Title: Improvements relating to the separation of sraight chain hydrocarbons
IPC: C10G25/03
Filed: 1962-02-21
Abstract: A cyclic process for the separation of straight chain hydrocarbons from mixtures containing them by means of a 5 <\>rA molecular sieve, and comprising alternate absorption and partial desorption stages, is characterized in that fresh or regenerated sieve, containing no absorbed hydrocarbons, is subjected to a longer absorption period than the period employed in subsequent absorptions, for example 2-10 times the length.  The initial absorption is preferably effected 20-30 DEG C. below that of the subsequent absorptions.  A number of beds may be provided to enable each to be regenerated in turn. The sieve bed may be subjected to a long desorption period prior to regeneration.  A purge stage may be interposed between absorption and desorption, for example using an inert gas such as nitrogen.  This inert gas may also be passed with the feedstock to the absorption stage. The desorption may be effected with a normal paraffin of lower boiling point than the lowest normal paraffin in the feedstock, which may be a petroleum fraction boiling in the range 150-400 DEG  C., in which case preferred operating conditions are: Temperature 300-400 DEG  C.  Pressure 50-300 p.s.i.g.  Space velocity 0.1-5 v./v./hr. Inert gas flow rate 10-500 v./v./hr.  Purge gas rate 10-500 v./v./hr.

Title: Improvements in or relating to automatic central buffer couplings
IPC: B61G3/16
Filed: 1934-03-06
Abstract: 413,245. Automatic couplings for railway -vehicles. KRUPP AKT.-GES., F., Essen, Germany. March 6, 1934, No. 7118. Convention date, March 30, 1933. Addition to 384,560. [Class 103 (v).] In an automatic coupling incorporating a locking-pawl B and a controlling spring or like member F therefor as described in the parent Specification, the spring element and the releasing-lever C are connected to the pawl B about co-axial pivots b<2>. The spring element comprises a connecting-piece D pivoted on the pawl B and having a cylindrical extension d<1> on which slides a tubular member e<1> terminating in a guide member E. On the latter is a doubly inclined projection e<2> engageable by a nose c<5> on the lever C, which is also provided with a surface c<1> and two recesses c<2>, c<3> coacting with a lug a<6> on the coupler-head. Assuming the parts are in the coupled position as shown in Fig. 1, uncoupling is effected by moving one of the levers C outwardly, e.g. the upper lever, whereby the lug a<6> is brought into engagement with the recess c<2> and forms a pivot for the lever C. Thus the pawl B and pivot b<2> are retracted to the position shown in Fig. 2, and simultaneously the nose c<5> bears against the guide-piece E and compresses the spring F. A similar movement is imparted through an interconnecting element as described in the parent Specification to the other pawl B, pivot b<2> and guide-piece D. The pawls B are thus placed in such a position that, when the coupler-heads are drawn apart, the inclined surfaces on the latter cause the pawls B to be pushed further into their respective heads, while the lug a<6> is disengaged from the recess c<2>, thus permitting the spring F, as the coupler-heads separate, to rotate the lever C in the direction X, Fig. 2, and ultimately restore the parts to the position shown in Fig. 1. If the lever C is pushed to its extreme outward position the lug a<6> is engaged within the recess c<3>, and the coupling is rendered inoperative, e.g. for shunting purposes.

Title: Improvements in transformer constructions
IPC: H01F38/10
Filed: 1962-02-23
Abstract: 930,630. Transformers. GENERAL ELECTRIC CO. Feb. 23, 1962 [Feb. 27, 1961], No. 7156/62. Class 38 (2). A transformer has a U-shaped core part 2a composed of bent laminations, a yoke 11 of flat laminations, a reactive shunt formed of at least one stack of flat laminations 16, 17 the laminations being in edge to edge relationship where the parts touch, and a primary and secondary winding on opposite sides of this shunt. Each winding may consist of a pair of coils and the part of the core carrying the secondary winding 6, 7 may have a restriction 5 to create a saturable section. In a modification two U-shaped parts may be arranged to provide two magnetic loops with one arm of each U combined to make a centre leg on which are arranged single coil windings, Fig. 5 (not shown). The U-shaped parts are made by cutting across the straight sides of an elongated loop of wound magnetic strip impregnated with resin. The yoke laminations are held together by plate 13 and fastened to member 2a by steel strap 14. Reactive shunts 16, 17 may be held by tape until the whole transformer is assembled in a container and potted. Paper insulates the windings from the core at 10 and paper or a resin or oxide coating forms an air gap at 12a between the yoke and the U-shaped core part to give the desired primary magnetizing reactance.

