Title: Improvements in or relating to fluid pressure operated percussive tools
IPC: B25D9/16
Filed: 1929-09-05
Abstract: 339,343. Knibbs, R. A., and Wakeford, L. S. Sept. 5, 1929. Percussive hand tools.- In a percussive tool of the type wherein a piston is successively impelled in opposite directions by expanding compressed fluid, two reciprocating valves with large diameter ends opposite to the seatings are arranged in separate chambers, without contact with each other, and each controls the fluid to one end of the cylinder, the cycle being similar to that described in Specification 321,674, [Class 122 (ii), Steam-engine distributing and expansion valves &c.]. The valves may be arranged co-axially with the seats towards each other, coaxially as shown in the Figure, parallel with the seats towards the cylinder, or with their axes perpendicular, or at an angle to each other. The Figure shows the valve 4, controlling the flow of fluid to the lower end of the cylinder, larger in diameter than the valve 3 and provided with a port 14 connected to the space 4<c> and atmosphere through port 15 for relieving compression pressure during the down stroke of the piston. The spaces below the collars of the valves may be connected above and below the exhaust port 13 to assist in opening the valves. The spaces above these collars are connected to the ports 9 and 9a respectively in order to assist in closing the valves. The movements of the valves may also be accelerated by providing these passages with non-return valves 18 and providing the passages 21, 19, 22 and 24 which are in connection with the main fluid supply 5. The movement of the valves may be assisted by springs, and the valves themselves may be of hollow construction.

Title: An improved alidade or sight rule
IPC: G01C1/10
Filed: 1922-10-06
Abstract: 200,002. Potter, A. J. Oct. 6, 1922. Sighting - devices; clinometers; crossstaves.-Relates to the use of a right-angled triangular prism in various sighting - devices. In the application to a sight-rule a base e, Fig. 1, provided with a straight-edge or fiducial line d is fitted with a prism c having the plane of its hypotanuse face b arranged parallel to a plane which is normal to the base and contains the line d, the distance between the planes being preferably such that light incident in the direction of the line d emerges in prolongation of that line after refraction and total reflection in the prism. The prism may be shielded from extraneous light by a sheet-metal hood formed with openings at the front and rear to enable an object to be sighted through and over the prism. For sighting a line at a definite angle to the fiducial line a prism is arranged with its hypotenuse face disposed at that angle to the straight edge of the rule as shown in Fig. 3. In a cross-staff, Fig. 4, a base y carries two prisms w, x with their hypotenuses disposed in planes at right-angles, and a reflector 13, of greater height than the prisms, is secured to the face of the prism w which is directed towards the prism x. To set out a line at rightangles to that joining two stakes, the optical centre of the instrument is placed over one stake, a sight line on the other is taken through and over the prism w, a second sight line is taken through and over the prism x and is observed in the reflector 13, and a third stake is set up by an assistant to be observed in this second sight line. Fig. 6 shows a sight-rule mounted for use as a sighting clinometer. The rule is pivoted at a point 14 in the fiducial line d to a vertical graduated scale 15, and the plumb position of the scale is indicated either by a plumb line or by observing the bubble of a spirit level 16 through the prism c as shown. The level 16 is axially adjustable for this purpose. In the application to a telescope two prisms 20, 21 are arranged in front of the object glass 19 as shown in Fig. 8, or four prisms 27, 28, 29, 30 are arranged as shown in Fig. 12, and the telescope is correctly sighted on a point when the two or four images of the point coincide. The apical portions of the prisms may be removed.

IPC: B44C1/17
Filed: 1929-09-06
Abstract: 333,768. Kaumagraph Co. May 3, 1929, [Convention date]. Transfers.-A transfer consists of a paper base with the design printed in a slowly-fusible composition and overprinted with a more readilyfusible composition, so that in transferring to a fabric, especially one with a complicated weave, by means of a hot iron, the overprinting is transferred first and penetrates and saturates the fabric so that the slowly melting composition cannot penetrate but lies on the top of the fabric. The overprinting is of a dark colour so that, when transferred to the fabric, the design shows as a light colour on a dark ground. The overprinting is effected with a known composition, consisting, for example, of rosin, beeswax, and ultramarine. The design is printed with a cellulose product such as ethyl or benzyl cellulose, which is relatively infusible, combined with a fusible substance such as a resin and with high-boiling point solvent or plastifier such as tricresyl phosphate, In an example, the composition consists of ethyl oellulose, cumarone resin, ethylene glycol mono-ethyl ether, ethyl abietate or tricresyl phosphate, and lithographic varnish.

