The soft material 37 may be cork, rubber, foamed material, &c. and the harder material 38 may be plastics, e.g. polyurethane. The soft material 37 may have an upwardly-opening cavity for a pad of plastics-impregnated textiles. The insole may have a top covering 39 of leather, &c. and a bottom covering 40 of leather. plastics, fabric, &c. The shank 38 may incorporate a piece of metal, wood, fibre or a hard rubber bar. The insole may be moulded. A last is described, Figs. 12, 13 having a bottom surface configured to the shape of the top of the insole, for use in the manufacture of the insole. In a modification.

Title: Improvements in or relating to Vehicle Identification Systems.
Inventor: RYLEY JOHN EDWIN
IPC: B61L25/04
Filed: 1967-12-09
Abstract: 1,187,130. Track apparatus. PLESSEY CO. Ltd. 2 Dec., 1968 [9 Dec., 1967], No. 56091/67. Heading B7N. [Also in Division H4] In a vehicle identification system of the type in which a responder carried by a moving vehicle is energized by inductively coupled power from an interrogating unit and produces a serial binary code to identify the vehicle, the data transfer from the responder to the interrogating unit is effected at a carrier frequency derived by division or multiplication of the frequency at which power is transferred to the responder. As described, at the interrogating unit power at a frequency F from an oscillator 1 is transmitted via aerial 2 to the aerial 3 of the responder where it is rectified at 4 to provide power for operating the responder. The frequency F is divided at 5 to supply a carrier of frequency F/A to a phase modulator 8 and is divided again at 6 to provide a clock frequency F/AB controlling a binary code generator 7. The generator 7 supplies a cyclically repeated signal comprising a " start of message " code common to all the vehicles and consisting of a series of binary digits which in their normal or inverted form cannot occur within any of the identification code sequences followed by an identification signal which uses a " two out of five " code. Each time a " 1 " is generated at 7 the modulator 8 phase shifts the carrier by 180 degrees and the modulated carrier is coupled via aerial 10 to aerial 11 at the interrogator unit and supplied to a demodulator 13. A reference signal F/A for the demodulator is supplied by a frequency divider 12 and clock pulses are supplied via a frequency divider 17 which is controlled by a data transition detector 16. A " start of message " code recognition circuit determines whether this code is in its correct or inverted form and if it is inverted applies 180 degrees phase correction to the reference signal derived at 12.

Each word in a matrix associative memory has a unique address field. Each word in the transistorized memory has an erasable data field and a read-only address field, the address fields specifying the word locations and thus being all different. An input register has a data field and an address field, and by masking off one of them an associative search may be done on the data fields or the address fields, the matching word or words being read out to an output register. The output register also receives an indication of the number of matches (0, 1 or a plurality) provided by logic fed by the output of the address fields since in the case of more than one match at least one address bit position will be indicated as being both 1 and 0 (on separate lines) and in the case of no match any particular bit will not be indicated as being either.
