Title: Improvements in or relating to a pneumatic hammer
Inventor: SMALLPIECE COSBY DONALD PHILLI
IPC: B21J7/24
Filed: 1964-10-06
Abstract: 1,024,340. Fluid pressure hammers. MAR. TONAIR Ltd. Oct. 6, 1964, No. 40648/64- Addition to 868,771. Heading B3H. [Also in Division B4] A pneumatically-actuated hammer comprises a piston 15 movable in a cylinder 2 having an inlet and outlet port 30 at one end and a port 6 at the other end communicating with an air reservoir 1 which is provided with an inlet and outlet port 31, the arrangement being such that when air is fed through the inlet 30 and the port 31 is connected to exhaust, the piston moves until the port 6 is sealed by the piston and, upon subsequent reversal of the air flow, the air pressure in the cylinder drops below that in the reservoir so that when the seal between the port 6 and piston is broken, the pressure in the reservoir is applied to the entire area of the piston so as to cause a sudden outward stroke constituting a hammer blow. The piston is provided with a rod 10 for connection with a tool bit and also with a resilient ring 19 for sealing the port 6. In operation, with a control valve 32 in the position shown, air is fed through lines 33, 37 non-return valve 54 and port 30 into the cylinder to move the piston into the position shown, the reservoir being connected to exhaust via port 31, lines 36 and 34. Upon reversing the position of the spool 70 of the valve 32, air is fed to the reservoir, the air in the cylinder being exhausted via port 30 and a pressure regulating valve 50; the pressure-regulating valve is set so that the force acting on the inner side of the piston is greater than the force acting on the area of the piston defined by the port 6. In order to cause the piston to be driven on a hammer stroke a pulse of compressed air is fed via a valve 58 and port 56 to act on the top of the piston thereby breaking the seal so as to permit the full pressure in the reservoir to act on the entire area of the piston. The valve 32 may be operated automatically in synchronism with the movement of the piston as disclosed in the Parent Specification and the valve 58 may be operated automatically by a device responsive to the pressure in the cylinder or reservoir.

P N  in turn to a word register RP in which each is converted from parallel to serial form and transmitted Us, Mt to a central station, and in a receiving phase words received Mr, Is from the central station are converted from serial to parallel form in the word register RP and passed to an address comparator CI which, on recognizing its address, authorizes I the transfer of (the rest of ) the received message to output devices A e.g., via a memory MV. The address is a succession of words, and the comparator CI, which stores the address of the transceiver, is controlled by the counter CP. A decoder DT recognizes the first word received as a sync. word to produce a signal S, and decodes each subsequent word from binary to 1-out-of-10 form before passage to CI, MV, these subsequent words being two address words and two control words. UC is control logic, GC is a timing generator, and T is a gate unit.

Patent GB-1049679-A (GB)
Title: Data storage system
IPC: H03K17/58
Filed: 1963-10-18
Abstract: 1,049,679. Tunnel diode bi-stable circuits. STANDARD TELEPHONES & CABLES Ltd. Oct. 18, 1963 [Oct. 19, 1962], No. 41239/63. Addition to 1,021,859. Heading H3T. [Also in Division G4] The tunnel diode bi-stable circuit of the parent Specification is modified to provide non- destructive sensing by varying the constant current supply. Fig. 6 includes at 110 the basic prior circuit in which during the low voltage condition of the tunnel diode 102 the current from the constant current source flows through the tunnel diode and during the high voltage condition it flows mainly through the ordinary diode 101, the tunnel diode current being in the valley region. Switching from the high voltage to the low voltage condition is effected by applying half-amplitude pulses simultaneously to windings 111-1 and 111-2. The switching of the tunnel diode induces a voltage in the winding 111-4 and this may be used to check that switching has been effected. According to the present invention, non-destructive sensing may be effected by decreasing or slightly increasing the value of the constant current so as to shift the load line provided by the ordinary diode from its normal position (4), (Fig. 2, not shown), to (12) or to a position a little below the peak point. This causes a substantial change of tunnel diode current only if it is in the high voltage state A and this change produces an output voltage in winding 111-4. Resetting to the low voltage state may be effected by increasing the constant current supply to a value I 0  above the peak current. The three values of current to provide " hold," " non-destructive read out " and reset may be obtained by operating switches 114-1 and 114-2. The circuits may be arranged to form a matrix store (Fig. 9, not shown), the current controlled switching to the low voltage state and also sensing being effected in columns by switches 9 and 11 and voltage controlled switching to the high voltage state being effected in rows by connecting the windings in series.

Suitable aromatic disulphonyl chlorides are the benzene-, the biphenyl-, the arylsulphone- and the aryl ether-disulphonyl chlorides.  The units (3) may be obtained by reacting an aliphatic dicarboxylic acid chloride, e.g. a chloride of malonic, oxalic, succinic, glutaric, adipic, pimelic, suberic, azelaic, or sebacic acid, or cis or trans 1,4-cyclohexane-, 1,3-cyclohexane- or 1,3-cyclobutane-dicarboxylic acid, with a glycol, e.g. ethylene, propylene, isobutylene, tetramethylene, pentamethylene, 2,2-dimethylpropylene, hexamethylene or decamethylene glycol, or 1,4-dimethylol-cyclohexane.

The units (3) may also be prepared by treating a carboxyl-terminated polyester (from a glycol and excess dicarboxylic acid) with e.g. PCl3, PCl5 or SOCl2, or by treating a low molecular weight hydroxyl-terminated polyester with excess dicarboxylic acid chloride.  For reaction with the diphenol solution, the acid chloride mixture is preferably dissolved in an inert organic solvent, e.g. CH2Cl2, C2Cl4, C2Cl4H2, CHCl3, CCl4, o-C6H4Cl2.  A basic organic catalyst may be added, e.g. benzyltrimethylammonium chloride. In examples, acid-chloride-terminated polyesters from adipyl or azelayl chloride and neopentyl glycol or succinyl chloride and hexanediol are mixed with isophthalyl chloride, terephthalyl chloride, and 4,41-biphenyldisulphonyl chloride in CH2Cl2 and reacted with a solution of bisphenol A in aqueous NaOH in the presence of benzyltrimethylammonium chloride.

Rubble filled, stone &c faced structures, such as walls or columns are repaired by feeding grout through an opening in the facing material A whilst a fluid tight membrane E is held in close engagement with the facing by the pressure of fluid enclosed adjacent to the membrane E, for example by an outer skin E<SP>1</SP> forming with the membrane E an air tight bag, or by a separate air filled bag, the fluid pressure being high enough to prevent escape of grouting material through fissures in the facing and to prevent outward movement of the facing material. The structure may be repaired in sections, from the bottom upwards each section being sealed, if ;grout needs to be introduced under heavy pressure, by a plate D introduced after access to the interior has been established with the aid of supporting piers B. the piers B and additional reinforcement threaded through the piers being subsequently embedded in concrete used to make good the cut away portions of the facing material. If gravity can be relied upon to ensure that grout will percolate through existing rubble fillings. there is no need to cut opening through the facing for insertion of plates D, and the grout can be introduced under light pressure through a small hole at the top of the section.
