Abstract: 817,690. Collapsible boxes. WHEELING STEEL CORPORATION. May 1, 1956 [July 1, 1955], No. 13366/56. Class 18. [Also in Group XXX] The top 2, Fig. 1, of a box pallet or box is drawn from metal or plastic sheet and has downwardly dished' areas 18 which receive the feet 19 of the bottom of a similar box in a stack so that the sheet material of the dished areas is loaded in tension. As illustrated the top 2 is formed with strengthening ribs 5, with a turned over edge 31, Fig. 2, and with a peripheral channel 6 shaped to take over the rolled ever edges 11 of the sides 7 of the container or over channel-section members (not shown) fitted over the rolled over edges 11. The sides 7 are also drawn from sheet and are formed at the corners with portions 8 which can be fitted together as shown in Fig. 4 before a tube 9 is slid over them to secure the walls together. Embossings 20, Fig. 9, formed in the sides 7 contain reverse embossings 21, and slits 10 are cut to receive belly bands.

Title: Hydraulic system
IPC: F15B11/024
Filed: 1943-08-18
Abstract: 566,460. Hydraulic apparatus. ERNST, W. Aug. 18, 1943, No. 13440. Convention date, April 5, 1943. [Class 69 (ii)] A plunger 3 is connected to a part to be controlled, and carries a piston portion 4 with faces of unequal areas, acted on by liquid supplied by a pump 20 through a valve 17 during the first part of a stroke in one direction, a byepass 9 connects the two piston sides, and is closed during the latter part by rise of pressure. On shifting the valve handle 24 from neutral to lower position, the pump pressure line 19 is opened through a line 18 to the right-hand cylinder end, and a conduit 15 is connected by an exhaust line 23 to the tank 22 from which the pump draws. The plunger moves to the left under no initial resistance and the liquid on the left-hand side raises the byepass valve 26 and acts on a spring- controlled plunger 10 to open a port 8 to the right hand end. When the plunger encounters resistance pressure rises in conduit 18, and is conveyed through a pilot line 43 and check valve 42 to a valve casing 29 shifting the double piston valve 32 to the left to open the left hand end of cylinder 2 through conduits 28, 30 to the tank 22, thus lowering the pressure and allowing valve 26 to close and the spring plunger 10 to be returned. A choke 40 maintains pressure in conduit 38 to hold the valve 32 open. During the retraction stroke, with the valve 17 in its uppermost position, the pump delivers to the left hand end through a pipe 15 with a check valve and also delivers to the rear of the spring plunger 10 holding it closed. The right-hand cylinder end, and the valve 32, are open to the low pressure of the exhaust line 23, the valve being closed.

Abstract: Derivatives of the choline type of the carbamic acid series are manufactured by reacting substances of the general formula H2N.CO. O X, where X is a substituted or unsubstituted dialkylaminoalkyl radicle, with compounds which contain labile aliphatically-bound halogen.  Alternatively, halogenalkyl esters of carbamic acid are reacted with tertiary bases.  The products are employed for therapeutic purposes.  In examples: (1) carbamic acid b -diethylaminoethyl ester (obtainable by the reaction of diethylaminoethanol hydrochloride with urea hydrochloride) is treated with methyl iodide to produce its methiodide; (2) the same compound with ethylene iodohydrin yields its b -oxyethyl iodide; (3) with b -iodoethylurethane the iodo-(aminoformyl-b -oxy)-ethylate is produced; (4) o -bromacetophenone similarly yields the phenacyl bromide; (5) b -iodoethylurethane with trimethylamine gives the methiodide of carbamic acid-b -dimethylaminoethyl ester; (6) carbamic acid a -methyl-a -ethyl-b  - dimethylaminoethyl ester (obtainable from a -methyl-a -ethyl-b -dimethylaminoethyl alcohol hydrochloride and urea hydrochloride) is treated with methyl iodide to produce its methiodide; (7) hordenine base and b -iodoethylmethane yield the iodo-b -(4-oxyphenyl)-ethylate of carbamic acid b -dimethylaminoethyl ester; (8) pseudo 1-phenyl-1-(aminoformyl)-oxy- 2 - dimethylaminopropane (obtainable from pseudo 1-phenyl-1-oxy-2-dimethylaminopropane hydrochloride and urea hydrochloride) is treated with methyl iodide to produce its methiodide.

