Title: Improvements in and relating to the handling of fibrous cement sheets
Inventor: BEK STEEN JACOB
IPC: B65H3/08
Filed: 1963-02-18
Abstract: 966,957. Feeding sheets. F. L. SMIDTH & CO. A.S. Feb. 18, 1963, No. 6482/63. Heading B6B. [Also in Division B8] In apparatus for separating sheets by suction from the top of a stack consisting of partially hardened fibrous cement sheets alternating with separator sheets, the suction lifting device has a downwardly open suction chamber of substantially the same dimensions as the sheets and has curved supports therein, so that when a sheet is grasped it is curved to produce shearing forces between the sheet and the sheet immediately below to facilitate the separation. As shown in Fig. 1, a carriage 2 is reciprocable along a runway 1 and carries two vertically movable suction devices 3, 4 having open-ended suction chambers 5, 6, respectively. Initially, there is a single central stack 7 of alternating steel and fibrous cement sheets on a support 10, and the chamber 6 is lowered to grasp a steel sheet and then rise with the sheet. The carriage 2 is moved to the right, the chamber 6 is lowered to deposit the steel sheet on a support 10 to form a stack 9, and the chamber 5 is lowered to grasp a cement sheet on the central stack. Both chambers rise, the carriage is moved to the left, and both chambers are then lowered. The cement sheet is deposited on a support 10 to form a stack 8, the chamber 6 grasps a steel sheet on the central stack, and a fresh working cycle commences. The suction chambers are about the same size as the sheets, the supports inside the chambers comprising spaced transverse ribs within the open faces against which the sheets are sucked and curved. The steel sheets are curved convexly by the chambers 6, and the cement sheets are curved concavely but to a lesser degree, to ensure separation from the stack 7. In a modification, the support ribs 17, 18, Fig. 10, are arranged longitudinally, and certain ones, such as 18, are arranged to move upwardly when engaged by a sheet, and thus cause the sheet to be curved. Where the cement sheets, such as 12, Fig. 10, to be separated are corrugated, the edges 15 of the chamber are also corrugated at their outer edges; and in the case of fixed transverse support ribs, the edge faces of the ribs are corrugated. Fig. 12 shows a single lifting device having two suction chambers 20 which can separate sheets from the tops of two abutting stacks and then deposit these sheets on two stacks which are separated by a suitable distance. The chambers 20 are suspended in a guide 21 for horizontal movement by compressed air cylinders 23. Suction is applied to one chamber through a pipe 25, and the two chambers are connected by a flexible pipe 24 which allows the chambers to be moved apart so that the two sheets can be deposited on two separated stacks. The stack supports 10, Fig. 1, may be fixed pallets, but may be movable conveyer belts or trucks.

Title: High-frequency attenuator and divider circuits
IPC: H03H7/24
Filed: 1944-04-06
Abstract: 587,576. Impedance networks. PHILCO RADIO & TELEVISION CORPORATION. April 6, 1944, No. 6514. Convention date, May 13, 1943. [Class 40 (iii)] [Also in Group XXXV] An attenuator and voltage-divider for u.h.f. signals is so constructed that the source E, Fig. 1, of signals is unaffected by changes in the load or in the apportionment of the energy between two outgoing lines T1, T2. The primary inductance L1, Figs. 1, 3, which may be a tank coil or anode load, is electrostatically screened' by a shield structure 3 from the secondary inductance L2 and is magnetically coupled to it through an aperture 2 in the screen which restricts the degree of coupling. The inductance L2 preferably comprises a single turn, and a selected point on it is earthed through a wiper 1 which may be a plated steel spring and be pivoted as shown so as to provide a wide range of variation. The apportionment of energy between two outgoing earthed lines T1, T2 depends on the setting of the wiper. The shunt resistances R3 are made low (e.g. 100 ohms) and the series resistances R2 high (e.g. 1000 ohms) in order that the load. may not react on the source E. For the same purpose the input and output ends of the resistances R2 are screened from one another. The shape of the characteristic curves relating to the setting of the wiper 1 with the voltages applied to the lines T1, T2, and the maximum values of those voltages, depend on the size of the aperture 2 in the screen 3. These characteristics, Figs. 4, 5, 6 (not shown), may also be altered by shaping the loop L2 or by earthing the mid-point of the shunt resistance R1 and altering its value as compared with the impedance of the inductance L2. The device may be modified for use simply as an attenuator, one of the lines T1 T2 being suppressed.

Abstract: 1463762 Regulating IC engines HONDA GIKEN KOGYO KK 13 Feb 1974 [14 Feb 1973] 6584/74 Heading F1B An internal combustion engine including an auxiliary combustion chamber 4 communicating with a main combustion chamber 2 via a frame passage 3 is characterized by means for automatically varying the effective size of the flame passage in response to the operating conditions of the engine. The means comprises a valve skirt 17 having an aperture 16, the skirt being attached to an auxiliary intake valve-member 8. The valve-member recipro-  cates to open and close the intake passage and rotates according to the load on the engine, the rotation being effective to change the overlap between the aperture 16 and an aperture 14 of the flame passage 3. The output of a load detecting device (22), Fig. 2 (not shown) is applied to a shaft 18 which is movable axially to cause rotation of the arm 20 of the valve-member 8 by virtue of an arm 19 of the shaft engaging lugs 21 of the arm 20. The load detecting device comprises a diaphragm (24) defining a chamber the pressure in which is controlled by a three-way solenoid valve (27). A pair of switches (33, 34) respond to the speed of the engine and throttle movement respectively either of which, when open, cause atmospheric air to enter the chamber. When both are closed, vacuum is applied to the chamber. The shaft 18 is connected to the diaphragm (24). The valve-member 8 may be rotated by a rack and pinion (39, 37) Figs. 5 and 6 (not shown) with the rack connected to an accelerator pedal (41) or a manifold vacuum operated device (47). The skirt may have a notch (54), Figs. 13-15 (not shown), to prevent any restriction of the flame passage when the valve-member 8 is in its axially open position regardless of its angular position.
