Title: Improvements in or relating to the mechanical handling of eggs
Inventor: EATON TIMOTHY ALFRED REID
IPC: A01K43/00
Filed: 1959-02-27
Abstract: 875,175. Holding and picking-up eggs. EATON Ltd., TIMOTHY, and THORNBER BROS. Ltd. Feb. 17, 1960 [Feb. 27, 1959], No. 6828/59. Class 61. Apparatus for lifting and transferring eggs from a packing tray to a hatchery tray comprises a group of suction heads mounted at the underside of a body and equal in number to the full egg complement of the packing tray, means whereby suction can be applied or cut off from the heads collectively to grip or release a tray load of eggs and means whereby the relative positions of the heads can be instantly changed to suit either the spaced egg arrangement of the packing tray or the mutually contacting arrangement in which the eggs require disposition in the hatchery tray. As shown a number of carrier members 14, 18, mounted parallel to one another at the underside of a rectangular plate 10, are provided with equal numbers of rubber suction heads 32 disposed at equal intervals and in a single longitudinal row on each carrier member. The carrier members comprise flat section tubes 14, 18 slidable in a direction transverse to their lengths on guide bars 11 which are fixed to dependent end brackets 12, 13 on the plate 10. The alternate carriers 18 are also capable of endwise movement relative to the carriers 14 under the influence of lazy tongs linkages 22, 23 connecting consecutive carriers in such manner that displacement of any of the carriers 14 will cause collective lateral movement of all the carriers and a relative endwise movement of the carriers 18. The collective sliding movement of the carriers is effected by links 28 connecting two of the carriers 14 to opposite arms of a rocking lever 26 mounted on the plate 10 and carrying a handle 30. The tubes 14, 18 communicate with the associated row of suction cups, the tubes being closed at one end and connected at the other end by flexible piping to a header 34 mounted on the plate 10. The plate 10 is provided with a lifting handle 35 of inverted U-shape one arm of which is connected to the header 34 by a flexible pipe. The other arm of the handle 35 is provided with a valve which is manually operated by a knob 43 whereby suction supplied through a flexible piping can be applied or shut off from the cups. In a modification the relative endwise movement of the rows of suction cups is effected by a double acting piston in a cylinder mounted beneath the plate 10, air pressure being admitted to either end of such cylinder under the control of a manually operated valve in a second lifting handle on the plate 10.

Title: Improvements in and relating to Latches and the like.
Inventor: OTTINGER LEON
IPC: E05B55/04
Filed: 1916-05-25
Abstract: 103,064. Ottinger, L. May 25, 1916. Doors for passenger vehicles.-In a door latch which is automatically fastened upon closure of the door, the bolt 4 is actuated by a spring 9, which is contained in a cylinder 7 pivotally supported at 8, and bears on a plunger 6 having a nose-piece 19 adapted to bear, in some positions, on the rear of the member 4. The plunger 6 engages, by means of a pin 11, a slot 12 in a pivoted plate 10, which has noses 14, 15 adapted to engage respectively parts 17, 16 of the bolt and exert a pressure thereon to close or withdraw it, the direction of pressure depending on whether the line of thrust of the spring 9 is on one side or the other of the plate pivot 18. When the parts are in the position shown in Fig. 1, inward movement of the bolt by direct pressure thereon is prevented by the engagement of the part 13 of the plate 10 with the projection 17 of the bolt. An arm 22 engaging the cylinder 7 and turned by a handle 21, and an arm 28 mounted on a spindle 27 and engaging the projection 30 on the plate 10 are provided for operating the bolt. A key-operated arm 24 may be operated to lock the latch. In order to move the bolt into the engaging position when the door is closed, a pivoted sector 31 is provided, controlled by a spring 33 and adapted to engage a projection 32 on the plate 10. When the sector 31 is rotated owing to engagement with the socket plate 34 on the closing of the door, the plate 10 is rotated until the line of thrust of the spring is past the dead-centre, and the further action of the spring is to press the bolt into its socket. The end of the bolt is provided with a pivoted nose-piece 35 having a tail 36, which is pressed by the spring of the latch against the bolt casing, thus causing the nose to bear laterally against the socket. Ribs 38, 39 on the door and door casing are provided to act as guides to secure the correct alignment of the parts, for instance if the door has a tendency to sag.

Patent GB-697959-A (GB)
Title: Production of pentaerythritol
IPC: C07C31/24
Filed: 1950-03-24
Abstract: Pentaerythritol is made by mixing formaldehyde produced by the vapour phase partial oxidation of aliphatic hydrocarbons and containing traces of other oxygen-containing products of the oxidation, with acetaldehyde and an aqueous alkali, the temperature is allowed to rise to about 103-115 DEG  F. during the resulting exothermic reaction, the reaction is allowed to continue for a period during which the temperature falls, heat is then applied to initiate a further exothermic reaction and cooling is effected as soon as the said further reaction is complete, and the product is neutralized and penta-erythritol recovered therefrom. Preferably the second stage is effected at 2 to 15 DEG  F above the highest temperature previously obtained and this heat may be applied 15 to 30 minutes after the temperature has started to fall on completion of the first stage.  A calcium hydroxide slurry is most effective as the aqueous alkali and on neutralization with sulphuric acid the insoluble sulphate may be filtered off before isolation of pentaerythritol by crystallization after concentration of the solution by subatmospheric pressure. Preferably per molar proportion of acetaldehyde, 4.5 to 5.5 and 0.6 to 0.8 molar proportions of formaldehyde and calcium hydroxide are used respectively.  Preferably the amount of water used is such that the aldehyde content is 14 to 18 per cent.  In an example, a 36.7 per cent by weight aqueous solution of formaldehyde obtained via partial oxidation of propane or butane or mixtures thereof is mixed with two molar proportions of acetaldehyde and the mixture added rapidly to an aqueous slurry of calcium hydroxide to give on completion of the reaction after 45 mins. an aldehyde concentration of about 16 per cent, the initial temperature of about 70 DEG  F. rose to 107 DEG F., cooling being provided at 95 DEG  F., the mixture is allowed to stand for 15 minutes, the temperature dropping to about 98 DEG  F. and then heated to 107 DEG  F. during about 15 minutes, after which the second exothermic reaction starts, the temperature reaching about 115 DEG  F. and after the disappearance of the formaldehyde odour the mixture is cooled, neutralized with sulphuric acid, and pentaerythritol is isolated as above indicated.  The second stage may conveniently be followed by a polarograph to avoid over-condensation to di- and poly-pentaerythritol.  Specification 697,906 is referred to.
