Filed: 1936-12-07
Abstract: 470,316. Cartons, pots, &c. GEE, L. F. Dec. 7, 1936, No. 33475. [Classes 18 and 66] Containers or receptacles such as pots or cartons, particularly pots which are hermetically sealed after filling and mainly composed of paper, papier machÚ, cardboard, &c. are constructed so that the sealed end may be severed and used as a loose cover, by forming the bodies of laminations a, a' waterproofed by means of wax &c. with longitudinal overlapped joints of which the outer lamination has a ripstrip k, the closure g being held only by a curled edge h of this lamination so that when a tab k<1> is pulled to sever the end, the end structure may seat on the inner lamination and form a removable lid. In another form a blank or blanks is or are rolled or wound to form the laminations, the rip-strip terminating at the lapped joint so that the lid remains hinged to the body. In either form the upper edge of the inner lamination may be turned over inwardly. The pots may be cylindrical and may have additional laminations provided by additional tubular wall layers or by lengthening the blank which is rolled. The closure may be in the form of metallic end caps.

Title: Control arrangements for conveyors
IPC: B65G47/50
Filed: 1972-07-10
Abstract: 1338053 Sorting letters &c. ELLIOTT BROS (LONDON) Ltd 10 July 1972 [16 July 1971] 33567/71 Heading G4H [Also in Division B8] A control arrangement for a conveyer 3 for distributing articles 2 from a dispatch point to destinations D1, ..., D64 (e.g. sorting letters) comprises a register 6 having 512 stages corresponding to successive portions of the conveyer route AB, means 1, 4, 5, 8 for supplying to the first stage of 6 an address indicative of the number of the portion of the route forming the destination of an article at the dispatch point, a pulse unit 9 for transferring an address from one stage of 6 to the next as the associated article moves from one portion of the route to the next, an oscillator 11 operative between transfers to step each address to the last stage of 6 and back through the first stage to its original stage while a counter 512 counts down from 512 to indicate the original stage of each address as it appears at the last stage, and means responsive to the coincidence of an address in the last stage of 6 and the count in 12 to effect the removal of the article from the conveyer 3. In the embodiment of Fig. 2 the address comprises the last six binary digits of the destination portion number, and hence of the corresponding stage in 6 (if this were not so, then more gates would be required as in the embodiment of Fig. 1). The output from 12 is also converted to octal form at 22-24 and enables one of 64 gates 25 (8 degree output being common to all signals): the outputs from 25 and 21 together activate one of 64 destination stores 14, thereby operating a diverter 16 at the destination of the article. Each address is applied to a store 1 via a keyboard or apparatus scanning code marks on the article: initial movement of the article interrupts a light beam to produce a signal 8 which causes the transfer of the address in 1 to register 6 on the next pulse 9.

Title: Apparatus and process for the controlled cooling of rods
IPC: C21D9/52
Filed: 1963-08-26
Abstract: <PICT:1024713/C6-C7/1> A method of cooling a rod comprises forming the rod from a rod rolling mill into a series of nonconcentric rings at transformation temperatures, supporting them on a plurality of supports, passing a cooling fluid (preferably air under pressure) through the rings and collecting them as a bundle.  The rod may be first cooled from the rolling temperature (e.g. 1800  DEG F.) to above the transformation temperature at 1200-1500  DEG F. (e.g. by water cooling).  In Fig. 2 the rod 4 passes through a pipe 6, which may be water cooled and into the laying head 10 which deposits the coils 20 on the conveyer 12.  The conveyer passes the coils under the influence of blown air to be collected as coil 22. In order to cool all the metal in the rod at the same rate, the flow of the cooling fluid may be regulated by means of valves as shown in Figs. 7 and 8 (not shown) or by means of a hood arrangement as described in connection with Fig. 3 (not shown).

