Abstract: 316,972. Electra Apparatenbau Ges., (Assignees of Matzka, 0.). Aug. 7, 1928, [Convention date]. Affixing stamps &c.-A hand apparatus for affixing stamps &c. comprises a verticallyreciprocating press plate with interconnected means for feeding the stamps from a strip, severing the stamps, &c. and moistening the surface to which it is to be affixed, the feeding means comprising a pivoted cam plate with a link to an oscillating pawl engaging recesses on a disc mounted on the shaft of a feeding roller. The press plate 15, Fig. 2, is carried by a frame 17 normally abutting against a top plate 13 under the tension of a spring 16. The press plate is operated, with some lost motion, by a sliding, spring-returned tube 9 the lower end of which carries a pawl 22 adapted to engage a projection 21<a> on a spring-influenced knife 21. the depression of which severs a previously fed stamp from the strip. The pawl 22 is freed by the engagement of its lower end with the press plate, the knife being thus returned by the springs 20 before the actuation of the press plate. The stamps are fed from a roll 27 between guide plates 32, 33 by a pair of interengaging rolls 28, 29 the former being fitted with pins 31 riding in a groove in the latter. The bottom roll 29, together with the guide plate 33, can be removed for inserting the strip. The shaft of the upper roll 28 carries a disc 43, Fig. 1, with recesses engaged by a. retaining pawl 46 and an operating pawl 44 carried on a crank 41 operated by a link 39 connected with a pivoted plate 38. The plate 38 is operated by a projection 36 on the tube 9 engaging its edge and is returned by a spring 38<a>. A similar plate, similarly operated, is mounted at the other side of the apparatus and its lower end engages, in turn, the arms 48 of a spider on the other end of the shaft of the feeding roll to limit its rotation at the end of a feeding stroke. The end stamp is temporarily supported by a pair of pivoted spring flaps 53 which are moved out of the way on the depression of the press plate. The surface is moistened by a spring-influenced pad 49 connected by links to the lower ends of the plates 38.

Title: Improvements in and relating to tipping vehicles
IPC: B60P1/16

Abstract: 500,232. Tipping-vehicles. BROMILOW & EDWARDS, Ltd., and SWIFT, H. W. Aug. 23, 1937, No. 23048. [Class. 108 (i)] Control apparatus for tipping gear including a ram or rams and a pump for supplying liquid thereto for tipping bodies on vehicles, comprises a valve-casing 1 containing a fullstroke valve 6 which is adapted to be opened by mechanism actuated when the body reaches the maximum tipping angle, e.g. 55‹, to allow liquid to flow through a branch circulating duct 5 shunting- the ram cylinder, the casing containing also a byepass 10 for the valve 6 including an overload relief valve 13 by means of which circulation through the byepass 10 is effected under'any overload conditions. As shown, the valve casing 1 has unions 2, 4, 12 adapted to be connected respectively to the delivery side of the pump, to the ram cylinder or cylinders, and to the oil tank or reservoir, the unions 2, 4 being directly connected by a duct 3. The spring-pressed ball-valve 6 is adapted to be opened by a plunger 8 which is mechanically associated, preferably by a linkage or lever system and a flexible cable, with a portion of the body which moves appreciably during the tipping operation. Thus when the body is raised the liquid circulates while the pump remains operating, sufficient residual pressure being maintained in the ram cylinder to hold the body raised. The plunger may have an over-riding manual control which may supplement the usual valve control in the driver's cab of the vehicle and whereby the body may be raised to and held in any intermediate position or the fully raised position. For three-way tipping bodies, the flexible cable is attached in the centre of the body so as to participate in all the tipping movements and .the lever system includes a longitudinally-extending rocker-shaft equipped with the over-riding control handle. The valve 13 comprises a spring-pressed ball, the spring pressure on which is adjustable by a removable sleeve-nut 15. The invention is stated to be particularly'suitable for use with the tipping gear described in Specification 499,227.

Abstract: 1,045,663. Sampling liquids. TEXSTEAM CORPORATION. June 1, 1965 [Aug. 26, 1964], No. 23256/65. Heading B8N. [Also in Division F1] A device for taking a sample from a pipeline 10 carrying, e.g. oil, comprises a pump 16 having a suction and discharge heads 17, 18 respectively, a solenoid-actuated valve 22 connected, via pipes 20, 25, 27, to the discharge head, a sample container 26 and the pipeline respectively, and means for operating the valve in response to the volume flow through the pipeline. The pump 16, which may be of a reciprocating-piston type, is adapted to be normally driven continuously so that with the solenoid-actuated 22 in a position to connect the discharge head 18 with the pipeline via the pipes 20, 27, the oil is withdrawn from and then returned to the pipeline. When it is desired to take a sample, a flow measuring device 14, Fig. 1 (not shown), is set so that after a certain flow a switch is operated to actuate the solenoid and so move the valve into a position in which the discharge head is connected to the sample container and the connection to the pipeline closed. After one reciprocation of the pump a switch is actuated to return the valve to its initial position. When a representative sample is required to be taken from the number of examples in the container, the latter samples are first mixed by closing a valve 36 opening a valve 35 and starting a pump 29 so that the oil is circulated through the container and pipes 34, 37. The pump is then stopped and a valve 40 opened so that the sample may be removed. The oil remaining in the container may be returned to the pipeline by closing the valve 35 and opening the valve 36. The sampling device may be used for inserting metered amounts of chemicals into a pipeline.

Abstract: 1351091 Thermal analysis GENERAL MOTORS CORP 18 May 1972 [27 May 1971] 23352/72 Heading G4A The metallurgical properties of a sample of molten cast-iron treated to form nodular castiron on solidification are predicted by (a) measuring the temperature of the sample at predetermined increments of time during an interval in which the sample cools from a liquid to a solid to determine a cooling curve, (b) storing the measurements in an electronic digital computer, (c) differentially analysing the measurements to determine (1) a first set of signals corresponding to the points of inflection of the cooling curve and (2) a second set of signals corresponding to points of minimum radius between the points of inflection and (d) storing the two sets of signals in matrix form as a function of independent variables such as absolute time and temperature. Known matrices obtained in similar manner from samples having known properties are correlated using regression analysis to determine the independent variables required to predict particular properties, these variables then being operated on to make predictions for the unknown sample. A sampling device (see Division H1) for determining the cooling curve includes a thermocouple assembly the output leads from which are coupled to a digital computer which stores the measured temperatures. The inflection points represent the temperatures at which the heat of solidification given by the samples are either a maximum or a minimum. They are computed by examining the first five measurements to determine the slope of the curve at the third measurement point, this process then being repeated for the second to sixth samples, &c. The maximum and minimum slopes are then selected to identify the points of inflection to derive the first set of signals. The points of minimum curve radius are computed by finding the minima of the equation where T is temperature; t is time to derive the second set of signals. These signals are stored in matrix form as functions of absolute time, temperature, temperature decay rate, curve radius and time and temperature differentials. Known matrices obtained in like manner from similar samples with known properties are correlated by a series of regressive analyses of the form where Y is the property to be predicted, A 0  is a constant dependent on this property, A 1 -A j  are numerical coefficients and X 1 -X j  are the stored independent variables selected by operating successively with each independent variable as X 1  to determine which gives the best prediction of the known property and then trying the remainder of the variables as X 2  &c. Predictions for the unknown sample are then effected by using the stored variables as the appropriate independent variables X i .
