Patent GB-724607-A (GB)
Title: Bulb loading apparatus
IPC: B65G47/14
Filed: 1953-05-22
Abstract: 724,607. Making electric lamps. SYLVANIA ELECTRIC PRODUCTS, Inc. May 22, 1953 [May 24, 1952], No. 14539/53. Class 39 (2). Apparatus for feeding the bulbs or envelopes of electric lamps and similar devices automatically to the holding heads of a sealing machine comprises a bulb transfer head which is arranged to bring a bulb to a position above and in register with a holding head of the sealing machine and is reciprocable vertically towards and away from the said holding head, whereby a cam follower device mounted on the transfer head is engaged by a cam mounted adjacent to its path of reciprocation, causing the transfer head to pivot upon a block on which it is mounted and guide the neck and cullet of a bulb laterally past the holding head to permit the said head to receive and engage the bulb itself. The invention is particularly applicable to bulbs in which the cullet at the free end of the bulb is of greater diameter than the bulb itself. In the example bulbs 90 are loaded on to a rotary turret 22 which is indexed in a clockwise direction in synchronism with an adjacent sealing machine 10 rotating anti-clockwise, the turret 22 being also arranged to be reciprocated in a horizontal plane, upon guide bars 28, from the position indicated in broken lines to that, shown in full lines. When in the latter position a bulb 90 held in work-holder 23 of turret 22 is between, and in register with, a bulb holder 18 of the sealing machine and the bulb transfer head 74, Fig. 2. The bulb transfer head 74 is next moved downward into contact with the top of the bulb 90 and then moved upward with the bulb held therein by suction, this movement being effected by a barrel cam 64 acting upon a rocking lever 54 linked to a vertical rod 42 which is slidable within guide brackets 46 and supports a lateral arm 40 carrying a hollow rod 44 with the transfer head 74 on its lower end. Immediately after the transfer head 74 has lifted the bulb from the turret 22 that turret is retracted and at the same time is indexed through one step to bring another bulb into the transferring position. The shaft 42, with the bulb held in the transfer head 74, is also moved downwardly so that a cam follower roller 78, Fig. 4, mounted on the transfer head moves down within an irregular channel 88 formed in stationary cam 38 which is mounted on fixed bracket 34, so that the suction head is swung about a pivot pin 76 on its mounting block and displaces the bulb 90 sufficiently to bring the cullet 91 out of register with the bulbholding fingers 20 of the work-holder 18 of the sealing-head. The bulb continues to move down in a canted position until the cullet 91 has passed the bulb-holding fingers 20, whereupon the changing contour of the channel 88 returns the transfer head 74 to the vertical position, and at the completion of the downward stroke the bulb is seated on the fingers 20. The vacuum line is interrupted momentarily to release the bulb from the transfer head and the latter returns to its starting position.

Patent GB-681994-A (GB)
Title: Improvements in or relating to the production of cellulose
Inventor: BATE STANLEY CHARLES
IPC: D21C3/00
Filed: 1949-05-31
Abstract: Cellulose is obtained from lignin-containing cellulosic material by heating the material with an alpha - hydroxy - carboxylic acid (or dehydrated derivative thereof) in the liquid phase.  The cellulosic material may be spruce, larch, fir, poplar, or beech-wood, or straw from cereal plants.  Glycollic, lactic, malic, tartaric, citric, a -hydroxy-butyric or isobutyric, or a -hydroxycaprylic acid may be used.  The hydroxycarboxylic acid may be used alone or diluted or mixed with another compound, e.g. water, acetic acid or other carboxylic acid containing not more than 4 carbon atoms, ethyl valerate, ethyl chloracetate, amyl alcohol, ethylene glycol or di- or tri-ethylene glycol.  The alpha-hydroxy-carboxylic acid is preferably used in a concentration of 25-85 per cent by weight of the liquid mixture. The temperature may be 110-170 DEG  C. and the duration of the treatment may be 3-10 hours for deciduous woods and up to 24 hours for coniferous woods.  The cellulose is washed after the treatment and may then be further purified by treatment with chlorites or hypochlorites or with caustic soda solutions.  Cereal straws may be given a preliminary open boil with dilute hydrochloric or sulphuric acid and also with dilute caustic soda. The hydroxy carboxylic acid may be recovered for re-use.  Thus, a used liquor containing glycollic acid and acetic acid is diluted with water to precipitate the lignin which, after agglomeration by heating, is removed by filtration or decantation.  The acids are then distilled till all the water has been removed and at least part of the acetic acid.  The acetic acid in the distillate may be concentrated by extraction with a mixture of ethyl acetate and benzene.  The residue comprising glycollic acid with or without acetic acid may be used again in the process.  Specifications 640,490 and 679,832 are referred to.

Title: Improvements in and relating to turnstiles and similar gates and to coin release mechanism for use therewith
IPC: G07F17/14
Filed: 1952-06-13
Abstract: 728,066. Coin-freed turnstiles. BRECKNELL, MUNRO & ROGERS, Ltd., and DOLMAN, H.J. June 15, 1953 [June 13, 1952], No. 14939/52. Class 27. A turnstile has coin-released mechanism which is mounted on a fixed structure 3 and comprises a latch 1 pivoted on a shaft 2 and engaging a strut 6 between the outer ends of the upper and lower armsof the turnstile and a pawl 9 pivoted on a shaft 8 carried by the latch 1 and co-operating with a fixed stop number 16. The fixed structure may form the barrier between two turnstiles and the release mechanism may be operated by a three-penny piece or three pennies or by a sixpence; if adapted for use with sixpences, the other two coin slots are blanked off and vice versa. The latch 1 is normally urged by a spring-loaded rod 12 so that its surface 5a engages the strut 6 and the initial movement of the turnstile willrotate the latch so that the tooth 9a of the pawl is moved against a stepped face 16a of the stop member and prevents further rotation. If, however, there is a sixpence in the slot 33 or a threepenny piece in the slot 19, the stationary coin will engage a lever 36 on the pawl shaft 8 or the tail 9b of the pawl, respectively, so that the pawl is rocked out of engagement with the face 16a and allows the latch to be rotated out of the path of the strut 6; three pennies 28 will also rock the pawl, their weight acting on a lever 23 causing a trip lever 22 to be placed in the path of a second lever 20 on the pawl shaft 8. The sixpence and three-penny piece are released into a coin box when support plates 34 and 17 on the latch are' moved from beneath them and the three pennies fall clear of a guide 29 when a plate 32 on the latch moves from beneath the trip lever 22. Stop lugs 37, 38 limit the movement of the latch and a spring-loaded detent 40 and ratchet 41 ensure that the latch moves sufficiently each time to allow the coins to pass to the coin box.