Abstract: 988,271. Semi-conductor bi-stable circuits. SPERRY RAND CORPORATION. Sept. 4, 1962 [Dec. 22, 1961], No. 33824/62. Heading H3T. In a circuit for a punch card reading device, a silicon controlled rectifier (SCR) 11 is connected in series with a variable current device (transistor T2) which may be biased to be either conductive or non-conductive. The device is normally biased to be conductive, so that positive read-in or probe signals applied to the gate of SCR11 cause the series circuit to pass current from the + 12v supply through the load resistor, SCR11, transistor T2 to earth. This circuit remains conductive after the termination of the read-in pulse, thus storing it. In order to read out the information stored, a positive read-out pulse is applied to terminal 21 to switch on transistor T1, and switch off transistor T2, thus terminating the current through the SCR11 to produce an output pulse on line 23. A number of similar SCR circuits 26, 27, 29, 31 may be connected to a common transistor T2 so that all are read out together.

In a direct-coupled transistor amplifier comprising a plurality of stages, stabilization of the operating point of a later transistor is provided by direct-current negative feedback to an earlier stage of the amplifier through a further transistor operating as a stabilizer for reducing variations in the operating point of said later transistor. As a consequence, as may be seen from the circuit of Fig. 2, the stabilizing transistor VT1 may be biased from a potentiometer chain R 1 , R 2  of sufficiently low impedance to provide the desired stabilization while the potentiometer chain R<SP>1</SP> 1 , R<SP>1</SP> 2  for biasing the input transistor VT1A may be of sufficiently high impedance not to attenuate unduly the input signal. Capacitor C 2  which may be connected as shown in solid or in broken lines bypasses the alternating-current component from the feedback path. Resistor R 2  may be replaced by a Zener diode. Signal negative feedback may be coupled through capacitor C 3 . In a modification. Fig. 3 (not shown), the amplifier input transistor is of NPN type and has its collector connected to that of transistor VT1. In a further modification, Fig. 4 (not shown), feedback is taken from the collector circuit of the output transistor and applied to the base electrode of the stabilizing transistor VT1.

Title: Ultrasonic thickness measurement
IPC: G01B17/02
Filed: 1966-08-01
Abstract: 1,093,459. Ultrasonic thickness measuring. DR. J. U. H. KRAUTKRAMER GESELLSCHAFT FœR ELEKTROPHYSIK. Aug. 1, 1966 [Aug. 4, 1965], No. 34367/66. Heading H4D. In an ultrasonic pulse-echo system for indicating reduction of the wall thickness of a test specimen below a prescribed minimum value, an ultrasonic delay line is used to define the open time of a time gate which closes immdiately before the expected arrival of the rearsurface echo from a specimen wall of the said minimum thickness and an alarm is actuated if the rear-surface echo from the test specimen falls within the open time of the gate. In the embodiment of Fig. 6, an electrical pulse corresponding to the front-surface echo received from a specimen by a conventional pulse-echo instrument 12 is selected by unit 13, passed through electrical delay line 15 (providing a fixed delay at least equal to the duration of the front surface echo) and opens gate 20. The electrical pulse is also converted into an ultrasonic pulse, delayed, and reconverted to an electrical pulse in components 16, 17, 18 respectively, constituting a piezo-electric or magnetostrictive delay line, and the reconverted pulse closes gate 20. The reception of any rear-surface echo within the open time of the gate 20 is detected by coincidence stage 21 and causes actuation of alarm 22, actuation of the alarm by the front-echo pulse being prevented by the delayed opening of gate 20. By thus comparing the transit time of an ultrasonic pulse through the wall of the specimen with the gate-open time defined using the ultrasonic delay line, it is stated that thickness measurement accuracy is improved over known systems in which the comparison is made with a purely electronically produced gate interval subject to variations due to temperature effects, operating voltage and ageing of component parts. The ultrasonic delay component 17 may take the form of interchangeable cylinders of various thicknesses to suit the thickness to be measured, and may be of the same material as the test specimen to permit direct comparison of thickness. In a modification, delay line 15 is dispensed with and a tapping on the ultrasonic delay component 17 provides the fixed delay for the gate-opening pulse. Details of known ultrasonic pulse-echo thickness measuring systems (Figs. 1 to 5, none shown), are given.