Title: Adaptive anti-lock brake controls
IPC: B60T8/88
Filed: 1976-02-25
Abstract: 1494064 Anti-lock braking GENERAL MOTORS CORP 25 Feb 1976 [27 March 1975] 07390/76 Heading F2F An antiskid control apparatus comprises a speed selector 20 which transmits the lowest, highest or an average of the monitored wheel speeds which is then differentiated at 34 to represent wheel decelerating and summed at point 38 with a signal representing a vehicle deceleration reference, the resulting algebraic sum signal then being fed to a release integrator 36 whose output represents the difference between the selected wheel speed and vehicle speed (velocity error) and which output is then fed to a release comparator 40 which compares the velocity error with a threshold value indicative of incipient wheel lock-a value of 5 m.p.h. changing to 3 m.p.h. on brake release and an additional contribution from a variable threshold circuit 48 increasing linearly with wheel speed at the rate of 1 m.p.h. for each 10 m.p.h. increase in the selected wheel speed-and outputs a logical signal to solenoid driver 30 if the threshold is exceeded. A deceleration switch 26 also causes brake release if the wheel deceleration value exceeds a high limit value of 1 or 2, indicating incipient wheel lock. The signal provided at point 38 representing the deceleration reference is made up of the outputs from an acceleration follower 42 whose output is a function of positive wheel acceleration and from a delayed g level circuit 44 whose input is taken from the output from release comparator 40 and which adds a gradual 0À8 g contribution to the deceleration reference at a short delay after brake application but whose output signal is terminated on brake release. Each time release comparator 40 terminates the release signal and the corresponding signal on line 45 triggers an integrator reset circuit 49 which biases release integrator 36 to a zero velocity error condition. The apparatus also includes a self-checking facility whereby a self check accelerometer 58 monitors wheel acceleration and immobilizes the apparatus to give normal braking and simultaneously lights a warning lamp if both wheel deceleration and velocity error are small indicating a circuit malfunction and also functions with timer 60 and re-apply circuit 62 to re-apply if either wheel acceleration exceeds 0À5 g or wheel deceleration exceeds 1.5 g for a predetermined time period.

Title: Computer sotrage system
IPC: G06F12/06
Filed: 1972-02-17
Abstract: 1382903 Digital calculators PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 17 Feb 1972 [20 Feb 1971] 7407/72 Heading G4A A computer system includes first and second storage areas containing storage locations which are accessed by corresponding addresses. The sequence of addresses corresponding to locations in the first area is separated from the sequence corresponding to the second area locations by a sequence of "void" addresses which represent no corresponding storage locations. The first, void, and second sequences of addresses form an unbroken sequence of numbers. The system includes means for calculating from at least two component or partial addresses a complete address which specifies a location. Prior to the determination of a complete address a detector inspects a portion of at least one partial address and in consequence requests access to one or other of the storage areas. If the complete address subsequently indicates a void address the request is cancelled and an error signal is generated. The first area has 2<SP>l</SP> usable locations. The second area consists of 2<SP>m</SP>-l(m #1) modules each containing 2<SP>l+p</SP> locations, and there are 2<SP>l</SP>(2<SP>p</SP>-1) void addresses, p#1. The provision of the void addresses obviates the necessity of cancelling the access request to the first area and replacing it by a request for access to the second area should the complete address not indicate a location in the first area. In an example each partial address consists of portions m, p and l. The detector inspects m and p of the partial address and if they are all 0 it requests access to the first area M1. If m or p contain a 1-bit access to M2 is requested. When the complete address is calculated, by addition of the partial addresses, its corresponding portions m and p, and a higher order portion n, are inspected by a detector. If area M1 had been requested and p contains a 1-bit, the complete address is a void address and the request is cancelled. If area M2 had been requested and there is a 1-bit in portion n due to carry from m the request is cancelled as the complete address indicates a location in a void, or non-existent, area beyond M2. In the absence of such a carry bit portion m indicates in which of the modules in M2 is the location indicated by the portion p, I, each module having 2<SP>l+p</SP> locations. The total storage field may comprise several storage areas with addresses separated by void addresses, the length of each sequence of storage and void addresses being an integral multiple of the length of all the preceding storage and void address sequences.

Abstract: 1,255,896. Fluid regulation. HONEYWELL Inc. Feb. 18, 1970, No. 7777/70. Heading G3H. A fluidic oscillator 10 comprises two housing parts 11 and 12 each formed with a chamber 15 and a converging - diverging passage 18, and a plate 13 formed with a knife-edge 21 and two longitudinal extensions 20, the plate, when sandwiched between the two housing parts, defining with the parts an inlet orifice located oppositely to the knife edge 21. Accordingly, fluid entering the inlet orifice is caused by the knife edge to oscillate between the two chambers 15 so providing pulses alternately from the two passages 18. The configuration of passages 18 ensures chocked flow and hence insensitivity to pressure changes. When used in conjunction with other apparatus, (37), Fig.4 (not shown), for sensing the temperature of fluid flowing through the oscillator, such as fluid from the combustion chamber of a gas turbine engine, the oscillator is surrounded by an insulated jacket (30) having an inlet port from which part of the fluid passes to the oscillator inlet port and the remainder to the space between the oscillator and jacket. Furthermore, the connection between the apparatus and oscillator is effected by means of a resonator tube (35). In an alternative arrangement, channel 19 in housing part 12, is connected directly to a transducer, amplifier and electronic counter (38, 39, 40).

Title: Improvements in travelers for ring spinning and twisting frames
IPC: D01H7/60
Filed: 1924-03-27
Abstract: 228,738. Wentworth, P. C. March 27, 1924. Spindle apparatus.-Travellers for spinning and twisting machines are scalloped as shown at S in the bow portion B so as to flex more readily when sprung on to the ring, and are treated so that the horns H are harder than the bow portion. They are formed from stock of low carbon content and of uniform thickness and are heated in a furnace for six or seven hours with bone black and quenched. The bows respond more quickly to the subsequent tempering process, so that by suitably timing the operation they are left resilient and the horns hard. The invention is applicable to the vertical type of traveller. Specification 174,068 is referred to.
