Title: Improvements in portable pneumatic hammers
IPC: B25D9/14
Filed: 1924-09-16
Abstract: 244,519. Keay, R. W. Sept. 16, 1924. Fluid-actuated gears.-In a tool for rivetting, chipping, caulking, rock drilling, &c., fluid is distributed by a valve with four actuating-areas provided by two heads 21, 22 and reduced end portions 19, 20. The end 19 is ported at 19<a> to supply air to the rear end of the cylinder in the rear position of the valve, and the end 20 is slotted at 20<a> to supply air through passage 11 to the forward end of the cylinder in the forward position of the valve. The passage 11 extends the whole length of the cylinder and acts as an auxiliary exhaust passage for the forward end of the cylinder. The valve is grooved at 18 and exhaust passages 13, 14 for the forward and rear ends of the cylinder respectively are put into communication with the exhaust by groove 18 and passages 15, 16 respectively as the valve moves to and fro. The passages 13, 14 have ports 13<a>, 13<b>, 14<a>, 14b controlled by the piston. Compressed air is constantly admitted to the valve end 20 by a restricted passage 8, and to the head 19 by passages 10, 10<a> connected to the inlet. As the piston moves forward, the forward cylinder end exhausts through passages 11, 13, the valve groove 18, and outlets 15, 17. Live air pressing on heads 19, 21 holds the valve rearwardly. When the piston uncovers port 13b to exhaust the rear end of the cylinder, the fall of pressure enables the pressure on the rear end of the valve to throw it forward, and put the rear end of the cylinder to exhaust through the ports 14<a>, 14, groove 18, and outlets 16, 17. When the piston returning uncovers port 14<a>, the forward end of the cylinder is put to exhaust, and the pressure on the rear of the valve is consequently reduced through loss of fluid through passage 11. When port 14<b> is closed, the consequent cushioning together with the excess pressure on head 19 reverses the valve.

Title: Improvements in and relating to rotary liquid meters
IPC: G01F3/10
Filed: 1937-08-12
Abstract: 500,874. Rotary meters. PRECISION METERS, Ltd., and HORTON, F. Aug. 12, 1937, No. 22232. [Class 110 (ii)] The meter comprises two or more chambers 22, 23, each' containing a rotor 40 with a vane 42, which co-operates with an abutment 26 having end flanges 30 and a nose piece 31. A block 10 contains inlet and outlet chambers 13, 14, leading to side ports 17, 18, and 19, 20 respectively. The rotors 40 are displaced angularly 180‹ on a spindle 36, and each vane 42 may have two parts relatively adjustable, for calibration purposes, by means of an eccentric 45 mounted upon a part 39 and seating within an aperture 46 in the second part 40. A light, spring 146 may bias each abutment. A spindle 50 is coupled to the indicating mechanism which is contained within a casing 51. The discharge ports are provided with a portion which extends into the abutment chamber and is never covered by the vanes 42, thus preventing locking of liquid on the discharge side, between the vanes and the abutments. The block 10 may be replaced by a flat plate. A calibration means such as shown in Fig. 4 may be used, comprising a piston 52 in a cylinder 53. The end chambers 54, 55 are coupled by outlets 56, 57 to the meter chambers 22, 23 respectively. Hollow nuts 58 co-operate with stops 59, to limit the travel of the piston 52, thereby adjusting the volumes of the meter chambers 22, 23. To adjust for temperature changes of the liquid, the piston is provided with two heads 52a, 52b, adjustable towards one another. Cup members 160 are connected together by a sylphon bellows 61, and have apertures 62 so that the interior of the bellows is in communication with the annular spaces A, which are filled with liquid similar to that being measured. The meter chambers communicate with the space 63 so that the temperature of the liquid in them is imparted to the sealed liquid within the bellows. Temperature variations cause expansion or contraction of the bellows, to vary the strode of the piston 52. If hot liquids are being metered, a connection 65 leads to the inlet side of the block 10, but in the case of low temperature liquids, the connection 65 is plugged. for metering consumable liquids, such as milk, the meter parts could be made of stainless steel, and the end covers 32, 33 secured by pivoted clamping members to facilitate removal for cleaning purposes. Three or more metering chambers may be used.

Title: Improvements in identification system
IPC: G07C9/00
Filed: 1969-05-01
Abstract: 1,267,996. Releasable fastenings. IDENTIMATION CORP. 1 May, 1969 [14 April, 1969], No. 22233/69. Heading E2A. [Also in Divisions B6 and G1] Apparatus for identifying a person from the length measurements of his fingers, and which may also be arranged to operate the tumblers of a lock, comprises divisions 4, 10, Figs. 2, 3 forming slots for the fingers of a hand and guides for sensors 11-14 which are pushed back by the fingers to slide their ends 11'- 14', Figs. 4, 5, over an opaque identity card 21. The card is personal to the person being examined and has transparent windows 11"- 14" defining a space pattern related through a scale or code to the length of the individual fingers. The sensor ends 11'-14' are spaced axially and related to each other by the same scale or code employed in determining the window pattern for the card, the provision of such a code making it more difficult for an unauthorised person to falsify the security check. Photo-electric sensing devices actuated by the placing of the card in the recess 20 then detect any light passing from a lamp in the housing 6 through the windows in the card, an absence of light passing indicating an identity between the person and the card. In Figs. 8, 8A (not shown) the entire housing (6A) is slid on rails (60) (61) by a motor (M1) instead of the hand itself moving to operate the sensors, and when the sensor (26A) comes into contact with the crotch between the finger and thumb the motor (M1) is stopped and the motor (M2) started to rotate the housing (6A) about pin (71) by means of rack and pinion (73) (74) to bring the sensor (26B) into pressure contact with the crotch between the little finger and the next adjacent finger, whereupon (M2) is stopped. In Fig. 10 (not shown) the hand is first positioned with its first finger crotch in contact with sensor (26A) and then further movement of the hand causes the housing to pivot about the pin (100) to make contact with sensor (26B). In a modification the information on the identification card can be contained in a lock mechanism having pins corresponding to the rods 15 in Fig. 5 and operated by the fingers to control lock tumblers which open the lock when there is identity between the finger pattern and the identity card.
