Patent GB-779895-A (GB)
Title: Improvements in or relating to apparatus for applying adhevise to labels and fixing them to articles
IPC: D06H1/04
Filed: 1954-03-09
Abstract: 779,895. Labelling machines. BARRACLOUGH, Ltd., R. W., and BARRACLOUGH, R. W. May 2, 1955 [March 9, 1954], No. 6772/54. Class 73. Adhesive is applied to labels and the labels are applied to articles, such as packets of tea, by apparatus incorporating a label stacker 45, 46, means for applying adhesive to a plate 30 as it reciprocates from the position shown to a position beneath the stacker where it picks up a label, means for transferring the label from the plate to a transfer head 18 which reciprocates in the opposite direction to the plate from the label-transferring position shown to a position above the article, and means for transferring the label to the article. The apparatus shown is mounted on one side of the plate 10, and on the other side of the plate, Fig. 2 (not shown) are mounted the various cams and levers for moving the parts in the correct timed sequence. The plate 30 and head 18 are mounted on carriers 14; 13, respectively, which are caused to move in opposite directions by engaging on opposite sides of an oscillating toothed wheel 17. As the plate moves to the right adhesive is applied to it by a roller 37 which has received adhesive from a roller 36 rotating in a bath 35. Roller 37 is mounted on a cam-operated arm 38 and has teeth 40 which can engage with teeth on the roller 36 and also with a rack on the plate 30. When the plate reaches a position beneath the stacker the latter is lowered and the lowermost label adheres to the plate. When the parts return to the position shown the transfer head, which includes a vertically movable tube 20, connected at 21 to a source of suction, and a hollow shaft 19 riding at 24 on a rail 25, is lowered towards the plate by the anti-clockwise rotation of arms 27 which support the rail. Simultaneously -a cam-operated stripping rod is moved upwards towards.an aperture in the plate and pushes the protruding end 23 of the tube 20 upwards so that the label is held between the rod and a rubber block 22 of the head 18. The transfer head now begins its upward movement, followed by the stripping rod for a short distance until the label is removed from the plate. Suction applied to the tube 21 retains the label on the transfer head, the stripping rod is returned to its lower position, and the transfer head with the label held to the now protruding part 23 of the tube is moved to the left by the wheel 17. At the applying station the transfer head is again moved downwards to press the label on to the tea packet, suction being then cut off. The transfer head is then lifted and returned to the original position shown. The guides for the label stacker may be fitted with a bolt which is normally spring- urged away from the path of the stacker but which can be moved by a hand lever to retain the stacker in its upper position. This lever may be controlled by a switch which comes into operation when all the labels in the stacker have been used.

Abstract: 749,154. Machine-tool details. BECHLER, A. March 9, 1954 [March 12 1953], No. 6873/54. Class 83 (3). A machine tool having hydraulic feed means comprising a pump delivering liquid from a first tank and means for cooling the tool by a coolant liquid comprising a pump delivering liquid from a second tank, is characterised in that the same liquid is used both for feeding the machine slides and for cooling the tool, the first tank being connected to the second tank and means being provided for collecting the coolant liquid and leakage from the feed system and returning both lots to the second tank. As applied to a vertical-spindle milling machine, the work slide 1, Fig. 2, is moved by a piston and cylinder 2, 4, supplied with pressure through a line 9 from a pump 11, Fig. 3, and a first tank 12. The latter is submerged within a second tank 14 into which extends a pump 16 driven from the same spindle 27 as the pump 11. The pump 16 supplies coolant through the line 17 to the tool 18, Fig. 2. The tanks are interconnected through a filter 23. Waste liquid falls from the end of the work-table through a pipe 20 and collects in a tray 21 above the tanks, a filter plate 22 allowing liquid to drain back into the outer tank. The latter is extended across the machine base to provide a tray 24, Fig. 2, to collect drips from the hydraulic feed system. The housing for the pump 11, Fig. 3, and the driving spindle bush are made integral with the inner tank, the pump 16 being bolted beneath the pump 11.
Patent GB-572752-A (GB)
Title: A process for the preparation of ª€-valerolactone
Filed: 1944-04-14
Abstract: d -Valerolactone is prepared by reacting d -hydroxy valeric aldehyde or its isomer epoxy 1-5 pentanol-5 with oxygen at superatmospheric temperature.  Oxidation catalysts such as the oxides and salts of metals other than copper, having more than one valency state may be present, for example, cerium, cobalt, lead, manganese and chromium. When the reaction is carried out in the liquid phase, the catalyst selected should be soluble in the reaction mixture; the acetates, stearates, oleates and naphthenates of the abovementioned metals are salts soluble to an adequate extent.  The reaction may be carried out in the presence of solvents such as acetic acid which are not oxidized under the reaction conditions.  In the absence of a catalyst, the reaction proceeds at a reasonable rate at 90 DEG  to 100 DEG  C., but is slow below 80 DEG  C.  In examples: (1) air is bubbled through dry d -hydroxy valeric acid aldehyde at 100 DEG  C. with stirring to form the lactone; (2) the reaction of (1) is carried out in the presence of cobalt acetate at 80-90 DEG  C.

Title: Improvements in or relating to pulse triggered oscillation generators
Inventor: DAVIES ERIC
IPC: H03K3/30
Filed: 1965-02-18
Abstract: 1,074,975. Keying carrier frequencies. MARCONI CO. Ltd. Dec. 29, 1965 [Feb. 18, 1965], No. 7086/65. Heading H3R. A Hartley oscillator comprising a transistor (T1) having a tuned circuit (L1, C1) in its collector circuit and triggered by pulses applied to the base of the transistor, is characterized by a capacitor (C2) connecting a tapping on the tuned circuit to the emitter of the transistor. This capacitor is charged from the power supply when the circuit is not oscillating, and when the circuit starts oscillating supplies energy to the circuit so that the first oscillations are of the same amplitude as subsequent oscillations. A resistance (R4, Fig. 2, not shown) may be included in series with the capacitor to prevent the first oscillations exceeding the amplitude of subsequent oscillations. At the end of a pulse the amplitude of the oscillations decays exponentially. This may be avoided, if desired, by connecting a second transistor (T2, Fig. 3, not shown) across the tuned circuit to provide critical damping when the transistor conducts; the transistor (T2) is caused to conduct at the trailing edge of a pulse by means of a differentiating circuit (C3, L3) to which the pulses are fed. The input pulses may be limited .by a Zener diode (D1) in parallel with a potentiometer (R2).

Title: Production of high molecular weight alkylpolysiloxanes
IPC: C08G77/06
Filed: 1951-03-27
Abstract: In polymerizing alkylpolysiloxanes, one or more lower molecular weight alkylpolysiloxanes are heated to below their temperature of decomposition in an autoclave, the temperature and time of heating being adjusted in relation to the proportion of the volume of the autoclave occupied by the starting material and to the degree of polymerisation desired.  The molecular size of the polymer is increased by increasing the time of the reaction at constant temperature or by reducing the time and increasing the volume of the starting material in the autoclave.  Temperatures from 200 to 450 DEG C. are usually used.  The process may be used to polymerise cyclic polymers of the formula [(CH3)2SiO]n, where n is 3, 4, 5 o 6, or to form copolymers from low molecular weight polysiloxanes having, e.g. 1.9-3 : 1 similar or dissimilar alkyl groups per silicon atom, such as cyclic dimethyl- and diethyl-polysiloxanes, or cyclic dialkyl polysiloxanes and linear polymers of the formula R3SiO (R2SiO)n SiR3.
