Filed: 1928-05-17
Abstract: 295,009. Sulzer FrÞres Soc. Anon. Aug. 6, 1927, [Convention date]. Refrigerating, absorption machines for.-The heating- means for the generatorabsorber 1 of a reversing system is arranged to prevent accumulation of gas bubbles on the hot surfaces and the resultant local overheating and dissociation of the gas. To this end the heating elements, for example electric heating cartridges, are located in elongated chambers 11, 12 closely surrounded by sleeves 15, 16 having apertures 17 at their lower ends and open at the top. The liquor rises in the annular space in each sleeve and carries away gas bubbles.

Title: Improvements in or relating to pump-operating mechanism for individual-type casting machines
Inventor: MELDRUM EDWARD CHARLES
IPC: B41B7/04
Filed: 1953-05-26
Abstract: 722,691. Type-casting machines. MONOTYPE CORPORATION, Ltd. May 26; 1953, No. 14594/53. Class 100 (3). Metal pumps.-Relates to pump-operating mechanism for an individual-type casting machine comprising two levers linked together intermediate their ends and coupled respectively one to the pump body and the other to the pump piston, the levers being moved in unison and then relatively to each other to operate the piston. Spring-operated pump elevating levers are provided to seat the nozzle in the mould, and a detent acts thereon to interrupt temporarily the seating of the nozzle, so that on release of the detent at a predetermined time, the pump elevating levers are given an accelerated movement by their operating spring to seat the nozzle in the mould. In a machine of the general construction described in Specification 21014/07, [Class 100], the rise of the pump-elevating lever N‹ when the stud N<SP>8</SP> is raised by the driving cam is delayed by a detent N<SP>18</SP> carried on a cranked lever N<SP>14</SP>, N<SP>15</SP>. When the detent is released, the pump-elevating spring N<SP>7</SP> causes an accelerated movement of the nozzle to ensure proper seating in the mould. The lever arm N<SP>15</SP> is pivoted to a slide N<SP>21</SP> balanced in the position shown by opposed springs N<SP>26</SP>, N<SP>30</SP>. The slide carries an adjustable abutment N<SP>39</SP>, held in its adjusted position by a detent N<SP>42</SP>, which at a predetermined point in the machine cycle is engaged by rising abutments P<SP>17</SP> so as to, raise the slide and release the lever N‹. The abutments P<SP>17</SP> are attached to the driving-rod and are utilized also to release the latch for operating the pump piston as described in Specification 21014/07, [Class 100]. The abutments P<SP>17</SP> comprise a plurality of leaves secured by a winged screw P<SP>18</SP> and individually pivotable out of position beneath the latch arm P<SP>16</SP> so as to vary the force applied to the piston. When the slide is allowed to fall, the detent N<SP>18</SP> rests against the end of the lever N<SP>9</SP> until the latter is depressed by the stud N<SP>8</SP> and the detent moves into locking position. When the slide N<SP>21</SP> is in its upper position, it can be retained there by a catch N<SP>34</SP> so as to hold the delay mechanism out of operation.

Abstract: 550,119. PIanmg-maehines. RICHARDS & CO., Ltd., G., and ARDERN, S. O. Nov. 13, 1941, No. 14627. [Class 83 (iii)] A power-operated feed mechanism for a planing or like machine comprises two electric motors, controlled from the table movement, one of the motors actuating the feed and the second being arranged to reset a feed-determining slide operated by the first motor. The feed motor a, which is started by the operation of the tablecontrolled master switch of the main motor, drives a shaft b connected by a two-speed gear pair c. d to a shaft g driving the tool box or boxes, (not shown), the feed movement occurring at the end of the return table movement before the tool engages the work. A gear h on shaft b drives through a gear i and clutch k, a shaft j which, through worm gearing n, drives the wheel p of a differential gear connected through a gear r with the feed-determining rack slide s. This slide carries a striker t adapted to open a switch v carried by an adjustable rack w which can be set by a hand-wheel 2. If the rack s should over-run, a striker y thereon operates a safety switch x on the rack to disconnect motor a. The rack is reset after its traverse by a motor 7 which is started by the actuation of the master switch at the end of the cutting stroke. The motor 7 through worm gearing 8 drives the planet carrier 9 of the differential gearing. The striker 11 actuates switch 12 to cut out the resetting motor. If the rack s over-runs on this movement a safety switch 14 is operated. For rapid traverse of the feed boxes the clutch i is disengaged and the motor a run in either direction without traversing the rack slide s.
