Title: Improvements in projectile fuses
IPC: F42C1/04
Filed: 1955-03-18
Abstract: 773,570. Projectile fuzes. BOMBRINI PARODI-DELFINO. March 18, 1955 [April 27, 1954], No. 7932/55. Class 9 (1). A sensitive percussion fuze provided with self-destruction means and a delay element preventing arming over an initial portion of the trajectory, has the ignition train of the self-destruction means and/or the delay element within the striker. On firing a projectile provided with the fuze, the percussion cap 2 within the striker 4 sets back by inertia overcoming the resistance of its spring 3 and strikes an apertured member 5 above a delay charge 14 and a compressed gunpowder charge 13. The delay 14 ignites, through a transverse flash passage 6, a charge 15 in a metal latching element 8 which prevents movement of the striker. The explosion of the charge 15 ejects a sealing plate 7 and the element 8 moves out due to centrifugal force thereby releasing the striker 4. A pivoted pawl 10, which blocks the path of the striker, is locked by an inertiaoperated spring or bolt. The striker extends into a recess in the pawl, thus preventing movement of the pawl until acceleration of the projectile ceases. The striker then moves forward freeing the pawl, which is then moved aside by centrifugal force. The fuze is then armed and on impact, the striker is driven inwardly bringing a primer 9 against a perforated needle 12. The primer in turn ignites a detonator (not shown). If the projectile does not hit a target within a given time, the charge 13 burns through and ignites the primer 9 to produce self-destruction of the shell. A metallic disc 1 protects the cap 2, and the body of the fuze may be of moulded synthetic resin or iron.

Filed: 1937-03-16
Abstract: 496,361. Machinery guards. LOVELL MANUFACTURING CO. March 16, 1938, No. 8116. Convention date, March 17, 1937. [Class 80 (iv)] A safety device for wringers comprises handoperated means which, at a touch, release the pressure and stop the drive. Hinged flaps 28 on the waterboards 31 when pressed act on arms 27, Fig. 2, on longitudinal shafts which are thereby rotated to cause arms 24 to press on pivoted latches 20, 52. The former then frees a lever 14 pivoted to the top bar 10. Owing to the unstable position of a toggle lever 16 the spring 9 then causes the top 10 to rise and release the pressure. The latch 52 raises an extension 51, Fig. 10, on a pivoted catch 49 and causes a trip 48 to move away from a clutch lever 45 and allow it, under the force of springs 47, to assume a neutral position in which a dog 40 is out of engagement with either of its associated gears. The drive from the shaft 35 then ceases.

Title: Improvements in and relating to computing weighing scales
IPC: G01G23/18
Filed: 1967-02-21
Abstract: 1,125,269. Weighing apparatus. RELIANCE ELECTRIC & ENG. CO. 21 Feb., 1967 [21 March, 1966], No. 8289/67. Heading G4H. Weighing apparatus comprises a computer for calculating the value of an article according to its weight and price, means for setting up the weight of the article in the computer and photosensitive means for setting up the pre-selected price in the computer. In the embodiment described when the article is placed on a weighing scale 10 (Fig. 1) a lever 11 is lowered to displace a binary coded chart 17 in front of photo-cells 20 so that the outputs from the photo-cells which are fed to the computer 18 represent the weight of the article in binary coded form. The photo-sensitive means for entering the price of the article includes three sets of photo-cells 107-110, 111-114, 115-118 (Fig. 5) positioned behind twelve holes in an article name printing plate 58. Masks (149, 152, 155, Fig. 3, not shown) are positioned to cover selected holes in the plate 58 in accordance with the price of the article so that the outputs from the three sets of photo-cells represent cents, dimes and dollars respectively in binary coded form. Two further photo-cells 170, 171 (Fig. 5) are such that when a perforated printing plate 58 is in operative position in the printer light falls on photo-cell 170 but is masked from photo-cell 171 so that an AND gate 174 is enabled to supply a control signal to further AND gates 177, 178, 179 which are sequentially enabled by pulses from a two stage flip flop. In this way the outputs from the three sets of photo-cells are sequentially applied through OR gates 132-135 to the computer. When an ordinary unperforated printing plate is in operative position however neither of the photo-cells 170, 171 are illuminated by a light source and consequently a "0" output is obtained from AND gate 174. This is inverted by a gate 100 (Fig. 2) to apply control signals to AND gates 83, 84, 85 which are sequentially enabled by the two stage flip-flop so that if the switches of three banks of switches 101, 102, 103 are selectively closed to represent the cents, dimes and dollars of the price of the article, pulses are sequentially gated to the appropriate inputs of a diode matrix 73 the output from which, a binary coded representation of the price, is applied to the computer. In the computer the price of the article is multiplied by its weight and the output together with an output representing the price per pound of the article are applied to check circuits 41 (Fig. 1) which control the driving of the printing wheels till they are positioned in agreement with the output from the computer. Means are included for interrupting or preventing computing if the light source to the photo-sensitive means fails, if it is attempted to set up a digit in excess of 10 in the price selecting means and in the absence of a printing plate.