Title: Improvements in and relating to navigational calculating instruments
Inventor: MCLELLAND THOMAS POLLOCK
IPC: G06G1/00
Filed: 1956-09-07
Abstract: 825,228. Calculating-apparatus. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Sept. 2, 1957 [Sept. 7. 1956], No. 27407/56. Class 106 (1). Calculating apparatus for predicting the shortest future distance between two relatively approaching objects, such as ships, given two successive values R 1 , R 2  of the range of one ship from the other and the corresponding change in bearing a, comprises two relatively movable members, one of which bears a reciprocal scale of range and the other of which bears a set of reciprocal scales graduated according to the shortest distances of approach for different values of the change in bearing. The latter set of scales may be replaced by a set of curves passing through points of equal value on the set of scales. It is shown that, as an approximation, the shortest distance of approach d=sin α/R 2 <SP>-1</SP> - R 1 <SP>-1</SP>) and consequently the shortest distance of approach scales are calibrated to take account of the factor sin a. Then, if R 1  on the range scale is aligned with the datum line from which the other scales are drawn, the required value d may be read on the appropriate shortest distance scale opposite the value R 2  on the range scale. In one embodiment, Fig. 3, the range scale 8a is marked on a stock member 8 and the other scales 9a on a slide 9. Eight scales 9a provide for changes in bearing angle from “‹-2‹ at “‹ intervals. A cursor 10 facilitates reading. In another embodiment, Fig. 1 (not shown), the shortest distance scales are drawn radially on a disc and the range scale is marked on a bar pivoted at the centre but slidable relatively thereto. In this case two alternative range scales are provided and co-operate with alternative sets of shortest distance scales. In another arrangement, Fig. 2 (not shown), the range scale is marked round the periphery of a disc rotatable on a base member in which moves a slide bearing the set of shortest distance scales, in this case arcuate, a selected one of which may be moved into juxtaposition with the range scale. In a fourth embodiment, Fig. 4, curves 11a of equal shortest distance values are marked on a drum or endless band 11 in a casing 15 having a window 15a through which the change in bearing value corresponding to the portion of the curves visible through a window 15b may be read. The range scale is marked on an endless band adjustable by a knob 14a and also passing across the window 15b.

Filed: 1973-06-11
Abstract: 1428470 Data processing system SIEMENS AG 11 June 1973 [26 July 1972] 27668/73 Heading G4A A data processing system includes a plurality of processors and a plurality of stores interconnected by an input/output control unit having a plurality of data channels, the processors and stores each being arranged in a number of groups equal to the number of data channels, the arrangement being such that requests for access to the stores and processors are evaluated in terms of the priorities of the requesting units and in terms of their targets, and a number of non-conflicting requests, up to the number of data channels, are honoured simultaneously. As described four groups A-D each of four processors are provided together with a similar arrangement of stores W1-Z4, the stores and processors being interconnected via four channels in an input/output unit (input and output being relative to the stores). The processors make requests by providing a request signal and a store address which inter alia identifies the group of stores concerned. Requests are not considered if the requested store is operating in response to a previous request nor if a store cycle is being performed in a different store group for the requesting processor. Two modes of selection are described. In the first the processors within each group are arranged in descending priority 1-4 and in each operating cycle the highest priority processor in each group is selected. In the event that more than one selected processor is requesting the same store group the requests are eliminated on the basis of a descending order of priority amongst the processor groups A-D. In this way up to four requests can be honoured simultaneously. In the second mode each group of stores has a selector which selects the highest priority processor requesting the associated group, the processors being arranged in descending priority order A1, B1, C1, D1, A2, B2 ... D4. When a processor is selected all requests from processors of lower priority in the same group are removed to prevent these processors needlessly blocking other requests to groups of stores other than the group requested by the selected processor. Both arrangements allow pairs of processors to be connected in redundant pairs, corresponding processors from groups A and B and groups C and D being so connected, i.e. A1, B1. Central comparators V AB , V CD  for processor groups AB and CD are activated by a signal indicating redundant operation and in the event of inequality a "compulsory read out" signal is supplied to the stores. The data supplied by the two processors is error checked, e.g. by parity circuits, only correct data being used. The pairs of processors also have comparators for store access requests. The arrangements for servicing requests from the stores are generally similar to those described above.
