Abstract: 876,316. Roller screw-threads; reamers. PLAGEMANN, J., [trading as PEE-WEE MASCHINENUND APPARATEBAU W. PLAGEMANN]. April 29, 1959 [April 30, 1958], No. 14672/59. Classes 83 (3) and 83 (4). In an internal thread-rolling head comprising a mandrel 1, Fig. 1, with rollers 4, having threadrolling profiles, and spaced along one or more pitch curves, recesses 2, 3 crossing each other centrally at right angles are provided in the mandrel half of which, i.e. the recesses 2, accommodate the rollers 4 and secure them against axial displacement while the remaining recesses 3 accommodate bearing spindles 5 of the rollers 4. The profiles of the rollers 4 project above the surface of the mandrel to an extent slightly greater than the depth of the threadrolling profiles. The rollers 4 may be arranged in groups, Fig. 3, the individual rollers of each group being staggered with those of another group and the spacing of the groups being such that the distance axially of the rollers is an integer of the pitch dimension. The leading group of rollers 4 are accommodated in slightly deeper recesses 3a, the rolls of the first group being used to roll the thread to a rough dimension while the second group act as finishing rollers. The rollers 4 are either integral with the spindle 5, Fig. 6 (not shown), or are pressed on to the spindle 5, Fig. 7 (not shown). Guide or truing rollers 6, Fig. 8, are also housed in recesses 7 and 8 in the mandrel and serve to centre the mandrel and to gauge the bore. Bearing units 18, Fig.12, for the rollers 4 and 6 are eccentrically bored so that on inversion of the bearings, the projection of the rollers may be adjusted. Other methods of mounting the rollers in various types of bearings in the recesses are disclosed, Figs. 11, 13, 14 (not shown), using split annular springs, set-screws or hooked springs, provision being made to resist the inclined rolling pressure. In a further embodiment, Fig. 10, a milling cutter or reamer 9 is mounted on the front of the mandrel 1 and rubber seals 11 are provided to prevent chips entering the thread-rolling zone. Liquid is introduced through cross-drillings 13, 14 in the mandrel to cool and lubricate the rollers 4, the tool 9 and the work.

Abstract: 543,682. Servo steering-gear for vehicles, cranes, aircraft and watercraft.. CLARKE, R. E. Oct. 1 1940, No. 14755. [Class 79 (v)] [Also in Group XXXIII] A mechanical servo steering-gear comprises a driving or hand-wheel shaft A, a driven shaft B connected to the parts to be steered, and two power-driven oppositely rotating drums C, D adapted to be selectively engaged by corresponding clutch coils or bands E, F, one end of each coil being connected to the arms LH, RH of a Y member H fixed to shaft A and the other ends of the coils being connected to a pin R on an arm G fixed to shaft B, springs K being provided to keep the arm G normally central between the arms RH, LH. Thus, when the shaft A is turned in either direction, if the resistance to rotation of shaft B is small the torque on A is transmitted to B through one or other of the springs K. If, however, the resistance of B is sufficient to compress the appropriate spring K the clutch coil E or F is tightened on its drum C or D and grips the drum so that the latter drives the coil and the arm H and shaft B is as long as the coil is kept tight on the drum by the continued turning by the operator of shaft A. In the construction shown in Figs. 1 and 2 the clutch coils contract on the external surfaces of the drums C, D; in a modification they expand against the internal surfaces of the drums. The drums are driven at a constant speed through the bevel reversing gearing shown from an external source of power such as an electric motor or any constant-speed shaft.

Title: Improvements in radio filter circuits employing piezo-electric crystals
IPC: H03H9/54
Filed: 1940-10-11
Abstract: 545,804. Impedance networks. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., and STARR, A. T. Oct. 11, 1940, No. 15172. [Class 40 (iii)] In a filter circuit particularly for use between two valve stages in a radio receiver and comprising two tuned circuits L1, Cl and L2, C2 coupled by a piezo-electric crystal PE, it is customary to provide means for neutralizing the static capacity of the crystal, for example a capacity C3 in series with an inductance L3 tightly coupled with L1, as in Fig. 1. The necessity for this is avoided by employing a crystal having two electrodes E1, E2, Fig. 3, on one face connected to the tuned circuits and a third electrode E3 on the other face connected to earth. The two electrodes El, E2 are not necessarily of equal area. It is shown that the crystal is equivalent to the quadripole of Fig. 6, in which the series elements correspond to the crystal PE in Fig. 1 and the shunt elements to the neutralizing circuit. The tuned circuits are normally tuned to the resonant frequency of the crystal, and the band-width of the filter may be altered by tuning them to frequencies on either side of the frequency of the crystal, the capacities C1, C2 being variable for this purpose.

Abstract: 1,183,614. Digital measurement of frequency. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 4 April, 1967 [7 April, 1966; 2 Nov., 1966], No. 15309/67. Addition to 1,143,424. Heading G4H. A system giving an output representing the deviation of an input signal from a specified frequency as described in Specification 1,143,424 is modified as shown in Fig. 1, the time-base signal being applied directly to the first flip-flop FF1 and a gate G N  being provided to combine the reset-to-zero signal for the counter and the output of the flip-flop FF3 to produce a signal opening the gate pair GR 1  and G V1 . The operation is the same as is illustrated in Figs. 2a and 2b of the prior Specification. In another form (Fig. 2, not shown) the counter is initially loaded with a value, and the frequency f i'  Fig. 3A, to be measured is caused to count the counter down towards zero. If this frequency exactly equals a nominal frequency the counter reaches zero at the same instant as the next time-base pulse occurs (period T M ). Fig. 3A shows the condition in which the frequency fi is smaller than the nominal value. At the end of the timed period T M  the counter still has a value Za. Fast clock pulses at frequency f o  are mixed additively with the input pulses f i  and the counter is counted down to zero, in period to which is presented as a pulse length signal representing the deviation. If the frequency f i  is higher than the nominal, Fig. 3B, the counter reaches zero before the end of the period T M . The direction of the counter is reversed so that the counter counts upwards until the end of the period, reaching a value Za. The counter is then counted back to zero by the difference between the frequencies f o -f i , the period ta again signifying the deviation, and a separate signal being given to indicate the sign.

Abstract: 473,033. Agglomerating fuel. JONES, L. E. (Hay, H. C.) June 3, 1936, No. 15477. [Class 50] Fuel of subsoil origin is mixed with liquid, e.g. " Bunker C fuel oil," of insufficient cohesive power to bind the fuel but capable of dissolving components which provide a binder, the mixture being intensively macerated at about the melting temperature of such components until a binding cohesiveness is obtained. In an example, Pocohontas (semi-bituminous) coal is crushed, heated to 200‹ F. or above, mixed with 4¢ per cent of Bunker C fuel oil, and macerated in the presence of live steam for 15 minutes, the cooled product being pressed. Mixtures of bituminous and anthracite coals should include at least 30 per cent of bituminous. The temperature of steam or flue gases fed to the macerator should be such as to maintain the mixture at not less than 200-300‹ F. nor more than 600‹ F., and briquetting is preferably effected at about 150‹ F. Petroleum coke including a residual of heavy asphaltic material is heated to about 190‹ F. and macerated with liquid fuel oil.