Abstract: 1,221,835. Polyarylsulphones. MINNESOTA MINING & MFG. CO. 21 March, 1968 [22 March, 1967], No. 13769/68. Heading C3R. Polyarylsulphones in which the main chain contains -SO 2 - groups and aromatic rings, have amino, hydroxyl and/or carboxyl groups attached to main chain aromatic rings or terminal aromatic rings, either directly or through other groups. The polymers are prepared from the polyarylsulphones described in Specification 1,182,501, which have carboxy anhydride groups attached to aromatic rings in the polymer chains and/or at the ends of the chains, by reaction with a compound having at least one amino, hydroxyl or carboxyl group and a group, e.g. an amino or hydroxyl group, which opens the anhydride ring and links with one of the carbonyl groups. The polymers of the invention can be reacted with other polymers and monomers to form graft and block copolymers. In examples, polyarylsulphones having carboxy anhydride groups are prepared from diphenyl ether 4,41-disulphonyl chloride, diphenyl ether, 4,5-diphenoxy phthalic anhydride, phenyl ether disulphonyl chloride, biphenyl, biphenylmonosulphonyl chloride and 4-phenoxy phthalic anhydride; these polymers are then reacted with p-aminophenol, oxydianiline and p-aminoacetanilide to form polymers of the invention which are further reacted with an epoxy novolak polymer, pyromellitic dianhydride and isophthaloyl chloride.

Title: Circuit arrangement for the evaluation of received remote control signals
IPC: H04N5/44
Filed: 1975-04-04
Abstract: 1508491 Pulse circuits LICENTIA PATENT VERWALTUNGS GmbH 4 April 1975 [5 April 1974] 13827/75 Heading H3P [Also in Division G4] A circuit for the evaluation of received remote control signals of a predetermined frequency f 1  includes an oscillator 34, providing oscillations of a frequency higher than f 1  which are fed to a counter 22 controlled by the received signals in such a way that, in the presence of the received signals, the counter gives a pulse during each period thereof, and, upon drop-out of the received signals the oscillations are divided by the counter to said frequency f 1  to provide a substitute for said control signals. As described a TV receiver is remotely controlled by ultrasonic signals offrequencies f 1  and f 2 . The first frequency f, characterizes the control (e.g. programme selection) and the second frequency f 2  represents the actual order the signal is evaluated by counting periods. The signals are received by a microphone I and resonant circuits 2 which provide a '1' output 3 (4) if f 1  (f 2 ) is is absent. If f 1  (f 2 ) is present, a 0 1 signal appears at 3 (4) during the first and second half-periods respectively, e.g. Fig. 2a. Receipt of f 1  or f 2  triggers respective retriggerable monostables 12-14 or 6-10, and gates 11, 45 are enabled only in the absence of f 2 . Receipt off, (t 1 -t 4 ): pulses pass through gate 11  to counter 22 and gates 15-21, 30 and 31, arranged so that counter 22 cannot count pulses from 34 until the second half-period, when an output pulse from gates 30-31 begins at a count of 4 and ends at the end of the half-period (23, 24 are reset inputs for the counter). This pulse passes through gate 45 to a further part of the evaluating circuit. f 1  drops out (t 4 -t 6 ): the signal amplitude is insufficient to retrigger monostable 12-14. A pulse from 30, 31 begins at a count of 4 as before, but now counter 22 is not reset at the end of the half-period but at a later count: counter 22 and its associated gates act as a frequency divider to produce pulses at a frequency f 1  which pass through gate 45. The dividing and pulse-producing stops when monostable 12-14 times out: its duration is chosen to be greater than the maximum anticipated dropout period (#9 msec. here). When the drop-out ceases, operation is as before (t 7 ). When f 2  starts, monostable 6-10 is triggered and gate 11 is blocked (thus any f 1  pulses caused by echoes have no effect). There are still pulses of frequency f 1  produced at 30, 31 but gate 45 is now blocked as long as monostable 6-10 continues to be triggered. When pulses f 2  end, the monostable times out and counter 22 is reset.
