Title: Lap roll pressure means for lapping machines
Inventor: LONG JOHN RUSSELL
IPC: D01G27/02
Filed: 1959-03-26
Abstract: 849,322. Lap forming apparatus. GRANITE MACHINE CO., and LIVINGSTON & HAVEN Inc. March 26, 1959, No. 10469/59. Class 120(1). A ribbon lap machine with fluid pressure cylinders maintaining constant equal pressure on the lap pin bearing blocks has means responsive to stoppage of the machine to raise the lap roll from its supporting rolls. As the lap roll 26, Fig. 3 builds up to the desired diameter, an abutment 51 connected to the lap pin bearing block 42 raises a latch 52 and stops the machine. As the latch 52 is raised it engages the lower end of a plunger 115 to permit fluid pressure to build up in the cylinder 104, Fig. 7 of a valve assembly 86 to move a piston 101 and valve plunger 95 thereby exhausting fluid from the upper parts of cylinders 65, 66 to relieve pressure on the bearing blocks 42, 43 and permitting fluid to enter the lower parts of cylinders 65, 66 to raise the bearing blocks 42, 43. When starting the machine, the plunger 95 may be moved by a treadle 97, Fig. 3, even though the latch 52 may still be in engagement with the plunger 115.

Title: Device for the retransmission of signals for a telephone line with two wires
IPC: H04Q1/442
Filed: 1948-04-15
Abstract: 668,369. Two-way transmission. COMPAGNIE INDUSTRIELLE DES TELEPHONES. April 15, 1948 [June 26, 1947], No. 10488/48. Class 40 (iv). A two-way ringing repeater comprises a thyratron incorporating an A.C. ringing source in its anode circuit for each direction and each thyratron in effecting re-transmission of incoming ringing blocks the other and thus prevents oscillation. Ringing currents at o1 o2 after filtering in #0 are rectified and the thyratron lo is fired by the potential across a resistance r1, thus completing the circuit of the ringing current source sfb through transformers ao and bo, the former of which serves as an output transformer and the latter provides additional back bias in the grid of the thyratron le. U.S.A. Specification 1,956,875 is referred to.
Patent GB-394105-A (GB)
Title: Improvements in or relating to automatic or semi-automatic telephone systems
IPC: H04Q3/00
Filed: 1932-04-13
Abstract: 394,105. Automatic exchange systems. ERICSSON TELEPHONES, Ltd., 67, Kingsway, London, and WILMAN, C. W., Ericsson Telephone Works, Beeston, Notting- ham. April 13, 1932, No. 10585. [Class 40 (iv).] In a single-motion 100-point switch, first set by a series of impulses to one of the positions 1 .. 10 and in which the first lines of the corresponding groups are connected to positions 1, 11; 21 .. 91 so that the number of steps to be advanced by the wipers from the preliminary setting to the first line of the corresponding group is a multiple of nine, this advance is effected by transmitting to the switch magnet a plurality of impulse trains each of nine impulses until at the end of one of such trains the wipers are resting on one of the positions 1, 11, 21... 91, all of which are permanently marked. This arrangement obviates the necessity for registering the digit dialled or for marking one of the groups in dependence on the digit dialled. The invention is described with reference to a final selector giving access to groups of lines to private branch exchanges, but is also applicable to ordinary group and final selectors and to directively-controlled call-finders. The number of lines in each group may be other than ten and, within certain limits, may differ for different groups. Detailed operation. Impulses are repeated by relay A to magnet DM in parallel with relay J which on relapse at the end of the digit connects lead 54 to wiper w5 so that at the next closure of cam contact n, relay S operates connecting lead 55 to magnet DM. Series of nine impulses generated by cam M are thus transmitted to magnet DM and at the end of each series earth from lead 54 is connected over wiper w5. When one of the marked contacts 11, 21 &c. is reached at the end of a series, relay J operates over this earth, disconnecting lead 55 and connecting magnet DM in series with relay H, the mid-point of this circuit being connected to test wiper w3. Hunting now takes place in the usual manner and when an idle line is found relay H operates connecting up ringing current and closing a short-circuit around a third winding of the ring-trip relay F to render this sluggish. During release relay F remains operated over cam HA to hold earth on lead 53 and to maintain a circuit for the switch magnet DM until restoration is complete. If all the lines of a group are busy, relay F operates over one of the contacts 10, 20 &c. and wipers w5, w3 to connect up busy lead BF. If the first digit is 1 the operation of relay S energizes relay J immediately over wiper w4 so that lead 55 is not connected up and hunting over the first group connected to contacts 1 .. 10 commences immediately.

Title: Differential voltage responsive apparatus

Filed: 1945-05-03
Abstract: 623,176. Voltmeters. BENDIX AVIATION CORPORATION. May 3, 1945, No. 11240. Convention date, Feb. 21, 1944. [Class 37] [Also in Group XL (c)] An indicator, particularly for use with a radio glide-path beacon, comprises a differential voltmeter to which two potentials are applied in opposition, and means for unbalancing the operation of the voltmeter when both potentials are less than a predetermined value and are thus too small to give a reliable indication on the meter. The invention is applied to an equi-signal overlapping-beam glide-path system wherein the upper of the two beams transmitted by the beacon is modulated at 90 cs. and the lower is modulated at 150 cs. These signals are received in an aircraft by receiver 10, the output of which is applied to the variable tap of resistor 14. The signal developed at one end of the resistor is applied to a filter 16, tuned to 90 cs., the output of which is applied through a step-down transformer 26 to the rectifying network 32. Similarly, the output from the other end of resistor 14 is applied to a filter 18 tuned to 150 cs., whence it is applied through step-down transformer 42 to rectifying network 50. The rectified outputs from the networks 32 and 50 are applied differentially to the voltmeter 52 and the tapping of resistor 14 is set so that when the two signals have equal amplitudes the needle of 52 is not deflected. The output of network 50 is also connected to the cathode of a triode 56, the grid of which is connected through two rectifiers 70 and 72 to the primaries of transformers 26 and 42 respectively, so that upon the receipt of signals of sufficient strength the grid of the triode is biassed negatively and the valve is cut off. If the amplitude of the signals becomes very small, so that unreliable readings would be obtained, the triode conducts, thereby upsetting the balance of the meter 52 and indicating to the pilot that he is not to descend. An additional meter 76 may be used to indicate whether the triode is con. ducting or not and thus whether the beacon signals are being received at sufficient strength.
