates. The cavities 7, 8 also have respective compressed gas ports 18, 19 connected to combustion chambers 17, 16 in the opposite cavity by passages 31, 31', Fig. 4. In operation, beginning from the position of 6a, it can be seen that piston 6 has just thrust compressed fuel/air mixture to combustion chamber 16 via compressed gas port 19. At the same time, piston 5 is compressing gas in the chamber communicating with its leading end B. The charge is ignited in chamber 16 and the piston 5 is driven and its front end B thrusts compressed charge to the other combustion chamber 17, Fig. 6b, whilst piston 6 inducts air through suction port 12 and also exhausts the products of the previous combustion through exhaust port 15. The charge in chamber 17 is then ignited and piston 6 is driven whilst its front end B' compresses the previously inducted charge, Fig. 6c, the piston 5 meanwhile discharging its combustion products through port 14 while taking in a fresh charge through port 9. Eventually the situation of Fig. 6d is reached where piston 6 is just about to finish compression of charge into combustion chamber 16 for ignition in the position of Fig. 6a.
