Filed: 1925-09-28
Abstract: 240,828. Bergmann Elektricitõts- Werke Akt.-Ges. Oct. 3, 1924, [Convention date]. Constant-speed control systems only. -Rotary printing and like machines, such as calendering- machines, are driven by a single electric motor so arranged that it can drive the machine at a low speed at the commencement of the printing operation, and subsequently at a high speed. When driving at the low speed the motor is controlled automatically so as to keep the speed constant when the load varies, the automatic control acting by varying the resistance in the armature circuit, or by other means. The armature a of the motor is controlled by a slip resistance f, and the field winding b by a step resistance h. The web is threaded in the position 1 of the contact arm g of resistance f, and between the steps 1, 2 is an adjustable portion k of the armature resistance f in series with a magnetizing coil l. The msistance k is automatically regulated by a spring controlled armature m in the coil l connected to a contact bar o. If the current is great, the resistance k is short-circuited by the bar o, but as the current decreases the resistance k is partly or entirely traversed by the armature current.

Title: Flameless reaction to olefines of gaseous or vaporous saturated hydrocarbons
IPC: C07C4/02
Filed: 1956-08-09
Abstract: In a process for the production of gaseous olefines by the partial oxidation of gaseous or vaporous saturated hydrocarbons having at least 2 carbon atoms in the molecule, the mixed gases are led through a free space in which their speed undergoes reduction by at least one half, then through a thin loose layer as defined below of a heat-stable, inert, granular material, and are reacted in a fluidized bed of an inert, heatstable solid.  By a thin layer is meant one through which a gas does not undergo any marked loss in pressure and in which the residence time is so short that a surface combustion cannot fully develop under the conditions employed; the grain size may be 5 to 20 mms. and the layer thickness 5 to 20 cms.  The speed of the mixed gases in the free space is preferably reduced to less than one-fifth. Atmospheric, increased or reduced pressures e.g. up to 30 atmospheres at 600-1000 DEG  C. may be used.  Oxygen-containing gases such as air may be used as the oxidizing gas and steam may be added.  In an example propane, oxygen and steam are passed through a fluidized layer of sillimanite at 600 DEG  C. yielding a cracking gas rich in ethylene.  The reactants prior to passing through the fluidized bed pass through a conical space where the speed is reduced and an 8 cms. deep layer of 5 mms. diameter porcelain balls.

Patent GB-964032-A (GB)
Title: Improvements in and relating to adder circuits
IPC: G06F7/38
Filed: 1961-07-07
Abstract: 964,032. Binary adders; multipliers. INTERNATIONAL BUSINESS MACHINES CORPORATION. July 7, 1961 [July 29, 1960], No. 24616/61. Heading G4A. Electronic binary adders and single order binary multipliers are constructed of arrays of two sets of conductors, one set of conductors energizing current inhibitors which steer currents flowing in the other set to terminals, energization of which indicate the result of the addition or multiplication. As described the inhibitors are cryotrons. Fig. 5 shows an adder in which the values of the two operands are entered by causing current to flow in line 26 or 27 and line 28 or 29. The inhibitors, such as 80, thus energized direct currents from terminal 40 to terminal 43 or 46 to represent the sum digit and to terminal 62 or 65 to represent the carry digit. Fig. 14 shows a multiplier in which the operands are entered by energizing one out of each of the pairs of lines 401, 403 and 405, 407, and the result appears as a current at terminal 425 or 427. The Specification is concerned with the use in parallel adders and multipliers of what it calls add-one adders, i.e. adders in which a single order addend is added to a multiorder augend. Fig. 8 shows in block form an R3 add-one adder. The single order binary number b is added to binary number a3... a1 to produce an answer c3... c1. Although an extra pair of outputs may be provided to indicate carry from c3, such an arrangement is not necessary in the parallel adder to be described. Fig. 10 shows a parallel adder of eight-bit numbers, and in broken lines the additional circuitry to cope with nine-bit numbers. Level 1 consists of eight R1 adders with carry outputs. With each pair of successive R1 adders is associated an R2 adder which adds the carry from the lower order R1 adder to the sum and carry from the higher order R1 adder. With each pair of R2 adders is associated an R3 adder which performs a similar function, and with each pair of R3 adders an R5 adder. A method of constructing an n-order parallel adder from add-one adders is set out in the Specification. In Fig. 15 which shows a 4 x 4 binary multiplier each line represents a channel carrying two lines one of which is marked to represent a bit. The binary multiplication is performed in circuits To each as shown in Fig. 14. The partial products are summed in pairs in three-bit parallel adders constructed according to the method used in the adder of Fig. 10. The R1 circuits each sum the carry from the adder and the highest order bit of the higher order of the two partial products. The sums of the pairs of partial products are summed in a four-bit parallel adder with an R2 circuit summing the carry from this adder and the outputs of the highest order R1 circuit. This arrangement is generalized in the description to an n x n binary multiplier. Specification 862,178 is referred to.

Abstract: 1345780 Hay-rakes C VAN DER LELY NV 19 April 1971 [20 March 1970] 24775/71 Heading A1F The frame of a hay-making machine having a plurality of rotary, detachable, rake wheels 4, is assembled from a main frame 1 and various sub-frame components into either a side delivery rake or a swath turner, which can be connected to either the front or rear of a tractor and whose working widths may be varied. A side delivery rake which is towed by a tractor (Fig. 2) is assembled from a main frame beam 1 carrying detachable rake wheels 4, whose working pressure on the ground is varied by the operation of a hand crank and spindle mechanism 7 which causes the longitudinal displacement of a rod 6 and hence the adjustment of the biasing force of springs 5 on the cranked shafts 3. The main beam 1 also has three connection points 24, 25, 26 formed by pairs of lugs 27, and a ground castor wheel 9 at its leading end. Arched bars 12, 12A have respective rear ends bolted to the points 25, 26 and their other ends bolted to a vertical sleeve 16 which carries a cranked axle 17 of a ground castor wheel 18. A further ground wheel 22 is arranged at the rear-end of the bar 12A and its plane of rotation is angularly adjustable via mechanism 23 so that the frame will pivot about 17 and hence vary the effective working width of the rake. The main beam 1 is used to assemble a similar rake which is mounted on the front of the tractor 20 (Fig. 6) by means of sub-frame 38 which replaces bars 12, 12A and is connected to the beam at points 24, 26, whilst the rear ends of the frames 1 and 38 are respectively connected via plates 39, 39A to cross beam 40 on the tractor. In this case the working width of the rake is altered by selecting one of a range of possible connecting apertures 40A in the plate 39A. The frame part 38 carries two skids 42 which when lowered support the rake in conjunction with ground wheel 9 when it is detached from the tractor, and a rope and pulley system 43, 44 to adjust the working pressure of the rake wheels when lever 45 is operated from the tractor 20. These two embodiments of a side delivery rake can each be converted into a swath turner by the use of an auxiliary frame part 29A (Fig. 5) which comprises an arm 28 which is connected at its rear end to the main frame 1 and a rake wheel support beam 29, adjustably connected, by means of settings 32, to the front end of arm 28, which carries some of the rake wheels that are transferred from the main frame beam 1. In the embodiment shown in Fig. 5 the auxiliary frame 29A is connected to the main frame at point 24 and 3 clamped to the bar 12, whilst if it is used to convert the front mounted rake shown in Fig. 6, the rear end of the arm 28 is connected to point 25 so that this auxiliary frame is disposed with respect to the main frame 1 in a manner similar to that shown in Fig. 5.
