Title: Improvements in letter controlled mechanism
IPC: B41K3/64
Filed: 1944-05-05
Abstract: 576,267. Printing- machines; feeding sheets. PITNEY - BOWES POSTAGE METER CO. May 5, 1944, No. 8569. Convention date, March 12, 1943. [Classes 100 (i) and 100 (ii)] In a machine for printing postage marks on letters by means of a rotary printing-cylinder 13 which is operated by power or by a hand crank 10 and helical gears 11, 12, rotation of the printing-cylinder is prevented by a trip member 17 which is controlled by means actuated by the letter L in such manner that the trip member prevents actuation of the printing cylinder until the letter engages a registering stop 54 and so is in correct position to receive an impression. On insertion of the letter L it acts upon a pivoted member 46 which transmits motion via a lever 49, link 51 and lever 45 to a lever 41 provided with an arm 43 which is moved into the path of a rod 35 to obstruct its movement. This rod is connected by a pin-and-slot connection to a lever operated by a lever 27 by means of which the trip member 17 is operated to release the drive. The drive cannot take place therefore until the lever 41 is actuated to move the arm 43 out of obstructing position, This is effected by the action of the letter or the stop 54 and consequent counterclockwise movement of a lever 58 on the shaft 55 of the stop. The shaft 55 transmits motion 'via a lever 64 to a lever 66 fitted with a pin 68 which engages the arm 44 of lever 41 and moves the arm 43 clockwise out of obstructing position. The movement of the lever 58 is limited by engagement of a pin 63 with the end 71 of a spring-controlled lever 72, from which it is released by the action of a cam 74 driven from the printing-cylinder. A further cam 81, which is of flanged shell formation with a break 83, Fig. 5, not shown, in the flange, acts upon the pin 63 on lever 58 to depress the stop 54 to allow the letter to advance, and subsequently to return the stop to the position of Fig. 1. To prevent accidental operation of the obstructing device, a feeler 91 is arranged in the path of the letter and operates to release a latch lever 88 which normally engages a latch collar to prevent motion of the shaft 55, which can thus only be operated when a letter has passed the feeler 91.

Title: Conveyor belt apparatus
IPC: B65G45/12
Filed: 1978-03-06
Abstract: Each of the scrapers to be arranged at two discharge ends of a reversible belt band (3) has a support (8) which holds a plurality of scraper elements resting under spring pressure against the underside (4') of the belt band. Each scraper element consists of a cutting piece (21) and a spring apparatus (17, 18, 19) which acts in two directions and has a pivot mounting about an axis (A) for the cutting piece (21). In its operating position, the support (8) is so arranged relative to the underside (4') of the belt band that the distance (h) of the axis (A) from the underside (4') of the belt band is shorter than the connection between a cutting edge (23) of the cutting piece (21), resting against the underside (4') of the belt band, and the axis (A). The spring apparatus (17, 18, 19) permits the cutting edge to make contact in each case at a short distance (a) before or behind the bottom point of the perpendicular dropped from the axis (A) onto the underside (4') of the belt band, depending on the direction of movement of the belt band (3). As a result, a high, constant scraping performance, with the gentlest possible treatment of the belt band, and a simple change-over of the scrapers from the active to the inactive position and vice versa can be achieved. <IMAGE>

Patent GB-706562-A (GB)
Title: Method of reconstructing glyceride oils
Inventor: BARSKY GEORGE
IPC: C11C3/08
Filed: 1951-04-17
Abstract: Glyceride oils of the coconut oil group are reconstructed by heating them with free fatty acids containing only 12 to 18 carbon atoms, under such conditions that these added fatty acids displace those fatty acids of the glyceride which contain 6 to 10 carbon atoms, and the vaporized fatty acids are fractionated so as to remove the displaced fatty acids and return the others to the reaction zone. The free fatty acids added may be obtained by partial hydrolysis of the oil to be reconstructed, by heating at reduced pressure and under reflux so that only the fatty acids of 6 to 10 carbon atoms are removed and under conditions such that reconstruction does not take place.  The reconstruction is then carried out at an increased temperature and with further reduction of pressure.  A zinc oxide or boric acid catalyst may be used for the reconstruction, and steam may be passed through the mixture during the reaction to assist in the vaporization of the fatty acids.  The reconstructed glyceride may be purified by a final step of steam distillation.  In an example, 40,000 parts of coconut oil are mixed with 14,400 parts of palm oil fatty acids and 180 parts of boric acid, and heated under vacuum with continual agitation at about 260 DEG C.  The product was steam distilled to reduce the free fatty acid number to 4. Specifications 571,209 and 700,376 are referred to.

Abstract: 535,927. Telegraphones. ELECTRICAL RESEARCH PRODUCTS, Inc. May 21, 1940, No. 9003. Convention date, July 29, 1939. [Class 40 (ii)] In making a telegraphone record, the record strip 1 is first subjected by pole pieces 2 to an erasing alternating magnetic flux of frequency higher than any to be recorded and then by other pole pieces 3, to the recording magnetic flux accompanied by an alternating magnetic flux of higher frequency than the erasing flux but of lower intensity. As shown, the. alternating fluxes are produced by alternating currents derived from a single thermionic oscillator 7 rich in harmonics. The fundamental frequency of this oscillator is fed through a condenser 10 to the coil 9 of the pole pieces 2, the condenser and the coil being tuned to accept this frequency. The third harmonic is supplied to the coil 15 of the pole pieces 3 through a condenser 17, an,adjustable resistance 16, the coil and the condenser being tuned to accept this harmonic, and a coil 22 and condenser 23 tuned to the fundamental being interposed between the oscillator and the condenser 17 to choke off the fundamental. These devices can be connected for recording or reproducing by means of a switch 4. In the recording position, power from source 5 is fed through choke 24 to oscillator 7, and microphone 11 is connected through amplifier 12 to coil 15. In the reproducing position of the switch 4, the microphone and the oscillator 7 are cut off, and the coil 15 is connected through equalizing circuit 18 to amplifier 12, the output of which is then connected to a loudspeaker 19.
