Title: Improvements in hydraulic axial piston pumps and motors
IPC: F01B3/00
Filed: 1965-11-12
Abstract: 1,134,882. Reciprocating pumps and motors. ROBERT BOSCH G.m.b.H. Nov. 12, 1965 [Nov. 13, 1964], No. 48032/65. Heading F1A. [Also in Division F2] In an axial piston pump or motor in which the cylinder block engages a valve plate the adjacent surfaces of the valve plate and cylinder block include sealing surfaces surrounding the coacting ports therein and also include thrust surfaces which bear the axial force between the cylinder block and the valve plate during operation. One thrust surface is provided on bearing blocks and/or at least one bearing ring of a good bearing material and having a higher coefficient of thermal expansion than the material of the sealing surfaces which material has a high degree of resistance to wear and pitting and the blocks or ring are of a thickness such that at operational temperature and as a result of thermal expansion the sealing surfaces surrounding the ports are maintained slightly spaced apart from one another by the bearing surfaces. As shown in Fig. 3 the inserts 34, 35, 32 are disposed on each side of the control port 27 in the valve plate and are tapered in the radial direction; the inserts may also increase in depth in the direction of rotation (or in both directions from a centre point in the reversible pumps and motors) so that at working temperatures the bearing surfaces are slightly sloping. Inserts 34', 35', 32' may be fitted in the face engaging the end-cover of a pump. In a modification Fig. 6 (not shown) the end-face of a cylinder block is recessed on each side of the ports and concentric annular bearing rings are located in the recesses. The Specification states that the invention is applicable to working surfaces of other shapes e.g. conical or spherical.

Title: Compound rotary piston type internal combustion engine
Inventor: GARSIDE DAVID WALKER
IPC: F02B53/00
Filed: 1965-11-13
Abstract: 1,070,429. Rotary-piston internal combustion engines. ROLLS-ROYCE Ltd. Nov. 13, 1965, No. 48299/65. Heading F1F. A rotary-piston I. C. engine of the kind including rotary-piston unit having a two-lobed epitrochoidal casing and a three-sided piston planetary rotatable therein, comprises four similar juxtaposed units geared together to run at the same speed with first and second units of equal size and larger than third and fourth units also of equal size. In operation, air drawn into the first unit a, Fig. 3, through a port 20a is carried round by the piston of that unit and transferred through a port 21a, passage 22a and a port 23d to the fourth unit d to be then compressed between the pistons of the first and fourth units and their respective casings and finally compressed by the piston of the fourth unit. When the piston of the fourth unit reaches its "top dead centre" position with compression complete, fuel is injected into the air and the gaseous mixture ignited followed by expansion of the combusted gases to rotate the piston of the fourth unit. The combusted gases leave the fourth unit through a port 24d and are transferred through a short passage 25b to the second unit ft to be further expanded between the pistons of the fourth and second units and their respective housings to do further useful work before being finally exhausted through a port 27b. At the same time, but out of phase by 180, air drawn into the second unit b through a port 20b is carried round by the piston of that unit and transferred through a port 21b, passage 22b, and a port 23c to the third unit c to be then compressed between the pistons of the second and third units and their respective casings and further compressed by the piston of the third unit. When the piston of the third unit reaches its "top dead centre" position with compression complete, fuel is injected into the air in this unit and the gaseous mixture ignited similarly as with the fourth unit, the combusted gases expand in the third unit to rotate its piston and are expelled through a port 24c and transferred through a short passage 25a and a port 26a to the first unit to be further expanded between the pistons of the third and first units and their respective casings to do further useful work before being finally exhausted  through a port 27a. The pistons of the third and fourth units c, d are mounted out of phase by 180 on a common shaft 6c, Fig. 2 (not shown) and the pistons of the first and second units a, b out of phase by 180 on a common shaft 6a with the shaft 6a leading the shaft 6c by 90. If, for any reason it is desirable for the compression and expansion ratios to differ the shaft 6a may be positioned to lead the shaft 6c by any angle between zero and 180 other than 90. The invention enables the expansion and compression ratios to be increased without losing the advantage of a compact and efficient combustion chamber which is in part formed by recesses in the flanks of the pistons of the third and fourth units.

IPC: B41L13/18
Filed: 1962-12-28
Abstract: 1,027,340. Printing apparatus. GESTETNER Ltd. Dec. 12, 1963 [Dec. 28, 1962], No. 8855/62. Heading B6C. In a twin-cylinder type stencil duplicator in which is incorporated an automatic inking mechanism by which a pump supplies ink to the stencil in synchronous operation from the duplicator drive with each ejection stroke of the pump comprising a succession of ink delivery steps, a three-way manually operable switch 18 is provided by which the pump is switched-off, operated in the automatic successive delivery steps manner or actuated to give a full-stroke ejection. For the latter operation the switch 18 has to be held in position. The pump is actuated by a projection 12, Fig. 2, carried by an oscillatable plate 10 which is oscillated from the duplicator drive through an oscillating lever 1 and a reciprocating link 4 such link reciprocation only taking place when a pin 3 carried by the link is engaged in a slot 5 in the lever. This inter-engagement is effected by moving the switch 18 to the position of Fig. 3 whereby a member 8 moving in a plane normal to the plane of the lever 1 causes the pin-and-slot to engage. On moving the switch to the position of Fig. 5 the pin 3 is withdrawn from the lever slot 5 to disconnect the normal automatic # successive steps" delivery operation but simultaneously a supplementary drive comprising a cam 27, reciprocable link 26 and oscillatable link 22 is brought into operation to drive the plate 10, and hence the projection 12, via a vertical reciprocable link 15. This drive causes the pump to eject in a full-stroke delivery action.

Title: Transverse section tomography system and method
IPC: A61B6/03
Filed: 1976-11-26
Abstract: 1527540 Radiography PICKER CORP 26 Nov 1976 [28 Nov 1975] 49449/76 Heading H4F The Specification relates to a data processing system 24 for a computed tomography scanner 22 and provides an output display at 26. The general form of the system is shown in Fig. 1 as comprising a "general processor" 40 and a "special processor" 42 shown in more detail in Fig. 4. The scanner provides time, count (i.e. detector output) and position signals to a central processor unit (C.P.U.) 50 which divides the count signals by the time signals in known manner to provide scan data signals stored in memory 52, a second memory 56 being provided if reorganization of scan data into parallel beam paths is necessary. The C.P.U. (under the control of program controller 54) then performs the following operations. Filtering of the data is done using Fourier analysis or a convolution method, the filtered data being stored at 58. The data are then interpolated to provide signals for angles and positions at which measurements were not made and these are also stored at 58. The scan data stored in 58 are then processed using a back-projection technique in conjunction with "special processor" 42 to build up gradually in array store 70 the final values of absorption coefficients over the area of examination in a form in which they can be supplied to the display 26. The main purpose of processor 42, Fig. 4, is to address efficiently data from the scan store 58 to the array store 70 and it includes an array address calculator 72 which generates a signal representing a selected image point in array store 70 and a scan address calculator 74 for selecting from the scan data stored in 58 those data which are close enough to the selected point to be relevant to the reconstruction of the selected image point in array store 70. A "reconstruction update" unit 76 then combines each datum so selected from the store 58 with the value already stored in 70 and returns the combined value to 70. The scan address calculator 74 is designed to operate incrementally so that succeeding addresses are derived by adding an increment to the preceding address. The complete Specification is an extensive document describing, with the aid of numerous figures, the entire processing system in details which are not susceptible of abridgment.
